Abstract

Objective: To analyze the available scientific literature on the prevalence of autism spectrum disorder (ASD), its associated factors, and intervention strategies in children. Method: A bibliographic review with a structured literature search was conducted in PubMed, Scopus, Web of Science, and SciELO. Publications in Spanish and English from 2018 to 2025 were included. Of the 327 records identified, 46 studies were included following duplicate removal, screening, and eligibility assessment. Results and discussion: The studies revealed variability in prevalence estimates according to region, age, sex, population, and case-identification procedures. Associated factors included genetic, prenatal, perinatal, environmental, and epigenetic components, supporting a multifactorial perspective of ASD. Intervention strategies showed favorable outcomes in communication, language, social interaction, cognition, behavior, and adaptive skills, with no single modality demonstrating universal superiority. Conclusion: The reviewed literature supports a multidimensional understanding of ASD, whose interpretation requires consideration of the heterogeneity of populations, identification methods, and intervention characteristics. Longitudinal studies and comparable research designs are needed to strengthen the available evidence.
