To determine the relationship between childhood overweight/obesity and early puberty in both boys and girls. Specifically, this is the first time to conduct a meta-analysis of the relationship between childhood overweight/obesity and early puberty in boys.
Relevant studies were identified from PubMed, Web of Science, and EMBASE searches. The exposure of interest was overweight/obesity in childhood. Childhood was defined internationally as the age range of 0-18 years. The overall risk estimates were pooled using random effects models. Subgroup and sensitivity analyses were performed to explore possible sources of heterogeneity and to assess the robustness of the results.
A total of 10 studies involving 13,338 girls and 12,796 boys were included. Results showed that childhood overweight/obesity were associated with a significantly higher risk of early puberty in girls [odds ratio (OR): 2.22, 95% CI: 1.65-2.99]. Although without statistical significance, a higher risk of early puberty was also found in boys who were overweight/obese in childhood (OR: 1.29, 95% CI: 0.98-1.70). Heterogeneity in the risk estimates of early puberty was partially explained by study design, sample size, follow-up duration, definitions of early puberty and confounders controlled. Sensitivity analyses validated the robustness of the findings.
Our findings showed that for girls the associate between overweight/obesity and early puberty is definite or strong whereas for males, such an association is possible, prompting that future studies need to further explore the possible relationship between overweight/obesity and early puberty in boys.

确定儿童超重/肥胖与男孩和女孩青春期提前之间的关系。具体而言，这是首次对儿童超重/肥胖与男孩青春期提前之间的关系进行荟萃分析。
通过检索PubMed、科学网和EMBASE数据库确定相关研究。感兴趣的暴露因素为儿童期超重/肥胖。国际上儿童期定义为0至18岁的年龄范围。使用随机效应模型汇总总体风险估计值。进行亚组分析和敏感性分析，以探索异质性的可能来源并评估结果的稳健性。
共纳入10项研究，涉及13338名女孩和12796名男孩。结果显示，儿童期超重/肥胖与女孩青春期提前风险显著升高相关[比值比（OR）：2.22，95%置信区间（CI）：1.65 - 2.99]。虽然无统计学意义，但在儿童期超重/肥胖的男孩中也发现青春期提前风险较高（OR：1.29，95%CI：0.98 - 1.70）。青春期提前风险估计值的异质性部分可由研究设计、样本量、随访时间、青春期提前的定义以及所控制的混杂因素来解释。敏感性分析验证了研究结果的稳健性。
我们的研究结果表明，超重/肥胖与女孩青春期提前之间的关联是确定的或很强，但对于男性，这种关联是可能的，这提示未来研究需要进一步探索超重/肥胖与男孩青春期提前之间的可能关系。
