Abstract:

Acute tryptophan (trp) depletion, which purportedly decreases brain serotonin, lowers mood in normal males with a multigenerational family history of major affective disorder (FH+), but not in male controls. In the present study, the hypothesis that a mood lowering response to acute trp depletion may reflect a susceptibility to depression was investigated further. As both a family history of major affective disorder (MAD) and female sex are considered to be risk factors for depression, the effects of trp depletion on mood were investigated in control and FH+ women. The temporal stability of mood change to trp depletion, when rechallenged at least one month later, was also assessed in order to appraise its utility as a putative susceptibility marker. Subjects ingested a trp deficient amino acid mixture on two separate occasions and a balanced control mixture containing trp on another occasion. Compared to the balanced condition, control women exhibited a significant lowering of mood following the trp depletion, whereas in a previous study control men did not. The sex difference in the mood response to trp depletion among controls is consistent with the fact that women are at greater risk for depression than men. Unlike controls, FH+ women showed no lowering of mood, which suggests that serotonin may not be as important in the etiology of depression in these women. The mood response to trp depletion exhibited poor temporal stability, which does not support its use as a susceptibility marker of depression in normal subjects. Its utility as a putative phenotypic marker for MAD awaits further study in FH+ subjects who respond to trp depletion. (Abstract shortened by UMI.)

Abstract:

Genetically enhanced high-carotene Beta III hybrid carrot was compared to a commercial carrot cultivar, Nantes Careless, for carotene content and macronutrient composition. Beta III contained more than twice the total carotene content of Nantes Careless, with α-carotene/β-carotene ratios higher in Beta III. Total solids from protein, lipids, and carbohydrate were greater in Beta III than in Nantes Careless. Beta III contained about five times the amount of sucrose and one-fifth the amount of glucose and fructose than Nantes Careless or reported literature values. Comparison of the bioavailability of carotenes in Beta III and Nantes Careless to purified β-carotene and retinyl acetate standards was made using two bioassays: the liver storage, slope-ratio assay and a curative growth study. Beta III provided liver retinol stores equivalent to stores provided by Nantes Careless, β-carotene, and retinyl acetate at dosage 300 RE. At 600 RE, only retinyl acetate increased liver retinol storage with dose. Carotene sources did not increase liver retinol storage, presumably owing to the mechanisms that prevent carotene vitamin A toxicity. Growth study results indicated vitamin A potency of Beta III was not equivalent to that provided by retinyl acetate. Slopes of the growth response curves for Nantes Careless and β-carotene were not significantly different from retinyl acetate; the slope of the Beta III growth response curve was significantly different. All carotene sources were similar to retinyl acetate in the curvilinear response of the growth curves. The appropriate fit of the quadratic function to the growth response curves suggested 12 RE/d was greater than requirement. The differences in results of the two bioassays used to determine bioavailability of carotenes in Beta III may be explained by a number of factors. The utilization of β-carotene from Beta III may be affected by a-carotene or other carrot constituents for absorption or conversion to vitamin A, or both. Stored liver retinol may be a combination of retinol and a-retinol with reduced vitamin A activity. The growth assay may be more sensitive to external variables that cannot be controlled.

Abstract:

The effect of diets with various dietary fiber sources on the plasma lipids, liver cholesterol, the histology of the gastrointestinal tract, heart, liver and kidney and the fecal neutral steroid excretion was investigated in hamsters. 155, 9-11 wk old, male Golden-syrian hamsters were fed a purified basal hypercholesterolemic diet (0.1% cholesterol, 10% fat, 4% dietary fiber) for 5 wk to elevate plasma lipid levels. Based on wk 4 plasma total cholesterol (TC) levels hamsters with elevated levels were randomly assigned, 16 animals/group, into six groups for another 4 wk: control, oat bran, guar gum, cellulose, xylan and sacrifice. After 4 wk of the fiber diets (10% dietary fiber), the plasma TC levels were significantly lowered in the oat bran, guar gum and xylan groups (16%, 12% and 15%, respectively) (p<.05). They were also significantly lower than the control and cellulose groups. Plasma HDL-C concentrations tended to be lower in all the treatment groups, but was significantly decreased only in the guar gum group (12%) (p<.05). The combined plasma VLDL-C + LDL-C was significantly lowered by the oat bran, cellulose and xylan diets (38%, 40% and 34%, respectively) (p<.05). The liver cholesterol concentration increased significantly from 1 mg cholesterol/g liver to 4.1 mg cholesterol/g liver (p<.05) after 4 wk of the control diet; this was further increased significantly only in the cellulose group (5.6 mg cholesterol/g liver), while the other treatment groups showed no significant changes or differences compared to the control diet group (wk 4). The total fecal neutral steroid excretion was significantly (p<.05) higher in the oat bran group compared to the other treatment groups. No major differences were observed in the tissue histology of the animals in the different treatment groups. In the present study, it appeared that oat bran, guar gum and xylan were effective hypocholesterolemic agents; however, their mechanism of action is still not clear.

