The psychological effects of dieting and weight loss have been an area of controversy in obesity. As part of a large multicenter study involving 1944 obese subjects seeking treatment at Italian medical centers, we investigated the effects of weight loss on psychological distress and binge eating in 500 subjects remaining in continuous treatment at different centers with slightly different strategies (78.8% females; age: M=46.2 years, SD=10.8; BMI: M=37.3 kg/m(2), SD=5.6). At baseline and after 12 months all subjects were evaluated by the Symptom CheckList-90 Global Severity Index (SCL-GSI) and by the Binge Eating Scale (BES). In both males and females, weight loss was associated with improved psychometric testing. Changes in SCL-GSI were associated with changes in BMI (beta=0.13; t=2.85; p<0.005), after adjustment for age, gender, initial BMI and center variability. Similarly, BES changes were associated with BMI change (beta=0.15; t=3.21; p<0.001). We conclude that in subjects compliant to follow-up a successful management of obesity, not directly addressing psychological distress, is associated with a significant improvement of both psychological distress and binge eating, linearly related to the amount of weight loss, independently of treatment procedures.
节食和减肥对肥胖者的心理影响一直是一个有争议的领域。作为一项涉及 1944 名寻求意大利医疗中心治疗的肥胖患者的大型多中心研究的一部分，我们调查了 500 名患者的体重减轻对心理困扰和暴食的影响，这些患者在不同中心继续接受略有不同策略的治疗（女性占 78.8%；年龄：M=46.2 岁，SD=10.8；BMI：M=37.3kg/m(2)，SD=5.6）。在基线和 12 个月时，所有患者均接受症状清单 90 项全球严重程度指数（SCL-GSI）和暴食量表（BES）评估。在男性和女性中，体重减轻与心理测试的改善相关。SCL-GSI 的变化与 BMI 的变化相关（β=0.13；t=2.85；p<0.005），在调整年龄、性别、初始 BMI 和中心变异性后。同样，BES 的变化与 BMI 的变化相关（β=0.15；t=3.21；p<0.001）。我们得出结论，在符合随访要求的患者中，成功管理肥胖症，而不直接解决心理困扰，与心理困扰和暴食的显著改善相关，与体重减轻的量呈线性相关，独立于治疗程序。
