运动功能障碍是一种常见的，使人衰弱的症状在饮食失调（艾德）。我们在一个以人群为基础的青少年样本中研究了运动经历与艾德行为和认知之间的横向和纵向关联。青少年（n = 4，054）自我报告他们是否行使控制形状和重量（运动减肥; EWL），如果是这样，他们是否行使，即使在或受伤，以及是否运动干扰生活功能（驱动运动）在14岁时，允许划定三个运动为基础的组：无EWL，EWL和驱动运动。参与者还报告了14岁时的艾德认知沿着14岁和16岁时的其他艾德行为（禁食，泻药，暴饮暴食）。采用性别分层回归方法来研究14岁时这些运动类别与14岁和16岁时的艾德行为和认知之间的关系。横截面上，在驱动运动组，与无EWL组相比，一贯报告较高水平的艾德认知和行为，与那些在EWL组也报告较高水平的一些艾德认知和行为相对于无EWL组。在14岁时，EWL和驱动运动组的人也表现出在16岁时禁食（男孩和女孩）和净化（仅女孩）的可能性更高，相对于14岁时无EWL组的人。结果告知我们的理解EWL和驱动的运动和艾德行为在青春期的发展时间，并指向有针对性的预防EWL报告的年轻人的潜在效用。
Dysfunctional exercise is a common, debilitating symptom across eating disorders (ED). We examined the cross-sectional and longitudinal associations between experiences of exercise and ED behaviors and cognitions in an adolescent, population-based sample. Adolescents (n = 4,054) self-reported whether they exercised to control shape and weight (exercise for weight loss; EWL), and, if so, whether they exercised even when or injured, and whether exercise interfered with life functioning (driven exercise) at age 14 years, allowing delineation of three exercise-based groups: No-EWL, EWL, and driven exercise. Participants also reported ED cognitions at age 14 years along with other ED behaviors (fasting, purging, binge eating) at ages 14 and 16 years. Sex-stratified regression approaches were employed to examine relationships between these exercise categories at age 14 and ED behaviors and cognitions at ages 14 and 16. Cross-sectionally, those in the driven exercise group, as compared to the no-EWL group, consistently reported higher levels of ED cognitions and behaviors, with those in the EWL group also reporting higher levels of some ED cognitions and behaviors relative to the no-EWL group. Those in the EWL and driven exercise groups at age 14 also demonstrated a higher prospective likelihood of fasting (boys and girls) and purging (girls only) at age 16, relative to those in the no-EWL group at age 14. Results inform our understanding of EWL and driven exercise and the developmental timing of ED behaviors in adolescence and point towards the potential utility of targeted prevention for young people who report EWL.
