孕期体重增加与妊娠结局的相关性研究

Study on the Relationship Between Gestational Weight Gain and Pregnancy Outcome

目的探讨孕前体重指数及孕期体重增加与妊娠结局的相关性。方法选择458例孕前体重指数（BMI）为18.5-24的产妇,孕期体重增加〈15 kg的200例产妇为对照组,孕期体重增加〉15 kg的258例产妇为研究组,记录分析产妇的妊娠结局。结果研究组子痫前期、妊娠期糖尿病、剖宫产的发生率与对照组比较,差异有统计学意义（P〈0.05）,研究组巨大儿、低出生体重儿的比率与对照组比较,差异有统计学意义（P〈0.05）。结论重视孕期体重管理,控制孕期体重可以减少妊娠期并发症以及降低剖宫产的发生率。

Objective To discuss the correlation between pre-pregnancy body mass index and weight gain during pregnancy and pregnancy outcomes. Methods 458 cases of puerperas whose pre-pregnancy body mass index（BMI） was 18.5-24 were selected, 200 cases of pregnancy weight gain less than 15 kg as the control group, 258 cases of pregnancy weight gain more than 15 kg as the study group, their pregnancy outcomes were recorded. Results The incidence of pre-eclampsia, gestational diabetes and the rate of cesarean section of study group had differences compared with control group, which were statistically significant（P〈0.05）, the proportion of macrosomia, low birth weight infants of study group compared with control group, the differences were statistically significant（P〈0.05）. Conclusion The emphasis on pregnancy weight management amd weight control during pregnancy cam reduce pregnancy complications, and reduce the incidence of cesarean section.
