摘　　要：运用1:1配对的病例对照研究方法分析1987～1992年中低出生体重新生儿(LBW)的流行因素。本次调查低出生体重百分比在不同年份波动较大,最高年份为5.38%,平均水平为2.76%。用配对卡方检验进行初步分析发现,母亲文化程度及母亲妊娠疾病、孕周、产次、双胎在0.05水平有显著性意义。配对多因素 Logistic 回归分析结果提示:(1)母亲文化程度为初等教育时,其 LBW 危险性较大。(2)母亲孕期患有妊娠疾病,与 LBW 的关系有统计学意义。(3)早产是对 LBW 危害相当大的因素。(4)双胎对于 LBW 的发生有重要意义,应加以重视。A1:1 matched case-control study was conducted in 41 cases with low birth weight(LBW)and 41 controls with normal birth weight from Guiyang Fourth People's Hospital.The total newborns with low birth weight account for about three percent of all live births in 1987-1992.This artical analyzed risk factor involving LBW by using paired chisquare test and multivariate logistic regression analysis.The results are as follows:(1)It is the risk factor involving LBW that the mothers of LBW in- fant have primary edueation(OR=2.22).(2)Preterm delivery(duration of pregnancy<37 weeks)is also risk factor to LBW(OR=29.67).(3)Complications during pregnancy such as toxemia were main fisk factor with statistical significance(OR=20.91).(4)Other factors are also important causes of LBW,for instance dual pregnancy etc.
