摘　　要：目的:分析孕期增重对新生儿体质量和不良分娩结局的影响。方法:回顾性分析2022年10月至2023年10月于该院建档分娩的1429名产妇的临床资料,根据孕期增重不同将其分为增重过少组(n=64)、增重适度组(n=490)、增重过多组(n=875)。比较三组新生儿出生体质量和不良分娩结局,并采用Logistic回归分析孕期增重对新生儿体质量和不良分娩结局的影响。结果:三组低体质量儿、正常体质量儿的占比比较,差异均无统计学意义(P>0.05);增重适度组低体质量儿的占比低于增重过少组,正常体质量儿的占比高于增重过多组,巨大儿的占比低于增重过多组,增重过少组低体质量儿的占比高于增重过多组,差异均有统计学意义(P<0.05);增重适度组早产的占比低于增重过少组,胎儿窘迫、剖宫产、产程延长的占比均低于增重过多组,差异有统计学意义(P<0.05);增重过少组剖宫产、产程延长的占比均低于增重过多组,差异有统计学意义(P<0.05);Logistic回归分析结果显示,孕期增重对发生胎儿窘迫无影响(P>0.05);孕期增重过少是发生剖宫产、巨大儿、产程延长的保护因素(OR<1,P<0.05);孕期增重过少是发生早产的危险因素(OR>1,P<0.05);孕期增重过多是发生早产、剖宫产、巨大儿、产程延长的危险因素(OR>1,P<0.05)。结论:孕期增重过少是发生剖宫产、巨大儿、产程延长的保护因素,孕期增重过少是发生早产的危险因素,孕期增重过多是发生早产、剖宫产、巨大儿、产程延长的危险因素。Objective:To analyze effects of weight gain during pregnancy on neonatal weight and adverse delivery outcomes.Methods:The clinical data of 1429 pregnant women who delivered in this hospital from October 2022 to October 2023 were retrospectively analyzed.According to the weight gain during different pregnancy,they were divided into too little weight gain group(n=64),moderate weight gain group(n=490)and excessive weight group(n=875).The birth weights and the adverse delivery outcomes of the three groups were compared.Logistic regression was used to analyze the effects of weight gain during pregnancy on neonatal weight and adverse delivery outcomes.Results:There were no significant differences in the proportions of low birth weight infants and normal birth weight infants among the three groups(P>0.05).The proportion of low birth weight infants in the moderate weight gain group was lower than that in the too little weight gain group,the proportion of normal birth weight infants was higher than that in the excessive weight gain group,the proportion of macrosomia was lower than that in the excessive weight gain group,the proportion of low birth weight infants in the too little weight gain group was higher than that in the excessive weight gain group,and the differences were statistically significant(P<0.05).The proportion of preterm birth in the moderate weight gain group was lower than that in the too little weight gain group,the proportions of fetal distress,cesarean section and prolonged labor in the moderate weight gain group was lower than that in the excessive weight gain group,and the differences were statistically significant(P<0.05).The proportions of cesarean section and prolonged labor in the too little weight gain group was lower than that in the excessive weight group,and the differences were statistically significant(P<0.05).Logistic regression analysis showed that weight gain during pregnancy had no effect on fetal distress(P>0.05);too little weight gain during pregnancy was a protective factor for cesar
