目的探讨孕妇孕前体重指数(BMI)、孕期总增重、孕中晚期增重速度的现状及对新生儿出生体重的影响。方法收集了部分于2014年9月至2015年7月于首都医科大学宣武医院正常产检并分娩的孕妇进行前瞻性纵向研究。结果 1孕中晚期增重速度及孕期总增重超出IOM标准组大于胎龄儿发生率高于低于IOM标准组。2孕中期增重速度与新生儿出生体重(r=0.439,P<0.001)呈正相关。孕晚期增重速度与新生儿出生体重(r=0.224,P<0.001)呈正相关。结论孕中晚期增重速度与新生儿出生体重呈正相关。建议首都医科大学宣武医院加强孕妇孕期营养知识的宣教及孕期体重的监测及干预。
Objective To investigate the status of pregnant women with body mass index (BMI) before pregnancy, total weight gain during pregnancy, rate of weight gain in the second trimester of pregnancy and the impact on newborn birth weight. Methods A prospective longitudinal study was conducted in part of pregnant women who received regular deliveries and deliveries at Xuanwu Hospital, Capital Medical University from September 2014 to July 2015. Results 1 The rate of weight gain in the second trimester and the total weight gain during pregnancy were higher than those in the IOM standard group and those with greater than gestational age were higher than those in the IOM standard group. The second trimester weight gain rate was positively correlated with newborn birth weight (r = 0.439, P <0.001). The rate of weight gain in the third trimester was positively correlated with the birth weight (r = 0.224, P <0.001). Conclusion The rate of weight gain in the second trimester is positively correlated with the birth weight of neonates. Proposed Xuanwu Hospital, Capital Medical University to strengthen the knowledge of pregnant women during pregnancy nutrition awareness and pregnancy weight monitoring and intervention.
