早产低体重儿相关影响因素分析

Analysis on Influencing Factors of Premature and Low Birth Weight Infants

目的探讨早产低出生体重儿发生的相关影响因素。方法分析398例早产低出生体重儿的一般情况、产科及母孕期情况。采用多元逐步回归分析对398例早产低出生体重儿母亲年龄、多胎妊娠、孕周、胎盘早剥、胎膜早破、妊娠高血压综合征、母亲贫血、羊水异常、母亲心血管疾病等与早产低出生体重的关系进行分析。结果孕周≤32周16.3%;胎盘早剥12.8%;胎膜早破48.2%;多胎妊娠35.9%;妊娠高血压综合征21.9%;母亲贫血27.9%;羊水异常11.1%;母亲心血管疾病2.5%。孕周、妊娠高血压综合征、胎盘早剥是早产低出生体重发生的重要影响因素。结论加强孕期保健,早期诊断及防治妊娠期合并症及并发症有利于预防和减少早产低出生体重儿的发生。

Objective To explore the influencing factors of premature and low birth weight infants.Methods Common complexion,tocology and gestation complexion of 398 premature and low birth weight neonates and mother were examined.The correlation between premature and low birth weight neonates with age of mother,twin gestation,gestation week,placenta peeling early,caul breakage early,pregnancy induced hypertension,anemia of mother,abnormity of amniocentesis,disease of heart and vas of mother were analyzed by multiple regression analysis.Results Gestation week ≤32 weeks was 16.3%,placenta peeling early was 12.8%,caul breakage early was 48.2%,twin gestation was 35.9%,pregnancy induced hypertension was 21.9%,anemia of mother was 27.9%,abnormity of amniotic water was 11.1%,disease of heart and vas of mother was 2.5%.Gestation week,pregnancy induced hypertension,and placenta peeling early were the important influencing factors of occurring premature and low birth weight infant.Conclusions Intensifying health care of gestation,diagnosing early,and preventing and curing syndrome of gestation would be benefit to prevent and reduce the incidence of premature and low birth weight infant.
