摘要(Abstract):

目的探讨12 722例新生儿出生体质量及其影响因素。方法收集产科出生的12 722例活产新生儿及孕母围生期临床资料,统计新生儿(新生儿出生体质量等基本数据,早产儿、低出生体质量儿、巨大儿、过期产儿发生率)、产妇(产妇总数、初产妇人数、年龄、孕前BMI、孕期增重程度等)情况,对新生儿出生体质量的进行单因素分析,采用Logistics回归分析新生儿出生体质量的影响因素。结果 12 722例新生儿平均出生体质量为(3 324.37±457.64) g,男性高于女性(F=897.856,P<0.001);2012—2014年新生儿出生体质量逐年增加(F=36.552,P<0.001),2015—2019年逐年下降(F=10.663,P<0.001);2012—2019年早产儿的发生率总体保持递减趋势(χ2=37.751,P<0.001);2012—2019年产妇平均年龄逐年增大(χ2=57.865,P<0.001),30岁以上的产妇逐渐增多(χ2=37.751,P<0.001);2012—2019年产妇平均年龄逐年增大(χ2=57.865,P<0.001),30岁以上的产妇逐渐增多(χ2=49.537,P<0.001);2012年后孕前消瘦孕妇逐渐增多(χ2=19.228,P<0.001),孕前正常体质量产妇比例无明显改变(χ2=49.537,P<0.001);2012年后孕前消瘦孕妇逐渐增多(χ2=19.228,P<0.001),孕前正常体质量产妇比例无明显改变(χ2=0.806,P=0.652),孕前超重产妇比例下降(χ2=0.806,P=0.652),孕前超重产妇比例下降(χ2=14.559,P=0.001);单因素分析结果显示,不同性别、胎龄、出生胎儿数量新生儿的出生体质量比较,差异有统计学意义(P<0.001);不同年龄、文化水平、孕前BMI、孕期增重程度、羊水量、孕次、产次、身高以及有无患妊娠期高血压的产妇所产新生儿的出生体质量比较,差异有统计学意义(P<0.05);多Logistics回归分析果显示,新生儿出生体质量影响因素依次是双胎妊娠、胎龄、羊水量、妊娠期高血压、孕期增重程度、新生儿出生性别、产妇文化水平、妊娠糖期尿病、产妇年龄、孕前BMI、孕母身高、孕次以及产次。结论产妇年龄、孕前BMI、孕期增重程度、是否患妊娠期糖尿病和妊娠期高血压以及新生儿胎龄是新生儿出生体质量的影响因素。
Objective To investigate the birth weights of 12 722 newborns and its influencing factors.Methods The birth weights of 12 722 newborns and perinatal clinical data of pregnant women were collected in the department of obstetrics,including the newborn information(birth weight of newborns,incidence of premature newborns,low-birth weight newborns,mega newborns,and newborns after due date),maternal information(total number of mothers,number of primiparas,age,pre-pregnancy BMI,body weight gain during pregnancy,etc.).Univariate analysis was run on newborn birth weights.Logistic regression was used to analyze the influencing factors of newborn birth weights.Results The average birth weight of 12 722 newborns was(3 324.37±457.64) g.The average birth weight of male newborns was greater than that of female newborns(F=897.856,P <0.001).The birth average weight of newborns gradually increased from 2012 to 2014(F=36.552,P <0.001),but gradually decreased from 2015 to 2019(F=10.663,P <0.001).The incidence of preterm infants from 2012 to 2019 was decreased(χ2=14.559,P=0.001);单因素分析结果显示,不同性别、胎龄、出生胎儿数量新生儿的出生体质量比较,差异有统计学意义(P<0.001);不同年龄、文化水平、孕前BMI、孕期增重程度、羊水量、孕次、产次、身高以及有无患妊娠期高血压的产妇所产新生儿的出生体质量比较,差异有统计学意义(P<0.05);多Logistics回归分析果显示,新生儿出生体质量影响因素依次是双胎妊娠、胎龄、羊水量、妊娠期高血压、孕期增重程度、新生儿出生性别、产妇文化水平、妊娠糖期尿病、产妇年龄、孕前BMI、孕母身高、孕次以及产次。结论产妇年龄、孕前BMI、孕期增重程度、是否患妊娠期糖尿病和妊娠期高血压以及新生儿胎龄是新生儿出生体质量的影响因素。
