Child obesity continues to be a prevalent public health issue. This meta-analysis synthesized 17 studies investigating the association between levels of psychological stress experienced by mothers and the body mass index of their children. The overall standardized mean difference effect size was positive and significantly different from zero in cross-sectional d = 0.20 (k = 14, 95% confidence interval [CI]: 0.06, 0.34) and longitudinal studies d = 0.18 (k = 5, 95% CI: 0.00, 0.351) and had significant heterogeneity in both (cross-sectional, Q[13] = 193.00, P < 0.001; longitudinal, Q[4] = 29.46, P < 0.001). In longitudinal studies, effect sizes were larger when children also would have experienced the stressor, Q(6) = 4.68, P < 0.05, for toddlers than infants, Q(4) = 5.04, P < 0.05, and in higher quality studies, Q(4) = 14.58, P < 0.05. Results highlight the potential benefits of including a parent stress management component in childhood obesity prevention programmes.
儿童肥胖仍然是一个普遍的公共卫生问题。这项荟萃分析综合了17项研究，调查母亲所经历的心理压力水平与其子女体重指数之间的关联。在横断面研究中（d = 0.20，k = 14，95%置信区间[CI]：0.06，0.34）和纵向研究中（d = 0.18，k = 5，95%CI：0.00，0.351），总体标准化平均差效应量为正，且显著不同于零，两者均存在显著异质性（横断面，Q[13]=193.00，P < 0.001；纵向，Q[4]=29.46，P < 0.001）。在纵向研究中，当儿童也经历了压力源时，效应量更大，幼儿比婴儿的效应量更大（Q(6)=4.68，P < 0.05），在高质量研究中效应量也更大（Q(4)=14.58，P < 0.05）。结果突出了在儿童肥胖预防计划中纳入家长压力管理组成部分的潜在益处。
