Rajashekara, Shruthi. "A Qualitative Assessment of Healthy Food Access in Navajo Nation." Thesis, Harvard University, 2014. http://nrs.harvard.edu/urn-3:HUL.InstRepos:13041351.
Full textAbstract:
Background: The Navajo population experiences high rates of food insecurity, contributing to high rates of chronic disease. We conducted in-depth interviews with Navajo tribal members in order to understand food insecurity in this community and inform the design of an intervention to improve access to healthy foods.
Methods: Thirty individuals were interviewed over a three-month period, including Chapter House officials, Community Health Representatives and heads of households living in the Crownpoint Service Unit in Navajo Nation. Data was coded, grouped into analytical categories and integrated into a thematic framework.
Results: Food insecurity in Navajo Nation demonstrates variability at the structural, community, and individual and household levels. Income, transportation, vendors, Chapter Houses, social support and health literacy were the main factors contributing to participants’ access to healthy foods. Responses to food insecurity were explored through coping strategies as well as through food purchasing strategies such as price, proximity, shelf life, family preferences, and ease of preparation. Lastly, participants discussed their endorsement for a proposed intervention to increase access to healthy foods.
Conclusion: Food insecurity in Navajo Nation is a complex issue, influenced by the dynamic relationship between determinants of individual behavior and the broader environmental context in which they are embedded. A community-based multi-level intervention is necessary in order to achieve sustainable improvement in access to healthy foods.

Full textAbstract:
The General Organization for Technical Education and Vocational Training, Riyadh, Saudi Arabia, has developed a special feeding program for the students at its institutions. The effects of this program on the nutritional and health status of these students have not been evaluated yet, and since no published dietary research has been performed on Technical and Vocational young adult male students, the present work was undertaken to investigate the nutritional status of this community in Riyadh, Kingdom of Saudi Arabia. After a pilot survey, it was decided to use a selfcompleted questionnaire combined with personal interview to investigate the nutritional status of 690 students randomly selected from the study population. Dietary data was collected by two methods: usual weekly intakes "diet history" and actual daily intakes "diet diary". The nutrient intakes were calculated using the unilever Dietary Analysis Program (UNIDAP). The statistical Package for the social Science (SPSS/PC+) was employed to analyse the data; statistical significance of relationships between certain sets of data was determined by chi-square analysis. Some general factors affecting the nutritional status of these students were identified, their nutritional habits and attitudes were investigated, and the average daily intakes of energy, the macronutrients, and selected micronutrients were calculated. The main results of this study shows that the majority of the study population are adolescent, moderately active individuals, and have lower than the standard range of the Body Mass Index; anaemia is the most stated health problem; meal-skipping and eating between meals are common habits amongst the students. Regarding nutrient intake, there was an energy, polyunsaturated fat, and vitamin C deficiency; adequate intake of saturated fat, dietary fibre, retinol, and zinc; more than adequate intake of protein, total fat, cholesterol, thiamin, riboflavin, calcium, and iron. Recommendations are given which aim to improve the nutrition of technical and vocational students.

Russell, Caitlin. "The Effectiveness of a Short Food Frequency Questionnaire in Determining the Adequacy of Vitamin D Intake in Children." Digital Archive @ GSU, 2010. http://digitalarchive.gsu.edu/nutrition_theses/18.
Full textAbstract:
Background: Studies have consistently found a high prevalence of vitamin D deficiency in adolescents. Few validated dietary intake assessment tools for vitamin D exist for adolescents.
Objective: The aim of this study was to determine if a short food frequency questionnaire (SFFQ) can be used to effectively assess vitamin D intake in adolescents compared to a previously validated long food frequency questionnaire (LFFQ).
Participants/setting: 140 healthy 6-12 year old (male n=81) Caucasian and African American (n=94) children from Pittsburgh, Pennsylvania completed a SFFQ and LFFQ at two time points 6 months apart.
Main outcome measures: Reliability and validity of a SFFQ by comparison with a previously validated LFFQ for children and adolescents.
Statistical analysis: Reliability, validity, sensitivity, specificity, positive, and negative predictive values were assessed using Pearson correlation coefficients.
Results: Mean vitamin D intake from the SFFQ (range, 434 to 485 IU) was higher than the LFFQ (range, 320 to 378 IU). Overall association between the SFFQ and the LFFQ for vitamin D intake was modest (r=0.36, P<0.001). When stratified by race, the overall degree of association was weak for African Americans (r=0.26, P=0.001) and moderate for Caucasians (r=0.57, P<0.001). Overall reliability testing results were modest and significant for the LFFQ (r=0.28, P=0.002) and SFFQ (r=0.33, P<0.001). Association between mean vitamin D intake from LFFQs and SFFQs was used to determine validity. The association for validity was found to be modest (r=0.51, P<0.001). Sensitivity, specificity, positive predictive value, and negative predictive value for the SFFQ were 90%, 64%, 0.78, and 0.58, respectively.
Conclusion: The SFFQ was found to be modestly valid and reliable in an early adolescent population. Associations between African Americans were not as strong as Caucasians which may be due to errors in reporting dietary consumption related to higher body weight.

Full textAbstract:
The purpose of this study was to determine the needs and relationships of high-risk community members in Cocke County Tennessee to food sources. Cocke County was chosen as the representative county in this pilot study due its high percentage of residents living at or below the poverty level, which can lead to hunger and food insecurities. A community food assessment was conducted among residents participating in a commodities disbursement program in Cocke County. Two hundred seven individuals participated in this survey. The results of the surveys were posted and analyzed using an online statistical analysis software program. With the needs of the Cocke County community identified, steps will be taken to implement a plan of action and the results from this study will also be used as a model to identify needs in both Greene and Hancock counties as well as other counties in the Northeast Tennessee region.

Full textAbstract:
The first aim of this dissertation was to validate the 24-hour recall method of dietary assessment and to identify possible sources of error and bias in a cross-cultural sample of South African women. The second aim of this dissertation was to determine the source and extent of inter-researcher variability associated with the interpretation of food intake records. The first study was designed to consider whether reporting error is dependent on individual subject characteristics such as ethnicity, body mass, body fatness, age and education, or whether it is due to the dietary assessment tool (i.e., the 24-hour recall). In this study 118 women (25-55 years old) representing different ethnic and language groups (51 Xhosa-speaking, 31 Afrikaans-speaking, 36 English-speaking), different job types ( 25 unemployed, 25 general assistants, 52 medics and para-medics and 16 administrative personnel) and different levels of education (5 with 6-7 years of schooling, 35 with 8-10 years of formal schooling, 43 with 11-12 years of formal schooling and 35 with post high school diploma or degree) consumed a meal that was based on what they reported to habitually eat. All food and beverages consumed were covertly weighed and this was compared to a 24- hour dietary recall performed on the following day. Results of this study showed that the overall variance in reporting error was low. The error was, however, nutrient specific and was related to certain subject characteristics. Under-reporting was greater for subjects with a higher percentage body fat mass and a greater body mass index. Subjects with a lower level of education were more likely to under-report absolute carbohydrate (g) intake, whereas subjects with a higher level of education tended to under-report dietary fat. Subjects with a greater knowledge of food and nutrition were more likely to under-estimate protein intake and overestimate carbohydrate intake. 'Seasonality' (fluctuations in food purchases due to income) affected body mass, socio-economic status and dietary reporting error. Under-reporting of fat intake (g) was greatest in subjects that experienced the most fluctuations in income. In the second study of this dissertation, three post graduate students in dietetics independently assessed and analyzed ten, 3-day food records. The specific areas of variability that were studied related to (i) the selecting of food names/codes on the computer dietary analysis program, (ii) the keying of data from the written dietary records (clerical errors) to the data storage file and, (iii) the conversion of food consumption quantities to gram weights (judgment errors). There were no systematic differences in the variability amongst dietitians in interpreting and analyzing dietary data in this study. The mean coefficient of variation for added sugar was 14.8 ± 12.6 (g) and for fat 7.1± 5.2 (g). In one subject, the range of difference in fat (kJ) intake assessed by the dietitians was as high as 1313 kJ. Conclusions: 1) Adiposity is a universal predictor for under-reporting of dietary intake. 2) Inaccuracies in dietary reporting are nutrient specific and may be influenced by social desirability bias (through education or knowledge of food), language, familiarity with certain foods and 'seasonality' in food purchases. 3) These same factors influence the choices of food and beverages that subjects make in a 'test meal' that is used to validate dietary intake 4) The variations in interpretation of the quality and quantity of reported food intake by the measurer is a source of experimental error that cannot be ignored and which may account, at least partially, for the difference between true and reported intake.

