Breiter, Abbe Michelle. "Effects of nutrition education on the nutrition knowledge of future aerobic dance instructors." FIU Digital Commons, 1997. http://digitalcommons.fiu.edu/etd/1805.
Full textAbstract:
The effectiveness of nutrition education on the nutrition knowledge of future aerobic instructors was studied. Forty-seven subjects participated in the study. The experimental group (n=31) chose to and paid for a two-hour per week session of structured nutrition education for four weeks, the control group (n=16) did not. A nutrition knowledge test was completed by all subjects before and after the intervention. Results were analyzed for relationships between subject's nutrition knowledge and age, gender, educational background, income, and body mass index. No significant differences were found between the groups. The results showed that prior to any formal nutrition education, fitness instructors in the experimental and control groups had low nutrition knowledge (8.06%±16.4% and 4.38%±4.12%, respectively). Post-intervention nutrition knowledge significantly improved (p

Full textAbstract:
The purpose of this study was to develop a developmentally appropriate new nutrition education tool, the Rainbow Diet for Children (RDFC), to encourage and aid parents in feeding their children according to current national recommendations. In phase I of the study, the RDFC was developed. Foods were grouped based on color. This grouping provided 11 food groups and foods that provide adequate nutrition for children ages 3-6 years. Using a focus group theoretical diets/foods selections in the RDFC were tested for nutrition adequacy.
Phase II of the study consisted of actual testing of the RDFC with children. Nutrition intervention was given to children at two Montessori Schools in Miami, FL. The RDFC and the Food Guide Pyramid (FGP) were used as nutrition education tools with different groups of children. Children and their parents were encouraged to follow one of the food guides for two weeks. Fifteen healthy children followed the food guides (9 children followed the RDFC and 6 the FGP) while 7 children served as control subjects. Pre and post nutrition analyses were conducted for all three groups.
A pre and post intervention comparison revealed three significant differences. For the FGP group cholesterol intake was significantly (p<0.006) increased and thiamin intake was significantly (p<0.022) decreased. For the control group there was a significant increase (p<0.005) in the vitamin A intake.
For the inter group mean change scores (posttest-pretest) two significant differences were found. First, cholesterol intake in the RDFC was significantly (p<0.045) decreased while for the other two groups it increased significantly. Furthermore, the mean monounsaturated fat intake for the RDFC group significantly decreased (p<0.047) from pre to post, whereas in the other two groups it was increased. These findings support our hypothesis that it is possible to create an alternative meal planning system for 3 to 6 year old children. The RDFC group had adequate nutritional intake while following the rainbow diet meal plan.

Full textAbstract:
The purpose of this study was to describe and inform registered dietitians (RDs) in the State of Florida what insurance companies are providing in terms of medical nutrition therapy (MNT) coverage.
A questionnaire was developed to encompass major MNT reimbursement stipulations such as policies, specific diseases coverage, specific Current Procedural Terminology (CPT) codes and descriptors, use of the medical necessity letter and nutrition cost benefits analysis (CBA). The questionnaire, encompassing 27 plans (HMO, PPO, Indemnity, Medicare, Medicaid), also served as a MNT promotional tool for 11 top administrators from insurance companies (10 private, 1 government) around the State of Florida. The results showed that 78% of all plans reimbursed for MNT caseby- case even without specific MNT policies. Sixty-seven percent of the plans would approve for MNT reimbursement with a medical necessity letter. Half of these top administrators showed an optimistic interest in using nutrition CBAs, case studies and practice protocols for creating MNT policies. The top ranked CPT codes were found to be 99204 (1), 99202 (2), 99201 (2), 99203 (3). The most recognized corresponding descriptors with the CPT were MNT, disease management skills and training and nutritional counseling.
This questionnaire may be used to create additional MNT reimbursement audits or research. The results given in this study can aid RDs in proper documentation on insurance claim forms, usage of the medical necessity letter, nutrition CBAs, practice guidelines and case studies for successful MNT reimbursement.

Full textAbstract:
Dietitians are responsible for recommending artificial nutrition and hydration (ANH) for elderly patients with a diminished mental capacity. Research is non-existent regarding how the beliefs of dietitians influence their recommendations; however, data are available on the attitudes of physicians and nurses regarding ANH. This study was designed to determine how the beliefs of dietitians and nurses affect their decisions regarding administering ANH. Dietitians and nurses, 1500 of each, were asked to agree or disagree with thirteen belief statements related to ANH. The participants also recommended ANH for eight scenarios, which depicted elderly patients with different moods and mental capacities. Results indicated dietitians significantly (p<0.001) more than nurses agreed with the belief statement "when in doubt feed". In all the scenarios, dietitians recommended ANH significantly (p<0.001) more than nurses. Nurses would recommend a trial (p<0.01) or not recommend (p<0.01) ANH more than dietitians. Also, a greater percentage of professionals had a tendency to recommend feeding for the happy patient rather than the unhappy patient. A patient's mood may influence a professional's decision as whether or not to recommend ANH. Dietitians are more likely to recommend ANH to elderly patients with a diminished mental capacity whereas nurses are less aggressive in their recommendations.

Abstract
Parenting Nutrition Skills Workshops: An Evaluation of Facilitated Group Discussions to Enhance Parenting Nutrition Self-Efficacy
By: Lisa Dawes, RD, CDE
This research study was conducted to determine the effectiveness of using facilitated group discussion (FGD), a less traditional method of nutrition education, for increasing parents’ feelings of self-efficacy in their ability to make nutrition-related decisions, and to set and enforce nutrition-related boundaries with their children.
Childhood obesity is on the rise; poor food choices, portion control, and inactivity are identified as contributing causes. Parents play a major role in creating healthy habits and providing a well-balanced diet for their children. Caregivers who act as the nutrition and behavior gatekeepers were targeted in this intervention. The objective of the current study was to enhance parenting nutrition education and identify barriers to healthy feeding practices in order to optimize nutrition and eating behavior.
Twenty-one parents and three grandparents (n = 24) of preschool and school-aged children participated in one-hour FGD parenting nutrition skills workshops. Parent volunteers participated in one of four workshops in a Central California community. Prior to the workshop, topics for discussion were chosen from common feeding issues determined in the literature such as food-related decisions at various locations (home, school, dining out, on the road); feeding jags; and dealing with a picky eater.
Parents completed validated questionnaires both before and immediately following the workshops. Two weeks after the workshops, parents were interviewed by telephone to measure longer-term impact of the FGD. Pre- and post-workshop questionnaires demonstrated that mean self-confidence levels significantly increased for the ability to set and enforce nutrition-related boundaries for their children directly after, and two weeks after participating in the FGD. Parents also demonstrated an increase in mean self-confidence levels in their ability to purchase nutritious foods and offer those foods to their children two weeks after participating in the FGD. Behaviors associated with an authoritative parenting style—such as modeling healthy eating; encouraging healthy food intake; and offering healthy foods without forcing the child to eat—were significantly higher two weeks after participating in the FGD. Significance may be attributed to the method of information delivery (FGD), the curriculum Feeding the Kids (FtK), or authoritative parents being more receptive to receiving new information, or a combination of all three.
Overall, research results suggest that the use of FGD, coupled with a visual tool such as the Chat Mat created for this project, increased parents’ feelings of self-efficacy and elicited positive nutrition-related behaviors in adopting healthy feeding strategies for their children.

