Eating behaviors like emotional eating, external eating and restrained eating play an important role in weight gain and weight loss in the general population. Improvements in eating behavior are important for long-term weight. This has not yet been studied in women with Polycystic Ovary Syndrome (PCOS). The aim of this study is to examine if a three-component lifestyle intervention (LI) is effective for improving disordered eating behavior in women with PCOS.
Women diagnosed with PCOS (N = 183), with a body mass index (BMI) > 25 kg/m and trying to achieve a pregnancy were either assigned to 1 year of 20 group sessions of cognitive behavioral therapy (CBT) combined with nutritional advice and exercise with or without additional feedback through Short Message Service (SMS) or Care As Usual (CAU), which includes the advice to lose weight using publicly available services.
The Eating Disorder Examination Questionnaire (EDEQ) scores worsened in CAU (47.5%) and improved in the LI (4.2%) at 12 months. The difference between the LI and CAU was significant (P = 0.007) and resulted in a medium to large effect size (Cohen's d: - 0.72). No significant differences were observed in EDEQ scores between LI with SMS compared to LI without SMS (Cohen's d: 0.28; P = 0.399). Also, weight loss did not mediate the changes in eating behavior. An overall completion rate of 67/183 (36.6%) was observed.
A three-component CBT lifestyle program resulted in significant improvements in disordered eating behavior compared to CAU. Changes in disordered eating behavior are important for long-term weight loss and mental health.

诸如情绪化进食、外部进食和节制性进食等饮食行为在普通人群的体重增加和减轻中起着重要作用。饮食行为的改善对长期体重控制很重要。多囊卵巢综合征（PCOS）女性中尚未对此进行研究。本研究的目的是检验三成分生活方式干预（LI）对改善PCOS女性的饮食失调行为是否有效。
诊断为PCOS（N = 183）、体重指数（BMI）> 25 kg/m²且试图怀孕的女性，被分配到为期1年的20次小组认知行为疗法（CBT）课程，结合营养建议和运动，有或没有通过短信（SMS）提供的额外反馈，或常规护理（CAU），后者包括使用公开可用服务减肥的建议。
12个月时，常规护理组（CAU，47.5%）的饮食失调检查问卷（EDEQ）得分恶化，生活方式干预组（LI，4.2%）得分改善。LI组和CAU组之间的差异显著（P = 0.007），并产生了中等至较大的效应量（科恩d值：-0.72）。与无短信的LI组相比，有短信的LI组EDEQ得分无显著差异（科恩d值：0.28；P = 0.399）。此外，体重减轻并未介导饮食行为的变化。总体完成率为67/183（36.6%）。
与常规护理相比，三成分CBT生活方式项目在饮食失调行为方面有显著改善。饮食失调行为的改变对长期体重减轻和心理健康很重要。
