A case-control study was performed to investigate the association between the categories avoidable and non-avoidable death and socio-demographic, maternal reproductive, and neonatal status. The study used multivariate logistic regression according to a hierarchical model to analyze 1,139 infant deaths from 2000 to 2003. The variables sex, maternal age, number of live born infants, type of pregnancy, place of birth, and 5-minute Apgar were not associated with avoidable deaths. However, maternal schooling <or= 3 years (RC = 1.56; 95%CI: 1.01-2.45); single mother (RC = 0.65; 95%CI: 0.49-0.86) or mother with a history of stillbirth (RC = 1.59; 95%CI: 1.01-2.48); congenital malformation (RC = 0.26; 95%CI: 0.18-0.37); cesarean section (RC = 1.52; 95%CI: 1.10-2.11), premature labor between 22 and 36 weeks (RC = 0.47; 95%CI: 0.34-0.65), birth weight < 2,500 g (RC = 0.51; 95%CI: 0.32-0.79); and neonatal age < 6 days (RC = 0.62; 95%CI: 0.42-0.89) were significantly associated with avoidable death. These findings can help identify infants at increased risk.
开展了一项病例对照研究，以调查可避免死亡与不可避免死亡类别与社会人口统计学、孕产妇生殖及新生儿状况之间的关联。该研究根据分层模型使用多变量逻辑回归分析了2000年至2003年的1139例婴儿死亡情况。变量性别、产妇年龄、活产婴儿数量、妊娠类型、出生地点和5分钟阿氏评分与可避免死亡无关。然而，母亲受教育年限≤3年（相对危险度=1.56；95%置信区间：1.01 - 2.45）；单身母亲（相对危险度=0.65；95%置信区间：0.49 - 0.86）或有死产史的母亲（相对危险度=1.59；95%置信区间：1.01 - 2.48）；先天性畸形（相对危险度=0.26；95%置信区间：0.18 - 0.37）；剖宫产（相对危险度=1.52；95%置信区间：1.10 - 2.11），22至36周早产（相对危险度=0.47；95%置信区间：0.34 - 0.65），出生体重<2500克（相对危险度=0.51；95%置信区间：0.32 - 0.79）；以及新生儿年龄<6天（相对危险度=0.62；95%置信区间：0.42 - 0.89）与可避免死亡显著相关。这些发现有助于识别风险增加的婴儿。
