To examine correlates of dieting behavior in overweight and non-overweight youth.
Data came from Project EAT (Eating Among Teens), a study of eating and weight-related attitudes, behaviors, and psychosocial variables among 4746 adolescents in public schools. Logistic regression was used to compare dieters and non-dieters, and to examine interactions of dieting and overweight status.
Approximately one third (31.8%) of the sample was overweight. Dieting in the previous year was reported by 55.2% of girls and 25.9% of boys. Dieting was associated with similarly elevated rates of extreme weight control behaviors, body dissatisfaction, and depression in both the non-overweight and overweight groups for both boys and girls. Girls reporting dieting behavior in both the non-overweight and overweight groups had similarly elevated risk for cigarette use, alcohol use, and marijuana use.
The negative correlates of dieting are similarly common among teens of varying weight status. These data suggest that dieting may not be a preferred method of weight management, even for overweight adolescents. Regardless of weight status, dieting may be a marker for other unhealthy behaviors and depressed mood in adolescents.
研究超重和非超重青少年节食行为的相关因素。
数据来自“青少年饮食”（EAT）项目，该项目对公立学校4746名青少年的饮食、与体重相关的态度、行为及心理社会变量进行了研究。采用逻辑回归比较节食者和非节食者，并检验节食与超重状态的相互作用。
约三分之一（31.8%）的样本超重。去年报告节食的女孩占55.2%，男孩占25.9%。在非超重和超重组中，男孩和女孩的节食行为都与极端体重控制行为、身体不满及抑郁发生率的升高相似。在非超重和超重组中报告节食行为的女孩，吸烟、饮酒和使用大麻的风险同样升高。
节食的负面相关因素在不同体重状况的青少年中同样常见。这些数据表明，即使对超重青少年而言，节食可能也不是首选的体重管理方法。无论体重状况如何，节食可能是青少年其他不健康行为和情绪低落的一个标志。
