Reprodutibilidade e validade relativa do Questionário de Frequência Alimentar do ELSA-Brasil

Avaliou-se a reprodutibilidade e a validade do Questionario de Frequencia Alimentar (QFA) utilizado no Estudo Longitudinal de Saude do Adulto (ELSA-Brasil). Foram aplicados tres registros alimentares e um QFA em dois momentos no periodo de um ano (n = 281). Valores de energia e nutrientes dos registros alimentares foram deatenuados e Log transformados. Para avaliacao da reprodutibilidade e validade foi aplicado o teste de correlacao intraclasse (CCI) e calculados percentuais de concordância do consumo de nutrientes apos categorizacao por tercis. Na avaliacao da reprodutibilidade, coeficientes de CCI variaram de 0,55-0,83 para proteina e vitamina E, respectivamente; na avaliacao da validade, variaram de 0,20-0,72 para selenio e calcio, respectivamente. Concordâncias exata e adjacente entre metodos variaram de 82,9% para vitamina E a 89% para lipidio e calcio (media = 86%). Foi encontrada uma discordância media de 13,6%. Conclui-se que o QFA ELSA-Brasil apresenta confiabilidade satisfatoria para todos nutrientes e validade relativa razoavel para energia, macronutrientes, calcio, potassio e vitaminas E e C.