Merrill, Cathy A. "Family and Consumer Sciences Teacher Needs Assessment of a STEM-Enhanced Food and Nutrition Sciences Curriculum." DigitalCommons@USU, 2016. https://digitalcommons.usu.edu/etd/5216.
Full textAbstract:
Science, technology, engineering and mathematics (STEM) education concepts are naturally contextualized in the study of food and nutrition. In 2014 a pilot group of Utah high school Career and Technical Education Family and Consumer Sciences teachers rewrote the Food and Nutrition Sciences curriculum to add and enhance the STEM-related content. This study is an online needs assessment by Utah Food and Nutrition 1 teachers on the implementation of the STEM-enhanced curriculum after its first year of use in 2015-2016. A Borich needs assessment model was used to create mean weighted discrepancy scores between teacher-perceived levels of importance and teacher-perceived competence for each objective in the new curriculum in order to prioritize professional development needs felt by the teachers. The survey also gathered data on educational backgrounds, teaching experience, demographics, and recommendations from the teachers about barriers and aids to implementation. While it was found that teachers felt moderately competent to teach the new curriculum, the most needed areas of professional development were in the objectives with the highest concentration of STEM-related concepts. In order bring teacher feelings of competence up to the levels of teacher perceptions of the importance of these STEM-related objectives, teachers need to deepen their own knowledge of STEM education concepts through substantive, on-going professional development. Focused webinars and facilitated online collaborations for the teachers would call attention to new and previously missed resources and help the teachers apply them in the classroom.

Full textAbstract:
Undernutrition is a major public health problem, contributing to 33% of deaths in infants and young children globally. In Kygryzstan, Central Asia, Mercy Corps provided 6 metric tons of rice, flour and oil as well as nutrition education to kindergartens in 40 rural regions, serving 41,000 children, for one year. Anthropometric measurements were collected at the beginning and end of the program (10 months later). Children, who were stunted, wasted and underweight at baseline, recovered by follow-up, with rates of recovery of 50%, 65% and 50%, respectively. The prevalence of stunting, wasting and underweight in the population decreased from 13.8%, 3.4% and 3.2%, respectively, to 8.6%, 2.1% and 2.3%, respectively. These results are particularly significant as the dearth of research on pre-school feeding’s impact on growth and nutrition has led to this particular intervention being deemed ineffective for improvement of nutritional outcome.

Full textAbstract:
This study compared feed lot finished beef and grazing standing corn beef from young steers for sensory acceptance, sensory quantitative descriptive analysis attributes palatability and WarnerBratzler shear force values. In comparing both feeding treatments results indicated no differences (P > 0.05) between feeding treatments for all attributes including appearance, aroma (with handheld) and (with sniff bottle), texture, flavor and basic taste. However, there was difference (P < 0.05) in flavor, off-flavor for different feeding systems by panelists. Analysis of variance for Warner- Bratzler shear force values revealed no differences (P > .05) between steaks from two treatments. Based on this research, the meat industry may wish to provide the consumer with the option of choosing beef that was traditionally feed lot finished or beef finished by grazing standing corn. Thus, grazing standing corn beef producers could utilize a practicable alternative feeding system with niche market appeal to represent a viable production option.

Meyer, Samantha. "Time to Get Real: A Food Assessment of Dining at Pomona College." Scholarship @ Claremont, 2010. http://scholarship.claremont.edu/pomona_theses/8.
Full textAbstract:
Pomona College is an institution deeply committed to sustainability and student well being; however these commitments are not reflected in the College’s food purchases. Before this study, an assessment of purchasing had not been conducted at Pomona College. Using the Real Food Calculator – a metric designed to evaluate food purchasing at academic institutions – I tracked all food purchased by one of the College’s dining halls over the course of one month. Each food item was assessed based on the potential health concerns of its ingredients and whether the item was locally produced, ecologically sound and/or humane to determine whether it should be considered Real. The assessment metric also lists ingredients with potential health concerns (including trans fats, high fructose corn syrup, MSG, and others), which if present in the food item mean it cannot be considered Real.
Of the over $150,000 worth of food purchases made during the study, 8.9% qualified as Real Food. Each food that qualified as Real Food met the standards for at least one of the attributes (local, ecologically sound, or humane). A total of 2.1% of all food purchases qualified for two attributes. Of the foods assessed, over one third contained ingredients considered harmful to human health. If Pomona is serious about its commitments to sustainability and student well being, it is time to include food purchasing in these discussions. The study concludes with a series of recommendations to improve food purchasing at Pomona College.

In this participatory action research study, an Empowerment Process Model (EPM) was tested for the development of feasible action plans that addressed the priority concerns and the implicit food and nutrition problems of village families within their current socio-economic and political context. The Visual Verification Survey (VVS) was used to test the EPM results and its usefulness with similar participants. An EPM with 24 village women and a VVS with 68 village women were purposefully sampled in two locations in Dominica, West Indies, along with key informant interviews with eleven agency leaders to identify, prioritize, and describe their perceptions of villagers' life problems, the root causes of the problems, and solutions. This community-based approach used participatory non-written activities and locally developed visual aids to empower Dominican women to develop feasible action plans: a sewing workshop, how to start a business workshop, coffee house project, and women's group. Thematic content analysis and participatory activities were used to identify the themes and "give voice" to the participants' perceptions of top prioritized life problems: unemployment and economic issues, alcohol and drug abuse, lack of educational services, and teenage pregnancy. When specifically asked, the women identified basic health, food, and nutrition concerns, such as a steady income to buy food, a variety of foods to maintain health, and an accessible, clean water supply. The study revealed substantial differences in the rankings between the EPM and VVS women. The differences may have been influenced by the women's educational level, family situation, and previous involvement in community activities and leadership roles. Similar top prioritized root causes associated with many life problems by the women included lack of educational services, facilities and qualified teachers; and girls exchanging sexual favors for money or possessions. Overall, key informants and the Dominican women participants had similar perceptions of prioritized life problems of typical Dominican families. The results of the research demonstrated the need for site-specific programs and assessments using participatory non-written activities to engage a variety of women and to satisfy their diverse needs and locations. To become effective and sustainable, nutrition programming should be integrated into overall life problems.Ph. D.