Abstract:

L’aliment utilisé en pisciculture est onéreux et impacte l’environnement. Améliorer l’efficacité alimentaire (EA) pour produire la même quantité de poisson en utilisant moins d’aliment est un objectif majeur pour rendre l’aquaculture plus durable. Cet objectif pourrait être atteint grâce à la sélection génétique, mais cela nécessite des méthodes de phénotypage individuel, et mesurer la prise alimentaire individuelle est complexe chez le poisson. Les deux meilleures méthodes, à l’heure actuelle, consistent soit à élever les poissons individuellement, soit à les marquer avec un tag externe pour les identifier visuellement au sein de petits groupes. Je me suis focalisé sur des questions d’importance critique en lien avec l’estimation de l’EA individuelle, chez deux espèces aquacoles majeures, le bar Européen Dicentrarchus labrax et le tilapia du Nile Oreochromis niloticus. J’ai démontré qu’estimer l’EA individuelle au stade juvénile chez le tilapia du Nil permettait de prédire l’EA sur l’ensemble du cycle de production. Ensuite, j’ai comparé les deux méthodes de phénotypage chez le tilapia du Nil, et observé qu’elles ne fournissent pas des estimations équivalentes. Enfin, j’ai aussi constaté que les poissons les plus efficaces à taux de rationnement restreint n’étaient pas les plus efficaces à satiété, chez les deux espèces.Les deux méthodes de phénotypage demeurent, cependant, fastidieuses. J’ai, en conséquence, cherché de potentiels critères de sélection indirecte qui soient plus faciles à mesurer. Chez le bar européen, il n’y avait pas de corrélation entre l’EA individuelle et le taux métabolique individuel (estimé par la consommation d’oxygène). Par ailleurs, j’ai résolu des problèmes d’ordre méthodologique afin d’implémenter l’analyse de la signature isotopique, grâce à l’échantillonnage non létal des écailles, en tant que critère de sélection indirecte.Pour conclure, sélectionner les poissons au stade juvénile semble fiable et permettra de réduire les coûts de sélection. La méthode de phénotypage de l’EA individuelle à utiliser pour faire de la sélection génétique dépend, cependant, de l’espèce. En particulier, la structure sociale de l’espèce doit être prise en compte dans le choix de la méthode la plus appropriée. En outre, les poissons devraient être phénotypés dans des conditions d’élevage et de nourrissage aussi proches que possible de celles en élevage commercial. Le taux métabolique pourrait être utilisable en tant que critère de sélection indirecte si couplé avec des mesures de l’excrétion d’ammoniac ou de la composition corporelle. Quant à l’analyse de la signature isotopique des écailles, elle est techniquement réalisable et nécessite d’être plus amplement étudiée
In finfish aquaculture, feed is expensive and has environmental impacts. Improving feed efficiency (FE) to produce the same amount of fish with less feed is a major objective for sustainable aquaculture. This can be achieved by selective breeding but this requires methods for individual phenotyping, and measuring individual feed intake (FI) is technically challenging for fishes. The two best methods, to date, are either to rear fish individually or to tag them externally so that they can be visually identified while reared in small groups.I investigated some important issues related to estimation of individual FE, on two major aquaculture species, European sea bass Dicentrarchus labrax and Nile tilapia Oreochromis niloticus. I demonstrated that estimating individual FE at juvenile stage in Nile tilapia was predictive of FE over the whole production cycle. Then, I compared the two phenotyping methods in Nile tilapia, to discover that they did not provide equivalent estimations. Finally, I also found that the most efficient fish at restricted feeding were not the most efficient at satiety, in both species.Both phenotyping methods remain, however, tedious. I therefore investigated potential indirect selection criteria that are easier to measure. In European sea bass, there was no correlation of individual FE with individual metabolic rate (as oxygen consumption). Furthermore, I addressed methodological issues for implementation of stable isotope analyses with non-lethal sampling of fish scales as an indirect selection criterion.To conclude, selecting fish at juvenile stage seems reliable and will cut selection costs. Phenotyping method for individual FE towards selective breeding depends, however, upon the species. In particular, species collective behaviour must be considered when choosing the most suitable method. Furthermore, fish should be phenotyped at holding conditions and feeding levels that are as close as possible to commercial practices. Metabolic rate might be useful as an indirect criterion if coupled with measures of ammonia excretion or body composition. Scale stable isotope analyses are technically feasible and require further investigation

