项目摘要

Description (adapted from the investigator's abstract): Unhealthy weight control methods and body image concerns, which may predispose to clinical and subclinical eating disorders, are widespread among college students. The primary aim of this application is to determine if reducing eating disorders risk-factors (excessive weight/shape concerns and/or bingeing) in female college students reduces the incidence of these disorders. Secondary aims are to evaluate the long-term effects, of a moderated, interactive, multimedia intervention to: reduce potential risk factors for eating disorders, determine the importance of weight gain, evaluate the role of upsetting events, detect new onset of other psychiatric disorders or alcohol and drug abuse on precipitating subclinical/clinical eating disorders. Six hundred sixty students at high risk of developing eating disorders from 3 different colleges/universities will be selected for the project. Students will be selected as being at risk based on high scores on the weight concerns scale. High-risk students will then be randomized into a multimedia risk-reduction program or to no-intervention and followed for up to two-and-a-half years. We expect that 10 percent of the students in the high-risk untreated group will develop eating disorders in one year and that the intervention will reduce this rate by 50 percent (a 5 percent difference). The multimedia risk-reduction program was chosen for the intervention because it was proven effective in a series of pilot studies and can be provided to students at relatively low cost. The intervention is a structured 9-week program which includes sections on reducing body image and weight/shape concerns, the risks of eating disorders, and increasing healthy weight regulation practices. The program also includes weekly readings and writing assignments and participation in a moderated electronic discussion group. The program automatically monitors adherence. Quarterly booster sessions will be provided to help ensure maintenance of risk factor reduction. The primary outcome measure will be one-year incidence of eating disorders determined by a diagnostic interview. Secondary outcome measures will include weight concerns, eating disorder symptoms, body shape and eating disorder attitudes, distress and treatment seeking. Changes in BMI, the occurrence of major stressors and psychiatric events will also be assessed to determine their impact on the incidence of eating disorders. Incidence rates will be compared using a chi-square statistic. Survival analyses and other multivariate statistics will be used to examine secondary hypotheses and exploratory analyses. The application focuses on issues relevant to recently described NIMH priorities in prevention. Developing and evaluating interventions to reduce eating disorders in this high-risk population is of extreme public health importance.

描述（改编自调查员的摘要）：不健康的体重控制方法和身体图像问题，这可能易于临床和亚临床饮食失调，在大学生中广泛。这该应用的主要目的是确定是否减少饮食失调女性的风险因素（重量/形状过度关注和/或暴饮暴食）大学生降低了这些疾病的发病率。次要目标是评估温和的，互动，多媒体的长期效果干预至：减少饮食失调的潜在危险因素，确定体重增加的重要性，评估沮丧事件的作用，检测其他精神疾病或酒精和药物滥用的新发作沉淀亚临床/临床饮食失调。六百六十名学生有3种不同的饮食失调的高风险该项目将选择大学/大学。学生会根据体重量表的高分，被选为处于危险之中。然后，高风险的学生将被随机分为多媒体降低风险计划或不干预，最多随后两年半。我们预计未经治疗的高风险学生中有10％的学生将在一年内发展饮食失调，干预将减少速率比50％（差5％）。降低多媒体风险选择计划进行干预，因为它被证明在一系列试点研究，可以以相对较低的成本向学生提供。干预是一个结构化的9周计划，其中包括减少身体形象和体重/形状问题，饮食失调的风险，并增加健康体重调节实践。该程序还包括每周阅读和撰写作业，并参与调节电子讨论组。该程序会自动监视依从性。将提供季度助推器会议以帮助确保维持风险减少因素。主要结局指标将是一年的发病率饮食失调由诊断面试确定。次要结果措施将包括体重问题，饮食失调症状，身体形状和饮食失调的态度，苦难和寻求治疗。 BMI的变化，重大压力源和精神病事件的发生也将被评估为确定它们对饮食失调率的影响。发病率将使用卡方统计量进行比较。生存分析和其他多元统计将用于检查次要假设和探索性分析。该申请专注于与最近有关的问题描述了预防的NIMH优先事项。开发和评估减少这种高危人群中饮食失调的干预措施是极端的公共健康重要性。
