农村妇女孕期体重对妊娠结局的影响

目的:探讨农村妇女孕期体重与妊娠结局的关系,为农村孕妇的体重管理提供理论依据。方法:收集2014年2月至2015年2月禹城市人民医院产一科住院分娩的单胎妊娠农村初产妇896例,按孕前体重指数(BMI)分为孕前消瘦组(≤18.5kg/m~2)、孕前体重正常组(18.5kg/m~2BMI24kg/m~2)、超重组(24kg/m2≤BMI28kg/m~2)、肥胖组(≥28kg/m~2);按孕期体重增长分为体重增长适宜组及体重增长过度组。分析各组孕妇妊娠结局及并发症的发生情况。结果:孕前超重组与孕前体重正常组比较,孕期体重增长过度组与孕期体重增长适宜组比较,均显著增加妊娠期高血压疾病、妊娠期糖尿病、剖宫产、产后出血、巨大儿的风险,差异有统计学意义(P0.05)。结论:孕前超重与孕期体重增长过度是导致农村孕妇不良妊娠结局的危险因素,应加强孕妇的体重管理,降低妊娠不良结局发生。

Relationship of pregnancy obesity and pregnancy outcomes among rural pregnant women

Objective:To explore the relationship of pregnancy obesity and pregnancy outcomes among rural pregnant women. Methods:A total of 896 full-term primiparas who deliv-ered a singleton infant from Feb. 2014 to Feb. 2015 in Yucheng City People's Hospital were en-rolled. The women were divided into four groups according to body mass index( BMI) ,were di-vided into two groups according to different ranges of body weight increase during pregnancy. Then to compare the relationship of obstetric complications and delivery outcomes between dif-ferent groups. Results:Pre-Pregnancy obesity and excessive weight gain group compared with appropriate weight gain group during pregnancy had significantly increased the risk of gestation-al hypertension,gestational diabetes,cesarean section,postpartum hemorrhage and macrosomia. The difference was statistically significant ( P<0 . 05 ) . Conclusions:Both pre-pregnancy obesity and excess gestational weight gain can significantly increase the risk of adverse pregnancy com-plications among rural pregnant women. We should strengthen the weight management during pregnancy of rural women in order to reduce the worse pregnancy outcome.