Full text

Abstract:

Solute carriers (SLCs) constitute the largest family of membrane-bound transporter proteins in humans, and they convey transport of nutrients, ions, drugs and waste over cellular membranes via facilitative diffusion, co-transport or exchange. Several SLCs are associated with diseases and their location in membranes and specific substrate transport makes them excellent as drug targets. However, as 30 % of the 430 identified SLCs are still orphans, there are yet numerous opportunities to explain diseases and discover potential drug targets. Among the novel proteins are 29 atypical SLCs of major facilitator superfamily (MFS) type. These share evolutionary history with the remaining SLCs, but are orphans regarding expression, structure and/or function. They are not classified into any of the existing 52 SLC families. The overall aim in this thesis was to study the atypical SLCs with a focus on their phylogenetic clustering, evolutionary conservation, structure, protein expression in mouse brains and if and how their gene expressions were affected upon changed food intake. In Papers I-III, the focus was on specific proteins, MFSD5 and MFSD11 (Paper I), MFSD1 and MFSD3 (Paper II), and MFSD4A and MFSD9 (Paper III). They all shared neuronal expression, and their transcription levels were altered in several brain areas after subjecting mice to food deprivation or a high-fat diet. In Paper IV, the 29 atypical SLCs of MFS type were examined. They were divided into 15 families, based on phylogenetic analyses and sequence identities, to facilitate functional studies. Their sequence relationships with other SLCs were also established. Some of the proteins were found to be well conserved with orthologues down to nematodes and insects, whereas others emerged at first in vertebrates. The atypical SLCs of MFS type were predicted to have the common MFS structure, composed of 12 transmembrane segments. With single-cell RNA sequencing and in situ proximity ligation assay, co-expression of atypical SLCs was analysed to get a comprehensive understanding of how membrane-bound transporters interact. In conclusion, the atypical SLCs of MFS type are suggested to be novel SLC transporters, involved in maintaining nutrient homeostasis through substrate transport.

Abstract:

After our previous study revealed a positive correlation between a high number of nutrition classes and healthy dietary habits, we analyzed the impact of one nutrition class on dietary habits. The objective of this study was to examine the effectiveness of one introductory nutrition class in raising awareness of healthy dietary habits and inspiring healthy changes. Undergraduate students in NSC 170 were given pre-surveys the second week of class (n = 364) and post-surveys the last week of class (n = 281). Both pre- and post-surveys contained questions about demographic information, meal preparation, dietary habits, and dietary self-assessment. The pre-survey revealed a significant relationship between increased age and self-perception of an unhealthy diet (p = 0.066), a significant decrease in fast food meals with age (p = 0.018), and increased fruit and vegetable consumption with nutrition majors. The post-survey revealed a significant relationship between increased academic status and self-perception of a healthy diet (p = 0.053) and a significant relationship between weight loss and self-perception of a healthy diet (p = 0.0125). A comparison of pre- and post-surveys revealed a decrease in the number of fast food meals in juniors and a significant increase in vegetables among nutrition majors.

Abstract:

The purpose of this study was to compare the level of basic nutrition knowledge between future nutrition professionals, health professionals, and non-health professionals. Specifically, this study assessed and compared basic nutrition knowledge of nutrition, health-related, and non-health related undergraduate majors enrolled in an introductory nutrition course.

