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。
Objective: To investigate the situation of weight gain in pregnant women in Shenyang and to explore the relationship between pregnancy weight gain and pregnancy outcome. Methods: A total of 3 203 pregnant women with 10 maternal and child health care manuals were set up in 10 districts and counties (cities) from September to October in 2010 in a randomized sampling method. Self-made questionnaires were applied to pregnant women for 4 to 7 Times ranging from weight measurement and other indicators, while tracking their pregnancy outcome, using univariate analysis of statistical methods. Results: The greater body mass index (BMI) before pregnancy, the greater the weight of its newborn; weight gain during pregnancy and newborn weight was a positive linear correlation. Conclusion: Pregnant women with low BMI can get normal weight of newborns if they gain weight during pregnancy. However, pregnant women with high BMI must reduce their weight gain during pregnancy before they can give birth to newborns of normal weight.
