Obsolescências da TV e obesidade infantil

Estudo liga comerciais de comida a obesidade em crianças: "Pesquisadores da Escola de Saúde Pública de Harvard (HSPH) e o Hospital Infantil de Boston descobriram que as crianças que passam mais tempo assistindo à televisão também comem mais dos alimentos altamente calóricos e de baixo valor nutritivo que são anunciados na TV. Estudos anteriores demonstraram que as crianças que assistem mais à televisão estão mais propensas a estar acima do peso, mas essa é a primeira vez que uma equipe de pesquisa encontrou evidências para um mecanismo que explica a relação. Os resultados do estudo aparecem na edição de abril da Archives of Pediatric and Adolescent Medicine: When Children Eat What They Watch (Wiecha and colleagues studied 548 students from 5 schools in Massachusetts and observed them for nearly 2 years. Each additional hour of television viewing was associated with 167 additional calories per day, with increases in consumption of foods commonly advertised on television.)