Participants for this study were recruited through convenience sampling from an introductory undergraduate nutrition class. An online basic nutrition knowledge exam was used to measure nutrition knowledge. Independent one-way ANOVA demonstrated there was no statistically significant difference in basic nutrition knowledge between nutrition, health-related, and non-health related undergraduate majors. Post-hoc analysis revealed there was no significant difference of basic nutrition knowledge between health-related majors and non-health related majors, and there was a significant difference in basic nutrition knowledge between nutrition majors and health-related majors as well as between nutrition majors and non-health related majors. Thus, the results demonstrate there was a statistically significant difference in basic nutrition knowledge between nutrition students, and either health-related, and non-health related undergraduate majors.

Una de las preocupaciones sanitarias para esta población, es la valoración y la resolución de la malnutrición, hoy considerada como uno de los grandes síndromes geriátricos, Sin existir un "gold standard" que permita esta valoración, el Mini Nutritional Assessment (MNA) parece ser un instrumento que ha demostrado tener una gran aceptación en la comunidad científica por ser sencillo de aplicar, por no requerir exámenes de laboratorio y a pesar de ello tener una adecuada correlación con los marcadores bioquímicos del estado nutricional.

Basándonos en estos antecedentes, nosotros nos propusimos realizar un estudio que permitiera 1) Valorar el estado nutricional mediante la escala MNA de los usuarios de centros asistenciales de la ciudad de Lleida; 2) Establecer los factores que pueden estar asociados a riesgo de malnutrición o malnutrición establecida en dicha población y 3) Evaluar la utilidad clínica de la escala MNA como herramienta de cribado nutricional en los centros estudiados.

Para ello se diseñó un estudio de prevalencia sobre una muestra representativa de la población mayor procedente de distintos niveles asistenciales: centros sociosanitarios, hospital de agudos, residencia asistida y centro de atención primaria. En total fueron evaluados 398 sujetos, 46,2% hombres y 53,8% mujeres, con una media de edad de 77 años.
1) Según las categorías del MNA, observamos que el 22,6% de individuos estaban malnutridos, el 35,4% estaban en riesgo de malnutrición y el 42% estaban bien nutridos. La mayor prevalencia de malnutrición recayó en los centros sociosanitarios (larga y media estancia) y en el servicio de medicina interna del hospital de agudos seguidos por la residencia asistida y el servicio de cirugía del hospital de agudos. No se detectaron individuos malnutridos en el centro de atención primaria aunque si se observaron con riesgo de malnutrición. Todo ello confirma que a medida que aumenta el nivel de atención, el estado nutricional se deteriora. Así mismo pudimos comprobar que a medida que avanza la edad, las personas mayores tienen mayor riesgo de malnutrición o están mas mal nutridas.

2) Después de introducir en la regresión logística todos los factores que estaban asociados al estado nutricional insatisfactorio observamos que la perdida de peso, el vivir sin pareja, la discapacidad funcional, el deterioro cognitivo, el encontrarse subjetivamente solo, la patología pulmonar, los antecedentes de enfermedades del corazón y la presencia de vómitos, fueron los únicos factores independientes asociados a riesgo de malnutrición o malnutrición establecida.

3) Para finalizar, se confirma la considerable utilidad clínica de la escala MNA en su versión completa para la valoración nutricional de nuestra población mayor. Se confirma también la utilidad de la versión corta, aunque se necesitan en este sentido más estudios de investigación que refuercen esta hipótesis. El MNA es una herramienta práctica, rápida, sencilla y no invasiva que puede ser fácilmente administrada por cualquier profesional de la salud y que puede ayudar a entender y comparar diferentes grupos asistenciales desde la perspectiva nutricional.

