Exercise addiction is associated with multiple adverse outcomes and can be classified as co-occurring with an eating disorder, or a primary condition with no indication of eating disorders. We conducted a meta-analysis exploring the prevalence of exercise addiction in adults with and without indicated eating disorders.
A systematic review of major databases and grey literature was undertaken from inception to 30/04/2019. Studies reporting prevalence of exercise addiction with and without indicated eating disorders in adults were identified. A random effect meta-analysis was undertaken, calculating odds ratios for exercise addiction with versus without indicated eating disorders.
Nine studies with a total sample of 2140 participants (mean age = 25.06; 70.6% female) were included. Within these, 1732 participants did not show indicated eating disorders (mean age = 26.4; 63.0% female) and 408 had indicated eating disorders (mean age = 23.46; 79.2% female). The odds ratio for exercise addiction in populations with versus without indicated eating disorders was 3.71 (95% CI 2.00-6.89; I = 81; p ≤ 0.001). Exercise addiction prevalence in both populations differed according to the measurement instrument used.
Exercise addiction occurs more than three and a half times as often as a comorbidity to an eating disorder than in people without an indicated eating disorder. The creation of a measurement tool able to identify exercise addiction risk in both populations would benefit researchers and practitioners by easily classifying samples.
运动成瘾与多种不良后果有关，可分为与饮食障碍共病，或为无饮食障碍指征的原发性疾病。我们进行了一项荟萃分析，探讨了有和无饮食障碍指征的成年人中运动成瘾的患病率。
从研究开始到 2019 年 4 月 30 日，对主要数据库和灰色文献进行了系统回顾。确定了报告有和无饮食障碍指征的成年人运动成瘾患病率的研究。采用随机效应荟萃分析，计算了有和无饮食障碍指征的运动成瘾的优势比。
共纳入了 9 项研究，总计 2140 名参与者（平均年龄 25.06 岁；70.6%为女性）。其中，1732 名参与者无饮食障碍指征（平均年龄 26.4 岁；63.0%为女性），408 名参与者有饮食障碍指征（平均年龄 23.46 岁；79.2%为女性）。有和无饮食障碍指征的人群中运动成瘾的优势比为 3.71（95%置信区间 2.00-6.89；I=81；p≤0.001）。两种人群中运动成瘾的患病率均因使用的测量工具而异。
运动成瘾作为饮食障碍的一种共病，其发生率是无饮食障碍指征人群的三倍以上。创建一种能够识别两种人群中运动成瘾风险的测量工具，将使研究人员和从业者受益，因为这样可以方便地对样本进行分类。