Full textAbstract:
Thesis (MVoeding)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: Objectives and scope of investigation Following the 1996 recommendations of a FAO/WHO expert panel for the development of food-based dietary guidelines (FBDGs) unique and specific to the needs of the populations of different countries, a South African FBDG Working Group was formed and ultimately also a Paediatric FBDG (PFBDG) Working Group with the task of the latter being the development of FBDGs for children younger than 7 years. A set of preliminary PFBDGs, chosen to address the most pressing paediatric public health issues, namely protein-energy malnutrition, micronutrient deficiencies and infectious diseases, were formulated for each age group sub-category (0-6 months, 6-12 months and 1-7 years). The following set of preliminary PFBDGs for the age group 6-12 months were approved by the Working Group to be subjected to consumer testing: • Enjoy time with your baby • From six months start giving your baby small amounts of solid foods • Gradually increase your baby’s meals to five times a day • Keep breast feeding your baby • Offer your baby clean, safe water regularly • Teach your baby to drink from a cup • Take your baby to the clinic every month Assessment of the consumer’s comprehension, interpretation of the proposed guidelines, and ability to apply them, was considered essential before the PFBDGs could be finalised, disseminated to the consumer, and implemented as an educational tool for health professionals and community workers. This study was also the first in which PFBDGs were tested, and was intended to be a pilot study for further testing of PFBDGs for this age category in other parts of the country, adapted for different circumstances. The investigation was conducted among women who were mothers or caregivers to infants 6-12 months of age in the Afrikaans-, English- and Xhosa-speaking communities of the greater Oudtshoorn area, including Bongulethu, Bridgeton and Toekomsrus and its adjacent rural areas of Dysselsdorp, Calitzdorp, Uniondale, Ladismith and Zoar. Methodology The study was designed to be an observational, descriptive and cross-sectional study. Qualitative data was collected from a sample of 64 volunteers who took part in ten focus group discussions each attended by between 3 and 11 participants. Group discussions were recorded on videotape and quantitative and qualitative questionnaires measured pre-discussion knowledge and comprehension of guidelines, perceived hindrances to compliance with guidelines and perceived importance of guidelines as well as socio-demographic data. Results and conclusions With this study, useful and enlightening information was obtained which met the research objectives. Participants discussed the guidelines in depth and information obtained from the questionnaires were found to support what was said during the discussions. Body language or non-verbal communication as observed, and recorded on videotape, also complemented the information gained from the discussions. Summarily it can be said that the guidelines were well-received and perceived as important by the majority of respondents, although some of the guidelines were initially not well-understood without explanation. Furthermore, the fact that the applicability of the guideline on prolonged breast feeding seems to be the most problematic, is a cause for concern. In view of the results obtained in this study, it can be concluded that PFBDGs will have to be supported by extensive and appropriate educational material to be effective when introduced to the public. The findings of this study will be submitted to the PFBDG Working group for consideration before finalisation of the guidelines for the age group 6-12 months.
AFRIKAANSE OPSOMMING: Doelwitte en omvang van die studie Na aanleiding van die 1996 aanbevelings van ‘n VLO/WGO paneel van kenners vir die ontwikkeling van voedselgebaseerde dieetriglyne (VGDR) wat uniek en spesifiek gerig is tot die behoeftes van die bevolkings van verskillende lande, is ‘n Suid-Afrikaanse VGDR Werkgroep gevorm en uiteindelik ook ‘n Pediatriese VGDR (PVGDR) Werkgroep met die opdrag van laasgenoemde om VGDRe te ontwikkel vir kinders jonger as 7 jaar. ‘n Stel voorlopige Pediatriese VGDRe, gekies om die mees dringende pediatriese publieke gesondheidsvraagstukke, naamlik proteïn-energie wanvoeding, mikronutriënttekorte en infektiewe siektetoestande aan te spreek, is geformuleer vir elke ouderdomsgroep subkategorie (0-6 maande, 6-12 maande en 1-7 jaar). Die volgende stel voorlopige PVGDRe vir die ouderdomsgroep 6-12 maande is deur die Werkgroep goedgekeur om aan verbruikerstoetsing te onderwerp: • Geniet tyd saam met jou baba • Begin vanaf ses maande om jou baba klein hoeveelhede vaste kos te gee • Vermeerder jou baba se maaltye geleidelik na vyf keer per dag • Hou aan om jou baba te borsvoed • Bied gereeld vir jou baba skoon, veilige drinkwater aan • Leer jou baba om uit ‘n koppie te drink • Neem jou baba elke maand kliniek toe Evaluering van die verbruiker se begrip, interpretasie van die riglyne en die vermoë om die riglyne te implementeer, is as noodsaaklik beskou voordat die PVGDRe gefinaliseer kon word, vrygestel kon word aan die publiek, en aan professionele- en gemeenskapsgesondheidswerkers beskikbaar gestel kon word as ‘n onderrighulpmiddel. Hierdie studie was die eerste waarin PVGDRe getoets is en dit is bedoel as ‘n voorloperstudie vir verdere toetsing van PVGDRe vir hierdie ouderdomskategorie in ander dele van die land en aangepas vir ander omstandighede. Die ondersoek is gedoen onder vroue wat moeders of versorgers van babas van 6-12 maande was in die Afrikaans- Engels- en Xhosasprekende gemeenskappe van die groter Oudtshoorn area wat Bongulethu, Bridgton en Toekomsrus insluit asook die nabygeleë plattelandse gemeenskappe van Dysselsdorp, Calitzdorp, Uniondale, Ladismith en Zoar. Metodiek Die studie is ontwerp om ‘n waarnemende en beskrywende analise van ‘n deursnee van die studiepopulasie moontlik te maak. Kwalitatiewe data is verkry van ‘n proefmonster van 64 vrywilligers wat deelgeneem het aan tien fokusgroep besprekings wat elk deur 3 tot 11 persone bygewoon is. Groepbesprekings is op videoband opgeneem en kwantitatiewe en kwalitatiewe vraelyste het voorbesprekings kennis en begrip van die voorgestelde riglyne, vermeende verhindering tot uitvoering van die riglyne en vermeende belangrikheid van riglyne sowel as sosio-demografiese inligting gemeet. Resultate en gevolgtrekkings Met hierdie studie is bruikbare en verhelderende inligting verkry wat beantwoord het aan die doelwitte van die studie. Deelnemers het die riglyne in diepte bespreek en dit is bevind dat inligting wat van die vraelyste verkry is, ook dit bevestig het wat gedurende die sessies bespreek is. Lyftaal en nie-verbale kommunikasie soos waargeneem en soos op videoband vasgelê, het ook die inligting ondersteun wat van die besprekingsessies verkry is. Opsommend kan gesê word dat die riglyne goed ontvang is en as belangrik beskou is deur die meerderheid van respondente. Sommige van die riglyne was nie vir deelnemers goed verstaanbaar sonder meegaande verduideliking nie. Verder is die feit dat die toepasbaarheid van die riglyn met betrekking tot ‘n verlengde tydperk van borsvoeding voorgekom het as die mees problematiese, ‘n rede tot kommer In die lig van die resultate van hierdie studie, kan daar tot die slotsom gekom word dat PVGDRE ondersteun sal moet word deur omvattende en gepaste onderrigmateriaal om effektief te kan wees wanneer dit aan die publiek bekend bekend gestel word. Die bevindings van hierdie studie sal aan die Pediatriese VGDR Werkgroep voorgelê word vir oorweging voordat riglyne vir die ouderdomsgroep 6-12 maande gefinaliseer word.

Full textAbstract:
The aim of this study was to investigate the cadmium (Cd) exposure level from traditional food in Fort Resolution, Northwest Territories. Cd concentration in the liver and kidney of caribou and moose exceeded the action level (1 $ mu$g/g) established by Agriculture Canada, but the frequencies of consumption of these foods were relatively low. Cd intakes from traditional food ranged from 0.01 to 1713 $ mu$g/day/person. Average Cd intakes from traditional food were estimated to be 10% and 6% of the Provisional Tolerable Weekly Intake (PTWI), 7 $ mu$g/kg body weight/person, for women and men, respectively. The major contributors to the total Cd intake on a population basis were moose liver for women, and flesh of moose and caribou for men. The average Cd inhaled from cigarette smoking was 21.1 $ pm$ 9.1 $ mu$g/day/person. Total Cd intakes from traditional food and smoking were estimated to be 24% and 20% of the PTWI for women and men, respectively. The total Cd intakes of smokers and nonsmokers were significantly different (p $<$ 0.001). The total Cd intake via market and traditional food, and cigarette smoking was 246.4 $ mu$g/week which was lower than the PTWI, 500 $ mu$g/week. Another objective of this study was to investigate an effect of food preparation on Cd speciation in food. (Abstract shortened by UMI.)

Full textAbstract:
X-ray flourescence (XRF) and atomic absorption spectrophotometry (AAS) measurements for manganese, iron, copper, and zinc were compared for 96 samples of 21 foods from different sources. Correlation coefficients were 0.94 for manganese, 0.99 for iron, 0.93 for copper, and 0.91 for zinc for XRF vs. AAS determinations.
Similiar comparisons were performed on 228 samples of fast foods purchased in Utah retail outlets. Correlation coefficients ranged from 0.91 for copper to 0.97 for iron and zinc. Comparisons of values generated by XRF for manganese, iron, copper, zinc, selenium, arsenic, and aluminum to values certified by the National Bureau of Standards indicated no significant differences by student's t tests.
The simultaneous multielement capabilities of XRF allowed for an extensive screening study for high levels of toxic minerals in the fast foods. Levels of selenium, arsenic, and aluminum in fast foods were determined by XRF. Inductively coupled plasma was used to screen for high cadmium levels since cadmium detection limits by XRF were too high to be of value.

Full textAbstract:
Purpose: Vending machines are a component of the food environment that influences dietary choices. Previous vending machine studies have focused on schools and work sites. The purpose of this study was to utilize the Nutrition Environment Measurements Survey-Vending (NEMS-V) online tool to evaluate and rank the nutritional value of the vending environment of a large urban university.
Methods: A sample size of 40 vending machines at Georgia State University (GSU) was chosen. A list of products in each machine was recorded and given either a red, yellow or green ranking based on their nutrient content. Finally, the NEMS-V online tool was used to generate a report card for each individual machine and for the entire university.
Results: No vending machines were given either the Gold (greater than 50% items ranked green or yellow) or Silver (greater than 40% items ranked green or yellow) ranking. Five machines were given the Bronze level ranking, which meant the machines contained at least 30% yellow or green items. The remaining 35 machines contained less than 30% green or yellow items and were therefore not able to be awarded a ranking. Out of the 40 total machines sampled, less than 30% of them could be ranked and therefore the university could not be given an overall award. Conclusions: The poor nutritional quality of the vending environment at Georgia State University indicates a need for change. Improving the number of vending items from red to yellow or green will offer more variety and more nutritious choices for students.

Full textAbstract:
In the global industrial agricultural system many people lack access to high-quality nutritious foods and food production techniques are often inefficient and reliant on harsh chemical inputs. While numerous strategies exist to address the disparities present in the global food system, increasingly researchers and practitioners are looking to local food systems for solutions to strengthen community food security (CFS). CFS emphasizes small-scale production strategies such as farmer's markets, community gardens, and consumer supported agriculture. As these efforts evolve, research is needed to understand how these strategies affect communities. To explore a local CFS initiative, qualitative data were collected from community garden participants in Fellsmere, Florida, contextualized by participant observation. Interviews (N=9) focused on household and community nutritional concerns and the impacts of community gardening on diet quality and food security. Further, quantitative data were collected on the Fellsmere food environment using the USDA Thrifty Food Plan in six local food stores. Individual and household food security, the ability to obtain enough food to live a healthy life, was assessed using a food access and security survey (N=30). Results suggest that the Fellsmere food environment is lacking in the high-quality foods that participants' desire. Additionally, interview data suggests that participants want more control over their food production systems. This thesis provides a case study for better understanding what factors affect community members' perceptions of community food security.