Buckmire, Dianne C. "Sources of nutrition information for persons living in Trinidad and Tobago." FIU Digital Commons, 2010. http://digitalcommons.fiu.edu/etd/1941.
Full textAbstract:
Health consumers worldwide obtain nutrition information from various sources; however, the sources Trinidadians and Tobagonians accessed were unclear. This cross-sectional, descriptive study ascertained from which sources Trinidadians and Tobagonians obtained nutrition information. Participants (n = 845) were surveyed with questions regarding demographics and nutrition information sources. Nearly 100% agreed nutrition information was important. Persons 18-64 years old mainly accessed print media (p<0.01) and ≥ 65years old predominantly accessed the non-print media. Significantly more tertiary educated people, ≥ 35 years old, retrieved information from print media (p=0.001), health care professionals (p=0.001), food labels (p=0.006), and non-print media (p=0.03) when compared to those < 35 years with similar education. Tertiary educated people (67%), selected the Internet when compared to those with without tertiary education (33%) (p<0.001). Knowing the nutrition information sources accessed, dietitians will be able to provide consistent, accurate, age specific nutrition information and promote healthy eating among Trinidadians and Tobagonians.

Baker, Holly Jean. "Physical activity and nutrition related variables in hispanic and non-hispanic college students." FIU Digital Commons, 2000. http://digitalcommons.fiu.edu/etd/1375.
Full textAbstract:
It has been estimated that one in four adults have sedentary lifestyles. In addition there appears to be an increase in obesity across the life span. It is of great importance to the health of this nation to understand how to promote more active lifestyles through the identification of lifestyle behaviors of active individuals and potential predictors of physical activity (PA). Seven hundred and seventy-seven college students were surveyed to investigate the relationship between nutrition related variables (i.e., dietary restraint, nutrition knowledge, food choice and body weight concerns) and PA. In this study, over half of the students reported doing 30 minutes of moderate intensity PA daily. Vigorously active males and females chose low fat foods more often than the less active group. Exercisers and non-exercisers had similar nutrition knowledge. The results of this study suggest that students who are more active are more conscience about making healthier food choices.

Duncan, Alyssa Renee. ""Nutrition facts" label use in the selection of healthier foods by undergraduate students." FIU Digital Commons, 1996. http://digitalcommons.fiu.edu/etd/3239.
Full textAbstract:
Use of "Nutrition Facts" panel on food labels was studied in the selection of healthier substitutes for foods normally consumed by 276 undergraduates, mean age, 19.7+2.5 years. Among 1095 label pairs (3.97 per student), 80.6% included a "healthier" substitute. Most common food categories were cookies/bars/tarts (12.8%), cereal (11.8%), chips/crackers (11.1%), beverages (10.2%) and breads/muffins (9.1%). Up to three errors were recorded per label pair, with 384 total errors made, including failure to adjust for serving size (34%), use of pre-NLEA labels (30%), comparison of unlike foods (16%) and unclear comparisons or missing labels (19%). Among 3295 nutrient comparisons, total fat (23.6%), calories (18.4%) and sodium (11.7%) were cited most often. Substitutes were a little (1-10% difference) to a lot healthier (>51% difference) for 83% of nutrients. Sixty percent would purchase healthier foods again or look for other substitutes and 47% stated they preferred the substitute's taste or thought it equivalent.

Brain, Urrunaga Carmen Teresa. "Elder malnutrition: A meta analysis of studies using the nutrition screening initiative determine checklist." FIU Digital Commons, 1997. http://digitalcommons.fiu.edu/etd/1786.
Full textAbstract:
To demonstrate the extent of elder malnutrition risk in this country, a meta analysis of 30 studies that used the Nutrition Screening Initiative's "DETERMINE Your Nutritional Health Checklist" was conducted. The studies were divided into three categories: Elder Populations in Healthcare Related Systems (HS), Elder Meal Program Participants (MP), and General Community Residing Elder Population (GC). HS was sub-divided into Hospital Inpatient/Clinic Outpatient and Long Term Care/Home Care. The MP population were identified as Congregate or Home Delivered meal participants. Overall, results indicate that 63% of elders are at moderate (32%) or high (31 %) risk of malnutrition. Home Delivered Meal Participants and Hospital Inpatient/Clinic Outpatients are most likely to be at high risk of malnutrition (49.5% and 49.1%, respectively). Individuals least likely to be at high malnutrition risk are the General Community Residing Elder Population (17.5%) and Congregate Meal Participants (22.5%).

Chisholm, Martha M. "The effect of total parenteral nutrition (TPN) on zinc (Zn) retention in the tissue of rats." FIU Digital Commons, 1995. http://digitalcommons.fiu.edu/etd/2342.
Full textAbstract:
Zn is regularly added to TPN solutions, however, requirements are poorly understood. This research investigated whether or not the route of Zn intake (oral vs parenteral) changes Zn concentration in rat tissues. Twenty-four male Fischer-344 rats were equally and randomly assigned to one of four groups (n=6): control (CON), baseline (BS), orally fed (OF), and intravenously fed (IV). After fifteen days of feeding, organs and sera were collected and analyzed for Zn by atomic absorption spectrophotometry. Of the nine tissues analyzed, the Zn concentrations in the liver, kidney, and lung of the IV rats were significantly higher (p<1.l) than those of the CON, BS, and OF rats. Results indicated that rats fed intravenously with Zn displayed increased Zn concentrations in liver, kidney and lung tissues, and that the concentration of Zn in the serum may not reflect tissue Zn levels. This suggests that the route of Zn intake affects tissue Zn concentration.

Full textAbstract:
This descriptive study examined whether discharge planning ensures that food and nutrition services are provided to older adults following hospital discharge. The questionnaire was distributed to discharge planning professionals in 11 South Florida hospitals. Of the 84 respondents (88% response rate), most were female nurse case managers. Almost all reported job barriers including excessive patient loads, too many responsibilities, and limited community services. While physicians, registered nurses, social workers, physical therapists, were deemed "very important" in discharge planning,registered dietitians were not, and almost half consulted them infrequently, if at all. Over 84% said nutrition-related medical conditions/factors, "strongly influenced" discharge planning. Many did not have adequate information about nutrition-related community resources, eg, home delivered meals, food stamps, outpatient registered dietitians. Therewere no universal approaches in meeting the nutrition needs in 6 case scenarios. More communication among community services and hospitals is needed.

Casazza, Krista. "A computer based approach to improve the dietary and physical activity patterns of a diverse group of adolescents." FIU Digital Commons, 2006. http://digitalcommons.fiu.edu/etd/2022.
Full textAbstract:
Diet and physical activity patterns have been implicated as major factors in the increasing prevalence of childhood and adolescent obesity. It is estimated that between 16 and 33 percent of children and adolescents in the United States are overweight (CDC, 2000). Moreover, the CDC estimates that less than 50% of adolescents are physically active on a regular basis (CDC, 2003). Interventions must be focused to modify these behaviors. Facilitating the understanding of proper nutrition and need for physical activity among adolescents is the first step in preventing overweight and obesity and delaying the development of chronic diseases later in life (Dwyer, 2000). The purpose of this study was to compare the outcomes of students receiving one of two forms of education (both emphasizing diet and physical activity), to determine whether a computer based intervention (CBI) program using an interactive, animated CD-ROM would elicit a greater behavior change in comparison to a traditional didactic intervention (TDI) program. A convenience sample of 254 high school students aged 14-19 participated in the 6-month program. A pre-test post-test design was used, with follow-up measures taken at three months post-intervention.
No change was noted in total fat, saturated fat, fruit/vegetables, or fiber intake for any of the groups. There was also no change in perceived self-efficacy or perceived social support. Results did, however, indicate an increase in nutrition knowledge for both intervention groups (p<0.001). In addition, the CBI group demonstrated more positive and sustained behavior changes throughout the course of the study. These changes included a decrease in BMI (ppre/post <0.001, ppost/follow-up<0.001), number of meals skipped (ppre/post <0.001), and soda consumption (ppre/post =0.003, ppost/follow-up =0.03) and an increase in nutrition knowledge (ppre/post <0.001, ppost/follow-up<0.001), physical activity (ppre/post <0.05, ppost/follow-up<0.01), frequency of label reading (ppre/post <0.01) and in dairy consumption (ppre/post <0.03). The TDI group did show positive gains in some areas post intervention, however a return to baseline behavior was shown at follow-up. Findings of this study suggest that compared to traditional didactic teaching, computer-based nutrition and health education has greater potential to elicit change in knowledge and behavior as well as promote maintenance of the behavior change over time.