Determina el aporte nutritivo de almuerzos de mayor consumo en la Empresa de Transportes “San Germán” y el estado nutricional antropométrico de sus conductores. Estudio descriptivo, observacional y transversal, realizado en la Empresa de Transportes San Germán, ubicada en la ciudad de Lima. La muestra estuvo conformada por 12 almuerzos de mayor consumo que se expenden en las cafeterías de la Empresa de Transportes San Germán y 35 conductores de la misma empresa; el muestreo fue no probabilístico, por conveniencia. Para determinar el aporte nutritivo de los almuerzos se utilizó el método de pesado directo de la ración servida y para determinar el estado nutricional de los transportistas se utilizó el método antropométrico. En el análisis de datos se emplearon medidas de dispersión y tendencia central y el paquete estadístico SPSS vs 15, Microsoft office 2007. El 89 % de los conductores presentaron sobrepeso y/u obesidad y el 97% presentó una circunferencia de cintura aumentada; lo cual aumenta el riesgo de padecer enfermedades cardiovasculares. Los almuerzos de mayor consumo analizados tuvieron una aporte promedio de 1,183.2 Kcal, que representa el 66.4% del requerimiento energético diario del transportista; de esas calorías el 14.7% provenía de proteínas, 27.9% de grasas y 56.9% de carbohidratos. La adecuación energética y de macronutrientes fue de 166.1% para kcal, 163.2% para proteínas, 186.2% grasas y 156.2% para carbohidratos. Los almuerzos de mayor consumo por los conductores son hipercalóricos, por ende, su adecuación porcentual de macronutrientes supera el 100% en todos los casos, lo cual explicaría por qué el gran porcentaje de los transportistas sujetos de estudio tiene sobrepeso, obesidad, y riesgo de padecer enfermedades cardiovasculares.

Abstract:

Os resultados do contraste leiteiro são uma ferramenta de gestão. Desequilíbrios nutricionais, metabólicos e infecciosos podem ser diagnosticados pela concentração de β-hidroxibutirato(BHB), azoto ureico(MUN), gordura, proteína, relação gordura/proteína e células somáticas(SCC) do leite. O objetivo é avaliar a variação destes parâmetros segundo fatores não-nutricionais e a inter-relação entre estes. Analisou-se 110461 amostras de 9523 vacas recolhidas mensalmente entre janeiro de 2015 e março de 2017 em 27 efetivos do sul de Portugal. Ajustou-se dois modelos lineares generalizados mistos para determinar os fatores associados à concentração de BHB e MUN serem superiores a 0,2mmol/L e 300mg/kg, respetivamente. Verificou-se um considerável efeito dos fatores não-nutricionais, embora variável consoante o fator e o parâmetro. Os modelos demonstraram que a produção de leite, fase e número de lactação e a relação gordura/proteína influenciam a concentração de BHB e MUN. A concentração de BHB também é influenciada pela SCC e gordura, a MUN pela proteína; MILK RECORDING: MONITORING TOOL FOR GREATER DAIRY FARMS EFFICIENCY ABSTRACT: Milk recording results are a management tool. Nutritional, metabolic and infectious disorders can be diagnosed by β-hydroxybutyrate(BHB), milk urea nitrogen(MUN), fat, protein, relation fat/protein and somatic cells concentration in milk. The objective is analyzed the variation of these parameters according to non-nutritional factors and the interrelation between them. This study analyzed 110,461 samples of 9,523 cows collected monthly from January 2015 to March 2017 from 27 herds of South of Portugal. Two generalized linear mixed regression models were constructed to determine non-nutritional factors associated with concentration of BHB and MUN greater than 0,2mmol/L and 300mg/kg, respectively. There was a considerable effect of non-nutritional factors, although variable according to factor and parameter. Models show that milk production, stage and number of lactation, and relation fat/protein influenced BHB and MUN concentration. BHB concentration is also influenced by somatic cells and milk fat, MUN concentration by milk protein.

Abstract:

