Objective. Determine the relationship between dietary quality and body weight/composition in college women. Specific emphasis was made regarding adherence to current MyPyramid guidelines, fruit, vegetable and junk food consumption. Design/Participants. The study used a cross-sectional design. One hundred and sixty three women were recruited to participate in the study. All participants were university students (20.4 ± 1.6 y). Diet intake was measured using the Dietary History Questionnaire (DHQ) and the Healthy Eating Index (HEI) was calculated to assess diet quality. Body fat percentage was assessed using the Bod Pod and BMI was calculated using height and weight measurements. Physical activity was measured objectively using accelerometers over seven consecutive days. Results. There was no significant difference in BMI or body fat percentage across university year. There was no relationship between diet quality (as measured using the Healthy Eating Index) and percent body fat or BMI. The number of MyPyramid equivalents of fruit was negatively correlated to body fat percentage (r = -0.2, p ≤ 0,05) but not BMI (r = -0.093, p =0.26). The number of MyPyramid equivalents of dairy was also negatively related to both body fat percentage (r = -0.21, p ≤ 0.05) and BMI (r = -0.21, p ≤ 0.05). Percentage of calories from Non Nutrient Dense Foods (NNDF) was positively related to percent body fat ( r= 0.179, p = 0.029). For every 1-percentage increase in NNDF, there was a 0.12 percentage point increase in body fat. Conclusion. Increasing fruit, dairy, and vegetable intake, and reducing intake from Non Nutrient Dense Foods (NNDF) such as French fries, cookies, and candy, may have a beneficial influence on body composition in college women.

This thesis investigates how a tax and warning label on less healthy snack food products may affect consumer behaviour when the imposition of the tax is a source of consumer information. A survey that included choice experiments was implemented in supermarkets. Participants were asked to choose between high fat snacks, some displaying a stigmatizing warning label, and healthier snacks. Multinomial logit and latent class models exploring choice were estimated and a predictive hypothetical market was set up. Results show that the warning label had a negative price premium of about $4. The effect of price, though small, becomes even smaller as BMI increases. A fat tax for health is not recommended because it might not hit the target population, people were not very price sensitive, and it would likely be regressive. To encourage health, it appears to be more effective to display a warning label than to apply a tax. / Agricultural and Resource Economics

Existem evidências de que dietas compostas por níveis elevados de lipídeos e/ou car-boidratos contribuem para o desenvolvimento de doenças crônico-degenerativas e de déficit cognitivo. Entretanto, os mecanismos pelos quais a obesidade materna interfere na saúde da prole, especificamente no metabolismo e na memória de longo-prazo, ain-da são pouco claros. O objetivo deste trabalho foi investigar se a obesidade materna interfere no metabolismo e nos comportamentos relacionados à memória de longo-prazo de seus filhotes, e se há um efeito somatório com a exposição à dieta de cafete-ria no decorrer da vida da prole. Ratas foram alimentadas com dieta controle (CON) ou de cafeteria (CAF) desde o desmame até os 210 dias de vida, no desmame de sua pro-le. A partir do desmame, seus filhotes machos foram divididos em 4 grupos (CON-CON, CON-CAF, CAF-CON e CAF-CAF) para que todas as ninhadas ingerissem CON ou CAF, independentemente da dieta materna. As mães foram decapitadas no dia seguin-te ao desmame dos filhotes. Foi decapitada e analisada em tarefas comportamentais metade dos filhotes aos 30 dias de idade e, a outra metade, aos 120 dias. As mães CAF apresentaram maior peso corporal total e de tecido adiposo e maiores concentra-ções circulantes de colesterol total, insulina e leptina do que as mães CON. A ingestão calórica semanal dos filhotes que ingeriram CAF mostrou-se maior do que os que inge-riram CON, independentemente da dieta materna. As ninhadas apresentaram peso cor-poral igual no