Full textAbstract:
Suboptimal growth and nutritional status are problematic for children with cystic fibrosis (CF). Optimal nutrition predicts better lung function and longevity. Daily nutrition therapy for children with CF requires adequate food resources, knowledge of appropriate nutrition and behavior management skills, and confidence in one's ability to correctly apply the necessary skills. The Mountain West Cystic Fibrosis Consortium Questionnaire (MWCFC-Q) was designed as an educational needs assessment for parents of children with CF. The goal was to identify areas of concern that could be targeted for educational intervention to ultimately improve children's growth and nutritional status.
Data analyzed from 305 returned surveys included household food security, use of food assistance programs, knowledge of nutrition and general CF therapy, and self-confidence in ability to manage CF care. Questions regarding food security and knowledge of CF nutrition and general therapies were multiple choice. A ten point Likert-type scale was employed for determining confidence around management of CF related issues.
Respondents' median accuracy for questions regarding nutrient content of commonly used foods was 71.4% and 57.9% for CF nutrition therapy, respectively. Although overall confidence in CF management was high, scores for confidence in nutrition and behavioral management were significantly lower than for confidence in CF respiratory/medical management and CF Center recommendations.
In the second phase of this project, a pilot study using the chronic care model was developed for enhancement of nutrition and behavior management skills of parents of children with CF. Participants attended a series of four classes, each with a short didactic presentation, group activity, and discussion. Important features of this evidence-based educational program included nutrition and behavior management, self-efficacy, problem solving skills, and peer mentoring. A pre-, post-, follow-up, follow-up format was used to evaluate changes in participants' knowledge and self-confidence regarding nutrition and behavioral management. Comparisons were made with responses to the mailed survey using the same questionnaire. Secondary outcomes were changes in the rate of weight gain and growth for participants' children with CF. Participants showed statistically significant improvement in knowledge of nutrition therapy for CF at post-intervention compared with respondents to the mailed survey.

Full textAbstract:
Despite surf lifesavers being national icons of good health and good nutrition, surprisingly little factual information is known about the nutritional status of this unique aquatic fellowship. The purpose of this study was to investigate the nutritional intake and nutritional knowledge of three distinct groups of Australian surf lifesavers. Weighed food diaries are commonly used to assess the nutritional intake of athletes but this method has the disadvantage of a heavy respondent burden. Individuals being investigated must be literate and highly motivated to keep accurate records of food and drinks consumed. Food frequency questionnaires (FFQ) offer an alternative assessment method to weighed food records as they are relatively quick and easy to complete and do not require a high level of literacy. A secondary purpose of this study was to compare seven-day weighed food diaries with a FFQ that had already been validated for use with an older mixed gender population. The nutrient intakes of 60 members of Surf Lifesaving Australia were measured. Nineteen, who were professional lifeguards completed a FFQ. Thirty lifesavers and 11 surf ironmen each completed the FFQ, a seven-day weighed food diary and a nutritional knowledge questionnaire consisting of 15 multiple choice questions. There were significant differences between the three groups in age and activity with ironmen being significantly younger (mean age 22.9yrs) and significantly more physically active (mean 134mins/day) than either lifesavers (mean age, 31.3yrs, mean activity 46min/day) or lifeguards (mean age 35.8yrs, mean activity 65min/day). There were no significant differences in these parameters between lifesavers and lifeguards. The seven-day food diary revealed significant differences in nutrient intake between lifesavers and ironmen. Lifesavers consumed 1 1,807kJ, 125g protein (1.6g/kg) and 327g carbohydrate (4.Og/kg) while ironmen consumed 14,69/kJ, 1519 protein (1.9g/kg) and 4629 carbohydrate (5.6g/kg). Lifesavers and ironmen exceeded the RDIs for all vitamins and minerals measured. The seven day food diary demonstrated significant differences between the lifesavers and ironmen in energy, protein, fat, carbohydrate, alcohol, thiamin, niacin, calcium and iron. When the nutrient analysis data set for the FFQ was checked this method of dietary assessment was found to be unreliable as greater than 20 per cent of subjects were identified as being under-reporters. Lifesavers and ironmen both had good scores on the nutritional knowledge questionnaire and were able to identify groups of foods as being rich sources of fat, fibre, protein and iron. Ironmen were better able to answer questions specifically related to sport nutrition. All three groups meet the current recommendations for daily physical activity. Lifesavers and ironmen meet the current recommendations for, protein, fibre, vitamin and mineral intake and consume alcohol at levels within the current health guidelines. Ironmen have the highest carbohydrate intake which meets the current general health recommendations but consume less than the current special recommendations of sport nutritionists while lifesavers consume only 44% of energy as carbohydrate. These results suggest that while the both lifesavers and ironmen consume a relatively healthy diet only the surf ironmen could possibly be considered nutritional icons.

Full textAbstract:
Achieving and maintaining maximal peak bone mass is critical to the prevention of osteoporosis. Adequate calcium intake during youth is a major aspect of proper bone mass development. Because of the importance of calcium, a food frequency questionnaire (FFQ) that estimates calcium intake of 10- to 18-year-old Asian, Hispanic, and white youth living in the western United States was developed. This new FFQ was shown to accurately and reliably estimate calcium intake of these youth. Accuracy among Hispanics, however, was low and requires further evaluation. A second study examined intake of calcium, milk, and non-milk beverages of Hispanic and non-Hispanic white children aged 10 to 11 years and 15 to 18 years living in Utah. Milk fat percentage and source of beverage procurement were considered. Studies assessing the intake of calcium, calcium-rich foods, and foods that may interfere with calcium intake of youth in the United States were reviewed.

Full textAbstract:
This thesis aims to understand how public health evidence can be used better to inform the development of food and agriculture policy. It sets out to achieve this by developing and applying two methods that have been advocated for use in evidence-based policy making: health impact assessment (IDA) of agriculture and food policy and calculation of the burden of disease attributable to nutritional risk factors. Neither of the methods had previously been used in this policy context. They were selected as they illustrate two extreme models of evidence-based public health. The first consists of research based, investigator-led analysis producing generalisable, quantitative estimates. The second involves a more contextual, participatory, inter-sectoral approach to collecting. analysing and applying a broader range of data. The methods have been developed and applied using the fruit and vegetable sector as a case study, with specific reference to policies in the Republic of Slovenia, a country that was, during the course of this work, acceding to the European Union and presented a unique political opportunity. This thesis explores how these different evidence-based public health approaches are likely to inform policy, in the light of what we already know about influences on policy making. This thesis finds the total worldwide mortality currently attributable to inadequate consumption of fruit and vegetables is. estimated to be up to 2.635 million deaths per year. Increasing individual fruit and vegetable consumption to up to 600 g per day (the baseline of choice) could reduce the total worldwide burden of disease by 1.8%, and the burden of disease in Slovenia by 2%. The greatest impact would be on reduction of ischaemic heart disease and ischaemic stroke. However, such descriptive epidemiology is an insufficient basis for policy formulation as the results say nothing about how interventions are likely to reduce a problem The results of the health impact assessment show that evidence demonstrating priorities for public health action will be different from the type of evidence required for planning, policy implementation or evaluation.

Full textAbstract:
La presente tesi inizia con un’analisi dell’aspetto nutrizionale degli alimenti. In particolare, è stato discusso il concetto di dieta equilibrata, con riferimento ai principi della “dieta mediterranea”.
Proprio da questo modello alimentare trae ispirazione la “ottimazione”, una tecnica sviluppata e utilizzata per programmare pasti conformi a specifici standard nutrizionali (15/30/55 tra proteine, lipidi e carboidrati sull’apporto energetico totale, proporzioni tipicamente mediterranee).
Tali preparazioni alimentari sono state testate anche attraverso metodi di analisi sensoriale.
Il passaggio successivo è stato l’estensione del concetto di “ottimizzazione nutrizionale” a quello di “ottimizzazione ambientale”, dovuto all’ipotizzato minor impatto ambientale della dieta mediterranea.
Il LCA (Life Cycle Assessment) è la tecnica che è stata utilizzata per valutare l’impatto ambientale di alcuni prodotti alimentari, quali verdure surgelate, un salume e un formaggio.
Un ulteriore passaggio è stata la creazione di uno strumento di comunicazione, una nuova etichetta ambientale, realizzata per essere utilizzata dalle aziende per comunicare le loro performance ambientali e quindi il loro impegno al miglioramento continuo, e dai consumatori per ottenere maggiori informazioni sull’impatto ambientale dei prodotti acquistati quotidianamente, al fine di accrescere il proprio senso critico ed effettuare acquisti consapevoli.The thesis begins with an analysis of the nutritional aspects of foods. In particular, the concept of balanced diet has been discussed, by referring to the principles of "mediterranean diet". Just from this food model, the “optimation” draws inspiration, a technique developed and used to plan meals consistent with specific nutritional standards (15/30/55 between protein, fat and carbohydrate on the total energy intake, typically Mediterranean). These food preparations have been tested through sensory analysis methods. The next step is the extension of "nutritional optimization" concept to the "environmental optimization” one, owing to the presumed lower environmental impact of the Mediterranean diet. LCA (Life Cycle Assessment) is the technique used to assess the environmental impact of various food products, such as frozen vegetables, cured meats, dairy products. A further step is the creation of a communication tool, a new environmental label, designed to be used by companies to communicate their environmental performance and therefore their commitment to continuous improvement, and by consumers to obtain more information on the environmental impact of the foods daily consumed, in order to increase their critical sense and make purchases in a conscious way.

