目的 系统评价国内足月单胎孕妇孕期体重过度增长（excessive gestational weight gain，EGWG）的发生率，为临床实践和基层孕期保健工作提供参考。 方法 计算机检索PubMed、Web of Sicence、EBSCO、Embase、The Cochrane Library、中国知网、万方、维普、SinoMed等中英文数据库，检索时限为建库至2023年11月。 结果 纳入文献36篇，共62 834例足月单胎妊娠孕妇，EGWG的发生率为37.0%。亚组分析显示，大专以下文化程度、从事脑力劳动、孕期缺乏规律运动、孕前体质量指数≥25、初产妇、患有妊娠期糖尿病或妊娠期高血压的孕妇，EGWE发生率更高（均 P ＜0.05）。Meta回归分析表明，发表时间、南方地区、队列研究可能是造成异质性的因素（ P ＜0.05）。 结论 EGWG问题日益严重，妇幼保健人员应采取积极措施，识别高危人群，预防由EGWG引起的不良妊娠结局。

Objective To systematically evaluate the incidence of excessive gestational weight gain（EGWG) in full-term single pregnant women in China,and provide reference for clinical practice and primary healthcare prenatal care services.Methods A computer search was conducted on PubMed，Web of Sicence，EBSCO，Embase，The Cochrane Library，CNKI，Wanfang，VIP，SinoMed and other Chinese and English databases，the search period is up to November 2023.Results A total of 62834 full-term singleton pregnancies were included in 36 literatures，and the incidence of EGWG was 37.0%.Subgroup analysis showed the incidence of EGWG was higher in women with less than junior college education，mental work，irregular exercise during pregnancy，pre-pregnancy BMI≥25，primipara，gestational diabetes and gestational hypertension（all P ＜0.05）.Meta-regression analysis showed that publication time,southern region and cohort study may be the sources of heterogeneity（ P ＜0.05）.Conclusions The problem of EGWG is prominent，maternal and child health care workers need to take active measures to screen high-risk groups to prevent adverse pregnancy outcomes caused by EGWG.
