Intervenção orientada a modificar práticas alimentares em adolescentes mexicanos
##plugins.themes.bootstrap3.article.details##
O objetivo desta pesquisa foi avaliar a efetividade de uma intervenção educacional para promover práticas de alimentação saudável em adolescentes entre 11 e 12 anos, sob um enfoque de aprendizagem ativo. Nesta intervenção participaram adolescentes que cursavam o primeiro ano numa escola secundaria pública de renda média. A efetividade da intervenção foi avaliada em termos da alteração favorável da atitude para as refeições saudáveis, a auto-eficácia para escolher e balançar alimentos e o acréscimo do risco para a saúde que uma dieta não saudável envolve. A análise estatística dos dados indicou uma alteração significativa na atitude e risco percebido após a intervenção; no que diz respeito da auto-eficácia, a partir da aplicação de um modelo markoviano foi estimado quanto deveria durar a intervenção para maior percentagem de adolescentes se perceberem como auto eficazes na seleção da sua alimentação. Estes achados sustentam a proposta de uma modificação dos programas governamentais, para a criação de um ambiente saudável nas escolas de ensino fundamental e melhorar as competências dos alunos para seguir uma dieta balanceada, sim quebrar os padrões socioculturais e hábitos alimentares das famílias.
