Method The mortality data that reported by health institutions in Xiamen City through the national disease surveillance system during 2007 to 2011 were studied to describe the level and distribution of children under-five mortality. Results Under 5 mortality rate(U5MR) increased with years from 2007 to 2011(χ²_trend=92.68,P<0.01).Mortality rate of neonates,infants,1~ 5 years of ages and children under-five were 1.76‰,3.02‰,1.13‰ and 4.13‰ respectively.The 3 top causes of U5MR were the perinatal period disease(1.40‰),birth defects(0.87‰) and injury(0.44‰) respectively,which together constituted a 65.53% ratio.The difference of U5MR between male(4.81‰) and female(3.42‰) was statistically significant(χ²=23.57,P<0.01).And U5MR in rural(5.59‰) were higher than that in town(3.75‰)(χ²=36.42,P<0.01).Municipal General Hospital was the main medical institutions.
