Surveillance for death causes in residents in Yuyao, Zhejiang, 2014–2017

ObjectiveTo understand the epidemiological characteristics of deaths in residents in Yuyao, Zhejiang province, and provide scientific evidence for the prevention and control of injury.

MethodsThe death surveillance data in residents in Yuyao from 2014 to 2017 were collected and the death causes were classified according to the International Classification of Diseases, 10^th edition (ICD-10). The average mortality rate, standardized average mortality rate, potential years of life lost (PYLL), average years of life lost (AYLL) and the rate of PYLL were calculated.

ResultsFrom 2014 to 2017, the average mortality rate was 739.95/100 000, and the standardized average mortality rate was 435.49/100 000. The average annual crude mortality rate was 832.53/100 000 and the standardized mortality rate was 484.60/100 000 for males. The average annual crude mortality rate was 649.51/100 000 and the standardized mortality rate was 386.28/100 000 for females. The overall mortality rate of males was higher than that of females (χ²＝381.589, P＜0.001); The first five death causes were malignant tumor (234.41/100 000), respiratory disease (136.09/100 000), cerebrovascular disease (99.82/100 000), heart disease (90.47/100 000) and injury (74.33/100 000). The death caused by the first 5 death causes accounted for 85.84% of the total. For the first 5 death causes, the PYLL was 79 305.00 person years, the average PYLL was 13.01 person years, and the rate of PYLL was 26.49‰. Injury caused greatest loss of life.

ConclusionMalignant tumor was one of leading causes of deaths in Yuyao, causing great loss of life expectancy. The overall mortality rate of males was higher than that of females. Comprehensive disease control measures should be taken for different groups of people.
