【摘要】：目的探讨孕前体重指数及孕期体重增加与巨大儿的发生率之间的关系。方法回顾性的分析首都医科大学附属北京妇产医院2014年1月至2014年3月住院分娩的单胎、妊娠满37~41周、无并发症及慢性疾病初产妇的临床资料共1 085例。根据世界卫生组织的体重标准,所有病例按产妇孕前体重指数(BMI)分为低体重组BMI18.5kg/m2、标准体重组BMI 18.5~24.9kg/m2、超重组BMI 25~29.9kg/m2、肥胖组BMI≥30kg/m2四个组;孕期体重增加分为低于IOM标准,符合IOM标准,超出IOM标准三组。采用χ2检验法比较各组、各变量间差异的统计学意义。结果孕前低体重指数孕妇占17.42%,孕前标准体重指数孕妇占72.72%。超重及肥胖孕妇占9.9%,其中1.4%达到肥胖标准。超重及肥胖组巨大儿的发生率随孕期体重增加而升高(P0.01)。孕期体重增加符合IOM标准时,仍有高度统计学意义(P0.01)。随孕前BMI的增加,巨大儿的发生率大幅度的增加(P0.01)。结论随着孕前BMI及孕期体重增加的增加巨大儿的发生率增加。提示加强对高危人群的孕前和孕期体重管理有助于预防巨大儿的发生、改善母婴预后。
[Abstract]:Objective to investigate the relationship between body mass index (BMI) before pregnancy and weight gain during pregnancy and the incidence of macrosomia. Methods the clinical data of 1085 parturients without complications and chronic diseases in Beijing Obstetrics and Gynecology Hospital affiliated to Capital Medical University from January 2014 to March 2014 were analyzed retrospectively. the pregnancy reached 37 weeks per 41 weeks. According to the body weight standard of the World Health Organization, all cases were divided into low weight recombinant BMI18.5kg/m2, standard recombinant BMI18.5 ~ 24.9 kg 鈮，
