Global and regional insights: unravelling the epidemiological factors and burden of autism spectrum disorders with a focus on China from 1990 to 2021
Clinical Report: Analyzing the Epidemiological Factors of Autism in China
Background
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social communication and behavior. The increasing prevalence of ASD globally highlights the need for understanding its epidemiological trends. In China, the long-term trends and future projections of ASD prevalence and burden remain critical for public health planning and resource allocation.
Data Highlights
Year
Age-Standardised Prevalence (per 100,000)
Age-Standardised DALYs Rate (per 100,000)
2021
Projected: 660.28
Projected: 126.66
Global Average by 2030
793.01
147.43
Key Findings
The age-standardised prevalence of ASD in China was lower than the global average from 1990 to 2021.
The average annual percentage change (AAPC) for prevalence and DALYs in China was 0.22% and 0.23%, respectively, higher than global averages.
By 2030, the prevalence of ASD in China is projected to reach 660.28 per 100,000.
There is a strong positive correlation between ASD prevalence and sociodemographic index (SDI) across countries.
ASD significantly contributes to health loss, particularly among preschool boys.
The health impact of ASD has been increasing over the past three decades.
Clinical Implications
The rising burden of ASD in China necessitates targeted prevention and control measures, especially for high-risk groups such as preschool-aged boys. Public health strategies must be informed by these epidemiological trends to effectively allocate resources and improve outcomes.
Conclusion
The findings indicate a concerning upward trend in the burden of ASD in China, emphasizing the need for urgent public health interventions. Continued monitoring and research are essential to address the growing impact of ASD.
Systematic review of 8 observational studies found limited evidence on associations between prenatal asthma-medication exposure and neurodevelopmental outcomes, with autism spectrum disorder the only outcome suitable for meta-analysis.
