沈阳地区孕期体重增长与妊娠结局关系研究

Study on the relationship between body weight gain during pregnancy and pregnancy outcome in Shenyang

目的:调查沈阳地区孕妇体重增长情况,探讨孕期体重增长与妊娠结局的关系。方法:单纯随机抽样方法抽取沈阳市10个区、县(市)2010年9～10月在妇幼保健机构建立《孕妇保健手册》的孕妇3 203例,自制调查问卷对孕妇整个孕期分4～7次不等进行体重等指标测量,同时追踪其妊娠结局,采用单因素分析方法进行统计分析。结果:孕前身体质量指数(BMI)越大,其新生儿体重越大;孕期体重增长与新生儿体重呈正的直线相关。结论:孕前低BMI孕妇若在孕期体重赶上增长,就能分娩出正常体重的新生儿;而孕前高BMI孕妇则必须减少孕期体重增长,才能分娩出正常体重的新生儿。
