Disease burden of mental disorders among children and adolescents in China from 1990 to 2019: a comparison analysis based on GBD 2019 data

ObjectiveTo compare the disease burden of mental disorders and its changes among children and adolescents in China between 1990 and 2019 to establish strategies for the prevention and control of mental illnesses. MethodsThe data on mental disorders in children and adolescents (0 – 19 years) were collected from the Global Burden of Disease 2019 (GBD2019) database. The burden of these diseases was assessed using indicators such as the number of cases, standardized prevalence, disability-adjusted life years (DALYs), and standardized DALYs rate. Additionally, the difference in disease burden between 1990 and 2019 was estimated through the rate of change and average annual percentage change (AAPC). ResultsThe prevalence, standardized prevalence, DALYs, and standardized DALYs rates of mental disorders in the Chinese population under the age of 20 years in 2019 were recorded as 20.607 million cases, 8611.08/100 000 population, 2.1029 million person-years, and 688.12/100 000 population respectively. In comparison to
