摘要
为了探讨宁夏农村婴儿死亡的主要影响因素,作者拟对吴忠市农村1989～1990年死亡的全部婴儿进行1:1配对的病例对照研究。采用条件 Logistic 回归摸型拟合。结果表明:出生体重、初检孕周、添加辅食时间、近亲结婚等对婴儿死亡有直接作用;父亲受教育年限、喂养方式、胎次、怀孕间隔时间等可通过中间环节对婴儿死亡产生间接影。
A 1:1 matched case-control study was conducted to investigate the main risk factors on infant death from 1989—1990 in the countryside of WuZhong Town.Conditional Logistic regression was used to control con- founding factors.The results show that the direct risk factors on infant de- aths are birth weight,the gestational period at the 1st pre-labour exami- nation,the time of adding auxiliary food,and close relative marriage;in addition,the following factors are of indirect effect on infant deaths, such as the educational level of its father,feed method,oder of the in- fant,and the interval between gestations etc.
