The effects of mindfulness-based interventions (MBIs) on anthropometrics remain obscure. This review quantitatively synthesizes the effects of MBIs on decreasing body mass index (BMI), waist circumference (WC), weight, and percent body fat (%BF).
Seven databases, including CINAHL Plus with Full Text, PubMed, PsycINFO, Cochrane, Web of Science Core Collection, Embase, and Sociological Abstracts were searched; studies with a comparison group were selected. Random-effects models were then applied to estimate the pooled effects (Hedge's g), while exploratory moderation analyses with mixed-effects models were performed to explore potential moderators of MBIs on anthropometrics.
The pooled effect size was -0.36 (p < .001) on BMI, -0.52 (p < .001) on WC, -1.20 (p < .004) on weight loss, and -0.43 (p = .389) on %BF. The long-term effects from baseline to follow-up and from post-intervention to follow-up were sustained on BMI (-0.37, p = .027; -.24, p = .065) and weight loss (-1.91, p = .027; -0.74, p = .011) respectively. For weight loss, adding mindful movement had greater effects than those without (-2.65 vs -0.39, p < .001).
Our findings support the short-term MBI effects on BMI reduction, WC, weight, and %BF, and long-term effects on reducing BMI and weight. Future efforts should focus on sustaining effects on reducing WC and %BF.
正念干预（MBI）对人体测量学的影响仍不清楚。本综述定量综合了 MBI 对降低体重指数（BMI）、腰围（WC）、体重和体脂百分比（%BF）的影响。
检索了 7 个数据库，包括 CINAHL Plus with Full Text、PubMed、PsycINFO、Cochrane、Web of Science Core Collection、Embase 和 Sociological Abstracts，选择了有对照组的研究。然后应用随机效应模型估计合并效应（Hedge's g），同时使用混合效应模型进行探索性调节分析，以探讨 MBI 对人体测量学的潜在调节因素。
MBI 对 BMI 的合并效应大小为-0.36（p<0.001），对 WC 的合并效应大小为-0.52（p<0.001），对体重减轻的合并效应大小为-1.20（p<0.004），对 %BF 的合并效应大小为-0.43（p=0.389）。从基线到随访，以及从干预后到随访的长期效果在 BMI 上是持续的（-0.37，p=0.027；-0.24，p=0.065）和体重减轻（-1.91，p=0.027；-0.74，p=0.011）。对于体重减轻，增加正念运动比不增加的效果更好（-2.65 比-0.39，p<0.001）。
我们的研究结果支持 MBI 对降低 BMI、WC、体重和 %BF 的短期效果，以及对降低 BMI 和体重的长期效果。未来的研究应侧重于维持对降低 WC 和 %BF 的效果。
