This study is aimed at the comparison between an individual and a group cognitive-behavioral program for the treatment of obesity.
Parallel series, prospective, 3-year study. A group program of 10 weekly sessions focused on lifestyle modification was compared with a similar, individual 10-session program. Fifty-seven patients were assigned to individual treatment, and 84 patients to the group program.
One hundred- forty-one obese female outpatients without binge eating disorder, aged 42.0+/-11.6 years (m+/-SD), with Body Mass Index (BMI) 37.3+/-5.2 kg/m(2).
BMI and waist circumference were measured at 0, 6, 12 and 36 months. Analysis was performed on an intention-to-treat basis.
Mean weight loss was superior with the group program at 6 months (2.0+/-3.9 vs 0.8+/-2.5 kg/m(2); p<0.05), while no difference between the two treatments was observed at 12 and 36 months. Mean waist circumference was significantly different at 6 months (group 97.4+/-2.5 vs individual 102.9+/-2.4, p<0.05), still remaining superior in the patients following individual treatment (100.2+/-5.0 vs 103.7+/-5.9) at 12 months, while no difference between the two treatments was observed at 36 months. The proportion of patients losing more than 5% of initial body weight with the group program (16.6, 15.5, and 38.1% at 6, 12, and 36 months, respectively) was not significantly different from that observed with individual treatment (5.3, 14.0, and 35.0%, respectively).
A group cognitive-behavioral program for the treatment of obesity is not inferior to a similar program applied in individual setting, and it may enhance weight loss (especially fat mass, according to the waist measurement) in the short term.
本研究旨在比较个体化认知行为疗法与团体认知行为疗法对肥胖症的治疗效果。
平行系列前瞻性3年研究。将一个为期10周、聚焦生活方式改变的团体项目与一个类似的、为期10节的个体化项目进行比较。57例患者被分配至个体化治疗组，84例患者被分配至团体项目组。
141例无暴饮暴食症的肥胖女性门诊患者，年龄42.0±11.6岁（均数±标准差），体重指数（BMI）为37.3±5.2kg/m²。
在0、6、12和36个月时测量BMI和腰围。分析采用意向性分析。
团体项目在6个月时平均体重减轻更显著（2.0±3.9 vs 0.8±2.5kg/m²；p<0.05），而在12个月和36个月时两种治疗方法之间未观察到差异。6个月时平均腰围有显著差异（团体组97.4±2.5 vs 个体化组102.9±2.4，p<0.05），12个月时个体化治疗组患者的腰围仍更高（100.2±5.0 vs 103.7±5.9），而36个月时两种治疗方法之间未观察到差异。团体项目组体重减轻超过初始体重5%的患者比例（6、12和36个月时分别为16.6%、15.5%和38.1%）与个体化治疗组（分别为5.3%、14.0%和35.0%）相比无显著差异。
团体认知行为疗法治疗肥胖症并不逊色于个体化治疗，且在短期内可能促进体重减轻（尤其是根据腰围测量的脂肪量）。
