摘要
目的 探讨孕前体重指数及孕期体重增长对妊娠结局的影响。 方法 将 1998年 6月至1999年 6月间在我院行产前检查并住院分娩的 32 2 5例足月单胎初产妇按孕前体重指数分为低于标准体重、标准体重和高于标准体重三组 ,并随访其妊娠结局。 结果 (1)高于标准体重组孕产妇的妊娠并发症发生率 (32 .1% ) ,明显高于标准体重组 (18.0 % )和低于标准体重组 (2 0 .0 % ) ,具有统计学意义(P值均 <0 .0 5 ) ,而低于标准体重组和标准体重组孕产妇间的妊娠并发症发生率则差异无显著性 (P>0 .0 5 )。(2 )新生儿体重与三组孕妇的孕期体重增长具有直线相关关系 (相关系数 r分别为 0 .5 96 ,0 .32 8和 0 .2 49,P值均 <0 .0 1)。(3)低于标准体重组和标准体重组孕妇孕期体重增长≥ 18kg时 ,妊娠高血压综合征的发病率明显增加 (10 .5 % ) ;而高于标准体重组孕妇孕期体重增长≥ 9kg时 ,其妊娠高血压综合征发病率就显著增加 (2 0 .2 % )。 结论 (1)孕前体重指数及孕期体重增长是妊娠并发症发生的重要影响因素。(2 )孕妇的体重增长对新生儿的体重有重要的影响作用 ;3.孕前体重指数不超过2 4,孕期体重增长适宜者 ,可获得良好的妊娠过程和结局。
Objective To investigate the effect of pre pregnancy body mass index and maternal weight gain on pregnancy outcome. Methods The data of 3225 cases of single term birth primigravidae were collected from Guangzhou Maternity and Infant Hospital from June 1998 to June 1999. All of the cases were divided into three groups according to pre pregnancy body mass index (BMI): under weight group (BMI<18),ideal weight group (18≤BMI<24) and over weight group (BMI≥24). The pregnancy outcome of 3225 cases were followed. Results 1.The incidence of maternal complications was significantly higher in the over weight group (32.1%) than in the ideal weight group (18.0%) and the under weight group (20.0%), however, there was no difference between the ideal weight group and the under weight group ( P >0.05). 2 Neonatal birth weight had a positive lineal correlation with the maternal weight gain in the three groups (calculated coefficient r were 0.596, 0.328 and 0.249, both of the P value were less than 0.01). 3 The incidence of pregnancy induced hypertension (PIH) increased significantly when maternal weight gained≥18 kg in the under weight and the ideal weight groups ( P <0.05), in the over weight group, the incidence of PIH increased significantly when maternal weight gained≥9 kg ( P <0.05). Conclusions 1 Pre pregnancy body mass index and maternal weight gain are critical factors on maternal complications. 2 Maternal weight gain during pregnancy plays an important role in neonatal birth weight.3 The authors assume that better pregnancy outcome could be obtained if the pre pregnancy body weight index is less than 24 and a maternal weight gain is appropriate during pregnancy.
