Behavioral gender differences across Pre-School Children with Autism Spectrum Disorders: a cross-sectional study.

This study looked at 56 preschool children with autism to see if boys and girls show different autism behaviors. Researchers found that boys and girls differed significantly in repetitive behaviors, especially among children who don't have unusual responses to sounds, textures, or other sensations, and among children with limited speaking ability. This adds to growing evidence that autism may look different in girls compared to boys.

This cross-sectional study examined behavioral differences between boys and girls with Autism Spectrum Disorder (ASD) in 56 preschool children using the Autism Diagnostic Interview Revised. Researchers investigated verbal abilities, unusual sensory interests, and echolalia to identify sex-based differences in ASD presentation. The study found significant gender differences in restricted and repetitive behaviors (p < 0.01), particularly among children without unusual sensory interests (p < 0.05) and those with minimal verbal abilities (p < 0.05). These findings contribute evidence for phenotypical differences in how ASD presents in preschool-aged boys versus girls, supporting growing literature suggesting sex-specific manifestations of autism.

Results suggest clinicians should consider gender-specific presentations when assessing preschool children for autism. Different manifestations of restricted and repetitive behaviors between boys and girls may require tailored diagnostic criteria and intervention approaches, particularly for children with limited verbal abilities or without obvious sensory issues.

Small sample size of 56 children limits generalizability. Cross-sectional design prevents understanding of developmental trajectories. Study relies on single assessment tool (ADI-R). Specific details about the nature of gender differences are not provided in the abstract.

There is increasing literature showing that the presentation of Autism Spectrum Disorder (ASD) could be different according to the sex of the patient. Through the analysis of the Autism Diagnostic Interview Revised interview results of a study group consisting of 56 preschool children diagnosed with ASD potential differences in the presentation of ASD were searched. Variables investigated were verbal abilities, the presence/absence of unusual sensory interests, as well as of echolalia. The results showed significant differences between gender in restricted and repetitive behavior (p < 0.01), in particular for those children who have no unusual sensory interest (p < 0.05) and with minimal verbal ability (p < 0.05).

The findings contribute providing evidences on phenotypical differences in preschool children with a diagnosis of Autism Spectrum Disorder.
