“…117 In addition, programs that educate parents about limiting media use in general have already been shown to be highly effective. 8 123 Several food manufacturers have already indicated a willingness to implement such a ban voluntarily, 124,125 but it remains to be seen whether they will follow through. [126][127][128] For example, children's cereals remain considerably unhealthier than adult cereals; they contain 85% more sugar, 65% less fiber, and 60% more sodium.…”

“…However, most researchers now agree that the evidence linking excessive TV-viewing and obesity is persuasive. [7][8][9] There have been dozens of longitudinal and correlational studies documenting a connection. 9 An increasing number of these studies hold ethnicity and socioeconomic status-known to be key factors in obesity-constant and still reveal that TV-viewing is a significant con-tributor to obesity.…”

Obesity has become a worldwide public health problem. Considerable research has shown that the media contribute to the development of child and adolescent obesity, although the exact mechanism remains unclear. Screen time may displace more active pursuits, advertising of junk food and fast food increases children's requests for those particular foods and products, snacking increases while watching TV or movies, and late-night screen time may interfere with getting adequate amounts of sleep, which is a known risk factor for obesity. Sufficient evidence exists to warrant a ban on junk-food or fast-food advertising in children's TV programming. Pediatricians need to ask 2 questions about media use at every well-child or well-adolescent visit: (1) How much screen time is being spent per day? and (2) Is there a TV set or Internet connection in the child's bedroom?

Context: Sedentary behavior is implicated in youth and adult overweight and obesity. However, the relationship between sedentary behavior and weight status is often small or inconsistent with few studies controlling for confounding factors such as diet and physical activity. Diet has been hypothesized to co-vary with some sedentary behaviors. It is opportune, therefore, to review whether dietary intake is associated with sedentary behavior in young people and adults. This may allow for better interpretation of the diversity of findings concerning sedentary behavior and weight status.Evidence acquisition: Published English language studies were located from computerized and manual searches in early 2010. Included studies were observational studies assessing an association between at least one sedentary behavior and at least one aspect of dietary intake in children (<11 years), and/or adolescents (12-18 years), and/or adults (>18 years).Evidence synthesis: 53 studies (k), totaling 111 independent samples were eligible for this review. Sedentary behavior in children (k=19; independent samples=24), adolescents (k=26; independent samples=72), and adults (k=11; independent samples=14) appears to be clearly associated with elements of a less healthy diet including lower fruit and vegetable consumption, higher consumption of energy-dense snacks, drinks and fast foods, and higher total energy intake. Strength of associations were mainly in the range of small-to-moderate. Conclusions:The association drawn mainly from cross-sectional studies is that sedentary behavior, usually assessed as screen time and predominantly TV viewing, is associated with unhealthy dietary behaviors in children, adolescents and adults. Interventions need to be developed that target reductions in sedentary time to test whether diet also changes. ContextSedentary behavior is rapidly emerging as an important issue in public health. Researchers are now investigating the role of sedentary behavior in diverse health outcomes. Typically, researchers have defined 'sedentary' as not meeting a criterion level of physical activity.However, by sedentary behavior we are referring to very low levels of energy expenditure through sitting and lying. Excessive sitting time is essentially the main concern for sedentary behavior researchers. 1,2 Studies are now showing associations between sedentary behavior (usually assessed as screen-based behaviors such as TV and computer use), and a range of health outcomes, including all-cause mortality and cardiovascular disease, 3, 4 adverse metabolic profile, 5 and obesity. 6 However, relationships are not always consistent across age, gender or health outcomes. For example, while there has been a longstanding assumption that TV viewing in youth is associated with overweight and obesity, 7 a meta-analysis of mainly cross-sectional studies found that the strength of such an association was actually very small. 8 Moreover, a review of sedentary behavior intervention studies showed inconsistent weight loss for young people. 9 ...

“…Dados de um estudo global revelam que crianças comumente assistem a programas que não foram feitos especificamente para elas, e que, nos horários de maior audiência desse público, o número de propagandas de alimentos pouco saudáveis é ainda maior que durante o resto da programação 31 . A falta de controle dos pais sobre o tempo em que os filhos assistem à TV tem sido relacionada ao baixo nível educacional da mãe 34 e a hábitos alimentares pouco saudáveis 35 .…”

ObjetivoComparar hábitos alimentares e comportamento de consumo de crianças de diferentes níveis de renda familiar de Florianópolis (SC), Brasil, relacionando-os com o hábito de assistir à televisão. MétodosEstudo qualitativo com análise de conteúdo de manuscritos originados de 23 grupos focais, realizados em uma escola pública e uma escola particular de Florianópolis (SC), compostos por 111 estudantes de 7 a 10 anos. Para verificar a renda familiar dos estudantes, dados sobre a ocupação dos pais foram classificados pela Classificação Brasileira de Ocupações. Os estudantes da escola particular pertenciam a famílias de maior renda em relação aos da escola pública. ResultadosNas duas escolas, a maioria das crianças entrevistadas referiu assistir à televisão sempre que possível, sem sentir controle dos pais sobre esse hábito. Além disso, afirmaram ter dinheiro para gastos independentes e vontade de comprar os produtos anunciados nas propagandas de televisão. Estudantes da escola pública relataram ingerir e adquirir guloseimas mais frequentemente e ter maior liberdade para fazer compras do que os estudantes da escola particular, que revelaram sentir-se controlados pelos pais em relação aos seus hábitos alimentares e compras realizadas.
