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.
本研究评估了巴西里约热内卢市巴西全国学校健康调查（PeNSE）所使用问卷中的饮食指标的相对有效性。样本包括174名学生。评估了以下指标：健康饮食标志物的经常食用情况（每周≥5次）、不健康饮食标志物以及日常饮食习惯（与父母或监护人一起用餐（MEAL）、吃早餐（breakfast）以及在学习或看电视时进食）。将问卷结果与三次24小时饮食回顾进行了比较。对于所有健康饮食标志物，比较两种方法时，经常食用的比例没有差异。问卷检测到的包装零食和饼干的比例较高，而冷切肉和MEAL的比例较低。健康饮食标志物经常食用指标以及与早餐相关的指标准确性最高。PeNSE调查所使用的饮食指标显示出令人满意的有效性。
