Abstract:
Objective: This study aims to analyze the disease burden of intellectual disability among Chinese children and adolescents aged 0-19 years in 2019 and its trends from 1990 to 2019. Methods: Data were gathered from the Global Burden of Disease study. The prevalence and years lived with disability (YLDs) of intellectual disability among Chinese children and adolescents were compared with the global average by gender, age group, and severity of disability in 2019. Joinpoint regression model was used to analyze the trends in the prevalence and YLDs of intellectual disability among Chinese children and adolescents from 1990 to 2019. Results: The prevalence and YLDs of intellectual disability among Chinese children and adolescents in 2019 were 1 522.65 per 100 000 (95%UI: 1 228.62 per 100 000-1 817.55 per 100 000) and 109.81 per 100 000 (95%UI: 72.15 per 100 000-158.09 per 100 000), respectively, which were lower than the global average. The prevalence and YLDs of severe intellectual disability in China were slightly higher than the global average. The average annual percent changes in the prevalence and YLDs of intellectual disability among Chinese children and adolescents were -0.23% (95%CI: -0.26%--0.21%, P<0.001) and 0.74% (95%CI: 0.66%-0.81%, P<0.001) from 1990 to 2019, respectively. The prevalence and YLDs of severe intellectual disability showed continuously increasing trends over the past 30 years. Conclusions: The disease burden of intellectual disability among Chinese children and adolescents was lower than the global average in 2019, but severe intellectual disability was higher than the global average. The prevalence of intellectual disability among Chinese children and adolescents showed an overall decrease, while YLDs showed an increasing trend from 1990 to 2019.