L’objectif de cette thèse était de développer un cadre conceptuel et méthodologique permettant d’évaluer l’impact global de l’alimentation sur la santé des consommateurs, en prenant en compte les dimensions microbiologiques, chimiques et nutritionnelles. Cette méthodologie a été développée à l’aide d’un cas d’étude portant sur l’alimentation des nourrissons (lait maternel et formules infantiles), incluant les facteurs suivants : C. sakazakii, Cryptosporidium, arsenic, polychlorobiphényles de type dioxine et acide docosahexaénoïque. Cinq modèles mathématiques probabilistes ont été développés pour quantifier les risques / bénéfices associés à chaque facteur. Ils ont été ensuite harmonisés, quand cela a été possible, à l’aide d’un indicateur commun de santé publique, le DALY. Les résultats ont été obtenus par simulation de Monte Carlo de second ordre afin de quantifier séparément l’incertitude et la variabilité. Les techniques probabilistes ont permis de prendre en compte d’une part la variabilité inhérente à la biologie (hétérogénéité entre individus d’une même population) et d’autre part l’incertitude liée au manque de connaissances et de données. De plus, la séparation de la variabilité et de l’incertitude a consolidé l’évaluation, permettant une interprétation plus cohérente des résultats et donc fournissant des informations plus complètes aux décisionnaires. La méthode mise en oeuvre dans ce travail de thèse pourra servir de base pour d’autres cas d’études et pourra aussi être utilisée pour continuer le développement méthodologique de l’évaluation risque-bénéfice. Cette démarche s’inscrit dans une approche plus générale d’analyse multi-critères des systèmes agronomiques et alimentairesThe objective of the present PhD project was to develop a conceptual and methodological framework to assess the overall impact of food consumed on human health, including microbiological, chemical and nutritional dimensions. This methodology was developed using a case study on infant milk-based diet (breast milk and infant formulas) taking into account the following selected factors: C. sakazakii, Cryptosporidium, arsenic, dioxin like polychlorinated biphenyls and docosahexaenoic acid. Five probabilistics mathematicals models were developed to quantify risks / benefits associated with these factors. When possible, they were harmonized using a common public health indicator, the DALY. Results were obtained by second-order Monte Carlo simulations in order to quantify separately the uncertainty and the variability. Probabilistic techniques enabled to take into account on the one hand the biology related to variability (heterogeneity between individuals of the same population) and on the other hand the uncertainty linked to the lack of knowledge and data. In addition, separation of variability and uncertainty strengthened the evaluation by enabling a more accurated interpretation of results and by providing more comprehensive information for policy makers. The method used in this PhD thesis can be considered as a robust basis for other case studies and can be also used to continue methodological development in risk-benefit assessment. This approach is also part of a broader area: the multi-criteria decision analysis of agronomic and food systems

Multiple sclerosis (MS) is a neurodegenerative disease of uncertain etiology and pathology, affected by genetic and environmental factors. Nutrition may be one of these factors. This study used one validated 80-item food frequency questionnaire and one 24-hour recall to assess dietary intake, anthropometric and lifestyle practices, and self-perceived impacts of food in 36 adults with MS. Although only 3 persons followed special diets for MS, 28 indicated food influenced the way they felt, and 17 thought food directly impacted their MS. Over 50% of participants were identified as potential underreporters of energy. Low intakes in grains, dairy, and fruits and vegetables were commonly observed. The FFQ and 24-hour recalls estimated different mean sample intakes of all nutrients; these differences were significant for carbohydrates, water, iron, magnesium, riboflavin, niacin, and omega-3. Both tools identified mean intakes below suggested AI levels for fibre, calcium, vitamin D, omega-3 and omega-6, and above the UL for sodium. Supplements were used by 72% of participants, and increased estimated nutrient intakes above the EAR or the UL for some nutrients in some individuals.

Thesis (MNutr--Stellenbosch University, 2015.ENGLISH ABSTRACT: Introduction Malnutrition, in both adults and children, is a problem worldwide with negative health consequences. The World Health Organization (WHO) and Food and Agricultural Organization (FAO) of the United Nations (UN) therefore initiated the implementation of country-specific food-based dietary guidelines (FBDGs) to be used as an educational tool to address nutrition-related health issues. They further suggested consumer testing to evaluate the comprehension and cultural acceptability thereof prior to the release of country-specific FBDGs. Focus group discussions (FGDs) were recommended for consumer testing. Aim The aim of this study was to assess the comprehension and applicability of the 2007 version of the preliminary South African paediatric food-based dietary guidelines (PFBDGs) for healthy infants aged 6–12 months in Soshanguve and Ga-Rankuwa. Specific objectives included qualitative evaluation of exposure to preliminary PFBDGs, participants’ interpretation thereof, cultural acceptability and practical application of the guidelines. Socio-demographic information was collected to determine whether these factors could potentially exert an influence on the comprehension and applicability of the FBDGs. This study could further inform emerging efforts to update public health initiatives to educate mothers/caregivers of infants. Methodology An observational, cross-sectional study design was followed, incorporating both qualitative and quantitative research methods. FGDs were utilised to assess comprehension of the PFBDGs and gather insight into perceptions, attitudes and appropriateness of the PFBDGs. Quantitative data were collected by means of a questionnaire regarding the socio-demographic profiles of participants. Setting This study focused on two small, densely populated towns, Soshanguve and Ga-Rankuwa, in the north western district of Tshwane in the Gauteng province of South Africa. The areas represent relatively low socio-economic communities that include a mix of formal and informal urban setting. Participants Twenty-seven Northern Sotho-speaking mothers and caregivers of infants aged 6–12 months participated in a total of six FGDs. Each FGD was attended by between three and six participants. Results None of the participants had previous exposure to the PFBDGs, although they were familiar with most of the concepts. Guidelines were generally well received and understood, but a few were misinterpreted; particularly those pertaining to “enjoy time with your baby”, “increase your baby’s meals to five times per day” and “teach your baby to drink from a cup”. These needed further explanation and rephrasing by the investigator to improve their comprehensibility. The guideline pertaining to breastfeeding was the most familiar, well accepted and most generally applied. Quantitative results indicated no significant difference between the socio-demographic profiles of participants in Soshanguve and Ga-Rankuwa. Participants’ education level, employment status and housing conditions were considered a good representation of the population. It appears that socio-demographic circumstances may affect exposure to, and interpretation and application of the PFBDGs. Conclusion Many of the adjustments recommended from this research is consistent with the changes incorporated in the recently published revised PFBDGs. Supportive documentation, educational material and health campaigns tailored to specific socio-demographic groups may further enhance the interpretation of the revised guidelines and their exposure to the public, once tested and adopted.
AFRIKAANSE OPSOMMING: Inleiding Wanvoeding onder kinders en volwassenes, is ʼn wêreldwye probleem wat, as dit nie aangespreek word nie, ernstige gesondheidsgevolge kan inhou. Die Wêreldgesondheidsorganisasie (WGO) en die Voedsel-en-landbou-organisasie (VLO) het die implementering van voedselgebaseerde dieetriglyne (VGDR) spesifiek aan elke land geïnisieer sodat dit as opleidingshulpmiddel kan dien om voedselverwante gesondheidsprobleme op te los. Daar is voorgestel dat verbruikers die riglyne in fokusgroepbesprekings (FGBs) evalueer om begrip en die kulturele toepaslikheid van bevolking-spesifieke riglyne te toets voordat dit bekendgestel word. Doel Die doel van die studie was om begrip en die toepassing van die 2007 weergawe van die voorlopige Suid-Afrikaanse pediatriese voedselgebaseerde dieetriglyne (PVGDR) vir gesonde kinders van 6–12 maande te bepaal. Spesifieke doelwitte het kwalitatiewe evaluering ten opsigte van blootstelling, deelnemers se interpretasie, kulturele aanvaarbaarheid en praktiese toepassing van die riglyne ingesluit. Sosiodemografiese inligting is ingesamel om te bepaal of daar ʼn verband bestaan tussen hierdie omstandighede en die begrip en toepassing van PVGDR’s. Hierdie studie kan toekomstige pogings ondersteun om openbare-gesondheidsprogramme by te werk en om moeders en versorgers oor babas in te lig. Ontwerp Die studieontwerp was ’n waarnemende deursnit met kwalitatiewe en kwantitatiewe navorsingsmetodes. FGBs was gebruik om die begrip van die PVGDR’s te bepaal en insigte oor die persepsies, houdings en geskiktheid van die PVGDR’s in te samel. Kwantitatiewe data is ingesamel met ʼn vraelys oor die sosiodemografiese profiele van deelnemers. Omgewing Die studie het gefokus op twee klein, digbevolkte stedelike gebiede, Soshanguve en Ga-Rankuwa in Tshwane, die noord-westelike distrik van die provinsie Gauteng in Suid-Afrika. Die areas verteenwoordig relatief lae sosio-ekonomiese gemeenskappe met ʼn mengsel van formele en informele stedelike nedersettings. Deelnemers Die studiegroep het 27 Noord-Sotho-sprekende moeders en versorgers ingesluit wat aan altesaam 6 FGB’s deelgeneem het. Tussen drie en ses deelnemers het elke FGB bygewoon. Resultate Geen deelnemers was voorheen aan PVGDR’s blootgestel nie, hoewel die meerderheid met meeste van die begrippe bekend was. Die riglyne was oor die algemeen goed aanvaar en verstaanbaar, maar ʼn paar was verkeerd geïnterpreteer; veral “geniet tyd saam met jou baba”, “vermeerder jou baba se maaltye na vyf kere per dag” en “leer jou baba om uit ʼn koppie te drink”. Verduideliking en herformulering was nodig om begrip te verbeter. Die riglyne oor borsvoeding was die bekendste, was die beste aanvaar en was in die algemeen toegepas. Kwantitatiewe resultate het aangedui dat die sosiodemografiese profiel van deelnemers uit Soshanguve en dié uit Ga-Rankuwa nie beduidend verskil nie. Deelnemers se opleidingsvlak, werkloosheidstatus en huislike omstandighede het die populasie goed verteenwoordig. Daar is bevind dat sosiodemografiese omstandighede blootstelling aan en begrip en toepassing van PVGDR’s kan beïnvloed. Gevolgtrekking Baie van die wysigings wat voorgestel is deur hierdie studie, stem ooreen met die verandering wat aangebring is in die onlangs gepubliseerde hersiene PVGDR’s. Ondersteunende dokumente, opvoedkundige materiaal en gesondheidsveldtogte vir spesifieke sosiodemografiese groepe sal die korrekte interpretasie van riglyne asook openbare bewusmaking bevorder. Die riglyne kan, met minimale aanpassings, suksesvol as ʼn voedingsverwante opvoedkundige hulpmiddel in die gemeenskap gebruik word. Baie van hierdie aanpassings is reeds aangebring tydens die ontwikkeling van die veranderde PVGDR’s. Die bevindinge van die studie kan ʼn kernbydrae tot die voorstelle lewer, en aanduidings vir voorstelle vir verdere ontwikkeling en evaluering oplewer.