Full textAbstract:
The relationship between the frequency of eating, physical activity and Body Mass Index (BMI) was investigated. Seventy five women, aged 24 to 55, were recruited from Florida International University. Via interview, subjects provided information regarding demographics and habitual eating frequency over 24-hours, and completed both the Baecke Questionnaire of Habitual Physical Activity and the Health Insurance Plan of New York Questionnaire on Physical Activity. Pearson correlations and partial correlation coefficients were used to assess the relationship between eating frequency, physical activity, age, and BMI. Results revealed significant positive correlations between eating frequency and total physical activity scores, and leisure time physical activity scores, but not between eating frequency and physical activity on the job. Partial correlations suggest that there may be an effect of eating frequency on BMI both through an effect on physical activity and through another mechanism. These results suggest that more frequent eaters tend to be more physically active, which may partially explain why lower body weights is associated with more frequent eating.

Full textAbstract:
Purpose: The purpose of the study was to examine Jamaican adolescents in a school setting, for risk factors of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs).
Methods: A descriptive epidemiological cross-sectional study of 276 Jamaican adolescents (112 males and 164 females) ages 14-19 years (15.6±1.2), randomly selected from grades 9-12 from ten high schools on the island. Thirteen risk factors were examined. Risk factors were compared with BMI levels and demographics. A sub-study validated finger prick testing of fasting blood glucose, total cholesterol, and HbAlc versus venous testing in 59 subjects.
Results: Prevalence of overweight was 33.0% (n=91) with mean BMI of 23.74±7.74. Approximately 66.7% of subjects reported > 3 risk factors. The number of T2DM and CVDs risk factors increased for subjects with BMI above 25. One third of the overweight subjects were classified with the metabolic syndrome. High BMI was associated with high waist circumference (r =.767, p
(r = .180, p.05). Percentage bias for the methods of blood testing met the reference standards for fasting blood glucose but not for total cholesterol and HbAlc. Bland Altman tests of agreement between the two methods indicated good agreement for all three tests.
Conclusion: Jamaican adolescents are at high risk for T2DM and CVDs as seen in other study populations. Effective programs to prevent T2DM and CVDs are needed. Family history of diseases, anthropometric measures, and gender identified more subjects at risk than did the biochemical measures. Comparison between finger prick and venous blood methods suggested that finger prick is an adequate method to screen for risk factors in children and adolescents.

Batista, Sonia M. "Job satisfaction of dietitians in South Florida." FIU Digital Commons, 1999. http://digitalcommons.fiu.edu/etd/1432.
Full textAbstract:
The purpose of this study was to examine job satisfaction of dietitians in South Florida and to identify significant differences in job satisfaction between dietitians working in traditional versus non-traditional settings.
A job satisfaction questionnaire was developed, validated, and mailed to dietitians in Palm Beach, Broward, Dade, and Monroe counties. Out of 600 questionnaires mailed, 203 surveys were returned and 187 were valid and analyzed statistically. Seventy three percent of subjects practiced in traditional and 17% in non-traditional settings. Eighteen percent of 187 subjects surveyed reported feeling dissatisfied with their jobs and 59% reported feeling satisfied. There was no significant difference in satisfaction due to practice settings (traditional versus non-traditional). The subjects reported satisfaction with co-workers and supervisors. The two major areas where dissatisfaction was reported were compensation and professional recognition.
The results showed that the majority of dietitians in South Florida are, in general, satisfied with their jobs. Although dietitians' salaries have increased by approximately 80% since 1982, compensation was still viewed as inadequate by 48% of the subjects, given dietitians' education, skills and experience.
Because legislation to approve reimbursement of medical nutrition therapy is pending, increase in dietitians' knowledge of reimbursement issues is recommended. Dietitians must also promote assertively their valuable contribution to wellness, health, and the treatment of disease.

Full textAbstract:
In a cross-sectional study design, risk factors for coronary heart disease (CHD) were evaluated in three groups: 66 Afro Caribbeans (FBCA) living in the US for less than 10 years, 62 US-born Afro Caribbean (USBCA) and 61 African American (AA) adults (18-40 years), with equal numbers of males and females in each group. Socio-demographic, dietary, anthropometric and blood pressure data were collected. Fasting blood glucose, blood lipids and high-sensitivity C-reactive protein (hs-CRP) were determined.
The USBCA and AA participants compared to the FBCA participants consumed significantly (p< 0.05) more mean total fat (g) (66.3 ± 41.7 and 73.0± 47.8 vs. 52.8± 32.3), saturated fat (g) (23.1± 14.9 and 24.9± 15.8 vs. 18.6 11.5), percent energy from fat (%) (33.1 ± 6.5 and 31.4 ± 6.4 vs. 29.3 ± 6.8), fat servings (1.8 ± 1.2 and 1.5 ± 1.0 vs. 1.2 ± 0.9), dietary cholesterol (mg) (220.4 ± 161.9 and 244.1 ± 155.0 vs. 168.8 ± 114.0) and sodium (mg) (2245.2 ± 1238.3 and 2402.6 ± 1359.3 vs.1838.0 ± 983.4) and less than 2 servings of fruits per day (%) (86.9 and 94.9 vs. 78.5). These differences were more pronounced in males compared to females and remained after correcting for age. Also, the percentages of USBCA and AA participants who were obese (17.1% and 23.0%, respectively) were significantly (p< 0.05) higher compared to FBCA (7.6%) participants. More USBCA and AA than FBCA individuals smoked cigarettes (4.8% and 6.6% vs. 0.0%) and consumed alcoholic beverages (29.0% and 50.8% vs. 24.2%). The mean hs- CRP level of the AA participants (2.2 ± 2.7 mg/L) was significantly (p< 0.01) higher compared to the FBCA (1.1 1.3 mg/L) and USBCA (1.3 ± 1.6 mg/L) participants.
The FBCA participants had a better CHD risk profile than the USBCA and AA participants. Focus should be placed on the ethnic and cultural differences in a population to better understand the variations in health indicators among different ethnic groups of the same race. This focus can provide healthcare professionals and policy planners with the opportunity to develop culturally sensitive programs and strategies for the improvement of health outcomes.

Full textAbstract:
The objective of this thesis was to determine how the availability of tropical fruit beverages, familiar to Hispanics, would affect fluid intake of Hispanic and non-Hispanic residents of a 120-bed nursing home. Beverage acceptance and intake were measured for three days with the following beverage offerings (including coffee): four fruit beverages usually served in the facility or two of the usual fruit beverages combined with two tropical fruit beverages. The presence of the tropical fruit beverages on the hydration cart significantly increased acceptance and intake in women but not men, regardless of ethnicity. Hispanic females chose and drank (ps < .01) more tropical fruit beverages than did their non-Hispanic counterparts. During the study residents consumed greater than six ounces of beverage 80% of the time and greater than ten ounces 57% of the time. Between-meal fluid intake in this population can be stimulated by offering generous servings (10-12 oz) of a variety of palatable beverages, including ethnic favorites.

