目的了解已知的饮食失调（ED）危险因素如何随着时间的推移而相互变化，可以为有效的干预目标提供信息。我们在24个月的时间里使用交叉滞后面板模型检验了体重/体型关注与共病症状（如抑郁情绪、焦虑）和行为（如酗酒）之间的短期（即1个月）纵向相互关系。研究对象为185名年龄在18-25岁、ED发病风险极高的女性，随机分为在线ED预防干预组和等候组。我们还测试了基于干预接收的关系是否不同。结果1个月的体重/体形关注显著预测下个月的抑郁情绪；1个月的抑郁情绪也能预测下个月的体重/体型问题，但效应量较小。同样，第一个月的体重/体型担忧显著预测了下一个月的焦虑，但反之则不成立。结果显示，体重/体型担忧与酗酒之间没有任何时间关系。体重/体型关注与合并症症状和行为之间的关系在接受干预后没有差异。结论：研究结果支持将干预重点放在减轻体重/体型上，而不是减少合并症，以获得有效的短期改变。证据水平I级，证据来自设计合理的随机对照试验。
PurposeUnderstanding how known eating disorder (ED) risk factors change in relating to one another over time may inform efficient intervention targets. We examined short-term (i.e., 1 month) reciprocal longitudinal relations between weight/shape concern and comorbid symptoms (i.e., depressed mood, anxiety) and behaviors (i.e., binge drinking) over the course of 24 months using cross-lagged panel models.MethodsParticipants were 185 women aged 18-25 years at very high risk for ED onset, randomized to an online ED preventive intervention or waitlist control. We also tested whether relations differed based on intervention receipt.ResultsWeight/shape concern in 1 month significantly predicted depressed mood the following month; depressed mood in 1 month also predicted weight/shape concern the following month, but the effect size was smaller. Likewise, weight/shape concern in 1 month significantly predicted anxiety the following month, but the reverse was not true. Results showed no temporal relations between weight/shape concern and binge drinking in either direction. Relations between weight/shape concern, and comorbid symptoms and behaviors did not differ based on intervention receipt.ConclusionsResults support focusing intervention on reducing weight/shape concern over reducing comorbid constructs for efficient short-term change.Level of evidenceLevel I, evidence obtained from a properly designed randomized controlled trial.
