四川农村婴儿和儿童死亡的危险因素研究

A STUDY ON RISK FACTORS FOR INFANT AND CHILD MORTALITY IN SICHUAN

随机抽查四川五县50个乡镇中1985～1987年间1个月至6岁的死亡764例,其中1～12个月组435例,1～6岁组329例。两对照组分别有531例和1414例。用非条件 logistic 回归模型,分别分析两组死亡的16个危险因素。结果与婴儿期死亡有关的危险因素有早产、家中产、旧法接生、多胎、有流产引产史、母亲文化低、父母近亲结婚等。与1～6岁组儿童死亡有关的危险因素有早产、家中产、母亲文化低、父亲文化低、父母近亲结婚等。研究结果能够被两年龄段的前四位主要死因所解释。
