Key Points

The aim was to estimate the prevalence of neurodevelopmental disorders (NDDs) among preschool children of migrants and refugees in high-income Western countries.
Conducted a systematic review and meta-analysis using five databases for eligible studies until October 1, 2025.
Screened and selected studies independently by three reviewers, followed by data extraction and quality assessment.
Estimated weighted pooled prevalence of autism using random-effects meta-analysis.
Weighted pooled prevalence of autism was 28% (95% CI: 24% - 33%) based on cross-sectional data.
Prevalence ranges for other NDDs included motor/coordination 4.6–29.8%, speech/language 5.8–18.2%, and impaired vision/hearing at 19.8%.
Autism co-occurring with intellectual disability ranged from 0.22% to 19.20%.
