To evaluate the efficacy of the Female Athlete Body project (FAB) in reducing eating disorder (ED) symptoms and risk factors.
This study was a community participatory three-site, two-arm, cluster randomized controlled trial (RCT). Female collegiate athletes (N = 481) were randomly assigned by team to the FAB intervention, a behavioral ED risk factor reduction program, or a waitlist control condition. Primary analyses examined 18-month effects for ED pathology. Secondary analyses examined risk factors and correlates (e.g., thin-ideal internalization, negative mood, Female Athlete Triad knowledge, and body mass index [BMI]).
Linear mixed effects models with team as a cluster level variable and study condition as a between-subjects variable revealed significantly reduced dietary restraint in FAB teams relative to control teams. FAB teams also reported significantly fewer objective and subjective binge episodes than control teams. Finally, FAB teams showed significantly lower thin-ideal internalization and increased BMI at 18-months. No other significant differences were found.
This RCT examined the effects of a short intervention on ED pathology and risk factors in female collegiate athletes through 18-month follow-up. This trial is one of only three trials with female athletes that have shown long-term reductions in any ED symptoms or produced positive effects on ED risk factors. The present study is the first to find such effects with athletes using a brief (i.e., 4 hr) intervention at 18-month follow-up. Although small effects were found, the current trial provides valuable lessons about future design and implementation of similar trials with athletes.

评估女性运动员身体项目（FAB）减少饮食失调（ED）症状和风险因素的效果。
本研究是一项社区参与的三地点、两臂、聚类随机对照试验（RCT）。女性大学生运动员（N=481）按团队随机分配到 FAB 干预组、行为 ED 风险因素减少计划组或候补对照组。主要分析考察了 18 个月时 ED 病理的影响。次要分析考察了风险因素和相关性（例如，瘦理想内化、负面情绪、女性运动员三联征知识和体重指数 [BMI]）。
以团队为聚类水平变量，以研究条件为组间变量的线性混合效应模型显示，与对照组相比，FAB 团队的饮食限制明显减少。FAB 团队报告的客观和主观暴食发作也明显少于对照组。最后，FAB 团队在 18 个月时表现出明显较低的瘦理想内化和更高的 BMI。没有发现其他显著差异。
这项 RCT 通过 18 个月的随访，检查了短期干预对女性大学生运动员 ED 病理和风险因素的影响。这项试验是仅有的三项针对女性运动员的试验之一，显示出任何 ED 症状的长期减少或对 ED 风险因素产生积极影响。本研究首次发现，在 18 个月的随访中，使用简短（即 4 小时）干预措施对运动员有这种效果。尽管效果较小，但目前的试验为未来类似运动员试验的设计和实施提供了有价值的经验教训。
