项目摘要

Very little is known about how the prevalence of eating disorders (EDs) has changed across generations or the trajectory of EDs over the course of adult development. This study offers a unique opportunity to 1) examine ED point prevalence and mean scores on dimensional ED measures across 5 cohorts of college students randomly sampled from the same university population in 1982, 1992, 2002, 2012, and 2022, 2) examine the longitudinal course of eating pathology from late adolescence to midlife (18 to 62+ years), and 3) identify predictors of course focusing on factors unique to adulthood. This project will offer new insights into how generation impacts gender differences in EDs and how both gender and generation impact longitudinal trajectory. This project builds on a study initiated in 1982 and replicated with the addition of new cohorts and extended with follow-up of well-characterized, established cohorts every 10 years since its inception. In the spring of 2022, 1600 undergraduates (800 women and 800 men) will be randomly sampled to complete surveys of weight, height, body image disturbance, dieting, disordered eating behaviors, and EDs. In addition, participants who completed these assessments in college will be sought for 10-, 20-, 30-, and 40-year follow- up. We project collecting 20-year follow-up data in over 1,700 adults (>70% retention), including nearly 500 men and over 400 participants from ethnic/racial minority groups. These data will allow us to examine generation X age effects to determine whether course of eating pathology differs across Baby Boomers (1982 cohort), Generation X (1992 cohort), and Millennials (2002 cohort). The investigation will be conducted in two stages: a survey phase and an interview phase. The survey phase will replicate methods employed for data collection in all prior waves to ensure comparability of data. Surveys include detailed items about demographic background; height and weight; dieting, body image, and exercise; 5 scales of the Eating Disorders Inventory (Bulimia, Drive for Thinness, Maturity Fears, Perfectionism, and Interpersonal Distrust); and symptoms of anorexia nervosa, bulimia nervosa, binge-eating disorder, and permit DSM-5 ED diagnosis and diagnoses of their partial and subthreshold variants. In addition, beginning in the 3rd wave, surveys included the Eating Disorder Diagnostic Scale which is included as a core ED assessment for the NIMH. On the basis of self-report survey data, all subjects diagnosed with an ED and controls matched to these subjects on age, sex, race, and ethnicity 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, suicidality, comorbidity, and treatment history for a nonclinical sample, similar to their use in the 3rd wave, 20 years ago. The long-term objectives of this project are to evaluate whether we are making progress in reducing the public health burden associated with EDs, determine the adult developmental course of EDs, and identify predictors of ED trajectory that can be translated into targets for intervention, including what to modify, in whom, and when.
对于饮食失调 (ED) 的患病率在几代人或不同时期之间的变化,我们知之甚少。 ED 在成人发展过程中的轨迹。这项研究提供了一个独特的机会来 1) 检查 5 组大学生的 ED 点患病率和维度 ED 测量的平均分 1982 年、1992 年、2002 年、2012 年和 2022 年从同一大学人口中随机抽样,2) 检查 从青春期后期到中年(18 至 62 岁以上)饮食病理学的纵向过程,以及 3) 确定 预测因素当然关注成年期特有的因素。该项目将提供新的见解 代际影响 ED 中的性别差异以及性别和代际如何影响纵向 弹道。该项目以 1982 年启动的一项研究为基础,并通过增加新的队列和重复研究来重复 自成立以来,每 10 年对特征明确的既定队列进行一次随访。在 2022年春季,将随机抽取1600名本科生(800名女性和800名男性)来完成 对体重、身高、身体形象障碍、节食、饮食失调行为和 ED 的调查。此外, 在大学完成这些评估的参与者将被寻求 10、20、30 和 40 年的后续评估 向上。我们计划收集 1,700 多名成年人的 20 年随访数据(保留率 >70%),其中包括近 500 男性和 400 多名来自少数族裔/种族的参与者。这些数据将使我们能够检查 X 代年龄效应以确定婴儿潮一代的饮食病理过程是否不同(1982 群体)、X 一代(1992 年群体)和千禧一代(2002 年群体)。调查将分两期进行 阶段:调查阶段和访谈阶段。调查阶段将复制数据所采用的方法 收集所有先前的波浪,以确保数据的可比性。调查包括有关人口统计的详细项目 背景;身高和体重;节食、身体形象和锻炼;饮食失调量表的 5 个量表 (贪食症、追求瘦身、成熟恐惧、完美主义和人际不信任);和症状 神经性厌食症、神经性贪食症、暴食症,并允许 DSM-5 ED 诊断和诊断 它们的部分和亚阈值变体。此外,从第三波开始,调查包括饮食 疾病诊断量表,作为 NIMH 的核心 ED 评估。在自我报告的基础上 调查数据显示,所有被诊断患有 ED 的受试者以及在年龄、性别、种族和年龄方面与这些受试者相匹配的对照组 将招募不同种族的人参与研究的访谈阶段。访谈将确定 调查评估的有效性,并提供有关心理社会功能、自杀倾向、合并症和 非临床样本的治疗历史,类似于 20 年前第三波中的使用情况。长期来看 该项目的目标是评估我们在减轻公共卫生负担方面是否取得进展 与 ED 相关,确定 ED 的成人发育过程,并确定 ED 轨迹的预测因素 这可以转化为干预目标,包括修改内容、修改对象以及修改时间。
