【Abstract】 Objective To discuss the major causes of the decrement of life span.Methods We analyzed and compared the data applied by the diseases surveillance points (DSPs) in China(1997-1999) by the sequence and the proportion of multiple death cases,the proportion of age specific group of multiple death cases,the sequence of their age medians and tested the significance of age medians at the same time.Results The Chinese first five frequently encountered diseases are circulatory system diseases,tumors,respiratory system diseases,accidental death and digestive system diseases in sequence,which occupied the 85 67% of the total.All the maximal proportion of the diseases lied in the age specific group of 60～ except the accidental death whose one lied in the group of 15～59.All the minimal proportion of them lied in the age specific group of 0～14 except the respiratory system diseases,whose one lied in the group of 15～59.There were remarkably significance between the age medians by multiple comparison except the tumor and digestive system diseases(P<0 01).Conclusion Accidental death is a major cause in the decrement of life span in recent years,and the proper preventible measures should be timely taken to make our people live longer.At the same time,we should pay more attention to the tumors and digestive system diseases.更多还原
