O objetivo deste trabalho foi identificar a influência da televisão no consumo alimentar e na obesidade em crianças e adolescentes. Realizou-se revisão sistemática nas bases MedLine, PubMed, SciELO-Brasil e Lilacs, capturando-se 73 artigos publicados entre 1997 e 2007. Definiu-se não analisar artigos com adultos ou pré-escolares, notas, comunicações, revisões, amostras de população específica (indígenas, por exemplo) e enferma (exceto obesidade), e estudos de intervenção, selecionando-se vinte artigos para análise. Em seis, dentre oito estudos brasileiros, observou-se associação significativa entre televisão e obesidade, e, em um destes, também se verificou associação positiva entre televisão e consumo alimentar. Nas investigações internacionais, observaram-se seis, dentre dez artigos, evidenciando associação entre televisão e obesidade, além de se identificar associação inversa entre televisão e tempo de atividade física. Em cinco artigos, do total de seis internacionais que investigaram o consumo alimentar, observou-se associação significativa entre televisão e ingestão alimentar, verificando-se que crianças e adolescentes que despendem maior tempo com a televisão tendem a ingerir menos frutas e verduras, e mais porções de salgadinhos, doces e bebidas com elevado teor de açúcar. A associação entre televisão e consumo alimentar foi evidente (85% dos artigos), e a associação com obesidade apareceu em 60% dos artigos. Ao identificar-se que o tempo em frente à TV associa-se à inadequação dos hábitos alimentares e à redução da atividade física, revela-se o hábito de assistir à televisão como um importante fator que pode propiciar a obesidade entre crianças e adolescentes.
Resumo O objetivo deste artigo é investigar associação entre a proveniência de lanches consumidos na escola, seu valor nutricional e o sobrepeso/obesidade. Estudo transversal com 3.930 escolares de 7-10 anos de idade, de Santa Catarina. O consumo alimentar na escola foi avaliado com R-24 horas ilustrado, e a origem dos lanches por entrevista estruturada. Refrigerantes e sucos artificiais, frituras, salgadinhos industrializados, lanches prontos, doces, guloseimas e biscoitos recheados foram classificados como “lanches de baixo valor nutricional”, enquanto frutas, sucos naturais, legumes, verduras e sopa de verduras foram os “lanches de alto valor nutricional”. Realizou-se regressão logística univariada e múltipla. O sobrepeso/obesidade se associou significativamente ao consumo de alimentos provenientes da cantina (OR = 1,34; IC = 1,07-1,68), na rede particular. Trazer alimentos de casa foi significativamente associado ao maior consumo de lanches de baixo valor nutricional, nas escolas públicas (OR = 1,56; IC = 1,32-1,83) e nas particulares (OR = 2,64; IC = 1,76-3,97). Os resultados apontam a necessidade de expansão de normativas que minimizem a disponibilidade de alimentos de baixo valor nutricional nas cantinas e que promovam educação nutricional envolvendo a comunidade escolar.
Among the causes of obesity, environmental factors have also been studied, in addition to genetic, social, psychological, and hormonal factors. The distribution of food outlets, facilitating or hindering food acquisition, can promote body weight control by encouraging healthier food habits. The objective of this study was to investigate associations between environmental availability and utilization of food outlets and overweight/obesity in 7 to 14-year-old schoolchildren in Florianópolis, in the South of Brazil. A logistic regression analysis identified a positive association between overweight/obesity in 2195 schoolchildren and the presence of restaurants in the vicinity of their homes (buffer = 400 meters). Being a member of a family that utilizes public markets/greengrocers was also positively associated with overweight/obesity in the sample investigated. Identifying the distribution of these establishments in the vicinity of the homes of schoolchildren in middle-income countries is an important element in understanding the role played by the food environment in weight gain in a variety of different settings.

Aim: To verify scientific and epidemiologic evidences of the hypothesis of association between birth weight and overweight/ obesity in childhood and adolescence based on a systematic review of the literature. Method: A systematic review was performed in the MedLine/Pubmed, Scielo-Brasil and Lilacs electronic bases.
