ABSTRACT
@#Introduction: Regular aerobic exercise and low-fat milk consumption can improve certain cognitive functions and reducing emotional distress. However, the impacts of combining these modalities are less explored. Thus, the present study examined the effects of combining aerobic exercise and low-fat milk intake among sedentary female students. Methods: Using a nonrandomized pretest – posttest with a control group research design, 85 sedentary females aged 16 years old were assigned into either milk (n = 21), exercise (n = 22), combined low fat milk and exercise (n = 23), or control (n = 19) groups. One serving of low-fat milk was provided to the students during each school day, and a 1-hour supervised step aerobics exercise was conducted twice per week for 3 months. Emotional distress and sustained attention were measured at baseline, 6th and 12th weeks after the intervention. A mixed factorial ANOVA was used to analyse the data. Results: The results revealed significantly less emotional distress in the combined (p < 0.01) and exercise groups (p < 0.05) compared with the control group after 12 weeks. Additionally, significant reductions were observed in the total time taken and errors of omission for both digits 6 and 9 of the Digit Vigilance Test in the combined group (p < 0.05, p < 0.001) compared with the control group. Conclusions: The results showed that low fat milk alone did not provide any additional benefits related to distress regulation, but the combination of exercise and low-fat milk contributed to improving sustained attention.

The scope of the article is to evaluate the research trends of the Brazilian School Food Program (PNAE), by analyzing the papers published in journals on the Brazilian Federal Agency for Support and Evaluation of Graduate Education (CAPES) website in the period from 2008 to 2013. It involved bibliographical research by means of qualitative analysis to detect the most relevant issues addressed and discussed by the program. Ten scientific articles related to the area were selected after reading the abstracts and research topics of the articles and by a search for the following key words: public policy, family farming, school food. Studies related to the PNAE and its impacts were also considered, due to the connection with the activities carried out in Brazilian public policy. The paper presents the issues analyzed and discussed most on the subject during the period under consideration. The conclusion reached is that the main research trends are characterized by the study of strategies for food and nutrition safety, analyzing the composition and acceptance of foods offered to students by an analysis of production, better living conditions and local development of rural producers.

The objective of this study was to assess the delivery of fruits with nutrition education in rural schools measuring its impact on food knowledge, food consumption and children nutritional status. A longitudinal quasi-experimental study of one year was carried out in an experimental group with delivery of fruits plus nutrition education, compared with a control group. Subjects were 784 school children (preschool to 8th grade) in 5 basic schools in María Pinto and 192 in the control group in Curacaví. Nutritional status, food knowledge, food consumption, the amount of fruit distributed and customer satisfaction were evaluated. Results showed that 85% of preschool to 2nd grade and 68.2% 3th to 8th grade children reported to consume fruit as a snack at least 3 times perweek. In children from 3th to 8th grade dairy consumption (more than 2 times per day) increased from 62% to 74%, respectively (p<0.01). Consumption of fruit more than 2 times per day increased to 34.9%, and legumes intake more than twice per week increased 37.7% to 51.7% (p<0.0001). In preschool from 57.6% to 76.2% and vegetables consumption more than 2 times per day increased from 26.8% to 2nd grade children there was a significant increase in healthy food knowledge in the period of the intervention (p<0.0001), while in children from 3th to 8th grade there was a significant improvement in consumption of fish and dairy food (p<0.0001). In the control group there were no changes either in food knowledge or in fruit consumption, and no changes in nutritional status were observed in both groups. In conclusion, the success of the program resides in the improvement of food knowledge and fruit consumption as a protective factor. To achieve an impact in nutritional status is necessary the long-term continuity of the program.
El objetivo de la presente investigación fue evaluar la entrega de fruta, con educación nutricional en escuelas básicas rurales midiendo su impacto en conocimiento, consumo y estado nutricional de los niños. Para ello se realizó un estudio cuasi-experimental, de seguimiento longitudinal de un año de duración en niños intervenidos con educación nutricional y entrega de frutas, comparados con un grupo control. La muestra fue de 784 niños de prekinder a 8° básico de 5 escuelas de María Pinto y 192 de una escuela control en Curacaví. Se evaluó el estado nutricional, consumo de alimentos seleccionados, conocimientos sobre alimentación saludable y consumo de la fruta entregada y satisfacción de usuarios. Resultados: el 85% de los niños de prekinder a 2° básico y el 68,2% de 3° a 8° básico reportaron consumir fruta de colación 3 días a la semana. En niños de 3° a 8° básico aumentó el consumo en 2 o más porciones al día de lácteos, de 62% a 74% (p<0,01). El consumo diario de 2 o más frutas aumentó de 57,6% a 76,2% y de 2 o más porciones de verduras de 26,8% a 34,9% y las legumbres 2 o más veces por semana aumentaron de 37,7% a 51,7% (p<0,0001). Hubo un aumento significativo en el conocimiento de una alimentación saludable entre el inicio y final (p<0,0001) en niños de prekinder a 2° básico; en los de 3° a 8° básico el cambio fue significativo en pescados y lácteos (p<0,0001). El grupo control no presentó cambios en el conocimiento ni consumo (p>0,1). No hubo cambios significativos en el estado nutricional del grupo intervenido ni del control. Se concluye que el programa fue exitoso ya que se cumplió el propósito de aumentar el conocimiento y consumo de fruta como un factor protector de la salud y que para lograr impacto en el estado nutricional se requiere darle continuidad en el tiempo.