Resumo: O Programa Bolsa Família (PBF) instituído em 2001 no Brasil é o único programa de âmbito nacional para o enfrentamento das questões relacionadas ao estado nutricional das crianças. Embora venha se expandindo ano após ano, ainda são poucas as avaliações no que se refere à repercussão nas condições de saúde e nutrição da população. O objetivo deste estudo é verificar o impacto do PBF no estado nutricional das crianças beneficiárias. Método: Inicialmente foi realizado um estudo de revisão sistemática com o objetivo de obter informações do estado nutricional dos beneficiários. Na sequência por meio de levantamento de dados secundários do Sistema de Vigilância Alimentar e Nutricional (SISVAN) de Blumenau-SC foi realizado um estudo de coorte longitudinal, comparando a evolução do estado nutricional das crianças beneficiárias e não beneficiárias do Programa Bolsa Família, durante os anos de 2006 a 2008. Resultado: Em ambos os trabalhos pode-se verificar que os dados não permitem concluir se o PBF modificou ou não o estado nutricional dos beneficiários
Abstract: The ¨Bolsa Família¨ Program (PBF) established in 2001 is the only nationwide program for dealing with issues related to food and nutrition. Although it will be expanding, there are few reviews regarding the impacts on health and nutrition. The objective of this study is to assess the impact of PBF on nutritional status of children beneficiaries. Method: Initially was made a systematic review study in order to obtain information of the nutritional status of the beneficiaries. Following through secondary survey data of system for food and nutritional surveillance (SISVAN) of Blumenau-SC was conducted a longitudinal cohort study, comparing the evolution of the nutritional status of children beneficiaries and non-beneficiaries of ¨Bolsa Família¨, during the years 2006 and 2008. Results: both studies don't allow to conclude that the PBF changed or not the nutritional status of the beneficiaries

Full textAbstract:
Background: With the increasing variety of snack foods containing probiotics infiltrating the market, it is important that consumers become more aware and knowledgeable about these products. Purpose: The aim of this study was to investigate consumer behaviors by assessing frequently consumed snacks, knowledge about probiotics, and awareness of snack foods containing probiotics among students across various disciplines within a university setting. Methods: There were 125 college students (n = 34 male, n = 91 female) recruited, all 18 years and older, and evaluated via a 19-item questionnaire using descriptive statistics, one-way analysis of variance (ANOVA) and Gabriel’s post hoc test. Level of significance was set at p ≤ 0.05. Results: There was a statistically significant difference in knowledge about probiotics among the colleges, p = 0.012. Specifically, students in the College of Health and Human Services (CHHS) were statistically significantly more knowledgeable than those in the Science, Technology, Engineering and Mathematics (STEM) college, p = 0.010. There was no statistically significant difference in awareness of snack foods containing probiotics, p = 0.262. On average, participant’s knowledge about probiotics was low (48.1%) and awareness of snack foods containing probiotics was very low (2.5%), though, a majority of participants (94.1%) were aware that yogurt contained probiotics. Conclusion: Overall, these findings should guide food product developers and marketers to create products that are relevant and messages that enhance consumer’s knowledge and awareness to the existence of the probiotics in that product.

Food insecurity is a important risk factor that can influence the physical development of children, but can also be a stressor of family relationships. The objective this cohort study was conduct due to evaluate the effect of food insecurity on maternal and child health. 222 mothers (19 to 35 yo) and their new born were follow up. The first interview occurred in the hospital and the second, after two months, in home. A face to face questionnaire was applied. Questions about delivery, child and mother health, food consumption, familiar food security status were included and the mother and child nutritional status were evaluated. 59% of mothers were in food insecurity situation. 15,8% in moderate and severe food security situation. Each one of these groups were compared with the others mothers. The increase of mothers over weight prevalence was observed after the gestational period. Food secure mothers had higher weight gain and the consumption of non-healthy food was high and no difference was observed between food insecure or food secure mothers, but these ones declared consumption more fruits, vegetables and crude salads.
A insegurança alimentar é um importante fator de risco que pode influenciar o desenvolvimento físico das crianças, como também pode ser um estressor das relações familiares, diante disto, o objetivo foi avaliar os efeitos da insegurança alimentar na saúde materno-infantil. Estudo de coorte iniciado em duas maternidades públicas em João Pessoa. Foram acompanhadas 222 parturientes, de 19 a 35 anos de idade e seus filhos. Realizou-se entrevista na maternidade para coletar informações sobre o pré-natal e parto e no domicilio após o segundo mês de vida do RN, onde aplicou-se um questionário sobre saúde e situação de insegurança alimentar, além da avaliação do estado nutricional. 59,0% das mães encontravam-se em insegurança alimentar, sendo 15,8% moderada ou grave, sendo estes os dois critérios de definição dos grupos de exposição avaliados. Observou-se aumento da prevalência de excesso de peso após a gestação sendo que o ganho de peso gestacional foi maior entre as mães em famílias em situação de segurança alimentar. O consumo alimentar de alimentos não saudáveis foi igual nos dois grupos sendo que as mães em segurança alimentar declararam consumir mais frutas, legumes e saladas cruas que as demais.

Aquesta tesi examina els determinants sociodemogràfics i d'estil de vida del consum d’aliments funcionals i el consum de begudes entre els adults i adolescents de la població de les Illes Balears. La població adulta preferí consumir aliments funcionals com llet baixa en greix, el cafè i el té, probiòtics i els cereals per a l’esmorzar. De la mateixa manera, la població adolescent també preferí consumir llet modificada (baixa en greixos o llet enriquida en omega-3), probiòtics i els cereals per a l’esmorzar. El consum de molts aliments funcionals s’associà positivament amb la ingesta de certs components funcionals.
L’aigua és la principal font de fluid en la població adolescent i adulta. Mentre que una major proporció de la població adulta consumí begudes com la llet baixa en greix, el cafè i el té, la majoria dels adolescents preferiren consumir begudes com el suc de fruita natural o la llet sencera. La ingesta de begudes contribueix d’un 6 a un 13% de la ingesta energètica diària total (TEI) en adolescents, mentre que en els adults el consumo de begudes proporciona del 9 al 18% de la TEI diària.La presente tesis fue estudiar los determinantes socio-demográficos y de estilo de vida del consumo de alimentos funcionales i consumo de bebidas entre los adultos y adolescentes de la población de las Islas Baleares.