desmame e aos 30dias, porém aos 120dias, os filhotes que ingeriram CON-CAF tiveram aumento de peso em relação aos filhotes CON, independentemente da dieta materna destes. Porém, os filhotes CAF-CAF tiveram redução do peso corporal em relação aos CON-CAF na idade adulta. Aos 30 e 120 dias, os filhotes que ingeriram CAF apresentaram peso de tecido adiposo maior do que os que ingeriram CON, inde-pendentemente da dieta materna. Aos 30 e 120dias, a trigliceridemia e a colesterolemia estavam iguais entre os grupos, assim como a glicemia aos 30 dias. Porém, aos 120 dias, os filhotes que ingeriram CAF apresentaram hiperglicemia, assim como hiperlepti-nemia e hiperinsulinemia, independentemente da dieta materna. Aos 30 dias, todos os grupos que foram expostos à dieta de cafeteria em alguma etapa da vida apresentaram declínio no desempenho em uma ou nas duas tarefas relacionadas à memória de lon-go-prazo (Reconhecimento de objetos e Esquiva Inibitória step-down). Já aos 120 dias, o grupo CAF-CAF foi o único que mostrou piora no desempenho na tarefa de Reconhe-cimento de Objetos, e todos os grupos mostraram capacidade de aprendizado e memó-ria na tarefa de Esquiva Inibitória step-down. Esses dados sugerem que a dieta materna modula o peso corporal e comportamentos relacionados à memória de longo-prazo dos filhotes e que seus efeitos sofrem influência da dieta pós-natal da prole. Porém, novos estudos são necessários para elucidar os mecanismos envolvidos no desenvolvimento dessas alterações. / There is evidence that diets containing high levels of lipids and / or carbohydrates con-tribute to the development of chronic degenerative diseases and cognitive impairment. However, the mechanisms by which maternal obesity affects health of offspring, specifi-cally in metabolism and long-term memory, are still unclear. The aim of this study was to investigate whether maternal obesity interferes with the metabolism and behavior related to long-term memory of their offspring, and if there is a summation effect with exposure to the cafeteria diet during the life of the offspring. Rats were fed a control diet (CON) or cafeteria (CAF) from weaning to 210 days old at weaning of their offspring. After wean-ing, their male offspring were divided into 4 groups (CON-CON, CON-CAF, CAF and CAF-CON-CAF) for all litters ingest CON or CAF, irrespective of maternal diet. Mothers were decapitated on the day following weaning of pups. Was decapitated and analyzed in behavioral tasks half the pups at 30 days of age and the other half at 120 days. CAF mothers had higher total body weight and adipose tissue and increased circulating con-centrations of total cholesterol, insulin and leptin than mothers CON. The weekly caloric intake of pups that ingested CAF was higher than those who ate CON, regardless of maternal diet. Litters showed body weight equal to weaning and 30days, but the 120dias, puppies who ate CON-CAF had weight gain compared to CON offspring, re-gardless of maternal diet these. However, the pups CAF-CAF had reduced body weight compared to CON-CAF adulthood. At 30 and 120 days, the puppies that ingested CAF showed greater weight of adipose tissue than those who ate CON, irrespective of ma-ternal diet. At 30 and 120dias, blood triglyceride and cholesterol were similar between groups, as well as blood glucose levels at 30 days. However, at 120 days, the puppies that ingested CAF showed hyperglycemia, as hiperlepti-nemia and hyperinsulinemia, irrespective of maternal diet. At 30 days, all groups were exposed to the cafeteria diet at some stage of life show a decline in performance in one or both tasks related to long-term memory (Recognition of objects and Dodge inhibitory step-down). Already at 120 days, the group CAF-CAF was the one who showed deterioration in performance in the task of Object Recognition, and all groups showed learning ability and memory in the inhibitory avoidance task step down. These data suggest that maternal diet modulates body weight and behaviors related to long-term memory of the puppies and their effects are influenced by postnatal diet offspring. However, further studies are needed to eluci-date the mechanisms involved in the development of these changes.

