孕前体质量超重和偏瘦孕产妇的孕产情况比较

Comparison of preconception and maternal preconception between overweight and lean women

目的:探讨孕产妇孕前体质指数(BMI)对新生儿体质量的影响。方法:选择2019年在某县医疗保健机构建立孕产妇保健手册且有分娩结局且孕前BMI异常孕产妇359例,根据BMI分为体质量超重组(168例)和体质量偏瘦组(191例),分析两组孕妇孕期体质量增长、年龄、孕次、产次、妊娠合并症和新生儿出生体质量情况。结果:体质量超重组产次、分娩方式、新生儿出生体质量、年龄等与体质量偏瘦组对比,差异具有统计学意义(P<0.05)。结论:孕产妇体质量偏重、产次≥3次、剖宫产、年龄≥35岁等为导致新生儿体质量增加的关键原因,将孕妇BMI控制在合理范围内,可有效改善孕妇及其子代健康状态。

Objective:To explore the effects of pre-pregnancy body mass index(BMI)on neonatal weight.Method:359 pregnant women who registered maternal health handbooks in Lujiang county's healthcare institutions and had successful deliveries in 2019 were divided into 2 groups-overweight group(n=168)and underweight group(n=191)-based on their pre-pregnancy BMI.The effects of pregnancy weight gain,age of pregnant women,times of pregnancy and delivery,and pregnancy complications on neonatal weight were monitored.Result:There were significant differences in the age,times and mode of delivery,neonatal weight,etc.between overweight and underweight pregnant women(χ2 test showed P<0.05).Conclusion:Being overweight,aged 35 and above,having delivered more than twice or had cesarean section are key reasons for pregnant women to give birth to overweight neonates.Keeping BMI within a reasonable range can effectively improve the health conditions of pregnant women and their neonates.
