【摘要】：目的观察并分析单胎孕妇孕前BMI及产次对孕期增重的影响。方法收集2013年9月~2014年4月在郑州大学第三附属医院分娩的1 252例孕妇的临床资料。采用χ2检验比较不同年龄、文化程度、孕前BMI、产次、孕周及分娩方式的孕妇孕期增重情况,采用无序多分类Logistic回归分析法分析孕前BMI、产次与孕期增重的关系。结果 1 252名孕妇中,孕前消瘦者孕期增重适宜的比例高于孕前超重及肥胖者(P0.01),孕期增重过多的比例低于孕前超重及肥胖者(P0.01);孕前BMI正常者孕期增重过多的比例也低于孕前超重及肥胖者(P0.01)。经产者孕期增重不足和增重适宜的比例均低于初产者(P0.01),孕期增重过多的比例高于初产者(P0.01)。调整年龄、文化程度后,与初产妇相比,经产妇孕前消瘦风险降低(OR=0.393,95%CI:0.260~0.594),但孕前超重及肥胖的风险升高(OR=2.050,95%CI:1.368~3.072)。将产次分层后,孕前超重及肥胖的初产妇发生孕期增重过多的风险高于孕前BMI正常者(OR=5.378,95%CI:2.424~11.913)。将孕前BMI分层后,孕前BMI正常的经产妇孕期增重过多的风险高于初产妇(OR=1.771,95%CI:1.287~2.437);孕前超重及肥胖的经产妇孕期增重不足的风险低于初产妇(OR=0.216,95%CI:0.065~0.718)。结论初产妇和经产妇孕期增重过多比例均较高;孕前BMI和产次是孕期增重的独立影响因素;相比孕前BMI正常者,孕前超重和肥胖的初产妇孕期增重过多的风险更大;经产会增加孕期增重过多的风险,同时降低孕期增重过少的风险。
[Abstract]:Objective to observe and analyze the effect of BMI and delivery time on weight gain during pregnancy. Methods Clinical data of 1 252 pregnant women delivered in the third affiliated Hospital of Zhengzhou University from September 2013 to April 2014 were collected. 蠂 2 test was used to compare the pregnancy weight gain of pregnant women with different age, education level, BMI, birth time, gestational week and delivery mode. The relationship between BMI, delivery time and pregnancy weight gain was analyzed by disordered multiple classification Logistic regression analysis. Results among 1,252 pregnant women, The appropriate proportion of weight gain during pregnancy in patients with weight loss before pregnancy was higher than that in those who were overweight and obese before pregnancy (P0.01), the proportion of excess weight gain during pregnancy was lower than that in those with overweight and obesity before pregnancy (P0.01), and the proportion of excess weight gain during pregnancy in patients with normal BMI before pregnancy was also lower than that in those with overweight and obesity before pregnancy (P0.01). The proportion of insufficient weight gain and appropriate weight gain during pregnancy was lower than that in the first delivery (P0.01), and the proportion of excess weight gain during pregnancy was higher than that in the first delivery (P0.01). After adjusting for age and education, the risk of pre-pregnancy wasting (OR=0.393,95%CI:0.260~0.594) was lower than that of primipara, but the risk of overweight and obesity (OR=2.050,95%CI:1.368~3.072) was increased before pregnancy. The risk of excess weight gain during pregnancy in prepregnancy overweight and obese primipara was higher than that in normal prepregnancy BMI (OR=5.378,95%CI:2.424~11.913). After stratification of BMI before pregnancy, the risk of excessive weight gain in pregnant women with normal BMI before pregnancy was higher than that in primipara (OR=1.771,95%CI:1.287~2.437), and the risk of insufficient weight gain during pregnancy in overweight and obese women before pregnancy was lower than that in primipara (OR=0.216,95%CI:0.065~0.718). Conclusion the proportion of excess weight gain during pregnancy is higher in primipara and menstrual women, BMI and delivery before pregnancy are independent influencing factors of weight gain during pregnancy, and the risk of excessive weight gain during pregnancy is higher in those with normal BMI before pregnancy than those with normal BMI before pregnancy, and the risk of excessive weight gain in pregnant women with overweight and obesity before pregnancy is higher than that with normal BMI before pregnancy. Childbirth increases the risk of excess weight gain during pregnancy and reduces the risk of too little weight gain during pregnancy.
