Sex Differences in Autism Spectrum Disorder: Evidence from a Large Sample of Children and Adolescents / William MANDY in Journal of Autism and Developmental Disorders, 42-7 (July 2012)

SKUSE, Auteur Année de publication : 2012 Article en page(s) : p.1304-1313 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Pervasive developmental disorder  Sex differences  High-functioning  Comorbidity Index. décimale : PER Périodiques Résumé : Sex differences have been found amongst toddlers and young children with autism spectrum disorder (ASD). We investigated the presence and stability of these ASD sex differences throughout childhood and adolescence. Participants (N = 325, 52 females; aged 3–18 years) consecutively received an ASD diagnosis at a clinic for assessing high-functioning ASD (mean verbal IQ = 92.6). There were no IQ sex differences. By parent report and direct observation, females had less repetitive stereotyped behaviour (RSB), with male-equivalent levels of social and communication impairment. Teachers reported males with ASD as having greater externalising and social problems than females. The female phenotype we describe was stable across our sample’s age range. Their milder RSBs and less severe difficulties at school may lead to under-recognition of ASD in females.

Sex Differences in Children with Autism Spectrum Disorder Identified Within a High-Risk Infant Cohort / Lonnie ZWAIGENBAUM in Journal of Autism and Developmental Disorders, 42-12 (December 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-12 (December 2012) . - p.2585-2596 Titre : Sex Differences in Children with Autism Spectrum Disorder Identified Within a High-Risk Infant Cohort Type de document : texte imprimé Auteurs : Lonnie ZWAIGENBAUM, Auteur ; Susan E.

Participants included 319 high-risk siblings and 129 low-risk controls. Eighty-five siblings were diagnosed with ASD, including 57 of 176 boys (32.4 %) and 28 of 143 girls (19.6 %), implying a relative odds of ASD of 1.65 in boys versus girls. There were modest sex differences on cognitive and adaptive skills and ASD symptom severity at age 3, but differences between boys and girls with ASD mirrored those in the non-ASD groups. The lower than expected male-to-female ratio, and the relatively high cognitive level among diagnosed children, suggest that we have identified an unanticipated number of higher-functioning girls with ASD.

Sex differences and implications in outcome in children and adolescents at clinical high risk for psychosis / Jordina TOR in Journal of Child Psychology and Psychiatry, 66-10 (October 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-10 (October 2025) . - p.1461-1472 Titre : Sex differences and implications in outcome in children and adolescents at clinical high risk for psychosis Type de document : texte imprimé Auteurs : Jordina TOR, Auteur ; Inmaculada BAEZA, Auteur ; Xavier ALVAREZ-SUBIELA, Auteur ; Marta RODRIGUEZ-PASCUAL, Auteur ; Daniel MUÑOZ-SAMONS, Auteur ; Anna SINTES-ESTEVEZ, Auteur ; Elena DE LA SERNA, Auteur ; Olga PUIG, Auteur ; Gisela SUGRANYES, Auteur ; Daniel ILZARBE, Auteur ; Josep Maria HARO, Auteur ; Montserrat DOLZ, Auteur Article en page(s) : p.1461-1472 Langues : Anglais (eng) Mots-clés : Sex differences  clinical high risk for psychosis  children and adolescents  psychosis  outcome Index. décimale : PER Périodiques Résumé : Background Sex differences have been identified in young adults along the psychosis continuum, but studies in children and adolescents are scarce. This study aimed to evaluate possible sex differences in clinical characteristics and outcomes in children and adolescents with clinical high risk for psychosis (CHR). Methods A naturalistic longitudinal cohort study assessed sociodemographics, CHR symptoms, functioning, and mood at baseline and at 18 months' follow-up in 221 CHR participants (154 females and 67 males) and 159 controls (93 females and 66 males). Regression analyses were performed to test baseline differences, and multinominal regression was used to test the implication of sex in outcome. Results Despite initial pairwise differences in attenuated positive symptoms, regression analyses failed to show sex differences in CHR symptoms when control group was added to the analyses. The interaction between sex and group significantly predicted depressive symptoms (B 2.907, p .040, 95% CI: [ 5.681, 0.133]) and caffeine use lifetime (OR 0.36, 95% CI: [0.138, 0.924], p .034). A significant interaction between age and sex showed that the older the age in females, the greater the probability of non-remission of CHR at follow-up, as compared to males (B 0.338, IC 95%: [0.123, 0.933], p .036), but no relevant associations with sex were found in psychosis outcome. Conclusions No sex-related differences in CHR symptoms were observed in a CHR children and adolescent population. Outcomes related to non-remission of CHR state in older females could reflect the greater prevalence of psychosis-like experiences in adolescent females. These results invite us to reconsider the usefulness of the current CHR criteria in young populations, especially if we do not take into account a gender perspective and how age might affect it.

Sex differences in age of diagnosis of autism spectrum disorder: Preliminary evidence from Uganda / Emmanuel BONNEY in Autism Research, 15-1 (January 2022)  

Public ISBD [article]  inAutism Research > 15-1 (January 2022) . - p.183-191 Titre : Sex differences in age of diagnosis of autism spectrum disorder: Preliminary evidence from Uganda Type de document : texte imprimé Auteurs : Emmanuel BONNEY, Auteur ; Catherine ABBO, Auteur ; Collin OGARA, Auteur ; Michele E.

A retrospective chart review was performed and demographic as well as clinical data were collected from children with ASD diagnoses who attended two mental health clinics in Uganda between 2014 and 2019. Descriptive statistics such as percentages, means, and standard deviations were used to summarize the data. Independent t-test was also performed to determine differences in the mean age of diagnosis between males and females. Two hundred and thirty-seven (156 males, 81 females) children with ASD were identified. The average age of ASD diagnosis was (6.9 ± 4.0) years. A statistically significant difference in age of ASD diagnosis was found between males and females (t = -2.106, p = 0.036), such that on average females received a diagnosis at least 1 year later than males. Of the 237 participants, 53.6% were identified with ASD only, 16.0% had ASD and ADHD, 10.5% were diagnosed with ASD and epilepsy, and 7.2% had a diagnosis of complex ASD. The results confirm delays in access to ASD diagnosis and suggest that females are more likely to receive a ASD diagnosis later than males within the Ugandan context. ASD awareness should be intensified to improve public or professional knowledge about ASD to enhance early identification in Uganda.

Sex differences in Arab children with Autism spectrum disorders / Mostafa AMR in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)

A total of 37 boys and 23 girls recruited from three Arab countries (Egypt, Saudi Arabia, Jordan) matched for age and IQ. They were compared using Indian Scale for Assessment of Autism (ISAA) and the Child Behavior Checklist (CBCL). The boys had poor emotional responsiveness and the girls had more cognitive problems. With regard to coexisting psychopathology boys exhibited significantly more delinquent behavior problems. Longitudinal, representative studies are needed to elucidate etiological significance of the observed sex differences.