Native Glycoprotein II (Phaseolin, G-II), the major 7S storage protein from Phaseolus vulgaris seeds, var. 'Processor' is known to be resistant to in vitro proteolysis by most endopeptidases. On sequential treatments with pepsin and a mixture of trypsin and chymotrypsin, the sub-unit polypeptides of G-II were split midchain. The fragments produced however, retained reactivity with the antibody raised against native G-II quantitatively. When measured by rocket immunoelectrophoresis, the extent of in vitro degradation of G-II by these endopeptidases was negligible. This procedure was used for monitoring the in vivo or in vitro degradation of G-II by gut enzymes other than trypsin or chymotrypsin. Diets containing 10% of a highly purified G-II preparation, did not support growth of rats adequately. Faecal N outputs were elevated and the true N digestibility based on Kjeldhal estimation was only 37%. In contrast, the true GII-N digestibility, based on immunological estimations, was high. It is suggested that G-II and/or its limited breakdown fragments (by trypsin or chymotrypsin) are stimulants of endogenous N secretion in the small intestine. The higher extent of the degradation of G-II in the small intestine of rats in vivo than that obtained by pure endopeptidases in vitro suggested the presence in this tissue of other enzymes capable to act upon and modify the structure of G-II, prior to the action of trypsin and chymotrypsin. These other modifying proteolytic enzymes render the G-II molecule more negatively charged and more susceptible to the subsequent action of trypsin and chymotrypsin. It is suggested that protease content and the ratio of the concentration of the GII-modifying protease(s) to that of trypsin and chymotrypsin may vary appreciably along the small intestine. Accordingly, the dependence of the degradation of G-II in vivo on the competition between all the enzymes capable of attacking it during its passage through the gut may explain the variability of GII breakdown in vivo.

Abstract:

La investigación tiene como objetivo analizar la función de los elementos visuales del gerontodiseño para comunicar información nutricional en los suplementos nutricionales dirigidos a los adultos mayores. La hipótesis propone que los elementos necesarios para la eficiente comunicación de una información nutricional completa son la tipografía, la paleta de colores, la gráfica visual y la forma del empaque. La metodología empleada consistió en un análisis documental, mediante la selección de dos marcas, Glucerna y Ensure, para el adulto mayor analizando el contenido de la información nutricional relacionado con los principales elementos del gerontodiseño. Adicionalmente, se realizó una encuesta a un grupo de 25 adultos mayores que consumen suplementos nutricionales, así como una entrevista a un experto que ha trabajado con marcas similares. Los principales resultados obtenidos, de acuerdo con los elementos del gerontodiseño, son que la tipografía presenta una fuente de letra san serif cumpliendo con la función de otorgar mayor legibilidad de la información; el contraste de color utilizado contribuye a diferenciar los elementos presentes; la imagen principal posee un movimiento orgánico para mostrar de manera más realista el producto a consumir y la forma de la estructura del empaque, al ser cilíndrica, favorece al adulto mayor a sostenerlo con firmeza y a proteger el contenido del interior. Se concluye que ambos productos toman en consideración los elementos del gerontodiseño en el diseño de su empaque, con lo que cumplen funciones esenciales para que el adulto mayor tenga la capacidad de poder visualizar la información que brinda el producto.
The research aims to analyze the role of visual elements of gerontodesign in communicating nutritional information in elder´s nutritional supplements. The hypothesis proposes that the necessary elements for an efficient communication for a complete nutritional information are typography, color palette, visual graphics and shape of the package. The methodology used for the investigation was a documentary analysis, where two brands of elder´s nutritional supplement (Glucerna and Ensure) were selected to observe the way the nutritional information is exposed in comparison to the main elements of gerontodesign. In addition, a survey was taken to group of 25 elders who consume nutritional supplements, plus an interview with an expert who has worked with similar brands. The main results obtained, according to the elements of the gerontodesign, is that the typography use in this products is a san serif font for a better reading of the information, the contrast of color is use to show the different elements present in the product, and the main image has an organic movement to show a more realistic way the product could be consumed and the shape of the structure of the package is cylindrical to favor the elderly to hold it better and to protect the content inside. It is concluded that both brands take into consideration the elements of gerontodesign for their packing design, because grown people may present certain difficulties that must be taken in consideration in the elaboration of the packaging.

