RESUMO
RESUMEN La conducta alimentaria en escolares está dada por grandes cambios, en este periodo adquieren mayor relevancia los hábitos alimentarios que determinarán su alimentación futura. Objetivo: Comparar la conducta alimentaria en escolares de diferentes establecimientos educacionales según estado nutricional. Métodos: Estudio observacional transversal, se aplicó cuestionario de comportamiento de alimentación infantil a 270 madres/tutores de niños entre 6 a 8 años de colegios públicos, subvencionados y privados de Viña del Mar, Chile. Resultados: El 49,6% de los niños presentó mal- nutrición por exceso. Los niños con obesidad presentaron respuestas positivas a la ingesta alimentaria en situaciones de molestia, preocupación y enojo, no fueron exigentes al momento de introducir nuevos sabores y fueron rápidos para comer (p<0,05). Al diferenciar por establecimiento, sólo el colegio particular presenta diferencias entre los niños con distinto estado nutricional, tanto en dimensiones de sobre ingesta como de antiingesta (p <0,05). Conclusiones: Los escolares de 6 a 8 años no presentaron diferencias significativas en su conducta alimentaria, niños con obesidad se asociaron positivamente a conducta de proingesta. Los niños del colegio público mantuvieron la misma conducta alimentaria, independiente de su estado nutricional, evidenciando mayor riesgo a presentar malnutrición por exceso a futuro, a diferencia del colegio particular.
ABSTRACT Eating behavior in schoolchildren is marked by great changes. In this period, eating habits acquire greater relevance as they will determine future behaviors. Objective: To compare feeding behaviors among schoolchildren by school type and nutritional status. Methods: A cross-sectional observational study in which a child eating behavior questionnaire was applied to 270 mothers / guardians of children between 6 and 8 years from public, subsidized and private schools in Viña del Mar, Chile was conducted. Results: Nearly half (49.6%) of children had malnutrition due to excess. Children with obesity had positive responses to food intake in situations of discomfort, worry and anger, were not demanding when introduced to new flavors and were quick to eat (p <0.05). When comparing by establishment, differences between children by nutritional status were observed only in those attending private schools, in terms of excess-intake and anti-eating (p <0.05). Conclusions: Children from 6 to 8 years old did not present significant differences in their eating behavior, children with obesity reported pro-eating behavior. Children attending public schools maintained the same eating behavior, independent of their nutritional status, showing a higher risk of malnutrition due to excess in the future, unlike those attending private school.

The prevalence of non-transmissible chronic diseases such as obesity, dyslipidemia and type 2 diabetes, among others, have increased worldwide. One way to prevent and/or control them is through bioactive food compounds that can be incorporated as functional ingredients (IF). The IF isa compound IF: apple pomace, opuntia palette, tomato pomace and rice bran. Objective: Assess the functional ingredient (IF) for glycemic control in humans. Subjects and Methods: 48 Subjects, both sexes, aged between 40 and 60. Divided into three groups: non-obese (NO), obese (OB) and diabetic (DM) with 16 subjects per group. Subjects consumed 600 g daily of nonfat yogurt with artificial sweetener. 50 percent of the subjects in each group received yogurt with IF and 50 percent without IF for 44 days. Metabolic control of capillary blood glucose was performed weekly, of nutrition every week, as well as basal metabolic control, 22 and 44 with: fasting blood glucose, lipid profile, tolerance test to glucose with 2 point sampling and calculation of HOMA-IR. All analyses were performed at the Institute of Nutrition and Food Technology (INTA), University of Chile. The statistical analysis included measures of central tendency and dispersion. They compared the effect of the intervention vs control using the Mann-Whitney U test for independent samples and the Chi2 test for categorical variables. Results:15 subjects from the DM group, 16 from OB and 10 from NO completed the experiment. Significant differences were found between the intervention group and the placebo in the obese group, in the weight variation of the basal-22 days, 22-44 and basal-44 days with p = 0.007, p = 0.001 and p = 0.001respectively, and significant differences in the NO group between the placebo and intervention groups in the variation basal-22 days for HOMA-IR (p = 0.010) and 44 -22 days for LDL (p = 0.045). Conclusion: In this study no significant differences were found for subjects stratified into...
