To identify shared risk and protective factors for purging, binge eating, and overweight.
Prospective cohort study.
Population-based questionnaires of children and adolescents residing across the United States.
Girls (n = 6022) and boys (n = 4518), aged 11 to 17 years in 1998, in the ongoing Growing Up Today Study.
Putative risk and protective factors within the psychological, behavioral, and socioenvironmental domains.
Overweight, use of laxatives or purging (vomiting), and binge eating. Because of the low prevalence of purging, we did not examine shared factors for this behavior among boys.
In 1998, a total of 219 girls (3.7%) and 30 boys (0.7%) reported purging behaviors, 426 girls (7.1%) and 90 boys (2.0%) reported binge eating, and 1019 girls (17.4%) and 1040 boys (24.6%) were overweight. From 1999 through 2001, 331 girls (7.8%) initiated purging behaviors, 503 girls (11.8%) and 132 boys (4.5%) initiated binge eating behaviors, and 424 girls (10.0%) and 382 boys (13.6%) became overweight. Concern for weight was directly associated with all 3 weight-related problems among boys and girls. Among girls, dieting, parental weight-related teasing, and family meal frequency had a shared effect on the weight-related problems examined.
Factors within the psychological, behavioral, and socioenvironmental domains may have a shared effect on purging, binge eating, and overweight. Further research is needed to determine if an intervention designed to address these shared risk and protective factors is effective in simultaneously reducing these weight-related problems.
确定催吐、暴饮暴食和超重的共同风险因素及保护因素。
前瞻性队列研究。
基于美国各地儿童和青少年的人口调查问卷。
参与“今日成长研究”的1998年年龄在11至17岁的女孩（n = 6022）和男孩（n = 4518）。
心理、行为和社会环境领域的假定风险因素及保护因素。
超重、使用泻药或催吐（呕吐）以及暴饮暴食。由于催吐行为的发生率较低，我们未研究男孩中该行为的共同因素。
1998年，共有219名女孩（3.7%）和30名男孩（0.7%）报告有催吐行为，426名女孩（7.1%）和90名男孩（2.0%）报告有暴饮暴食行为，1019名女孩（17.4%）和1040名男孩（24.6%）超重。从1999年到2001年，331名女孩（7.8%）开始有催吐行为，503名女孩（11.8%）和132名男孩（4.5%）开始有暴饮暴食行为，424名女孩（10.0%）和382名男孩（13.6%）超重。对体重的关注与男孩和女孩的所有3种与体重相关的问题直接相关。在女孩中，节食、父母与体重相关的取笑以及家庭用餐频率对所研究的与体重相关的问题有共同影响。
心理、行为和社会环境领域的因素可能对催吐、暴饮暴食和超重有共同影响。需要进一步研究以确定旨在解决这些共同风险因素及保护因素的干预措施是否能有效同时减少这些与体重相关的问题。
