孕妇肥胖对分娩方式及新生儿体重的影响

目的:探讨孕妇肥胖对分娩方式及新生儿体重的影响。方法:选取单胎初产妇360例作为研究对象,按照孕妇体重指数(BMI)分组。孕前肥胖组33例,孕前体重正常组327例;产前肥胖组204例,产前体重正常组156例;按孕期体重绝对增加值分组分为≤10kg(A组)、10.5～15kg(B组)、15.5～20kg(C组)、20.5～25kg(D组)、>25.5kg(E组)共5组。以分娩方式及新生儿体重为观察指标对各组进行分析比较。结果:孕前肥胖组分娩方式、新生儿体重与孕前正常组比较差异无统计学意义(P>0.05);产前肥胖组剖宫产、新生儿出生体重与产前正常组比较差异有统计学意义(P<0.05);C、D、E3组分别与A、B两组比较,巨大儿、剖宫产率差异有统计学意义(P<0.01)。结论:加强围产期保健,控制孕期体重,避免肥胖,可减少母婴并发症。

Effect of obese pregnant women on delivery modes and neonatal weight

Objective: To explore the effect of obese pregnant women on delivery modes and neonatal weight. Methods: 360 single birth, primiparous women were selected and divided into four groups according to body mass index (BMI) : pre-pregnancy obesity group (n = 33), pre-pregnancy normal weight group (n = 327), antenatal obesity group (n = 204) and antenatal normal weight group (n = 156)At the same time, the 360 primiparoas women were divided into five groups according to the numerical value of absolute gestational weight gain: ≤10kg group (group A), 10. 5 ～15kg group (group B), 15.5 ～20kg group (group C), 20.5 ～25kg group (group D), >25.5kg group (group E) . The delivery modes and neonatal weight between the groups were analyzed and compared. Results: There was no significant difference in the delivery modes and neonatal weight between pie-pregnancy obesity group and pie-pregnancy normal weight group (P > 0. 05) ; there was significant difference in cesarean rate and neonatal weight between antenatal obesity group and antenatal nor-mal weight group (P < 0. 05) ; there was significant difference in cesarean rate and the rate of macrosomia between group C, group D, group E and group A, group B (P <0.01) . Conclusion: Strengthening perinatal health care and controlling pregnancy weight gain can lower complications incidence of mothers and infants.
