目的:探讨孕期体重增长对分娩方式及围产儿结局的影响。方法:取2005年1月～2006年1月在我院进行产前检查并分娩的单胎初产妇450例,根据孕前体重指数(BMI)分为3组:正常组18.5≤BMI<23,超重组23≤BMI<25,肥胖组BMI≥25。再按照孕期体重增长幅度分为3组:A组BMI增幅<4,B组4≤BMI增幅<6,C组BMI增幅≥6。探讨各组巨大儿发生率、剖宫产率及出现产科并发症的情况。结果:孕前肥胖组及孕期体重过度增加组巨大儿发生率、剖宫产率明显高于正常组。结论:提高围产期保健质量,加强营养指导,避免肥胖,对减少母婴并发症至关重要。
Objective: To investigate the effects of pregnancy weight gain on delivery mode and perinatal outcome. Methods: From January 2005 to January 2006 in our hospital for prenatal care and delivery of singleton primiparous 450 cases, according to pre-pregnancy body mass index (BMI) is divided into 3 groups: normal group 18.5≤BMI <23, super Recombination 23 ≤ BMI <25, obese group BMI ≥ 25. According to the weight gain during pregnancy, the patients were divided into 3 groups: the increase of BMI in group A was less than 4, the increase of 4≤BMI in group B was less than 6, and the increase of BMI in group C was no more than 6. To investigate the incidence of huge children in each group, cesarean section rate and the occurrence of obstetric complications. Results: The incidence of macrosomia and cesarean section rate in pre-pregnancy obese group and overweight during pregnancy were significantly higher than those in normal group. Conclusion: Improving the quality of perinatal care, strengthening nutritional guidance and avoiding obesity are crucial for reducing maternal and infant complications.
