Trend of disease burden of drowning in Chongqing residents, 2012-2018 / 公共卫生与预防医学

ABSTRACT

Objective To analyze the trend of the mortality and disease burden of drowning in Chongqing and provide suggestions for drowning prevention and control. Methods The information data on drowning deaths in Chongqing (ICD-10 code W65-W74) from 2012 to 2018 were collected. SPSS 25.0 software was used to calculate and analyze indicators such as mortality, age standardized mortality rate by Chinese population (ASMRC), years of life lost with premature death (YLLs), years lived with disability (YLDs), and disability adjusted life years (DALYs). The differences of drowning mortality between male and female, urban and rural areas were tested by Chi-square test. The trend of drowning mortality and disease burden was calculated as annual percent change (APC) using curve-estimation model of logistic regression. The difference of APC was tested by t-test (α=0.05). Results The mortality and ASMRC of drowning decreased from 4.90/100 000 and 4.87/100 000 in 2012 to 3.85/100 000 and 3.59/100 000 in 2018, respectively. The APCs were -3.34% and -4.49%, respectively. There was no significant difference in the change trend (t value 2.34 and 2.42, P>0.05). The mortality of drowning in the male was higher than that in the female (P0.05). Conclusion The mortality and disease burden of drowning in Chongqing showed a decreasing trend, which was lower than the national average level. Children, male and elderly people are the vulnerable population to prevent drowning, and rural areas are the key areas to prevent drowning.
