The aim of this systematic review and meta-analysis was to examine the contribution of cognitive behavioral therapy (CBT) to the implementation of lifestyle changes, considering health-related and behavioral outcomes. A systematic literature review was performed using multiple databases (PsycInfo, PubMed and MEDLINE). The inclusion criteria comprised randomised controlled trials of CBT for lifestyle changes in patients with obesity and/or type 2 diabetes. The quality of study reporting was assessed with the revised Cochrane Collaboration's risk of bias tool. A meta-analysis was conducted on studies with appropriate outcomes. Nine randomised controlled trials, with a total sample size of 902 participants, met the inclusion criteria. The meta-analysis has shown a medium, significant effect size of CBT interventions for weight loss and weight maintenance, and a low, non-significant effect size of CBT interventions for reducing glycated hemoglobin (HbA1c) levels. A separate, combined, meta-analysis for all nine calculated effect sizes has yielded a medium and significant overall effect size for the model. Our review of the studies about the effectiveness of CBT in implementing lifestyle changes has, in comparison to usual control groups, proven the efficacy of CBT interventions in implementing lifestyle changes, especially for weight loss and weight maintenance.
本系统评价和荟萃分析的目的是考察认知行为疗法（CBT）对生活方式改变的实施的贡献，同时考虑与健康相关的和行为的结果。使用多个数据库（PsycInfo、PubMed 和 MEDLINE）进行了系统的文献回顾。纳入标准包括针对肥胖和/或 2 型糖尿病患者生活方式改变的 CBT 的随机对照试验。使用修订后的 Cochrane 协作风险偏倚工具评估研究报告的质量。对具有适当结局的研究进行荟萃分析。符合纳入标准的共有 9 项随机对照试验，总样本量为 902 名参与者。荟萃分析显示 CBT 干预对减肥和体重维持有中等、显著的效果大小，而对降低糖化血红蛋白（HbA1c）水平的 CBT 干预有低、不显著的效果大小。对所有 9 个计算的效应大小进行的单独、合并荟萃分析得出了模型的中等和显著的总体效应大小。我们对 CBT 在实施生活方式改变方面的有效性的研究进行了综述，与常规对照组相比，证明了 CBT 干预在实施生活方式改变方面的疗效，尤其是在减肥和体重维持方面。
