To estimate the prevalence of disordered eating behaviors and the association with energy and nutrient intake and nutritional status in adolescents.
A school-based cross-sectional study was performed involving a probabilistic sample of 487 teenagers (aged 15-19 years) from public schools in the Metropolitan area of Rio de Janeiro, Brazil. The Eating Attitude Test and the Bulimic Investigatory Test Edinburgh questionnaires were applied to identify abnormal eating patterns and unusual dietary patterns, respectively. Nutritional status was defined by sex- and age-specific body mass index cutoffs. Energy and nutrient intake were assessed by a 3-day food record. The association between variables was assessed by the prevalence ratio and 95% confidence intervals, Pearson's Chi-square test, and linear regression.
The prevalence of abnormal eating patterns was 7.4% and that of unusual dietary patterns was 18.9%. Vitamin C intake was higher among girls with abnormal dietary patterns, with a consequent lower frequency of vitamin C deficiency when compared to those with normal dietary patterns. Calcium intake was lower in boys with unusual dietary pattern than in those without this behavior. Excess weight was associated with the presence of unusual dietary pattern in girls (PR: 2.4, 95% CI 1.6-3.5).
The prevalence of disordered eating behaviors was high, mainly in those who were overweight. It was associated with lower calcium intake in boys and with higher Vitamin C intake in girls.

评估青少年饮食行为紊乱的患病率及其与能量、营养素摄入和营养状况的关联。
开展了一项基于学校的横断面研究，对来自巴西里约热内卢大都市区公立学校的487名青少年（15 - 19岁）进行概率抽样。分别应用饮食态度测试和爱丁堡贪食症调查测试问卷来识别异常饮食模式和不寻常饮食模式。营养状况通过按性别和年龄划分的体重指数临界值来定义。通过3天的食物记录评估能量和营养素摄入。变量之间的关联通过患病率比和95%置信区间、Pearson卡方检验以及线性回归进行评估。
异常饮食模式的患病率为7.4%，不寻常饮食模式的患病率为18.9%。饮食模式异常的女孩维生素C摄入量较高，因此与饮食模式正常的女孩相比，维生素C缺乏的频率较低。饮食模式不寻常的男孩钙摄入量低于没有这种行为的男孩。超重与女孩不寻常饮食模式的存在相关（患病率比：2.4，95%置信区间1.6 - 3.5）。
饮食行为紊乱的患病率较高，主要见于超重者。它与男孩较低的钙摄入量以及女孩较高的维生素C摄入量有关。
