DESCRIPTION (provided by applicant): Very little is known concerning the secular and longitudinal trends associated with bulimic syndromes. This study offers a unique opportunity to 1) examine rates of bulimia nervosa (BN) and eating disorders not otherwise specified (EDNOS) across 1982, 1992, and 2002 in college students, 2) examine and compare the longitudinal courses of BN and EDNOS at 10- and 20-year follow-up, and 3) evaluate secular trends, longitudinal course, and prognostic utility of eating disorder-related variables such as weight, body image disturbance, dieting, and disordered eating behaviors. Thus, this investigation could provide much needed data for a significant source of psychiatric morbidity among young adult women. In the springs of 1982 and 1992, a total of 2400 Harvard undergraduates (1600 women and 800 men) were randomly sampled to participate in a study of weight, body image disturbance, dieting, disordered eating behaviors, and BN. In 1992, participants in the 1982 study were contacted to participate in a follow-up study. In the spring of 2002, this study proposes to collect data from a new cohort of undergraduates (800 women and 400 men) and to contact participants from the 1992 and 1982 cohorts (1189 women and 511 men) for 10- and 20-year follow-up evaluations, respectively. The investigation will be conducted in two phases: a survey phase and an interview phase. The survey phase will replicate methods employed for data collection in 1982 and 1992 in order to insure comparability of results. Surveys include items about demographic background, height and weight; concerns about dieting, body weight, and shape; 5 scales of the Eating Disorders Inventory (Buhrnia. Drive for Thinness, Maturity Fears, Perfectionism, and Interpersonal Distrust); and BN symptoms. In addition, surveys will include the Eating Disorder Diagnostic Scale for termination of DSM-IV symptoms of anorexia nervosa, BN, and binge eating disorder. On the basis of self-report survey data, all subjects diagnosed with BN or EDNOS and controls matched to these subjects on age, sex, race, ethnicity, and SES will be recruited for participation in the interview phase of the study. Interviews will establish the validity of survey assessments, as well as provide data on psychosocial function, comorbidity, and treatment history for a nonclinical sample of individuals with eating pathology. The long-term goals of this study are to capture the changing epidemiology of bulimic disorders; to evaluate the long-term correlates and consequences of bulimic syndromes that support meaningful distinctions between BN and its subthreshold forms; and to identify contributants to the development, maintenance, and outcome of BN.

描述(由申请人提供)：对以下方面知之甚少 与暴食症相关的长期和纵向趋势。本研究 提供了一个独特的机会来1)检查神经性暴食症(BN)和 1982年、1992年和2002年未指明的饮食失调(EDNOS) 大学生，2)BN和BN纵向课程的考察和比较 EDNOS在10年和20年的随访中，以及3)评估长期趋势， 进食障碍相关的纵向病程和预后作用 变量，如体重、身体形象障碍、节食和紊乱 进食行为。因此，这项调查可以为 年轻成年妇女精神疾病的重要来源。在 1982年和1992年春季，共有2400名哈佛本科生(1600名女性 和800名男性)被随机抽样参加了一项关于体重、身体 形象障碍、节食、饮食行为紊乱和BN。1992年， 我们联系了1982年研究的参与者，让他们参与后续研究 学习。在2002年春天，这项研究建议从一项新的 本科生队列(800名女性和400名男性)并联系参与者 来自1992年和1982年的队列(1189名女性和511名男性)，为期10年和20年 分别进行后续评价。调查将分两个阶段进行 阶段：调查阶段和访谈阶段。调查阶段将复制 1982年和1992年采用的数据收集方法，以确保 结果的可比性。调查包括有关人口统计背景、 身高和体重；对节食、体重和体型的关注；5个等级 饮食障碍调查表(Buhrnia.追求苗条，成熟恐惧， 完美主义和人际不信任)；以及BN症状。此外, 调查将包括饮食障碍诊断量表，用于终止 DSM-IV神经性厌食症、BN和暴饮暴食障碍症状。论 根据自我报告调查数据，所有诊断为BN或EDNOS的受试者 在年龄、性别、种族、种族和SES方面与这些受试者匹配的对照组将 被招募参加研究的面试阶段。采访 将确定调查评估的有效性，并提供关于 非临床患者的心理社会功能、合并症和治疗史 患有进食病理的个体样本。这项研究的长期目标 是捕捉暴食症不断变化的流行病学；评估 支持暴食症综合征的长期相关性和后果 BN及其亚阈值形式之间的有意义的区别；并识别 对国阵的发展、维护和结果作出贡献的人。