Abstract:

ANTECEDENTES: El consumo de lácteos y su relación con el estado nutricional han sido poco investigados en estudios longitudinales en países en vías de desarrollo a lo largo de los años, su efecto protector sigue siendo de gran controversia hoy en día. OBJETIVO: Estimar la fuerza de asociación entre el consumo de lácteos y el estado nutricional (sobrepeso/obesidad) de los niños participantes de la cohorte mayor (2006-2013) del estudio “Niños del Milenio” en cuatro países en vías de desarrollo Etiopía, India, Perú y Vietnam. MÉTODOS: Análisis secundario de la cohorte mayor del estudio longitudinal “Young Lives”, considerando la exposición al consumo de lácteos desde la segunda hasta la cuarta ronda y el exceso de peso (sobrepeso/obesidad) en la cuarta ronda. RESULTADOS: Los análisis crudos de regresión de Poisson en la población total mostraron inicialmente asociación entre las variables de interés (RRc=2,44, IC 95%: 1,80-3,31, p<0,001), pero esta perdió significancia estadística después del análisis ajustado por sexo, edad, nivel socioeconómico, migración y consumo de frutas (RRa=1,03, IC 95%: 0,82-1,30, p>0,05). De igual forma, en los análisis realizados por país, tanto en modelo crudo como ajustado, no se evidenció asociación alguna (p>0,05). CONCLUSIÓN: No existe asociación entre el antecedente de consumo de lácteos en la niñez y el sobrepeso/obesidad en la adolescencia, en la población de la cohorte mayor del estudio “Niños del Milenio” (2006-2013) de los países participantes del estudio.
BACKGROUND: Dairy consumption and its relationship with nutritional status (overweight/obesity) have been little investigated in longitudinal researches in developing countries throughout the years and its protective effect is still highly controversial today. OBJECTIVE: Estimate the strength of association between dairy products consumption and nutritional status (overweight/obesity) of the participating children from the older cohort (2006-2013) of the “Young Lives” research in four developing countries (Ethiopia, India, Peru and Vietnam). METHODS: Secondary analysis of the older cohort from the “Youngs Lives” longitudinal research, considering the exposure to dairy consumption since the second to the fourth round, and the weight excess (overweight/obesity) in the fourth round. RESULTS: Crude analyzes of Poisson regression in total population initially showed association between interest variables (RRc=2,44, IC 95%: 1,80-3,31, p<0,001), but it lost statistical significance after the analysis adjusted by sex, age, socioeconomic level, migration and fruit consumption (RRa=1,03, IC 95%: 0,82-1,30, p>0,05). Similarly, in the analyzes carried out by country, both in the crude and adjusted models, no association was evidenced (p> 0,05). CONCLUSIONS: There is no association between the history of dairy consumption in childhood and overweight/obesity in adolescence, in the population from the older cohort of "Young Lives" study (2006-2013) of the participating countries.

Dissertation (M. Tech. (Food Service Management, Dept. of Hospitality and Tourism)) -- Vaal University of Technology
Very poor families, mostly in developing parts of the world, consume a monotonous staple diet out of need and are least likely to eat healthy diets. This study focussed on how the low income households in the urbanised informal settlement of Eatonside used available income to buy plant staples (situation analysis), the share of the food budget Rand allocated to this (investigative survey), as well as the extent of influence of low income, food prices, and locality on the buying behaviour. The aspects of where, how much, when and how low-income households purchased were examined in order to determine the purchasing patterns for plant staples. From the households surveyed, most (62,2%) received an income of less than R500.00/month. Household size affected food purchasing and varied according to the type of household head. Total food budget expenditure by male-headed households was 83,1 percent, 58,1 percent by female-headed households and 27,9 percent by de facto headed households. The total average share/portion of the food budget allocated to purchasing of plant staples was reported as R64.63 ±(R8.04). While male-headed households spent 15 percent of the total share/portion/month allocated to purchasing of plant staples, female-headed households spent 23,1 percent and de facto-headed households spent 21,1 percent. Total average expenditure allocated to plant staples was 58,1 percent for maize meal, 23,2 percent for rice, 4,6 percent for mabella, 3,9 percent for sugar beans, 3,7 percent for samp, 2,5 percent for split peas and 4 percent on various other plant staples. Price and quantity (63,6%) were main purchasing indicators. Less plant staples were purchased when prices were high and more when prices were low. Normally when prices of other food products are high, people buy more staples to survive. Most frequent purchases for maize meal was 12,5 kg (65%) once a month (41,7%) at an average price of R32.80 per unit from spaza shops. Plant staples were mostly purchased once a month (80,2%) at supermarkets (47%) or spaza shops (42%). The urbanised low income households of Eatonside were poor, leading to the allocation of a major component of the budget to food (plant staples). Purchasing patterns, plant staples, low-income households, Eatonside informal settlement.