The present thesis examined the socio-demographic and lifestyle determinants of the functional food (FF) and beverage consumption among adult and adolescent population in the Balearic Islands. Adult population preferred to consume FFs like low-fat milk, coffee and tea, probiotics and breakfast cereals. Similarly, adolescent population also preferred to consume modified milk (low-fat or omega-3 enriched milk), probiotics and breakfast cereals. Consumption of many FFs was positively associated with the intake of several functional components. Water was found the main fluid source in adolescent and adult population. While a higher proportion of adult population consumed beverages like low-fat milk, coffee and tea, the majority of adolescents were preferred to consume beverages like natural fruit juice or whole fat milk. Beverage intake contributed 6 to 13% of the daily total energy intake (TEI) of adolescents, while in adults beverage consumption provided 9 to 18% of the daily TEI.

Thesis (MSc Nutrition Science)--Stellenbosch University, 2004.ENGLISH ABSTRACT: Probiotics (live microbes) and prebiotics (non-digestible food-ingredients) are rapidly gaining interest worldwide as supplements and functional food ingredients but little South African information in this regard is available. Furthermore, the availability of South African produced probiotic concentrates for commercial use is also very limited. The aims of this study therefore were to complete a market and product assessment of probiotic and prebiotic containing products in South Africa and to evaluate probiotic strains for commercial use in South Africa. For the purposes of market and product assessment probiotic and/or prebiotic containing products manufactured in South Africa were identified. The scientific and legal correctness of health and content claims made on the labels of the products were assessed. An exploratory survey was conducted to determine the awareness of South African consumers of probiotics and prebiotics. For the evaluation of probiotic strains for potential commercial use in South Africa, a panel of twelve lactic acid bacteria (LAB) were screened for inhibitory activity against two porcine pathogens and indicator strains from the LMG-panel isolated from the faeces of patients diagnosed with AIDS. The five LAB with the best inhibitory activity were tested for growth in soymilk-base and for the effect of lyophilization on the inhibitory activity thereof. The effect of prebiotics on the growth and inhibitory activity of the strains was tested in vitro. A range of products containing probiotics and prebiotics available on the South African market was identified. Irregulatories concerning health claims on the labels were found, but content claims seemed to be less of a problem. The results also indicate that the proposed South African regulations for the labelling of probiotic and prebiotic containing products need to be revised to include the probiotic and prebiotic related health claims for which sufficient scientific evidence is available. The probiotic strains with potential for commercial use in South Africa that were identified, include Lactobacillus plantarum 423, Lactobacillus casei LHS, Lactobacillus salivarius 241, Lactobacillus curvatus DF38 and Pediococcus pentosaceus 34. These strains were grown successfully in soymilkbase and lyophilization did not have a negative effective on the inhibitory activity thereof. The growth and inhibitory activity of the five LAB were promoted when combined with 1% (w/v) Raftilose® Synergyl . It is concluded that although a variety of probiotic and prebiotic containing products are available on the South African market, the scientific and legislative correctness of especially health related claims is not satisfactory and that South African consumer awareness of these products is low. It is also concluded that a combination of at least three of the five identified LAB and 1% Raftilose® Synergy can be used by South African manufacturers for the production of probiotic and prebiotic containing supplements.
AFRIKAANSE OPSOMMING: Die belangstelling in probiotika (lewendige mikrobe) en prebiotika (onverteerbare voedselbestanddele) as supplemente en funksionele voedselbestanddele is besig om wêreldwyd toe te neem, alhoewel weinig Suid-Arikaanse inligting in hierdie verband beskikbaar is. Die beskikbaarheid van Suid-Afrikaans geproduseerde probiotika konsentrate vir kommersïele gebruik is ook baie beperk. Die doelwitte van hierdie studie was dus om 'n mark- en produkevaluering van probiotika- en prebiotika-bevattende produkte in Suid-Afrika uit te voer en om probiotiese stamme te evalueer vir uiteindelike kommersiële gebruik in Suid-Afrika. Vir die doel van die mark- en produkevaluering is probiotika- en prebiotika-bevattende produkte wat in Suid-Afrika vervaardig word geïdentifiseer. Die wetenskaplike en wetlike korrektheid van die gesondheids- en inhoudsaansprake op die etikette van die produkte is evalueer. 'n Markopname is uitgevoer om die bewustheid van Suid-Afrikaanse verbruikers van probiotika en prebiotika vas te stel. Vir die evaluering van probiotiese stamme vir potensïele kommersiële gebruik in Suid-Afrika is 'n paneel van twaalf melksuurbakteriëe getoets vir inhibitoriese aktiwiteit teen twee patogene geïsoleer uit varke asook teen indikator stamme van die LMG-paneel. Die vyf melksuurbakteriëe met die beste inhibitoriese aktiwiteit is getoets vir groei in sojamelk-basis en ook vir die effek van vriesdroging op die groei en inhibitoriese aktiwiteit van die stamme daarvan. Die effek van prebiotika op die groei en inhibitoriese aktiwiteit van die stamme is in vitro getoets. 'n Reeks van probiotika- en prebiotika-bevattende produkte wat beskikbaar is op die Suid-Afrikaanse mark, is geidentifiseer. Ongeruimdhede met die gesondheidsaansprake op die etikette is gevind, maar inhoudsaansprake was minder problematies. Die resultate dui ook daarop dat die voorgestelde Suid- Afrikaanse regulasies vir die etikettering van probiotika- en prebiotika-bevattende produkte hersien moet word om al die probiotika- en prebiotika-verwante gesondheidsaansprake waarvoor voldoende wetenskaplike bewyse beskikbaar is in te sluit. Die probiotiese stamme met potensiaal vir kommersiële gebruik in Suid-Afrika sluit die volgende in: Lactobacillus plantarum 423, Lactobacillus casei LHS, Lactobacillus salivarius 241, Lactobacillus curvatus DF 38 en Pediococcus pentosaceus 34. Hierdie stamme is suksesvol gekweek in sojamelk-basis en vriesdroging het nie' n negatiewe effek op die groei en inhibitoriese aktiwiteit daarvan gehad me. Die kombinasie van die vyf melksuurbakteriëe met 1% Raftilose® Synergy het die groei en inhibitoriese aktiwiteit daarvan bevorder. Die gevolgtrekking wat gemaak word is dat alhoewel 'n varrasie van probiotika- en prebiotikabevattende produkte beskikbaar is op die Suid-Afrikaanse mark, die wetenskaplike en wetlike korrektheid van spesifiek die gesondheids-verwante aansprake op die etikette daarvan nie bevredigend is nie en dat die bewustheid van die Suid-Afrikaanse verbruikers van hierdie produkte laag is. Die gevolgtrekking kan ook gemaak word dat 'n kombinasie van ten minste drie van die vyf geïdentifiseerde melksuurbakteriëe en 1% Raftilose® Synergy deur Suid-Afrikaanse vervaardigers gebruik kan word vir die vervaardiging van produkte wat probiotika en prebiotika bevat.

