摘　　要：目的:探讨产妇孕前体质指数(BMI)及孕期体重增长对新生儿体重的影响。方法:1 160例足月、单胎健康产妇,根据IOM指南对孕前BMI及体重增长情况进行分组,分析孕前BMI、体重增长情况及与新生儿体重的关系。结果:1 160名产妇中,孕前体重正常820例,消瘦265例,超重及肥胖75例,32.8%孕妇孕期体重增长过多,孕前消瘦及孕期体重增长不足产妇产下的低体重儿比例较高(14例及12例),孕前超重及肥胖、孕期体重增长过多产妇产下的巨大儿较多(11例及38例)。结论:孕前及孕期体重增长情况对新生儿体重有影响,控制孕前BMI和孕期体重增长很有必要。Objective：To analyze the effect of BMI before pregnancy and weight gain during pregnancy of puerperant women on neonatal weight.Methods：BMI before pregnancy,weight gain during pregnancy of 1 160 puerperant women and neonatal weight in three first class hospitals was collected.The effect of BMI before pregnancy and weight gain during pregnancy on neonatal weight was analyzed.Results：In 1 160 puerperant women,the ratio of overweight and obesity before pregnancy was 6.5%,and 32.8% of them got excessive weight gain.Those whoes BMI before pregnancy was normal got more reasonable weight gain（41.1%）,while the overweight and obesity ones got more excessive weight gain （54.7%）,there was statistical difference （x2 =21.097,P 〈0.01）.Puerperant women who were emaciation before pregnancy or whose body weight growth deficiency held higher probability for delivering babies with low birth weight （5.3% and 3.8% respectively）,on the contrary,overweight,obesity and excessive weight gain puerperant women held higher probability for delivering giant babies （14.7% and 10.0% respectively）,there was statistical difference （P 〈 0.01）.Conclusions：Weight gain during pregnancy is associated with BMI before pregnancy,controlling BMI before pregnancy and weight gain during pregnancy can decrease the rate of abnormal neonatal weight effectively.
