Abstract：Objective To investigate the mortality and years of life lost due to drowning in Huzhou City from 2012 to 2021, so as to provide insights into drowning prevention and control. Methods The mortality surveillance data on drowning in Huzhou City from 2012 to 2021 were collected from the Zhejiang Chronic Disease Surveillance Information Management System. The crude mortality and standardized mortality of drowning by the 2010 population census data in 2010, years of potential life lost (YPLL) and working years of potential life lost (WYPLL) due to drowning were calculated. In addition, the annual percent change (APC) was used to analyze the trends in drowning mortality and the rate of YPLL and WYPLL in Huzhou City from 2012 to 2021. Results A total of 1 681 deaths occurred due to drowning in Huzhou City from 2012 to 2021, accounting for 9.11% of total injury deaths. The overall mortality and standardized mortality of drowning were 6.35/105 and 4.70/105, respectively, and mortality and standardized mortality of drowning were 6.95/105 and 5.44/105 in men and 5.76/105 and 3.98/105 in women, respectively. The highest mortality of drowning was found in residents at ages of 65 years and older (16.04/105 to 27.02/105), followed by in residents at ages of less than 5 years (2.54/105 to 16.37/105). The overall mortality of drowning was 5.29/105 to 7.21/105 among residents in Huzhou City from 2012 to 2021, and no significant change tendency was seen (APC=-2.18%, t=-2.085, P=0.071). The standardized mortality of drowning reduced from 6.10/105 to 3.69/105 (APC=-4.88%, t=-4.215, P=0.003). In addition, the YPLL and rate of YPLL, and WYPLL and the rate of WYPLL due to drowning mortality were 22 620.50 person-years, 0.10%, 17 956.50 person-years and 0.08% in Huzhou City from 2012 to 2021, respectively, and the rates of YPLL (APC=-6.95%, t=-3.203, P=0.016) and WYPLL (APC=-7.60%, t=-3.126, P=0.014) both appeared a tendency towards a decline from 2012 to 2021. Conclusions The standardized mortality of drowning and rate of YPLL appeared a tendency towards a decline among residents living in Huzhou City from 2012 to 2021, and residents at ages of 65 years and older and less than 5 years are high-risk populations for management of drowning mortality.
