摘　　要：目的探究孕期体重管理对分娩结局的影响。方法 300例无妊娠合并症的单胎妊娠初产妇,在知情同意的基础上随机将其分为对照组与观察组,每组150例。对照组给予常规产前教育与孕期指导;观察组在常规产前教育与孕期指导的基础上给予营养指导合理控制体重。记录两组不同孕周的孕期体质量指数(BMI)、分娩方式、自然分娩会阴损伤与产后出血情况,以及新生儿体重情况。结果两组建卡时BMI比较差异无统计学意义(P>0.05);观察组怀孕24周、35周及分娩时BMI均低于对照组,差异均具有统计学意义(P<0.05)。观察组自然分娩率为82.67%,高于对照组的57.33%,差异具有统计学意义(P<0.05)。观察组自然分娩患者中会阴损伤及产后出血发生率25.81%、1.61%均低于对照组的53.49%、6.98%,差异均具有统计学意义(P<0.05)。观察组正常儿所占比例(98.67%)高于对照组(84.00%),差异具有统计学意义(P<0.05)。结论初产妇实施孕期体重管理可有效改善分娩结局,降低巨大儿出生率,减少自然分娩会阴损伤率与产后出血率。Objective To explore the influence of pregnancy weight management on delivery outcome.Methods A total of300singletons primipara without complication of pregnancy were randomly divided on the basis of informed consent into control group and observation group,with150cases in each group.The control group received conventional prenatal education and guidance during pregnancy,and the observation group received nutrition guidance to control weight on the basis of conventional prenatal education and guidance during pregnancy.Record were made on body mass index(BMI)during pregnancy in different gestational ages,delivery modes,natural childbirth perineal injury,postpartum hemorrhage situation and neonatal weight situation in two groups.Results Both groups had no statistically significant difference in BMI at card open(P>0.05).The observation group had lower BMI at24,35weeks of pregnancy,and delivery than the control group,and the difference had statistical significance(P<0.05).The observation group had higher natural delivery rate as82.67%than57.33%in the control group,and the difference had statistical significance(P<0.05).The observation group had lower perineal injury and postpartum hemorrhage rate in natural delivery patients as25.81%and1.61%than53.49%and6.98%in the control group,and their difference had statistical significance(P<0.05).The observation group had higher normal infants proportion as98.67%than84.00%in the control group,and the difference had statistical significance(P<0.05).Conclusion Pregnancy weight management in primipara can effectively improve delivery outcome,decrease macrosomia birthrate and reduce natural childbirth perineal injury and postpartum hemorrhage rate.