Full textAbstract:
The purpose of this study was to determine if food safety education influences food safety knowledge, attitude and behavior among inner city public school foodservice employees. Knowledge, attitude and behavior of an experimental group (n=22) was assessed before and after 3-hour food safety training and compared with a control group (n=10) that received no food safety training. We hypothesized that those who received food safety training would have improved knowledge, attitude and behavior towards food safety issues compared to those who did not receive training.
Results showed that food safety training significantly increased (p<0.001) the knowledge of foodservice employees compared to those who didn’t receive the training. However, the 3-hour training did not significantly influence attitude or practice of safe food-handling techniques. Education and consistent re-training, coupled with Hazard Analysis and Critical Control Point (HACCP) system, food-handier sanitation certification and frequent supervision may help to increase food safety awareness among foodservice employees.

Full textAbstract:
It is standard practice in acute-care settings to screen patients upon admission to determine whether they need a nutritional assessment; however, there is limited information on the ability of the screening tools to detect patients at nutritional risk. The purpose of this study was to determine (1) the sensitivity and specificity of the screening tool used at Jackson Memorial Hospital and (2) whether a new proposed tool would be more sensitive and specific. Dietitians screened patients upon admission using the existing and proposed tools (n=141). Sensitivity and specificity of these tools in identifying patients at nutritional risk was calculated. Mantel-Haenszel chi-square statistics were used to identify indicators correlated with nutritional risk. A revised tool was tested and found to have a higher sensitivity than the existing tool but lower specificity. Odds ratios indicated that the revised tool had a higher degree of association with nutritional risk than the existing one.

Full textAbstract:
The purpose of this study was to show variations of folate intake, folate food sources, and diet by age, gender, and ethnicity in Metro-Dade Firefighters and to also determine the prevalence of obesity, physical inactivity and history heart disease. Low folate status may play a role in cardiovascular risk via its effect on homocysteine metabolism. Firefighters (n=127) recruited from randomly selected fire stations completed food-frequency and socio-demographic questionnaires.
Significantly (p<.05) more African-Americans failed to meet at least 75% of the dietary reference intake (DRI) for folate than whites or Hispanics. There were significant differences in protein, vegetable, and meat intakes between age groups. Almost 78% of firefighters were overweight (BMI≥25). There were significant (p<.001) differences in BMI among ethnic groups. Older firefighters reported significantly (p<.05) more CVD risk factors than younger firefighters. Metro-Dade firefighters were found to be similar to the general US population in that most of the risk factors, overweight and obesity, high fat intakes, and low folate intake were modifiable and diet related.

Full textAbstract:
The purpose of this study was to determine the racial and ethnic differences on body image perceptions and weight concerns of fourth grade girls. A purposive sample of 182 fourth grade girls were eligible to participate, 166 were included in the data analysis. The Children's Eating Attitude Test (ChEAT) and a Dieting and Demographic Questionnaire (DDQ) were used to determine eating attitudes of fourth grade girls. A pictoral instrument that was modified from the original was used to assess body image. Anthropometric data was assessed and body mass index (BMI) values were used to classify subjects into percentiles.
Results revealed that 56% of all fourth grade girls studied wanted to be thinner and 53% had tried to lose weight. Significantly more non-Hispanic white (NHW) girls reported wanting to be thinner than non-Hispanic black (NHB) and H girls (65.5% vs.32% and 47%, respectively, P=0.005) No significant racial/ethnic differences were revealed for the ChEAT scores. However, 19% of all subjects studied fell into the category indicative of anorexia nervosa. H girls who were less than the 85" %tile for BMI chose significantly smaller figures as their perceived body image (3.5±0.7) than both NHB and NHW girls (4.0±0.6 and 3.9±0.5, respectively, P<0.01).
These findings demonstrated that weight concerns were prevalent among girls ages 9- 11 years. NHW and H girls may have more concerns about their body size and shape than their NHB counterparts. Implementing intervention programs at an early age may prevent eating disorders in adolescence and adulthood.

Full textAbstract:
The purpose of this research was to study the nutritional status of United States Coast Guard Law Enforcement Detachment (USCG/ LEDET) personnel before and after prolonged travel at sea. To date there is no information available regarding the nutritional status of Coast Guard personnel. Forty-seven subjects were studied in total, each served as their own control. Demographic and health history data was collected at baseline. Dietary and exercise data was collected before and during the deployment. Body composition was determined before and after a deployment.
The results of this study revealed that the USCG/LEDET personnel had high cholesterol and decreased fiber intakes. Cholesterol intake during deployment (516.8±239.7 mg/day) was significantly higher (p= 0. 047) than pre-deployment (448.2 ± 144.3 mg/day).
Fiber intake was significantly lower than recommended (p
The results of this study indicate that LEDET personnel are put at higher nutritional risk while deployed and also have increased negative health behaviors associated with risk for Cardiovascular Disease (CVD) and other related diseases. This is crucial information for the USCG so that action can be taken to improve the physical well being of their personnel.

Chester, Deirdra Nicole. "The relationship of spirituality and the health promoting behaviors of diet and exercise of African American women." FIU Digital Commons, 2003. http://digitalcommons.fiu.edu/etd/2159.
Full textAbstract:
Public health data show that African-Americans have not adopted health-promoting behaviors of diet and exercise. Spirituality, important in the lives of many African-American women, may be associated with health-promoting behaviors. This study was designed to determine how spirituality relates to health-promoting behaviors in African-American women. Burkhardt's theoretical framework for spirituality was adopted and measures were selected for the three elements of the framework: connectedness with self, others, and environment.
The study used a descriptive cross sectional correlational design to investigate the relationships of the independent variables of spirituality, sociodemographics, and BMI, to the dependent variables of diet and exercise, to answer the two primary questions: What is the role of spirituality in impacting the health-promoting behaviors of African- American women? Of the independent variables of spirituality, sociodemographics, and BMI, which are the best predictors of diet and exercise? C
entral and South Floridian African-American women (n=260) between 18 and 82 years of age completed several questionnaires: Rosenberg's Self-Esteem Scale, Health Promoting Lifestyle Profile II, Spiritual Perspective Scale, Brief Block Food Frequency, and socio-demographic information.
Hierarchical regression identified 40% of the variability of diet to be explained by socio-demographic (education) and spirituality variables (stress management and health responsibility) (p<.001). Twenty-nine percent of the variability of exercise was explained by socio-demographic (education) and spirituality variables (stress management) (p<.001). Canonical correlation analysis identified a significant pair of canonical variates which indicated individuals with good nutrition (.95), increased physical activity (.79), and healthy eating (.42) also had better stress management (.88), better health responsibility (.67), higher spiritual growth (.66), better interpersonal relations (.50), more education (.49), and higher self-esteem (.33). The set explained 57% of the variability (p<.001).
An understanding of the factors that influence these women's decision to utilize health-promoting strategies could provide health professionals with additional information to enable them to design culturally and spiritually related health messages for African-American women. The findings of this present study speak of the importance of focusing on stress management, health responsibility, spiritual growth, interpersonal relations and self-esteem along with diet and exercise; this will likely provide improvement in the health-promoting behaviors of African-American women.

