Langues : Anglais (eng) Mots-clés : Male  Infant  Pregnancy  Female  Humans  Autistic Disorder/diagnostic imaging  Brain/diagnostic imaging  Gestational Age  Autistic traits  Early brain development  Q-chat  Transcerebellar diameter  Ultrasound Index. décimale : PER Périodiques Résumé : BACKGROUND: Structural differences exist in the brains of autistic individuals. To date only a few studies have explored the relationship between fetal brain growth and later infant autistic traits, and some have used fetal head circumference (HC) as a proxy for brain development. These findings have been inconsistent. Here we investigate whether fetal subregional brain measurements correlate with autistic traits in toddlers. METHODS: A total of 219 singleton pregnancies (104 males and 115 females) were recruited at the Rosie Hospital, Cambridge, UK. 2D ultrasound was performed at 12-, 20- and between 26 and 30 weeks of pregnancy, measuring head circumference (HC), ventricular atrium (VA) and transcerebellar diameter (TCD). A total of 179 infants were followed up at 18-20 months of age and completed the quantitative checklist for autism in toddlers (Q-CHAT) to measure autistic traits. RESULTS: Q-CHAT scores at 18-20 months of age were positively associated with TCD size at 20 weeks and with HC at 28 weeks, in univariate analyses, and in multiple regression models which controlled for sex, maternal age and birth weight. LIMITATIONS: Due to the nature and location of the study, ascertainment bias could also have contributed to the recruitment of volunteer mothers with a higher than typical range of autistic traits and/or with a significant interest in the neurodevelopment of their children. CONCLUSION: Prenatal brain growth is associated with toddler autistic traits and this can be ascertained via ultrasound starting at 20 weeks gestation.

Is the association between mothers' autistic traits and childhood autistic traits moderated by maternal pre-pregnancy body mass index? / Alexandros TSOMPANIDIS ; Rama J.

Langues : Anglais (eng) Mots-clés : Pregnancy  Female  Adolescent  Humans  Child, Preschool  Body Mass Index  *Autistic Disorder  Mothers  Parents  Autistic traits  Children  Pre-pregnancy body mass index Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous studies showed that there is a positive association between mothers' and children's autistic traits. We also tested if this association is more pronounced in mothers with a higher pre-pregnancy body mass index (BMI). METHOD: The study was embedded in two cohorts with information available for 4,659 participants from the Generation R and for 179 participants from the Cambridge Ultrasound Siblings and Parents Project (CUSP) cohort. In both cohorts, maternal autistic traits were assessed using the short form of the Autism Spectrum Quotient, and information about maternal height and weight before pregnancy was obtained by questionnaire. Child autistic traits were assessed with the short form of Social Responsiveness Scale in Generation R (M=13.5 years) and with the Quantitative Checklist for Autism in Toddlers (Q-CHAT) in the CUSP cohort (M=1.6 years). RESULT: Higher maternal autistic traits were associated with higher autistic traits in toddlerhood (CUSP cohort; ?(adjusted)=0.20, p<0.01), in early childhood (Generation R; ?(adjusted)=0.19, p<0.01), and in early adolescence (Generation R; ?(adjusted)=0.16, p<0.01). Furthermore, a higher maternal pre-pregnancy BMI was associated with higher child autistic traits, but only in Generation R (?(adjusted)=0.03, p<0.01). There was no significant moderating effect of maternal pre-pregnancy BMI on the association between autistic traits of mothers and children, neither in Generation R nor in CUSP. In addition, child autistic traits scores were significantly higher in mothers who were underweight and in mothers who were overweight compared to mothers with a healthy weight. CONCLUSION: We confirm the association between maternal and child autistic traits in toddlerhood, early childhood, and early adolescence. Potential interacting neurobiological processes remain to be confirmed.

A qualitative exploration of autistic mothers' experiences I: Pregnancy experiences / Sarah HAMPTON in Autism, 27-5 (July 2023)  

Public ISBD [article]  inAutism > 27-5 (July 2023) . - p.1271-1282 Titre : A qualitative exploration of autistic mothers' experiences I: Pregnancy experiences Type de document : Texte imprimé et/ou numérique Auteurs : Sarah HAMPTON, Auteur ; Joyce MAN, Auteur ; Carrie ALLISON, Auteur ; Ezra AYDIN, Auteur ; Simon BARON-COHEN, Auteur ; Rosemary HOLT, Auteur Article en page(s) : p.1271-1282 Langues : Anglais (eng) Mots-clés : autism;healthcare;maternity;motherhood;parenting;pregnancy;sensory processing Index. décimale : PER Périodiques Résumé : Pregnancy may pose a number of physical and healthcare-related challenges for autistic people, who experience differences in sensory processing and can face barriers to accessing healthcare. However, little research has explored autistic pregnancy experiences. Semi-structured interviews were conducted with 24 autistic and 21 non-autistic women during the third trimester of pregnancy. Thematic analysis revealed that the autistic group experienced heightened sensory and physical symptoms during pregnancy compared with the non-autistic group. Autistic participants were sometimes reluctant to disclose their diagnosis to healthcare professionals and felt that professionals lacked autism knowledge. While both groups appreciated clear information about their care, autistic participants further highlighted the need for detailed information and being given time to process verbal information. The autistic group also highlighted the need for sensory adjustments in healthcare settings. The findings indicate ways in which prenatal healthcare can be improved for autistic people, including sensory and communication adjustments. There is a need for greater autism-related training for prenatal healthcare professionals to ensure that autistic people receive appropriate support. Lay abstract Little is known about how autistic people experience pregnancy. We interviewed 24 autistic and 21 non-autistic women during pregnancy to find out about their experiences. Autistic participants had more physical difficulties, such as nausea and pain, during pregnancy than non-autistic participants. They also sometimes felt that healthcare professionals, such as midwives, did not have a good understanding of autism and they did not always feel comfortable telling professionals about their autism diagnosis. Autistic participants told us that they needed professionals to communicate with them clearly and to make changes during appointments such as dimming lights. This research shows that autistic people would benefit from changes to pregnancy appointments and that more training about autism would help maternity care professionals to support autistic people during pregnancy.
