Injury Mortality of Children and Adolescents Aged 0-19 Years - China, 2010-2021

Introduction : To examine the recent trends in child injury mortality in China. Methods : Injury mortality data of 2010-2021 for children and adolescents aged 0-19 years were from the China Health Statistics Yearbook. Injury mortality disparities across urban vs. rural locations, gender, and age groups were scrutinized. Annual percent change (APC), average annual percent change (AAPC), and their 95 % confidence intervals (95 % CI ) were estiamted usimg Joinpoint regression models. Results : The age -standardized injury mortality significantly dropped from 21.87 to 9.41 per 100,000 population among children and youth aged 0-19 years during 2010-2021, with an AAPC of -6.7 % (95 % CI : -8.2 % , -5.2 % ). The urban -rural disparity and gender gap in injury mortality reduced gradually. In 2021, drowning and road traffic crashes were the top two causes of child injury deaths, explaing 31.1 % and 27.9 % of total injury deaths, respectively. Suffocation accounted for 62.3 % of injury deaths among infants younger than a year. Alarmingly, the suicide mortality rate rose from 2.16 to 3.42 per 100,000 population between 2010 and 2021 among teenagers aged 15-19 years. Subgroup analyses yielded similar results. Conclusions : During 2010-2021, the injury mortality decreased significantly among Chinese children and adolescents, and the responding urbanrural disparities narrowed.
