ABSTRACT

Objective@#To learn the characteristics of drowning deaths and potential years of life lost（PYLL）among residents in Zhoushan，and to provide basis for formulating drowning prevention and control measures. @*Methods@#The death surveillance data in Zhoushan from 2009 to 2018 were collected from Zhejiang Chronic Disease Surveillance Information Management System. Demographic features，causes of drowning，life and labor lost due to drowning were analyzed through indicators such as mortality，standardized mortality，early death index，PYLL and working potential years of life lost（WPYLL）. @*Results@#The crude and standardized drowning mortality of Zhoushan residents were 7.97/100 000 and 4.68/100 000. The drowning mortality showed a decreasing trend from 2009 to 2018（P<0.05）. The mortality of drowning in males was 8.03/100 000，which was higher than 1.33/100 000 in females（P<0.05）. Totally 322 deaths from drowning were fishery workers，accounting for 41.44%. The main cause of drowning death in residents aged 0-14 years，15-29 years and 65 years or above was accidental fall，accounting for 36.11%（13 cases），23.91%（11 cases）and 14.40%（47 cases），respectively. The main cause of drowning death in residents aged 30-44 years and 45-64 years was ship accident，accounting for 33.33%（58 cases）and 36.01%（130 cases），respectively. PYLL and WPYLL caused by drowning death were 22 511 and 11 911 person-years，of which residents aged 30 to 64 years were accounted for 73.33% and 70.55%. The early death index was 28.97. @*Conclusion@#Drowning mortality in Zhoushan showed an downward trend from 2009 to 2018. Men and fishery workers are at higher risk of death from drowning.
