Abstract: 【Objective】 To monitor the changing trend of infant mortality rate (IMR) in Luwan district Shanghai, observe how IMR affected average life expectancy, in order to take proper measures to reduce the rate. 【Method】 Dynamic series analysis was used to analyze monitoring data of 194 195 cases of live birth, 2 379 cases of infant death in Luwan district Shanghai during 1961—2008. 【Results】 The infant mortality rate and neonatal mortality rate were 25.20‰ and 8.98‰ respectively in 1961.Through intervention,they were reduced to 1.64‰ and 1.64‰ respectively in 2008. The decline speed were 93.50% and 81.76% respectively, which had significant effects on the average life expectancy and death structure. The four leading causes of IMR were congenital malformation, pneumonia, preterm infant and birth trauma and asphyxia. 【Conclusions】 Along with the development of the medical profession in Luwan district, their great effort have been taken to reduce the infant mortality rate. Now we should lay stress on monitoring birth defects and advocate perinatal health care, in order to reduce the IMR and increase the average life expectancy effectively.
