超重孕妇孕期体重增长与妊娠结局关系的探讨

摘要

Objective Objective:to investigate the effect of weight gain during pregnancy on pregnancy outcome in overweight pregnant women.Methods 500cases of singleton pregnancy body mass index with the method of random sampling from April 2014to April 2016in our hospital for production inspection and delivery system (BMI)clinical da-ta of overweight women were retrospectively analyzed.According to the 2009 American Institute of Medicine (IOM) pre-pregnancy weight and maternal weight gain for pregnant women as revised standard.According to the pre BMI packet divided into low body weight(BMI＜18.5)and normal BMI group (BMI =18.5-24.9), overweight(BMI=25-29.9)and obesity group(more than 30).Total weight gain during pregnancy overweight range(7-11.5Kg).According to the growth rate of overweight during pregnancy is divided into weight, lack of growth and weight normal growth and excessive weight gain group, and record the gestational hypertension, gestational diabetes, macrosomia, cesarean section, low birth weight and number of postpartum hemorrhage, the rate was calculated.Results Increase of body weight was 11.5kg in pregnant women with gestational hypertension, gestational diabetes, macrosomia, cesarean section, postpar-tum hemorrhage rate is higher than the weight growth of less than group and normal weight gain group (P＜0.05). The incidence of the three groups of delivery of low birth weight, no significant difference(P＞0.05).Conclusion O-verweight pregnant women excessive weight gain during pregnancy to increase pregnancy related complications, strengthen pre-pregnancy and pregnancy education, weight control and nutritional intervention, will effectively reduce the incidence of adverse pregnancy outcomes.%目的 探讨超重孕妇孕期体重增长与妊娠结局的关系.方法 用随机抽样的方法对2014年4月至2016年4月我院系统产检并分娩的500例单胎孕前体重指数(BMI)超重产妇的 临床资料进行回顾性分析.根据2009年美国医学研究院(IOM)修订的孕前体重及孕期增重指南作为孕妇分组的标准.根据孕前BMI的不同分为低体重组(BMI＜18.5)、正常BMI组(18.5≤ BMI≤24.9)、超重组(25≤BMI≤29.9)和肥胖组(≥30).超重组孕期总增重范围(7-11.5Kg).超重组按照孕期增长幅度再分为体重增长不足、体重增长正常和体重增长过多组,并 记录妊娠期高血压、妊娠期糖尿病、剖宫产、巨大儿、低出生体重儿及产后出血的人数,并计算其发生率.结果 体重增长≥11.5kg的孕妇妊娠期高血压、妊娠期糖尿病、剖宫产、巨大儿、 产后出血的发生率高于体重增长不足组及体重增长正常组(P＜0.05).三组对分娩低出生体重儿的发生率比较,差异无统计学意义(P＞0.05).结论 超重孕妇妊娠期体重增长过多将增 加妊娠相关并发症的发生,加强孕前及孕期宣教、控制孕期体重及营养干预,将会有效降低不良妊娠结局的发生.
