摘　　要：目的 调查分析双胎妊娠孕妇孕期增重情况与妊娠结局的关系。方法 对2009年10月-2014年9月在南方医科大学南方医院分娩的308例双胎妊娠孕妇的病历资料进行回顾性分析,按分娩孕周、孕前BMI及孕期增重分组。结果 308例双胎妊娠孕期增重为（16.21±5.36）kg,足月妊娠者孕期平均增重（17.39±5.30）kg。孕前超重及肥胖者孕期增重低于孕前低体重者（F=3.24,P〈0.05）。新生儿平均出生体重（2.33±0.52）kg,低出生体重儿发生率为52.0%。在校正孕周、孕前BMI等因素后,孕期增重每增加1kg,双胎出生体重之和增加0.04 kg。孕期增重≥21.0 kg者剖宫产率高达96.5%。孕期增重≤13.0 kg是分娩低出生体重儿的危险因素,孕期增重〈21.0 kg者妊娠期高血压疾病的发生风险显著降低。结论 双胎妊娠孕期增重影响妊娠结局,双胎妊娠孕妇孕期增重13-21 kg较适宜,可减少低体重儿和妊娠期高血压风险,应加强双胎妊娠孕妇的孕期营养指导。Objective：To survey and analyze the relationship between body weight gain during pregnancy and pregnancy outcome among the women with twin pregnancy.Methods：The data of 308 women with twin pregnancy who gave birth to their babies in the hospital from October 2009 to September 2014 were analyzed retrospectively,then the women were divided into different groups according to delivery pregnancy week,pre-pregnancy body mass index（BMI）,and body weight gain during pregnancy.Results：The average body weight gain during pregnancy of 308 women with twin pregnancy was（16.21 ± 5.36） kg,the average body weight gain during pregnancy of full-term pregnant women was（17.39±5.30） kg.The body weight gain during pregnancy among the overweight and obese women before pregnancy was statistically significantly lower than that among the women with low body weight before pregnancy（F = 3.24,P〈0.05）.The average neonatal birth weight was（2.33 ± 0.52） kg,the incidence rate of low birth weight infants was 52.0%.After adjusting gestational week and pre-pregnancy BMI,the sum of twins＇ birth weight increased by 0.04 kg when the body weight gain during pregnancy increased by 1 kg.Among the pregnant women with body weight gain during pregnancy more than or equal to 21.0 kg,the cesarean section rate was 96.5%.Body weight gain during pregnancy less than or equal to 13.0 kg was a risk factor of low birth weight infants,the risk of hypertensive disorder complicating pregnancy（HDCP） decreased significantly among the pregnant women with body weight gain during pregnancy less than21.0 kg.Conclusion：Body weight gain during pregnancy among the women with twin pregnancy affects pregnancy outcome.The appropriate increasing amplitude of body weight during pregnancy is 13-21 kg,which can reduce the risk of low birth weight infants and HDCP,nutritional guidance during pregnancy should be strengthened.
