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.
ABSTRACT
Objective@#To investigate the trends in mortality of injury among elderly populations at ages of 60 years and greater in Huzhou City from 2010 to 2020, so as to provide the evidence for proposing preventive and control interventions of injury among the elderly.@*Methods @#The death of injury among registered residents at ages of 60 years and older in Huzhou City from 2010 to 2020 were collected from Zhejiang Provincial Information Management System for Chronic Disease Surveillance. The mortality and main causes of injury were descriptively analyzed among the elderly, and the trends in mortality were analyzed using annual percent change ( APC ).@*Results@#Totally 13 360 deaths occurred due to injury among elderly populations in Huzhou City from 2010 to 2020, and the mortality of injury appeared a tendency towards a rise with years ( APC=3.87%, P<0.05 ). The annual mean mortality and standardized mortality of injury were 199.89/105 and 192.68/105 among elderly populations in Huzhou City from 2010 to 2020. The overall mortality of injury was higher in men than in women during the period from 2010 to 2017, and higher mortality was seen in women than in men in 2020 ( P<0.05 ). The injury mortality in men and in women, and the overall mortality of injury all appeared a tendency towards a rise with ages ( P<0.05 ). The five most common causes of injury included fall ( 82.89/105 ), motor vehicle traffic accidents ( 26.45/105 ), suicide ( 18.52/105 ), drowning ( 16.88/105 ) and shipping accidents except motor vehicle ( 13.77/105 ), which accounted for 79.30% of all deaths due to injury. The mortality of fall in women ( APC=8.87%, P<0.05 ) and the overall mortality of fall ( APC=10.63%, P<0.05 ) both appeared a tendency towards a rise with years.@*Conclusion@#The mortality of injury appeared a tendency towards a rise and increased with ages among the elderly in Huzhou City from 2010 to 2020. Fall is the leading cause of death due to injury among the elderly.
