摘要
目的:探讨孕妇产前BMI及孕期BMI增幅对分娩方式、新生儿体重的影响。方法:选取单胎初孕妇360人作为研究对象,产前BMI≥28为肥胖组、产前BMI<28为正常组及孕期BMI增幅<4为Ⅰ组,4≤BMI≤6为Ⅱ组,>6为Ⅲ组。以分娩方式、新生儿出生体重为观察指标,对各组进行随访。结果:产前肥胖组剖宫产、新生儿体重明显增加(P<0.05);孕期BMI增幅≥4孕妇剖宫产增加、孕期BMI增幅>6孕妇巨大儿明显增加(P<0.05)。结论:产前BMI及孕期BMI增幅与妊娠结局有关,控制孕期体重过度增长,可降低母婴并发症。
Objective: To explore the effects of prenatal body mass index ( BMI) ,increase amplitude of gestational BMI on delivery modes and neonatal birth weight. Methods: 360 primiparous women of single birth were selected and divided into obesity group ( prenatal BMI≥28) and normal weight group ( prenatal BMI 28) ,at the same time,they were divided into group Ι ( increase amplitude of gestational BMI 4) ,group Ⅱ ( 4≤increase amplitude of gestational BMI≤6) and group Ⅲ ( increase amplitude of gestational BMI 6) . Among those groups,delivery modes and neonatal birth weight were observed and followed up. Results: The rate of cesarean section and neonatal weight increased significantly in obesity group ( P 0. 05) ; the rate of cesarean section in pregnant women with increase amplitude of gesta- tional BMI≥4 and the incidence of macrosomia in pregnant women with increase amplitude of gestational BMI 6 increased significantly ( P 0. 05) . Conclusion: Prenatal BMI and increase amplitude of gestational BMI are related to pregnancy outcomes,controlling pregnancy weight gain can reduce the complications of mothers and infants.
