INTRODUCTION: Sleep disorders are frequently reported in individuals with anorexia nervosa (AN). Autism spectrum disorder (ASD) is strongly associated with both anorexia nervosa and sleep disturbances. We study the possible influence of the association of ASD to AN to the development of sleep disorders.
METHOD: A retrospective cohort study design was used, including all patients followed for AN or ASD in the child and adolescent psychiatric unit at the Salvator hospital, Marseille, between January 2019 and January 2024. We had included 491 patients, mean age was 15.16 years ± 3.11 years. Sleep was assessed with the PSQI, ESS and ISI; autistic traits with the Autism-Spectrum Quotient (AQ).
RESULTS: Sleep disorders were significantly more prevalent in the anorexia nervosa binge/purge subtype group than the Anorexia nervosa restrictive subtype or the ASD groups with pathological scores in the PSQI in 78% (p < 10-3), ISI in 46.3% (p = 0.035) and in the ESS in 58.5% (p = 0.017). The prevalence of sleep disorders was significantly higher in AN patients having pathological AQ score. However, when controlling for confounding factors, this association was no more significant.
CONCLUSION: Our findings were inconclusive in establishing a clear association between autistic traits and sleep disorders in individuals with anorexia nervosa. However, a potential influence cannot be ruled out.
