孕前体质量指数及孕期体质量指数增幅与妊娠结局相关性分析

Correlation analysis of pregnancy BMI and BMI increased during pregnancy and pregnancy outcome

目的观察孕前体质量指数(BMI)及孕期BMI增幅与妊娠结局相关性。方法选择我院进行产前检查、围产期保健和分娩的孕妇380例作为研究对象,比较不同孕前BMI及孕期BMI增幅孕产妇之间妊娠结局差异。结果孕前消瘦10.53%、正常体重76.32%、超重肥胖13.16%,三组不同孕前BMI孕产妇妊娠结局比较具有显著性差异(P<0.05),超重肥胖组存在妊娠并发症18.00%、产程异常22.00%、剖宫产76.00%、巨大儿14.00%、Apgar评分<8分36.00%高于正常体重组的5.51%、5.86%、35.17%、3.44%、8.28%(P<0.05),消瘦组与正常体重组无显著性差异(P<0.05)。BMI增幅偏低组13.16%、BMI增幅均衡组71.05%、BMI增幅偏高组15.79%;三组不同孕期BMI增幅孕产妇妊娠结局比较有显著性差异(P<0.05),BMI增幅偏高存在妊娠并发症23.33%、产程异常25.00%、剖宫产70.00%、巨大儿15.00%、Apgar评分<8分30.00%高于BMI增幅均衡的3.70%、4.44%、31.48%、2.59%、8.89%(P<0.05);BMI增幅偏低组与BMI增幅均衡组无显著性差异(P<0.05)。结论孕前BMI和孕期BMI增长和妊娠结局的关系密切,应指导孕妇孕期BMI保持在最佳范围内,以获得满意妊娠结局。

Objective To observe pre pregnancy BMI and maternal BMI increase and pregnancy outcome correlation.Methods 380 pregnant women who carried out prenatal examination, perinatal health care and childbirth were selected as the research subjects.The difference of pregnancy outcomes between pregnant and lying in pregnant women was compared with the different prepregnancy BMI and the BMI during pregnancy.Results Pre pregnancy weight loss 10.53%,normal weight 76.32%, overweight and obesity 13.16%.There was a significant difference in pregnancy outcome between three groups of pregnant women with different prepregnancy BMI（P〈0.05）.The overweight and obesity group had pregnancy complications18.00%,birth process abnormality 22.00%,cesarean section 76.00%,macrosomia14.00%,Apgar score8 36.00%higher than that of the normal weight group5.51%,5.86%,35.17%,3.44%,8.28%（P〈0.05）,There was no significant difference between the weight group and the normal weight group（P〈0.05）.The growth of BMI 13.16%,BMIgrowth equilibrium group 71.05%,BMI increase 15.79%;There was a significant difference in pregnancy outcomes between the three groups of pregnant and lying in pregnant women（P〈0.05）.The high volume of BMI pregnancy complications 23.33%,The abnormality of labor 25.00%,cesarean section 70.00%,macrosomia 15.00%,Apgar score8,30.00% higher than BMI increasing 3.70%,4.44%,31.48%,2.59%,8.89%（P〈0.05）.There was no significant difference between the group of low BMI and the balance group of BMI（P〈0.05）.Conclusion The relationship between pre pregnancy BMI and pregnancy BMI growth and pregnancy outcome is closely related.It should guide pregnant women to maintain the optimal range of pregnancy BMI in order to obtain satisfactory pregnancy outcome.