Chile's School Feeding Program delivers approximately 215,000 and 1.3 million breakfast and lunch trays daily to preschool and school children attending public schools. In 2011 we carried out a study with the objective to determine Kcal provided and consumed from breakfast and lunch trays respectively, acceptance" of the preparations and assess if there was an association between K cal consumed and nutritional status. The sample included 199 5 y old children from 6 schools located in 3 low income districts of Santiago (2 per district). K cal consumed was determined by the difference in weight of each preparation from 429 and 1491 breakfast and lunch trays, respectively. Almost 50% of the children were overweight. 10.8% and 30% of the breakfast and lunch trays respectively provided less K cal than indicated, while in 50% of them, there was an excess. In 22.5% of breakfast and lunch trays added together, consumption exceeded the amount indicated. The correlation between consumption of the preparation and acceptance was good. Salads showed low acceptability. No relation was found between K cal consumed and nutritional status. This program should include a revision of the combination of food preparations and their correct portioning as a means of addressing the high prevalence of childhood obesity.
El Programa de Alimentación Escolar de Chile (PAE) entrega diariamente 215.000 raciones de desayuno y almuerzo a preescolares y 1.3 millones a escolares de escuelas públicas y subvencionadas del país. El año 2011 efectuamos un estudio cuyo objetivo fue determinar las Kcal aportadas y consumidas en el desayuno y almuerzo, determinar si las preparaciones les gustaban a los niños y verificar si habría una relación entre Kcal consumidas y estado nutricional. La muestra incluyó a 199 niños de 5 años de 6 escuelas de 3 comunas (2 por comuna) de nivel bajo de Santiago. Se determinaron las K cal consumidas por la técnica de pesaje por diferencia en 429 y 1491 bandejas de desayuno y almuerzo respectivamente. Cerca del 50% de los niños tenía sobrepeso. En 10,8% y 30% de las bandejas de desayuno y almuerzo respectivamente el aporte calórico fue inferior a lo indicado; en 50% fue superior. En 22,5 % de las bandejas de ambos servicios, el consumo fue superior a lo establecido. Hubo una buena correlación entre consumo de la preparación y si les gustó. Las ensaladas mostraron baja aceptabilidad. No hubo relación entre estado nutricional y el consumo de calorías. Frente a la alta prevalencia de obesidad, se recomienda revisar la combinación de preparaciones y el porcionamiento de éstas.