Living closer to parks/playgrounds was associated with lower BMI and WC among schoolchildren from low-income families. Living closer to football pitches was associated with higher BMI and WC among these schoolchildren. Living at intermediate distances from beaches was associated with lower BMI among these schoolchildren.
CONTEXT AND OBJECTIVE: Being born heavier than 4 kg is associated with current overweight and obesity over the long term. The objective here was to ascertain whether birth weight was related to overweight or obese status, among 7 to 14-year-old schoolchildren, taking into consideration the possible interactions between socioeconomic factors and other biological variables. DESIGN AND SETTING: Retrospective cohort study on a probabilistic sample of 2,696 children and adolescents living in Florianópolis, Santa Catarina, Brazil. METHODS:The following data were collected: anthropometric (student's weight, height and age; and parents' weight and height), socioeconomic (family income, number of people in house and parental schooling level), birth weight and gestational age. Overweight and obesity were classified using percentiles of body mass index and triceps and subscapular skinfolds. The outcome variables were overweight and obesity and the main explanatory variables were birth weight and birth weight according to gestational age. The control variables were the parents' nutritional status, their schooling level and the per capita family income. Poisson multivariate regressions were carried out. RESULTS: Higher prevalence of high birth weight was observed among overweight male adolescents (PR = 1.14; 95% CI = 1.02-1.27; P = 0.03), but this was not observed among obese male adolescents. Low birth weight and being born small for gestational age were also not associated with the outcomes. Among overweight and obese children, birth weight was not significantly different from that of normal-weight children. CONCLUSION: No significant association between birth weight and obesity was observed. However, there was a weak but significant association between high birth weight and overweight, among male adolescents.RESUMO CONTEXTO E OBJETIVO: Nascer com peso > 4 kg se associa a sobrepeso e/ou obesidade em longo prazo. O objetivo foi verificar se o peso ao nascer foi um fator relacionado ao estado de sobrepeso ou obesidade atuais, em escolares de 7-14 anos, levando em consideração interações possíveis com fatores socioeconô-micos e outras variáveis biológicas. TIPO DE ESTUDO E LOCAL: Estudo coorte retrospectivo numa amostra probabilística de 2.696 crianças e adolescentes residentes em Florianópolis, Santa Catarina, Brasil. MÉTODOS: Coletaram-se dados antropométricos (peso, estatura e idade dos escolares, peso e estatura dos pais), socioeconômicos (renda familiar, número de pessoas na casa, escolaridade dos pais) e de peso ao nascer e idade gestacional. Sobrepeso e obesidade foram definidos utilizando-se os percentis de índice de massa corporal e as dobras cutâneas tricipital e subescapular. Sobrepeso e obesidade foram desfechos, e peso ao nascer e peso ao nascer/por idade gestacional foram variáveis explanatórias principais. As variáveis de controle foram: estado nutricional dos pais, seu nível de escolaridade e renda familiar per capita. Foram realizadas regressões de Poisson. RESULTADOS: Nos adolescentes do sexo masculi...
Objective To describe the purchase of family farm and organic foods by the Brazilian School Food Program in the municipalities of the state of Santa Catarina, Brazil. Methods This is an analytic and descriptive study conducted from 2010 to 2011. An electronic survey was sent to all 293 Santa Catarina municipalities. The Chi-square test investigated the association between the study variables. Results Between 2010 and 2011, the number of municipalities that purchased family farm foods increased by 36%, with a total of 96% of Santa Catarina municipalities buying family farming foods in 2011. Of the 96%, 70% complied with Article 14 of Law nº 11,947/2009, which determines that at least 30% of the funds provided by the National Fund for the Development of Education should be spent on family farm products, and 48% purchased organic foods. The South was the state region that most complied with Article 14 (85%; p=0.02). However, as municipality size increased, compliance with Article 14 decreased (p=0.04). The municipalities that had the most difficulties buying family farm and organic foods were those with the lowest Municipal Human Development Index and number of students. Conclusion Most Santa Catarina municipalities purchased family farm foods in 2011, and most municipalities that complied with Article 14 of Law nº 11,947/2009 were in the South state region. Finally, municipalities with low Municipal Human Development Index and number of students had the most difficulties buying family farm foods.
