title: [Relative validity of dietary indicators from the Brazilian National School-Based Health Survey among adolescents in Rio de Janeiro, Brazil].
abstract: This study evaluated the relative validity of the dietary indicators from the questionnaire used in the Brazilian National School-Based Health Survey (PeNSE) in the city of Rio de Janeiro, Brazil. The sample included 174 students. The following indicators were evaluated: regular consumption (≥ 5 times a week) of markers for healthy eating, markers for unhealthy eating, and routine eating habits (having meals with parents or guardians (MEAL), having breakfast (breakfast), and eating while studying or watching TV. The results of the questionnaire were compared with three 24-hour recalls. For all the markers of healthy eating, there was no difference in the proportion of regular consumption when comparing the two methods. The rates detected by the questionnaire were higher for packaged snacks and crackers and lower for cold cuts and MEAL. The indicators for regular consumption of markers for healthy eating and that referring to BREAKFAST were those with the highest accuracy. The dietary indicators used by the PeNSE survey showed satisfactory validity.
