体重指数对围产保健意义的探讨

To Investigate the significance of body mass index in perinatal health care

目的 用孕妇不同体重指数对高危妊娠、妊娠结局及新生儿体重的影响进行初步探讨。方法 以 610例孕妇孕20周时的体重指数(BMI),将孕妇分为消瘦型、正常型、超重型三种类型人群组。结果 不同体重 指数孕妇孕中期体重增加幅度均大于孕晚期,差异有显著性意义;超重型孕妇新生儿体重明显高于其他两组(P< 0.01);超重型孕妇高危妊娠的发生率最高,其中巨大儿、妊高征的发生率高于消瘦型及正常型孕妇(P<0.01);消瘦 型孕妇IUGR、过期妊娠的发生率最高。不同体重指数孕产妇的分娩方式总体差异无显著性,但超重型孕产妇的 剖宫产率明显高于正常型孕产妇(P<0.01)。结论 不同体重指数孕妇与新生儿体重有相关影响,且高危妊娠的发 生率不同,但与分娩方式总体无明显差异。利用BMI个体化指导孕妇营养,对围产保健有一定意义。

object Initially investigate the effect of pregnant women's different Body mass Index on high risk pregnancy. Pregnancy outcome and fetal weight. Methods 610 pregnant women were divided into there groups according to maternal Body Weight Index (BWI) in gestational 20 weeks: under weight group, ideal weight group and over weight group. Results All the pregnant women's body weight was creased more significantly in second trimester than in late trimester; fetal weight was remarkable higher in over weight group than in other two groups. (P<0.01). In the over weight group, the rate of high risk pregnancy was the highest, and the incidence of fetal macrosomia and PIH was significantly higher than in under weight group and ideal weight group. (P < 0.01) while the incidence of 1UGR and posterm pregnancy was the highest in under weight group. Delivery mode of pregnancy women with different BMI was no significant difference among three groups. But the incidence of cesarean delivery was higher in over weight group than in ideal weight group( P < 0.01). Conclusions Maternal Body mass Index (BMI) has related effect on fetal weight. The rates of mode was total no significant different. To make use of MBI individuation intrusting pregnant women to control nutrition is definte significance in perinatal Health care.