Friebert, Alyssa Marie. "Assessment of Maternal and Infant Outcomes of Moderately Malnourished Pregnant Adolescents in Malawi." DigitalCommons@CalPoly, 2018. https://digitalcommons.calpoly.edu/theses/1884.
Full textAbstract:
Background: Adolescent childbearing and maternal malnutrition are common in low- and middle-income countries and are associated with increased risk for poor maternal and infant outcomes. Adolescent pregnancy compounded with moderate malnutrition exacerbates outcomes common to both individually. Supplementary foods may be a way to improve outcomes in malnourished adolescent pregnant women.
Objective: To retrospectively assess maternal and infant outcomes in moderately malnourished pregnant young adolescents (16-17 YO), older adolescents (18-19 YO), and adults (≥20 YO) in response to one of three nutritional interventions and in a pooled treatment group analysis, and to assess differences in infant outcomes by infant gender.
Methods: Height, weight, MUAC, and FH were measured in pregnant women with MUAC >20.6 cm and < 23.0 cm at baseline (N=1828) every 2 weeks over the course of enrollment while receiving either: 1) macro- and micronutrient fortified, peanut-based, ready-to-use supplementary food (RUSF), 2) corn-soy blended flour with a prenatal multiple micronutrient supplement (CSB-UNIMMAP), or 3) corn-soy blended flour with iron and folic acid (CSB-IFA). Each provided approximately double the RDA of most micronutrients, 900 kcal/day and 33-36 g/day protein. Postpartum maternal and infant measurements were taken at delivery, and after 6 and 12 weeks. Maternal age at enrollment variable was transformed from a continuous variable into a categorical variable; young adolescent (16-17 YO), older adolescent (18-19 YO), and adults (≥20 YO). General linear models with normal errors were used to compare: 1. Adolescent maternal and infant outcomes by intervention, 2. Adolescent maternal and infant outcomes by maternal age within each intervention group, 3. Maternal and infant outcomes in a pooled treatment analysis by maternal age, 4. Interaction effects between maternal age and intervention, 5. Infant outcomes by infant gender. If differences between groups were detected, they were tested using the Tukey HSD test (response) or the likelihood ratio-based odds ratios (categorical). Odds ratios were measured using effects likelihood ratio tests via logistic regression. Response variables included in the analyses were BMI and fundal height at enrollment.
Results: There were 297 young adolescents, 582 older adolescents, and 949 adults enrolled. Adolescents enrolled in the study at a younger gestational age than the adult mothers. Upon enrollment, BMI was greater and FH was smaller in the adolescent mothers than adults. At delivery, adolescent mothers had gained less weight on treatment, delivered with a lower final MUAC and FH, had increased odds of delivering extremely prematurely, and the greatest odds for delivering before recovery from malnutrition (MUAC ≥23.0 cm). Infants of young adolescent mothers were inferior anthropometrically to infants of the older mothers and had greatest odds of being underweight and stunted through 12 weeks of age. Young adolescents had the greatest odds for delivering LBW infants compared to the adults. Catch up growth was observed in the infants of older adolescents by 12 weeks of age; however, no catch up was observed for the infants of young adolescents. No one intervention was more helpful than another in determining maternal and infant outcomes of the adolescent mothers, and male infants had greater odds of being underweight and stunted at 6 and 12 weeks of age.
Conclusions: Although adolescents did not appear to have characteristics of more severe clinical malnutrition, such as lower BMI, lower maternal height, and increased rates of HIV at baseline, maternal and infant outcomes were worse for the adolescent mothers compared to the older, more mature mothers. Adolescents gained less weight during pregnancy and delivered smaller infants that were unable to catch up linearly and with weight gain. Pregnant adolescents, particularly young adolescents, are a high-risk population and public health efforts should be made to delay the age of first pregnancy.

2013Child undernutrition is the outcome of numerous complex and interrelated factors. It is considered a worldwide health concern, also in Botswana. Undernourished infants are especially vulnerable to develop nutritional deficiencies and diseases. Tsabana was developed as a weaning food to improve the diet quality of undernourished infants in Botswana but also as a dietary intervention product for the four-month- to five-year-old age group to improve the nutritional status of Batswana children. The study undertook a theoretical nutritional appraisal of Tsabana and assessed its acceptance and use in rural districts of Botswana. A quantitative approach that incorporated a survey was used as the research design for the study. A pre-tested questionnaire consisting of close-ended questions in the multiple choice format was used to collect the data on the field acceptance and use of Tsabana. The questionnaire was completed by 105 caregivers of infants aged six to 36 months old visiting the selected clinics with the research sites the Ngamiland, North East, Central and Kweneng rural districts. The energy, macro- and micronutrient content adequacy of Tsabana was compared to the Codex Alimentarius Standard for Processed Cereal-based Foods for Infants and Young Children (Codex Standard 074) and the Proposed Nutrient Composition for Fortified Complementary Foods (PNCFCF). Sorghum and soya are the two major ingredients of Tsabana which contribute to its protein and energy provision. The nutrient appraisal revealed that the level of energy provided by Tsabana is more than the specified Codex Alimentarius Standard composition but slightly less than the PNCFCF specified range, whereas the protein level is within the specified ranges as put forward by both the Codex composition and the PNCFCF, respectively. The results further revealed that in comparison to the PNCFCF the content of vitamins A, E, C and pyridoxine, zinc, iodine and iron were less than the specified ranges. The content of vitamins A and D met the compositional guidelines of the Codex Alimentarius Standard. The micronutrient provision of Tsabana in relation to the World Health Organization (WHO) recommended nutrient intakes was mostly adequate except for pyridoxine which was inadequately provided for both seven- to 18-month-old (33% provision) and one- to three-year-old (52% provision) infants at the daily rations of 75 gram (g) and 200 g powder respectively. Some minerals also were provided at inadequate amounts, e.g. iodine at a daily provision of 42% as well as iron at 26% for seven- to 12-month-old and 12- to 18-month-old infants both provided at a daily ration of 75 g Tsabana powder. Zinc was only provided at 19% of the WHO recommended intake for seven- to 12-month-old and 14.8% for 12- to 18-month-old infants. As with the absence of omega-3 and omega-6 fatty acids, the minerals selenium and copper are not provided by Tsabana. The micronutrient fortification compounds used in Tsabana for the mineral and vitamin additions as vitamin A palmitate, cholecalciferol, vitamin E acetate, calcium pantothenate, carbonate and tri-calcium phosphate (ratio 1:18:482), zinc sulphate and potassium iodate are readily bioavailable, but not the vitamin A and vitamin E compounds used. The iron fortificant used is not stipulated on the Tsabana package. The field survey results revealed that Tsabana was well accepted by the infants as perceived by their caregivers as the majority indicated that Tsabana was enjoyed (80%) and that it tasted nice (71.4%). The majority (78.1%) of the caregivers also indicated that the wellbeing of the infants improved on receiving Tsabana. Most (51.4%) of them also knew that Tsabana is more nutritious than other cooked porridges. Tsabana though was not used properly as most of the caregivers fed Tsabana to the infant only once a day (60.9%) instead of two to three times (for infants six- to 18-month-olds) and did not use enough water (3½ cups) (76.2%) to cook one feeding of Tsabana as stipulated on the Tsabana package. The product use factors, which include the number of daily Tsabana feedings provided, the addition of sugar to the cooked Tsabana, the amount of water used to cook one feeding of Tsabana and the cooking period of one feeding were the factors significantly (p < 0.05) linked to the perceived infant acceptance of Tsabana. The number of daily Tsabana feedings was linked to the perceived enjoyment of Tsabana (p < 0.05) and its perceived texture (p < 0.05) and colour (p < 0.05) acceptance. While the addition of sugar to the cooked Tsabana was linked to its perceived enjoyment (p < 0.05), the amount of water used to its perceived taste acceptance (p < 0.05) and the cooking period of one feeding to its perceived colour acceptance (p < 0.05). For instance, more caregivers in relation to the enjoyment of Tsabana and its colour and texture acceptance who perceived it not to be enjoyed and not having a nice colour or texture, indicated not to feed it daily in comparison to caregivers who perceived that Tsabana was enjoyed by the infants and that it had a nice colour and texture. The caregiver perceived infant wellbeing improvement through the provision of Tsabana and the perceived difference between Tsabana and other cooked porridges were the only two clinic-related factors which significantly (p < 0.05) influenced the infant acceptance of Tsabana as perceived by the caregivers. For instance, while the majority (86.2%, 84.8% and 80%, respectively) of the caregivers who perceived the infant taste acceptance of Tsabana as very nice, nice or acceptable indicated that providing Tsabana to the infant improved the infant’s wellbeing, the majority (80%) who perceived it as not tasting nice indicated that providing Tsabana to the infant had not improved the infant’s wellbeing. More than half of the caregivers who perceived the infant texture acceptance of Tsabana as acceptable (59.4%) or nice (56.8%) indicated that Tsabana provides more nutrition to the infant. However, less than half (46.2%) of the caregivers who perceived the texture of Tsabana as not nice indicated that it provides more nutrition to the infant. The caregiver education level was the only demographic factor that significantly (p < 0.05) influenced the acceptance of Tsabana. The majority (90.3%) of the caregivers who attained a secondary education level (form 1 to form 4) and higher, perceived the infant texture acceptance of Tsabana as nice, acceptable or not nice. In contrast, the majority who perceived the texture acceptance as very nice attained either no schooling/standard one to seven (73.9%) and not a secondary level or higher (26.1%). It could be speculated that caregivers who attained a higher education level may be more critical of such attributes such as the texture acceptance of Tsabana. Most (59%) of the caregivers indicated that they did not receive any information regarding Tsabana from the clinic personnel. Caregiver education on Tsabana and infant nutrition will impart sufficient knowledge and skills to prepare, store and adequately feed Tsabana to their infants as well as provide a variety of foods in adequate amounts to contribute to their optimal growth and development. This is a vital undertaking as it was evident from the study that most of the factors that influenced the acceptance of Tsabana were the product use factors. The study additionally found that foods such as meat, poultry and fish, as well as fruit and vegetables, which should be included in the daily dietary provision, were provided to most of the study infants on a weekly basis only.
