Epidemiological study reveals diagnostic criteria significantly alter infantile autism prevalence in children, highlighting limitations of rigid classification systems.

Key Points

To determine the epidemiological prevalence of infantile autism in children aged 5–9 and evaluate the diagnostic impact of using broad operational criteria compared to DSM-III-like criteria.
Assessed infantile autism prevalence among children aged 5–9 years in the Rhône department of France.
Compared identification rates between broad operational diagnostic criteria and stricter criteria aligned with DSM-III.
Prevalence of infantile autism was 10.8 per 10,000 with broad operational criteria and dropped to 5.1 per 10,000 under DSM-III-like criteria.
Boy-to-girl sex ratios were 2.1:1 using broad operational criteria and 2.3:1 using DSM-III-like criteria.
DSM-III criteria failed to capture a wider spectrum of early polymorphous autistic-like psychotic conditions, though subdividing by major neurological anomalies showed preliminary promise.
