目的探讨孕前体重指数(BMI)和孕期增重对妊娠结局产生的影响,获得最适宜增重范围,为孕期体重管理提供依据。方法选取2014年3月-2015年9月在清远地区医院(连州镇中心医院、清远市保健院、清远市中医院、清远市清城区医院、清远第二人民医院)系统定期产检及分娩的首次怀孕的初产妇10 563例为研究对象,根据孕前BMI值不同将其分为体重过低组、正常体重组和超重组与肥胖组,统计其孕期增重,并对妊娠并发症及妊娠结局作分析及描述性研究。结果超重组与肥胖组孕妇的妊娠并发症发生率高于体重过低组及正常体重组,差异有统计学意义(P<0.05)。清远地区孕期适宜增重12~17.8 kg。孕期内适当增重者并发症发生率较低。结论孕前BMI及孕期增重对围产期并发症及新生儿有重要影响,孕妇孕前适宜体重及孕期体重增长在适宜水平能降低孕妇及新生儿并发症的发生率,有积极的临床意义。

Objective To discuss the effects of pre-pregnancy body mass index( BMI) and gestational weight gain on pregnancy outcome,in order to find the most appropriate weight gain range and provides basis for pregnancy weight management. Methods From March 2014 to September 2015,10 563 primiparae who went to the hospitals Qingyuan district for regular prenatal testing and delivery were selected as research objects,and they were divided into low weight group,normal weight group,overweight group and obesity group according to their pre-pregnancy BMI. Weight gain during pregnancy and the pregnancy complications as well as pregnancy outcome were analyzed. Results Pregnancy complications in overweight group and obesity group were higher than that in low weight group,normal weight group,and the differences were statistically significant( P < 0. 05). Appropriate weight gain during pregnancy were 12- 17.8 kg in Qingyuan area,gestational weight gain had lower complication occur. Conclusion Pregnancy BMI and weight gain during pregnancy have important effects on perinatal and neonatal complications; pregnant women control weight gain in the appropriate level can reduce the incidence rate of pregnant and newborn complications,which has positive clinical significance.
