Epidemiology of Autism Spectrum Disorder in Buenos Aires, Argentina: Insights from Unique Disability ID Issuance Trends

Abstract

Abstract Purpose: Autism Spectrum Disorder (ASD) prevalence rates vary greatly across regions and studies. Some countries, such as Argentina, have unknown rates. Due to this high heterogeneity in ASD prevalence worldwide, it is important to study its prevalence and characteristics in such countries to develop effective policies. Methods: we analyzed official data from the Unique Disability IDs (UDIDs) issued for individuals with ASD in the Autonomous City of Buenos Aires from 2016 to 2021, examining age, gender, and diagnosis. Results: most UDIDs were issued for males, for Pervasive Developmental Disorders, and almost half to individuals over 8 years old, with these trends remaining stable over these years. However, UDID issuance abruptly dropped in 2020. Conclusions: our findings highlight epidemiological aspects of the autism population in Argentina, including challenges such as delayed diagnosis and high prevalence of broad diagnosis categories. Addressing these challenges requires further research and intervention to improve the quality of life of individuals with ASD.