The Educational Product is an alternative to work with high school students, with an interest in strengthening the critical and scientific sense, besides being able to guide them to the professional market and academic education. The raw material used in the development of the activities comes from electronic scrap as well as electrical and electronic devices that are not put into operation. Along with the activities, a theoretical support material is provided for the student, as an aid to interpretation of the results obtained in the experiments. The work was developed with students of the third year of High School, in total, twelve experimental activities divided into four teams were carried out by the students under the guidance of the teacher, which addressed topics related to electrical charges, electrodynamics and electromagnetism. According to the obtained results, which were "measured" by means of a diagnostic evaluation, made by the students in the first moment before the development of the experimental activities and another one after the activities, it was possible to verify an improvement in the learning of the physical concepts involved In the experiments. In addition, there was a greater awareness on the part of students about the correct use and disposal of waste from electronic equipment and the importance of teamwork. / Esse trabalho está voltado ao desenvolvimento de atividades experimentais, às metodologias que favoreçam o conhecimento e o sucesso no processo de ensino-aprendizagem na disciplina de Física. O Produto Educacional é uma alternativa para se trabalhar com alunos do ensino médio, com interesse em fortalecer o senso crítico e científico, além de poder orientá-los para o mercado profissional e o ensino acadêmico. A matéria-prima utilizada no desenvolvimento das atividades provém de sucatas eletrônicas, bem como de aparelhos elétrico-eletrônicos que não são colocados em funcionamento. Juntamente com as atividades, disponibiliza-se um material de apoio teórico para o aluno, como auxílio para interpretação dos resultados obtidos nos experimentos. O trabalho foi desenvolvido com alunos do terceiro ano do Ensino Médio, no total, doze atividades experimentais divididas em quatro equipes foram realizadas pelos discentes sob a orientação do professor, as quais abordaram tópicos referentes a cargas elétricas, eletrodinâmica e eletromagnetismo. De acordo com os resultados obtidos, os quais foram “medidos” por meio de uma avalição diagnóstica, feita pelos alunos no primeiro momento antes do desenvolvimento das atividades experimentais e outra logo após as atividades, foi possível verificar uma melhoria no aprendizado dos conceitos físicos envolvidos nos experimentos. Além disso, observou-se uma conscientização maior por parte dos alunos quanto ao uso e descarte correto de resíduos provenientes de equipamentos eletrônicos e a importância se se trabalhar em equipe.

Cette recherche s’intéresse à la question des représentations que les enfants construisent au sujet de l’alimentation dans une perspective épistémologique constructiviste, ancrée dans les traditions de la communication et de la psychologie sociale. Notre but a été de déterminer si les représentations de l’alimentation chez les enfants pouvaient être comprises en tant que représentations sociales, et si la construction de ces représentations variait selon l’âge et selon l’appartenance socioculturelle des enfants. Pour ce faire, nous avons analysé les discours sur l’alimentation des enfants de 7 à 12 ans issus de trois contextes culturels différents. Ainsi, nous avons comparé les représentations de l’alimentation construites par des enfants nés, élevés et éduqués en Roumanie et au Québec, ainsi que celles des enfants nés (ou élevés depuis un très bas âge) au Québec, mais provenant de familles d’immigrants roumains. La méthodologie de recherche a reflété une intégration instrumentale des perspectives issues de la psychologie sociale et de la communication, en étant dérivée de la logique naturelle et des théories sur les représentations sociales. Nos résultats suggèrent que les enfants construisent des représentations sociales de l'alimentation et que ces représentations progressent en complexité, tant du point de vue cognitif que moral, suivant l'âge, en subissant des processus de constructions similaires. De plus, il existerait des influences liées à l'appartenance socioculturelle sur le contenu et sur la complexité des représentations, dans ce sens que les différences et les ressemblances entre les groups socioculturels renvoient soit à des influences culturelles, soit à des influences en lien avec l'idéologie. En fonction des résultats obtenus, nous avons proposé des stratégies communicationnelles visant à accroître l’efficacité des programmes d’éducation à la nutrition. De point de vue théorique, notre recherche contribue au raffinement de la théorie des représentations sociales et du développement de l'enfant, ainsi qu'au développement d’un nouveau regard méthodologique sur cette problématique. / This research focuses on children’s representations of food and nutrition from a constructivist epistemological perspective based on an interdisciplinary approach integrating communication and social psychology. Our goal was to determine which representations of food and nutrition could be understood as social representations, and if children’s age and cultural background interfered with the development of those representations. The subjects were children aged 7 to 12 from three different cultural backgrounds - we compared representations of food and nutrition built by children born, raised and educated in Romania and Quebec, as well as children from families of Romanian immigrants born (or raised from a very young age) in Quebec. The research methodology integrated social psychology and communication perspectives, instrumentally derived from natural logic and theories on social representations. Results suggest that children build social representations of food and nutrition, and that these representations become progressively more complex, undergoing a similar developmental process, according to children’s age, both from a cognitive and moral viewpoint. Moreover, the research highlights that socio-cultural background influences on the representations content and complexity refer either to cultural or ideological influences with regards to the differences and similarities between socio-cultural groups. Furthermore, we proposed scenarios of communication strategies aiming to increase the effectiveness of nutritional education programs. Finally, the research provides contributions to theories of social representations and child development as well as to the development of new methods for the analysis of representations.