Collins, Nancy. "Facing a paradigm shift in professional credentialing: preparedness of registered dietitians for professional development 2001." FIU Digital Commons, 2000. http://digitalcommons.fiu.edu/etd/2411.
Full textAbstract:
In the year 2001, the Commission on Dietetic Registration (CDR) will begin a new process of recertifying Registered Dietitians (RD) using a self-directed lifelong learning portfolio model. The model, entitled Professional Development 2001 (PD 2001), is designed to increase competency through targeted learning. This portfolio consists of five steps: reflection, learning needs assessment, formulation of a learning plan, maintenance of a learning log, and evaluation of the learning plan. By targeting learning, PD 2001 is predicted to foster more up-to-date practitioners than the current method that requires only a quantity of continuing education hours. This is the first major change in the credentialing system since 1975. The success or failure of the new system will impact the future of approximately 60,000 practitioners. The purpose of this study was to determine the readiness of RDs to change to the new system. Since the model is dependent on setting goals and developing learning plans, this study examined the methods dietitians use to determine their five-year goals and direction in practice. It also determined RD's attitudes towards PD 2001 and identified some of the factors that influenced their beliefs. A dual methodological design using focus groups and questionnaires was utilized. Sixteen focus groups were held during state dietetic association meetings. Demographic data was collected on the 132 registered dietitians who participated in the focus groups using a self-administered questionnaire. The audiotaped sessions were transcribed into 643 pages of text and analyzed using Non-numerical Unstructured Data- Indexing Searching and Theorizing (NUD*IST version 4). Thirty-four of the 132 participants (26%) had formal five-year goals. Fifty-four participants (41 %) performed annual self-assessments. In general, dietitians did not currently have professional goals nor conduct self-assessments and they claimed they did not have the skills or confidence to perform these tasks. Major barriers to successful implementation of PD 2001 are uncertainty, misinterpretation, and misinformation about the process and purpose, which in turn contribute to negative impressions. Renewed vigor to provide a positive, accurate message along with presenting goal-setting strategies will be necessary for better acceptance of this professional development process.

Full textAbstract:
This study investigated the impact of an acute bout of physical activity on postexercise energy intake (PE-EI) in overweight females who were dieting with high restraint (D-HR) and non-dieting with either high restraint (ND-HR) or low restraint (ND-LR). PE-EI at lunch and 12-hours after was compared on the exercise (E) and a nonexercise (NE) day.
There was a significant interaction (F (2,33)= 4.12, p = 0.025) of dieting/restraint status and condition (E vs. NE day) on the 12-hour El. The D-HR ate 519 ± 596 kcal more on the E than on the NE day; while the ND-HR ate 177 ± 392 kcal less on the E than on the NE day.
The results of this study demonstrate that the impact of exercise on PE-EI is determined by both a physiological and psychological response. Dieting status, dietary restraint, level of disinhibition and cognitive factors may influence PE-EI and weight.

The objective was to develop and validate a method for estimating food intake of nursing home residents. The study was conducted with certified nursing assistants (CNAs) at a 180-bed nursing facility. CNAs assisted in the development of the new method by providing feedback on existing estimation methods. Four simulated resident trays were used to estimate both food intake and overall meal intake. Twelve CNAs' intake estimates for 34 simulated food items (n=384 estimates) were compared to weighed values. Eightyfive percent of the 384 intake estimates for the simulated food items were correct; Cohen's kappa was 0.80, p

Full textAbstract:
The purpose of this study was to investigate the efficacy of using monosodium glutamate (MSG) as a means to increase palatability and prospective consumption of vegetables at a congregate meal site with Cuban-American clients. Thirty to 32 subjects participated in hedonic testing each day. MSG-enhanced (2 g MSG/500 g vegetable) and non-enhanced beets, string beans, carrots and peas were evaluated for palatability, preference and prospective consumption. Results showed that MSG significantly increased both palatability and prospective consumption of string beans (ps < .05) but not of the other 3 vegetables tested. These findings provide some evidence that MSG can be used to increase the palatability of vegetables served at congregate meal sites. However, these results suggest that older adults may not find the palatability of some vegetables to be improved by MSG and that optimal flavor enhancement cannot be achieved by adding the same amount of MSG to every vegetable.

Full textAbstract:
Fat modified foods are widely available and have the potential to help individuals with diabetes, including children, achieve a lower total fat and saturated fat intake. Sixty-three pre-adolescents (10-13 years) with insulin-dependent diabetes mellitus (IDDM or Type I), and 60 without diabetes (boys, n=54; girls, n=69) were tested to determine their beliefs and attitudes towards high-fat and reduced-fat foods. In addition, both children and parents were asked about the child's use of low fat foods i.e., how often the parent bought or encouraged their child to eat reduced-fat food; how strongly the doctor or dietitian promoted the use of reduced-fat foods, and the child's concern about dietary fat. In this study, preadolescents with diabetes were not more likely than those without diabetes to use fat-modified foods. Parental and health care practitioner encouragement is associated with greater use of these products by children.

This study investigated the effect of providing free-access to several fat-modified foods on dietary energy and fat intake in free-living individuals with and without diabetes mellitus. Five low/no-fat products or their regular-fat versions were provided to volunteers to take home and use for 3 days. Energy and nutrient intakes of all foods consumed were determined through a weighed food diary and by weighing the food provided before and after consumption. Fifteen individuals with diabetes and 15 case-matched controls without diabetes participated in the study. Individuals with diabetes and controls responded similarly to the fat-modified foods. In both groups there was a significant reduction in the percent of kcals and grams of fat consumed during the low-fat condition compared to the regular-fat condition (p

Full textAbstract:
The purpose of this study was to establish baseline information on the way in which acculturation affects Cuban Americans' dietary habits. In addition, the study explored differences in post-migration food preference between diabetic and non-diabetic Cuban Americans. The study was a cross-sectional survey utilizing a convenient sample of Cuban Americans living in Miami-Dade County. One hundred seventy-eight first generation Cuban Americans completed the Multidimensional Acculturation Survey for Cuban Americans (MAS-CA) which included a Dietary Bidimensional Acculturation Scale (D-BAS). Food acculturation scores for Cuban and American food choices were calculated from the D-BAS. Overall, the mean Cuban food score (CFS) (31.8 ± 9.4) was significantly higher (P < 0.001) than the mean American food score (AFS) (15.7 ± 8.6). The Cuban Americans who participated this study preferred Cuban foods to American foods. Moreover, the higher the level of acculturation, the smaller the difference between the CFS and the AFS. There was a statistically significant (P < 0.001) negative relationship between the CFS and the acculturation score. Lower acculturation language scores were associated with higher CFS. Regardless of the presence of diabetes, Cuban Americans preferred Cuban foods. Having type 2 diabetes negatively influenced the subjects' alcohol consumption. It was demonstrated that the instrument developed for this study (D-BAS) was able to measure the subject's dietary acculturation. This instrument can be used as a measure of acculturation, either singularly or in a combination with other measures. In designing nutrition intervention programs, it may be necessary to determine food acculturation levels in order to have more effective programs.

Full textAbstract:
The primary objective of this study was to assess the psychosocial risk factors for eating disorders in Hispanic (70%) and Non Hispanic (30%) female university students (n= 618). Risk factors were assessed with the Psychosocial Risk Factor Questionnaire (PRFQ) and its four sub-scales. There was a significant difference in the score for Concern (F = 243, p .046) and Media Pressure (F = 367, p < .006) by ethnic group. African Americans had a significantly lower mean score (3.27 ± 028) for media pressure than all other ethnic groups. There was a significant difference in total PRFQ score (F = 2.52, p < .02l) and the score for perception (F = 2.18, p< .044) among the Hispanic ethnic groups. These results indicate that there are differences among major ethnic groups as well as among Hispanic ethnic groups in terms of the psychosocial factors associated with the risk of eating disorders.

