摘要目的 分析死胎与孕妇体质量指数的相关性.方法 检索PubMed、EMbase文献数据库中发表的死胎与孕妇体质量指数的相关性的研究文献,应用STATA12.0进行敏感性分析及发表偏倚分析,并进行荟萃分析.结果 共纳入体重超重与死胎危险性的文章17篇,结果显示,超重孕妇死胎发生率显著高于体重正常组(OR 1.30,95％ CI[1.26,1.35]);共纳入肥胖与死胎危险性的文章25篇,结果显示,肥胖孕妇死胎发生率显著高于体重正常组(OR 1.71,95％ CI[1.66,1.76]).结论 体重超重和肥胖能够增加死胎发生的危险性.

abstractsObjective To clarify the association of stillbirth with the maternal Body Mass Index (BMI).Method We performed a comprehensive search from PubMed and EMbase to identify studies pertaining to the association between stillbirth and BMI.The statistical software,STATA (version 12.0) was applied to investigate heterogeneity among individual studies and summarize the studies.Results Our analysis included a total of 17 articles that examined the effect of overweight on the risk of stillbirth.The association between overweight and the risk of stillbirth was statistically significant (OR 1.30,95％ CI:1.26-1.35);25 articles that examined the effect of obesity on the risk of stillbirth.The association between obesity and the risk of stillbirth was statistically significant (OR 1.71,95％ CI 1.66-1.76).Conclusion Overweight and obesity can increase the risk of stillbirth.
