目的:为了检查ACT对体重(体重指数和体重)的有效性,饮食行为(暴饮暴食,情绪化的饮食,外部饮食和节制饮食),和心理结果(生活质量[QoL],抑郁症,心理灵活性,和体重污名)在超重和肥胖的成年人中。
方法:七个电子数据库(CINAHL,EMBASE,PubMed,PsycInfoScopus,科克伦图书馆,和WebofScience)从开始到2022年6月17日进行了搜索。使用随机效应模型分析了13项研究和48项独特效应大小。使用加权平均差(WMD)和以Hedges\'g(g)表示的标准化平均差计算汇总效应估计值。异质性使用Q统计进行评估,并使用I2进行解释。
结果:发现ACT在改善BMI方面有效(k=6,WMD=-.50,95%CI=-.90;-.11,t=-3.25,p=.20,I2=.0%),心理灵活性和体重相关的污名。然而,发现体重无显著变化(k=4,WMD=-0.3395%CI=-1.53;0.87,t=-.88,p=.44,I2=.0%),暴饮暴食(k=4,g=-.34,95%CI=-1.31;0.62,t=-1.13,p=.34,I2=71.1%),情绪化饮食(k=6,g=-.20,95%CI=-0.54;0.15,t=-1.47,p=.20,I2=45.0%),外部进食(k=5,g=-.40,95%CI=0.96;0.16,t=-1.99,p=.12,I2=81.8%),克制进食(k=3,g=0.2295%CI=-0.57;1.01,t=1.19,p=0.36,I2=69.1%),QoL(k=3,g=0.01,95%CI=-1.51;1.52,t=.02,p=.99,I2=90.2%)和抑郁(k=3,g=-.55,95%CI=-1.78;0.67,t=-1.94,p=.19,I2=79.9%)。
结论:ACT可有效改善体重减轻,但需要更多的研究来确定其有效性以及各种成分影响体重相关结局的潜在机制。
方法:从现有实证研究的系统评价和荟萃分析中获得的证据。
OBJECTIVE: To examine the effectiveness of
ACT on weight (body mass index and body mass), eating behaviours (binge eating, emotional eating, external eating and restraint eating), and psychological outcomes (quality of life [QoL], depression, psychological flexibility, and weight stigma) among adults with overweight and obesity.
METHODS: Seven electronic databases (CINAHL, EMBASE, PubMed, PsycInfo Scopus, The Cochrane Library, and Web of Science) were searched from inception through 17 June 2022. 13 studies and 48 unique effect sizes were analyzed using random-effects models. Pooled effect estimates were calculated using weighted mean differences (WMD) and standardized mean differences expressed in Hedges\' g (g). Heterogeneity was assessed using Q-statistics and interpreted using I2.
RESULTS: ACT was found to be effective in improving weight loss in terms of BMI (k = 6, WMD = - .50, 95% CI = - .90; - .11, t = - 3.25, p = .20, I2 = .0%), psychological flexibility and weight-related stigma. However, non-significant changes were found for body mass (k = 4, WMD = - 0.33 95% CI = - 1.53; 0.87, t = - .88, p = .44, I2 = .0%), binge eating (k = 4, g = - .34, 95% CI = - 1.31; 0.62, t = - 1.13, p = .34, I2 = 71.1%), emotional eating (k = 6, g = - .20, 95% CI = - 0.54; 0.15, t = - 1.47, p = .20, I2 = 45.0%), external eating (k = 5, g = - .40, 95% CI = 0.96; 0.16, t = - 1.99, p = .12, I2 = 81.8%), restraint eating (k = 3, g = .22 95% CI = - 0.57; 1.01, t = 1.19, p = .36, I2 = 69.1%), QoL (k = 3, g = .01, 95% CI = - 1.51; 1.52, t = .02, p = .99, I2 = 90.2%) and depression (k = 3, g = - .55, 95% CI = - 1.78; 0.67, t = - 1.94, p = .19, I2 = 79.9%).
CONCLUSIONS: ACT could be effective in improving weight loss but more studies are needed to ascertain its effectiveness and the underlying mechanism by which the various components influence weight-related outcomes.
METHODS: Evidence obtained from a systematic review and meta-analysis of existing empirical studies.