The validity of serum transthyretin as a nutrition assessment parameter in hemodialysis patients was investigated. Fifty-one subjects (39% male and 61 % female; 53% black, 28% white, 12% Hispanic, 7% Other) receiving hemodialysis for 30 24 months (mean SD) and a total of 36 26 months of renal replacement therapy were followed for six months. Serum transthyretin, albumin, BUN, creatinine, cholesterol, normalized protein catabolic rate (nPCR), KT/V, weight and 24 hour urine analysis were determined monthly. Etiologies of end stage renal disease were diabetic nephropathy (37%), hypertensive nephrosclerosis (37%). glomerulonephritis (12%), polycystic kidney disease (4%), lupus nephritis (4%), other causes (6%). A significant correlation was found between transthyretin and creatinine, albumin and loss of dry weight (p<0.05). Transthyretin levels <30 mg/dl were found to correlate with urine outputs > 240 cc/24 hours, predialysis BUN < 50 mg/dl and nPCR

The purpose of the research was to determine if a history of colic plays a role in carbohydrate absorption in infants consuming either apple or white grape juice. In this double-blind study, 31 infants (5.0 ± 0.4 months, 7.5 ± 0.9 Kg, 64.1 ± 3.8 cm, 29.2 ±3.4 % fat and 5.1 ± 0.6 Kg fat-free mass) were divided into four groups and were fed 120 ml of either white grape (sorbitol free;1:1 fructose to glucose ratio) or apple (sorbitol 0.5 g/dl; 2.3:1 fructose to glucose ratio) juice. Sixteen of the infants had a history of colic. During the study continuous physical activity (PA) and metabolic rate (MR) were measured for 0.5 hours before and 3.0 hours after juice load using an infant respiratory chamber. Carbohydrate absorption was determined every 30 minutes after juice feeding by breath hydrogen (BH2) gas analysis. Statistical differences between groups were determined by one way ANOVA and by independent t-test.

The purpose of this study was to gain further insight into the relationship between perceived energy expenditure (EE) for physical activity (PA) and age, gender, Body Mass Index (BMI), education, and leisure time PA (LTPA) levels. A 19-item interviewer administered questionnaire was completed by 798 individuals to assess accuracy of perception of EE (in calories) for various types of PA (sedentary, moderate and vigorous). Participants, age 21 to 64 years, were recruited from ten sites of the Department of Motor Vehicles in Miami, Florida. Only 30% were able to accurately assess EE for PA. Higher education and age were associated with greater accuracy. The range for estimated EE for PA was from 0-60,000 calories. These results are of interest as they suggest efforts should be made to educate the public regarding EE for PA in reference to energy balance and weight management.

Zohng, Haoyuan. "Effect of Lipid Source on the Physical and Sensory Quality of Baked Products." DigitalCommons@USU, 2013. https://digitalcommons.usu.edu/etd/1504.
Full textAbstract:
The effect of commercial shortenings (butter, lard, margarine, all-purpose shortenings, soybean oil, and interesterified soybean oil) on the physical and sensory characteristics of baked products was evaluated. Results showed that lipid viscoelastic character, melting point, onset melting temperature (Ton), and melting enthalpy (ΔH) affect the physical qualities of baked products, such as batter density of cake, spread of cookies, and breaking strength of pie crust. With a larger value (less plastic character), less crystal structure is present in the lipid and fewer air bubbles were incorporated into cake batter, which results in a denser batter. With a liquid character, lipid prevents water-flour interaction by coating flour particles, which develops less gluten in pie crust, indicated by its low breaking strength. The ΔH can be extrapolated to the amount of crystalline material in the lipid: the larger ΔH, the more crystalline material. In cookie production, a low ΔH make the lubricant effect of a lipid available larger cookie spread than the one observed in cookies made with a shortening with high ΔH values. The effect of ultrasound (US)-treated interesterified soybean oil (IES) on the quality characteristics of baked goods was also evaluated. US-treated and non US-treated IES were prepared at 32°C and tempered for 48 h at 5 and 25°C. US-treated IES had smaller lipid crystals than non US-treated IES. In cakes, the highest cake batter density was obtained when non US-treated IES tempered at 5°C was used. This was a consequence of the larger lipid crystals obtained under this condition, which had less ability to incorporate air. In cookies, the fewer crystals (more fluid status) present in non US-treated IES tempered at 25°C led to a higher dough density, higher spread, and lower height in the final cookies. Similarly, in pie crust, the larger amount of lipid crystals in US-treated IES contributed to significantly higher height in final pie crust.

Full textAbstract:
Incidence of eating disorders among aerobic instructors in South Florida was studied. One hundred and three aerobic instructors participated in the study (14 males and 89 females). A 40-item questionnaire used to identify eating disorder behaviors and attitudes was completed by the subjects. Subjects were divided into groups based on gender and number of aerobic classes taught per week. Findings indicated that the incidence of anorexia was higher among aerobic instructors from South Florida (1 in 17) than in the general population. Increased number of classes taught per week was associated with an increased prevalence of eating disorder behaviors. Eating disorder “self-descriptors” were also reported more frequently by aerobic instructors who taught 10 or more classes per week. No significant differences were found among genders in reporting of eating disorder behaviors and attitudes.

The purpose of this study was to determine if a short-term nutrition education program could significantly improve the nutrition knowledge (as assessed by the .Nutrition Achievement Test (NAT)) and body composition (as measured by the weight-for-length index (WLI) and body mass index (BMI)) of female cheerleaders aged 7 to 13. Nutrition lessons were presented to the experimental group during a two month treatment period. Using a pre-test, post-test, control group design, and performing two-sample t tests on mean differences (post-test minus pre-test) in BMI, WLI and mean percent correct on the Nutrition Achievement Test (NAT), it was discovered that the experimental group (teams A,C; N=34) did not differ significantly from the control group (teams B,D; N=31) with respect to mean differences (post-test minus pre-test) in WLI (p=0.10), and BMI (p=0.49). However, the experimental and control groups differed significantly with respect to mean difference percent correct NAT scores (p=0.042), with the experimental group improving more than the control. Closer examination revealed the older experimental team (C) improved significantly (p=0.0017), while the younger experimental team (A), did not (p=0.64). Neither of the control groups improved significantly. ANCOVA was performed on the post-test percent correct on the NAT, using the pretest as a covariate, for the 15 experimental and 14 control subjects taking NAT Test 4. ANCOVA revealed that the experimental group’s adjusted post-test mean score was higher than the control's (p<.01). These results suggest that nutrition education may result in significant improvements in the nutrition knowledge of adolescent females enrolled in an extra-curricular cheerleading league and/or program.

There is a significant relationship between nutrition, systemic disease, and oral health. The integration of both nutrition and oral health information into educational programs for dental hygiene and nutrition students is vital for each profession. The purpose of this study was to determine the knowledge levels of dental hygiene and nutrition students in regards to content material pertaining to each discipline. This study attempted to provide baseline data for those teaching in ETSU’s Dental Hygiene and Nutrition programs to determine if modifications in the curricula are needed to better prepare future students. Results indicated that there was not a significant difference between the knowledge levels of ETSU senior dental hygiene students and nutrition students. Despite the absence of a statistically significant difference in responses between dental hygiene and nutrition students, evaluating the low scores from each group of students indicated that there is room for improvement. Students demonstrated strong knowledge in some areas and lack of knowledge in other areas in regards to the relationship of diet, nutrition and oral health. Focusing on the areas where the students scored the weakest should be of interest for both programs.

