为揭示近７年山东省城乡婴儿死亡主要危险因素及其变动情况，采用山东省长期疾病监测系统１９８４年及１９９４年婴儿死亡监测数据，对影响婴儿死亡的１３项因素作了非条件ｌｏｇｉｓｔｉｃ回归分析。结果表明，城市近１０年婴儿死亡的危险因素是出生体重、母亲分娩年龄、孕期长短及孕期健康状况，其综合人群归因危险度１９８４年为９２．２４％，１９９４年为９３．８１％；农村婴儿死亡除与城市具有共同的危险因素外，还受分娩方式、孕期不良生活事件的影响，５因素综合人群归因危险度１９９４年高达９８．０７％。农村由家庭接生员接生的婴儿死亡危险近１０年大幅度减少，１９８４年ＯＲ值为４．１４５０，至１９９４年该因素未被选入多变量模型。
In order to reveal the main risk factors and changes of infant deaths in urban and rural areas of Shandong Province in the recent 7 years, non-conditional logistic regression analysis of 13 factors influencing infant deaths was conducted using the data of infant mortality monitoring in 1984 and 1994 of Shandong Long-term Disease Surveillance System . The results showed that the risk factors of infant mortality in recent 10 years in city were birth weight, mother ’s delivery age, length of pregnancy and health during pregnancy. The risk of attributive population in general population was 92.24% in 1984 and 93.81% in 1994. In addition to the common urban risk factors, infant mortality in rural areas was also affected by mode of delivery and adverse life events during pregnancy. The attribution risk of 5-factor general population was as high as 98.07% in 1994. The risk of death from births born by family midwives in rural areas dropped drastically in the recent decade, with an odds ratio of 4.1450 in 1984 and not selected as a multivariate model in 1994.
