目的：评价针对年轻女性饮食失调症状和不健康体重增加的选择性预防方案。方法：由于身体形象的担忧，这些结果的高风险女大学生（N = 398； M年龄= 18.4岁，SD = 0.6）被随机分配到基于健康体重组的4小时预防计划中，该计划促进饮食摄入和身体活动的逐步持续健康改善，或教育宣传册控制条件。结果：与对照组相比，干预参与者在测试后的身体不满和饮食失调症状显著减少，身体活动显著增加，在6个月的随访中，体重指数（BMI）和自我报告的节食显著减少。调节分析显示，那些最初症状升高和有减肥压力的人饮食失调症状明显减轻，那些最初饮食失调症状升高的人BMI明显减轻。结论：结果表明，这种干预既减少了饮食失调症状，也减少了不健康的体重增加，但建议应该改进它，以产生更强、更持久的效果，并且它可能对既有身体形象又有饮食失调的年轻女性有用。
Objective: Evaluate a selective prevention program targeting both eating disorder symptoms and unhealthy weight gain in young women. Method: Female college students at high-risk for these outcomes by virtue of body image concerns (N = 398; M age = 18.4 years, SD = 0.6) were randomized to the Healthy Weight group-based 4-hr prevention program, which promotes gradual lasting healthy improvements to dietary intake and physical activity, or an educational brochure control condition. Results: Compared to controls, intervention participants showed significantly greater reductions in body dissatisfaction and eating disorder symptoms, and greater increases in physical activity, at posttest and significantly greater reductions in body mass index (BMI) and self-reported dieting at 6-month follow-up. Moderator analyses revealed significantly greater reductions in eating disorder symptoms for those with initially elevated symptoms and pressure to be thin and significantly greater reductions in BMI for those with initially elevated eating disorder symptoms. Conclusions: Results indicate that this intervention reduced both eating disorder symptoms and unhealthy weight gain, but suggest it should be improved to produce stronger and more persistent effects, and that it may be useful to target young women with both body image and eating disturbances.