A comprehensive analysis of precompetition dietary beliefs and behaviors of competitive bodybuilders has yet to be documented in the literature. The purposes of this study were (a) to quantify and document types of supplements competitive male and female bodybuilders consume, (b) to document how much money they spend on them each month, (c) to describe what dietary modifications and behaviors they follow in preparation for a contest and (d) to describe their nutrition beliefs associated with these habits. Three hundred and nine competitive male and female bodybuilders completed questionnaires regarding their precompetition dietary practices. It was found that bodybuilders consume a wide variety of supplements and use a multitude of dietary training practices which vary depending on the training phase. A large percentage of bodybuilders agreed with statements on supplement use and training practices that are unsubstantiated by scientific research.

Boulos, Patricia. "Impact of nutrition education on knowledge and eating patterns in HIV-infected individuals." FIU Digital Commons, 1990. http://digitalcommons.fiu.edu/etd/1749.
Full textAbstract:
Acquired Immune Deficiency Syndrome (AIDS) and impaired or threatened nutritional status seem to be closely related. It is now known that AIDS results in many nutritional disorders including anorexia, vomiting, protein-energy malnutrition (PEM), nutrient deficiencies, and gastrointestinal, renal, and hepatic dysfunction (1-7, 8).
Reversibly, nutritional status may also have an impact on the development of AIDS among HIV-infected people. Not all individuals who have tested antibody positive for the Human Immunodeficiency Virus (HIV) have developed AIDS or have even shown clinical symptoms (9, 10). A poor nutritional status, especially PEM, has a depressing effect on immunity which may predispose an individual to infection (11). It has been proposed that a qualitatively or quantitatively deficient diet could be among the factors precipitating the transition from HIV-positive to AIDS (12, 13).
The interrelationship between nutrition and AIDS reveals the importance of having a multidisciplinary health care team approach to treatment (11), including having a registered dietitian on the medical team. With regards to alimentation, the main responsibility of a dietitian is to inform the public concerning sound nutritional practices and encourage healthy food habits (14). In individuals with inadequate nutritional behavior, a positive, long-term change has been seen when nutrition education tailored to specific physiological and emotional needs was provided along with psychological support through counseling (14). This has been the case for patients with various illnesses and may also be true in AIDS patients as well.
Nutritional education specifically tailored for each AIDS patient could benefit the patient by improving the quality of life and preventing or minimizing weight loss and malnutrition (15-17). Also, it may influence the progression of the disease by delaying the onset of the most severe symptoms and increasing the efficacy of medical treatment (18, 19).
Several studies have contributed to a dietary rationale for nutritional intervention in HIV-infected and AIDS patients (2, 4, 20-25). Prospective, randomized clinical research in AIDS patients have not yet been published to support this dietary rationale; however, isolated case reports show its suitability (3). Furthermore, only nutrition intervention as applied by a medical team in an institution or hospital has been evaluated. Research is lacking concerning the evaluation of nutritional education of either non-institutionalized or hospitalized groups of persons who are managing their own food choice and intake. This study compares nutrition knowledge and food intakes in HIV-infected individuals prior to and following nutrition education. It was anticipated that education would increase the knowledge of nutritional care of AIDS patients and lead to better implementation of nutrition education programs.

Full textAbstract:
BACKGROUND: A consistent care process, clear and concise medical documentation, and standardised nutrition terminology is beneficial for dietetic practice. The Nutrition Care Process (NCP), a contemporary framework to promote critical thinking and systematically address nutrition problems, and its terminology (NCPT, formerly known as IDNT) was developed to suit these purposes. However, this framework has not yet been adopted globally. The basis for this lack of adoption relates to difficulties in traditional face-to-face implementation, including a lack of local NCP experts, time constraints, financial limitations and geographical isolation.
OBJECTIVE: To develop, implement and evaluate an online education portal for NCP implementation, tailored to dietitians in clinical settings internationally. This portal also seeks to develop an online community of practice to enhance the NCP learning experience.
METHOD: The study consisted of three stages and used a number of quantitative and qualitative methods. In Stage one, qualitative focus groups with clinical dietitians were conducted to identify gaps in NCP education and assess needs in relation to an online education portal. This formative research was used to inform the second stage of website development, which was set within the framework of Spiral Technology Action Research (STAR). This approach engaged participants to further inform website development and refine the site prior to launch and implementation of the NCP online education. In the third and final stage, the resulting ‘Dietitians Online Nutrition Care Process (DoNCP)’ www.doncp.com.au, was launched nationally and internationally. The effectiveness of the online education was evaluated and measured by change in knowledge and attitude of dietitians pre- and post-website intervention using the Attitudes, Support, Knowledge of Nutrition Care Process (ASK NCP) questionnaire. Data on country of practice, learning style preferences, work status (full-time vs part-time), years of dietetic experience, and sense of community were also investigated. Qualitative exit interviews were conducted with participants and were triangulated with quantitative outcomes.
RESULTS: A total of 444 dietitians from 35 countries attempted to register on the DoNCP website, with 372 registering successfully and completing the pre-ASK NCP questionnaire. Of these 372 dietitians, 68 (18.3%) completed both pre- and post-ASK NCP questionnaires, and were called ‘Questionnaire Completers (Q completers)’. The 304 dietitians (81.7%) who completed the pre- but not post-ASK NCP questionnaire were called ‘Questionnaire Non-Completers (Q non-completers)’. Q completers (n=68) were similar to Q non-completers (n=304) in aspects of gender, age, country of practice, highest education level, learning style preference, work position, work status, and geographical location of workplace (p>0.05 for all), with the exception of years of dietetic experience (p0.05 for all). After DoNCP website intervention, Q completers (n=68) reported significant improvements in their knowledge of NCP (p0.05 for all). Post intervention, the sense of community for Q completers (n=68) was not significantly associated with the change in NCP knowledge and attitudes scores (p>0.05 for all). The DoNCP website provided a sense of community for dietitians to a certain extent, however, a community of practice did not fully emerge during the finite data collection period.
CONCLUSIONS: The DoNCP website was confirmed as an effective portal to support NCP learning for dietitians at the national and international level, regardless of the sense of community. The knowledge and attitudes scores (value, confidence, support, and training) towards NCP model framework improved following the utilisation of the DoNCP website. The fact that learning style preference was not associated with differences in knowledge and attitude change suggested that the DoNCP website provided a wide range of educational resources to accommodate a range of different learning styles. Participants perceived the DoNCP website as a professional resource that met their needs and enhanced their learning of NCP.

The purpose of this study was to validate the proposed Metaparadigm of Clinical Dietetics. The proposed Metaparadigm of Clinical Dietetics is the most abstract level of the profession's body of knowledge and is a statement of seven domains of concern. The seven domains are Reference Person, Human Condition, Practitioner Actions/Attitudes, Practitioner Environment, Client Actions/Attitudes, Client Environment and Nutraceuticals and are characterized by ninety-four knowledge topics. A further purpose was to determine comparative relevance of these ninety-four knowledge topics to other health professionals and nutritional scientists. A descriptive-correlational-factor-analytical design was used for this study. An expert panel of clinical dietetic practitioners and an extensive literature review were used to develop the mailed survey instrument. A random sample of five hundred clinical dietitians was selected from members of thirteen clinical Dietetic Practice Groups of The American Dietetic Association. One hundred thirty-six surveys were returned for a response rate of twenty-seven percent.