The World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) used systematic literature reviews and the criteria for grading the evidence to comprehensively judge many epidemiological studies and experimental evidence, and then published “Food, Nutrition, Physical Activity, and the Prevention of Cancer: A Global Perspective” in 2007. It makes eight recommendations for cancer prevention, including ones to do with body fatness, physical activity, food and dietary supplements. The Panel recognized that recommendations are also made in relation to other diseases and took these into account in formulating those for cancer prevention. We, therefore have examine the association between compliance with WCRF/AICR recommendations and risks of diabetes mellitus, hypertension and hyperlipidemia incidences in 30-64 years Taiwanese. The databases used in the analyses were, firstly, the Nutrition and Health Survey in Taiwan (NAHSIT 1993-1996). Secondly, participants’ chronic diseases incidence status was obtained by linkage of NAHSIT to the National Health Insurance and, thirdly, to the National Death Certification database. Cox proportional- hazards models with person-years of follow-up as the time variable were used to calculate hazard ratios (HRs) and 95% confidence intervals (95% CI). During medians follow-ups of 13.0-13.5 years, the incidence densities of diabetes mellitus, hypertension and hyperlipidemia were 12.6, 29.1 and 13.4 per 1000 person-years. The combined effects of body mass index (BMI; kg/m2) and waist circumference were examined. After adjusting for potential confounders, the participants with a combination of BMI <24.0 and normal waist circumference (men <90 cm; women <80 cm), compared with those in the BMI ≥24.0 group with abnormal waist circumference (men ≥90 cm; women ≥80 cm) had lower risk of diabetes mellitus (HR=0.22, 95% CI: 0.14-0.33), hypertension (HR=0.55, 95% CI: 0.47-0.64) and hyperlipidemia (HR=0.38, 95% CI: 0.21-0.69). After adjusting for potential confounders, a score for the WCRF/AICR recommendations (range: 0-17) was associated with a significant reduction in risk of diabetes mellitus, compared with the highest ( ≥12) group and the lowest ( ≤8) group (HR: 0.33; 95% CI: 0.14-0.82; p for trend=0.013). In conclusion, WCRF/AICR recommendations did not increase the risks for diabetes mellitus, hypertension or hyperlipidemia. Of eight recommendations, maintaining normal weight was the most significant factor for prevention of these chronic diseases. WCRF/AICR recommendations total scores ≥11 points were significantly associated with a reduction in risk of diabetes mellitus.

Abstract:

Dietitians are expected to deliver sound and scientifically objective advice to the general public, yet their personal beliefs and behaviors could influence delivery of nutrition care. Increased understanding of the personal attitudes and behaviors of dietitians concerning eating behavior and body image could help improve dietetic practice. Traditional nutrition education emphasizes cognitive eating, i.e., monitoring energy intake and comparing macronutrient intakes to the current acceptable ranges. Intuitive eating, however, promotes the release of cognitive eating in favor of greater attention to physiologic cues, or “body wisdom”. We hypothesized that nutrition students in a traditional curriculum would report eating less intuitively than non-nutrition majors. We surveyed 258 female undergraduate students (96 nutrition majors and 162 non-majors) at the University of Massachusetts Amherst. Using Mann-Whitney U tests, we assessed the differences between nutrition majors and non-majors in terms of: intuitive eating, as measured by the Intuitive Eating Scale-2 (IES-2); body mass index (BMI, kg/m2); magnitude of body dissatisfaction (actual weight – ideal weight); and dieting behavior. We also used non-parametric Spearman’s rho correlations and Chi-squared statistics to examine relationships between variables. A two-way between-groups analysis of variance was used to calculate statistical differences in intuitive eating scores between diet behavior and major. Contrary to our working hypothesis, we found that IES-2 scores were significantly higher in majors versus non-majors (p= 0.01) and significantly lower (pnormalor underweight BMI. These observations provide novel information indicating that nutrition undergraduate students, who have the intention of becoming registered dietitians, report that they eat more intuitively and have a lower degree of body dissatisfaction than do undergraduate students not majoring in nutrition. Additional research is needed to address issues related to body dissatisfaction and body weight.
