J Hum Growth Dev. 2016; 26(3): 360-367 INTRODUCTIONSedentary behaviour is defi ned as a set of activities with energy expenditure close to rest values, typically held in a sitting position, including activities such as watching television, using a computer, playing video games, talking on the phone, or talking with friends 1,2 . One of the most used criteria to estimate the time sitting watching television and in front of a computer or video game, considers those who spend two or more hours a day in front of such a device to be engaging in sedentary behaviour 3 . In recent years, use of the term "screen time" has emerged as a way to analyse this sedentary behaviour in studies with scholars, being defi ned as one of the dimensions of sedentary behaviour, held in front of a screen. This includes watching television, using a computer and playing video games (with the exception of interactive games and portable devices), when used in a seated position or lying down 2 . A study that estimated the prevalence of sedentary behaviour related to the screen time, conducted in 2005/2006, with data from 40 countries of Europe and of the United States, showed that 66% of male and 68% of Abstract:Introduction: Studies about screen time and its correlates are generally determined by the sum of the duration of several behaviours. Studies that analysed behaviours separately highlighted different correlates.

“…6,7 Paradoxically, advertising broadcast by the mass media encourages intake of foods of high energy density and low nutrient density, such as cookies, chips/crisps and fast-food snacks. [8][9][10] Adolescence is marked by deep biological, cognitive and psychosocial changes and the experiences at this stage of life, such as the beginning of sexual activity, possible introduction of risky health-related behavior, expansion of autonomy from the family 11,12 and greater exposure to the media 6 may influence self-assessment of body image, possibly causing weight dissatisfaction and harmful health-related behavior. 13 The ideal body varies according to sex among young people.…”

CONTEXT AND OBJECTIVE: The high prevalence of obesity has led to public policies for combating it. People with normal weight may gain greater awareness of this issue and change their perceptions of their weight. The aim of this study was to evaluate the prevalence of body weight dissatisfaction among normal-weight adolescents, according to demographic and socioeconomic variables, health-related behavior and morbidities. DESIGN AND SETTING: Population-based cross-sectional study that used data from a health survey conducted in the city of Campinas, São Paulo, in 2008. METHODS:The prevalence and prevalence ratios of weight dissatisfaction were estimated according to independent variables, by means of simple and multiple Poisson regression. RESULTS: 573 normal-weight adolescents aged 10 to 19 years (mean age 14.7 years) were analyzed. The prevalence of weight dissatisfaction was 43.7% (95% confidence interval, CI: 37.8-49.8). Higher prevalences of weight dissatisfaction were observed among females, individuals aged 15 to 19 years, those whose households had eight or more domestic appliances, former smokers, individuals who reported alcohol intake and those who had one or more chronic diseases. Lower prevalence of dissatisfaction was observed among adolescents living in substandard housing. Among the normal-weight adolescents, 26.1% wished to lose weight and 17.6% wished to gain weight. CONCLUSION:The results from this study indicate that even when weight is seen to be within the normal range, a high proportion of adolescents express dissatisfaction with their weight, especially females, older adolescents and those of higher socioeconomic level.

& Erica Daiuto3 RESUMO: Rótulo é toda e qualquer informação referente a um produto que esteja transcrita em sua embalagem. Para o consumidor é por meio das tabelas de informação nutricional contidas nos rótulos que se tem acesso a dados como quantidade e porcentagem dos nutrientes presentes nos alimentos. Através desse conhecimento, pode-se realizar escolhas alimentares mais saudáveis, mitigando os efeitos negativos referentes à má nutrição na população, principalmente entre as crianças, alvo mais crítico da incidência da obesidade. O objetivo desta pesquisa foi avaliar a adequação dos rótulos de alguns alimentos consumidos pelo público infantil, em relação à Ingestão Diária Recomendada (IDR) e verificar se os aspectos gerais dos mesmos estavam em acordo com a legislação brasileira vigente. Para esse estudo foram selecionados cinco produtos embalados, tipo petiscos: salgadinho de milho, salgadinho de amendoim, amendoim, snacks de batata e biscoito de polvilho. Os rótulos de diferentes marcas de cada petisco foram analisados por meio da Ficha de Avaliação de Rotulagem, elaborada com base nas RDC N° 259, de 20 de setembro de 2002 e RDC N° 360, de 23 de dezembro de 2003. A adequação nutricional dos nutrientes destes alimentos (carboidratos, proteínas, gordura total, gordura saturada, gordura trans, fibra alimentar e sódio) foi avaliada em relação à preconizada pela IDR para crianças de 4 a 8 anos de idade. Houve pequena porcentagem de erros nos rótulos dos alimentos analisados, cerca de 12%, sendo a presença de vocábulos que induzem os consumidores ao equívoco a irregularidade com maior predominância, presente em 25% dos rótulos. Outros itens em desacordo foram a incompleta especificação dos aditivos alimentares na lista de ingredientes e a ausência de instruções sobre a conservação dos alimentos após abertura das embalagens, ambos com percentual de ocorrência de 18,75%. O alto teor de sódio verificado na informação nutricional dos alimentos demonstra que deve-se mitigar o consumo destes produtos entre a população infantil. PALAVRAS-CHAVE: obesidade infantil, rótulos, adequação nutricional. Nutritional Evaluation And Compliance Labelling Of "Snacks" Consumed By Children To The Brazilian RegulationsABSTRACT: Label is every and any information regarding to a product that is transcribed in its package. For the consumer it is through the nutritional information tables contained in the labels that there is access to data such as quantity and percentage of nutrients contained in foods. Through this knowledge, it is possible to make healthier food choices, minimizing the negative effects related to poor nutrition in the population, especially among children, the most critical rate of obesity incidence. The aim of this study was to evaluate the appropriateness of the labels of some foods consumed by children in relation to the Recommended Daily Intake (RDI) and verify that the general aspects of the labels were in accordance with Brazilian regulations. Five products were selected like snacks, corn snacks, snacks, peanut, p...
