对体育活动干预对儿童青少年自尊和自我概念的影响进行系统评价和荟萃分析，并通过荟萃回归分析确定调节变量。Meta分析和Meta回归。通过对电子数据库的全面检索，确定了相关研究。研究入选标准为：（1）干预应该是有监督的身体活动，（2）报告了足够的数据来估计身体活动干预对自尊或自我概念的合并效应量，（3）参与者的年龄范围从3岁到20岁，（4）包括对照组或比较组。对于每项研究，提取了研究设计、干预设计和参与者特征。使用R软件（3.1.3版）和Stata（12.0版）合成效应量并进行调节分析以确定调节因子。识别出25项随机对照试验（RCT）研究和13项非随机对照试验（non-RCT）研究，共包括2991例病例。在随机对照试验中发现，单独干预身体活动对一般自我结果有显着的积极影响（Hedges' g = 0.29，95%置信区间[CI]：0.14至0.45; p = 0.001），自我概念（Hedges' g = 0.49，95%CI：0.10 - 0.88，p = 0.014）和自我价值感（Hedges' g = 0.31，95%CI：0.13 - 0.49，p = 0.005）。在非随机对照试验中，以及在与其他策略相结合的身体活动干预研究中，单独进行身体活动干预对任何结局均无显著影响。荟萃回归分析显示，较高的治疗效果与RCT中的干预设置相关（β = 0.31，95%CI：0.07至0.55，p = 0.013）。单独进行身体活动的干预与儿童和青少年自我概念和自我价值的增加有关。与其他环境相比，以学校为基础和以体育馆为基础的干预有更强的关联。
To perform a systematic review and meta-analysis for the effects of physical activity intervention on self-esteem and self-concept in children and adolescents, and to identify moderator variables by meta-regression. A meta-analysis and meta-regression. Relevant studies were identified through a comprehensive search of electronic databases. Study inclusion criteria were: (1) intervention should be supervised physical activity, (2) reported sufficient data to estimate pooled effect sizes of physical activity intervention on self-esteem or self-concept, (3) participants’ ages ranged from 3 to 20 years, and (4) a control or comparison group was included. For each study, study design, intervention design and participant characteristics were extracted. R software (version 3.1.3) and Stata (version 12.0) were used to synthesize effect sizes and perform moderation analyses for determining moderators. Twenty-five randomized controlled trial (RCT) studies and 13 non-randomized controlled trial (non-RCT) studies including a total of 2991 cases were identified. Significant positive effects were found in RCTs for intervention of physical activity alone on general self outcomes (Hedges’ g = 0.29, 95% confidence interval [CI]: 0.14 to 0.45; p = 0.001), self-concept (Hedges’ g = 0.49, 95%CI: 0.10 to 0.88, p = 0.014) and self-worth (Hedges’ g = 0.31, 95%CI: 0.13 to 0.49, p = 0.005). There was no significant effect of intervention of physical activity alone on any outcomes in non-RCTs, as well as in studies with intervention of physical activity combined with other strategies. Meta-regression analysis revealed that higher treatment effects were associated with setting of intervention in RCTs (β = 0.31, 95%CI: 0.07 to 0.55, p = 0.013). Intervention of physical activity alone is associated with increased self-concept and self-worth in children and adolescents. And there is a stronger association with school-based and gymnasium-based intervention compared with other settings.
