title: [Analysis of risk factors for infant deaths in urban and rural areas of Shandong Province].
abstract: Data of infant deaths in 1984 and 1994 were collected from the disease surveillance system in Shandong Province and 13 risk factors contributing infant death were analyzed with unconditional logistic regression to reveal their change in urban and rural areas in recent ten years. Results showed that risk factors for infant death in urban areas were birth weight, mother's age of childbirth, length of gestation and maternal health status, with comprehensive population attributable risk proportions (PARP) of 92.24 and 93.81 percent in 1984 and 1994, respectively. In addition to the risk factors mentioned above in urban areas, infant death in rural areas was also affected by ways of delivery and unhealthy events during pregnancy, with a comprehensive PARP of 98.07 percent in 1994. Risks for infant death delivered by family midwives reduced greatly in recent ten years, with an odd ratio (OR) of 4.145 in 1984, but it could not be entered a multivariate regression model in 1994.