Full textAbstract:
Changing demographics in the United States to a minority-majority culture require health care professionals who are culturally competent to provide appropriate care to patients. In a university in the Mid-Atlantic region of the United States, a gap existed between student education and the culturally competent professional practice of entry-level registered dietitians. Using Freire's notion of social justice and Vygotsky's constructivist theory as the conceptual frameworks, the purpose of this study was to explore educators' instructional strategies that promoted cultural competence in nutrition and dietetics education. The research questions examined how educators described the instructional practices they employed to promote cultural competence in nutrition and dietetics education. Using a qualitative instrumental case study design, 9 educators responded to an open-ended questionnaire, as well as provided documents for analysis in the form of assignments. First-cycle data analysis was conducted using an initial coding protocol followed with a second-cycle phase using axial coding. The key themes for educators included the necessity of cultural competence in nutrition and dietetics instruction, and classroom and experiential learning activities engagement. The key conclusion was cultural competence is necessary to bridge the gap between student education and professional practice. The project study resulted in a position paper that recommended revising the local study site's curriculum to be based in cultural competence instruction through multiple modalities of collaborative and experiential learning activities. Positive social change will be present through enhancing nutrition and dietetics education to better better prepare students to be culturally competent professionals who provide improved health care to their patients.

Registered Dietitians (RDs) attribute the success of their careers to a variety of factors, including formal education, influential mentors, specific skill sets, flexibility, and even having a supportive spouse. RDs with strong management skills are increasingly in demand in order to coordinate nutrition care and services in a cost effective manner. Clinical Nutrition Managers (CNMs) specifically coordinate medical nutrition therapy across the continuum of patient care. To aid in the career development of CNMs, research is necessary to determine the factors that have positive and negative effects on their career paths. This study examined intrinsic and extrinsic factors that impact the career paths of CNMs in addition to perceived career satisfaction. A five-part online survey was disseminated to members of the Clinical Nutrition Management Dietetic Practice Group (CNM DPG). CNMs were also defined as RDs who coordinate medical nutrition therapy and who manage personnel, finances, or both. Results (n=146) of both quantitative and qualitative analyses identified key intrinsic factors that demonstrated a positive effect on CNMs’ career paths including self-motivation, communication skills, teamwork, and leadership skills. The study also examined CNMs’ perceptions about the extrinsic factors on their career paths. Support from upper-level management and administration was identified as a crucial factor in career advancement. Having support from family was shown to be a positive influence, while many CNMs also reported that family needs and expectations, unforeseen life circumstances, and the economic climate had limited their career paths. Social service motivation had a slightly positive influence on career paths. Perceptions about career satisfaction indicated that CNMs were moderately satisfied with overall career success but less satisfied with income and career ladders. This study serves as an important precursor to future research which could explore CNMs’ perceptions regarding pay equity as well as the intrinsic and extrinsic factors that are more critical at various junctures in their career paths. Results from the study also help to fill an existing gap in the dietetics and career path literature and will also assist the Academy of Nutrition and Dietetics and others in developing strategies to foster the career development of CNMs.

Full textAbstract:
To date, most research in the area of college women and eating disorders has only been conducted to determine the prevalence of eating disorders among selected college subgroups. Although such research is limited, particularly for those women that choose to join social sororities, it generally indicates that sorority women represent a subgroup with high instances of eating disorders and often presents a conflicting view of these women's eating patterns and beliefs regarding weight loss and food. The present study was designed to continue the investigation of sorority women and their eating patterns by conducting a longitudinal study, consisting of five assessments over the course of one academic year, to assess whether the sorority women who are engaging in maladaptive eating behaviors and thought processes had these problems before joining a sorority or developed them later on as a member of the sorority. Specifically, this study was designed to answer the following research questions: First, do sorority women and nonsorority women differ in regards to weight, self-objectification, eating beliefs, or eating disorder symptoms at the start of or throughout the study? Additionally, do these initial reported weights, self-objectification scores, eating beliefs, or eating disorder symptoms vary over time for either group? Finally, is sorority membership a factor in any of these changes? Participants completed self-report measures of weight, eating beliefs (EBQ), eating disorder symptoms (EDDS), and self-objectification (TSOQ). The effects of time were analyzed for sorority members and non-sorority members using a 2 (sorority membership: sorority vs. non-sorority) x 5 (time: August vs. September vs. November vs. February vs. April) repeated measures analysis of variance (ANOVA) approach for the all of the dependent variables. Additionally, the interactions of sorority membership were analyzed. Results indicated there were no significant differences for self-objectification or the eating beliefs subscales of stereotypes, superstitions, or science. However, significant findings were shown for weight, the salves eating belief subscale, and reported eating disorder symptoms across time. Results are discussed in regards to the overall lack of significant differences between the two groups.

Full textAbstract:
Information on nutrition and aging research in Brazil, Chile and Mexico was compiled. The questionnaire was adapted from one published by the United Nations Population Fund. The Pan American Health Organization (PAHO) provided the initial contact list. A search of online library databases was also done. Databases yielded a total of 149 journal articles, 21 books, 9 dissertations and 17 theses on nutrition and aging published between 1983 and 2000. The information showed that nutrition and aging is an area in the process of policy and program development and that aging is an important public health issue because of the current and projected growth of this population group. In line with the PAHO goal of improving the possibilities for healthy aging, this study may help strengthen the integration of multidisciplinary nutrition and aging research with public health policy.

Full textAbstract:
Television (TV) reaches more people than any other medium which makes it an important source of health information. Since TV ads often offer information obliquely, this study investigated implied health messages found in food and nutrition TV ads. The goals were to determine the proportion of food and nutrition ads among all TV advertising and to use content analysis to identify their implied messages and health claims.
A randomly selected sample of TV ads were collected over a 28-day period beginning May 8, 1987. The sample contained 3547 ads; 725 (20%) were food-related. All were analyzed. About 10% of food-related TV ads contained a health claim.
Twenty-five representative ads of the 725 food ads were also reviewed by 10 dietitians to test the reliability of the instrument. Although the dietitians agreed upon whether a health claim existed in a televised food ad, their agreement was poor when evaluating the accuracy of the claim.
The number of food-related ads dropped significantly on Saturday, but the number of alcohol ads rose sharply on Saturday and Sunday. Snack ads were shown more often on Thursday, but snack commercials were also numerous on Saturday morning and afternoon, as were cereal ads. Ads for snack foods accounted for the greatest proportion of ads (20%) while fast food accounted for only 7%. Alcohol constituted about 9% of all food and nutrition ads.

Full textAbstract:
Nutritional support for bone marrow transplant recipients is recognized as vital, yet little research has occured to determine the best method.
This study was designed to survey existing food and nutrition services in bone marrow transplant centers in the U.S. in order to determine similarities in the services provided among centers from which a model protocol could be established for such centers.
A survey instrument was developed and sent to all chief dietitians associated with BMT centers in the U.S, listed the International Bone Marrow registry, 1982. Items on the questionnaire included: background information on size and organization, nature of foodservice, and nutrition support services.
The research suggested that there was a trend away from sterile food service. Problems encountered in establishing the food and nutrition services included: availability of single-serve sterile foods, standardization of recipes, and palatability of autoclaved foods. Four centers switched from sterile diets to either low bacteria diets or modified house diets at some point in their operation. Patient related services of the registered dietitian were most concentrated on admission and during critical care monitoring. Near all respondents indicated a desire to form a network for developing standards for services provided.
Many differences between centers still remain which prevent the development of a model center.
