Autism spectrum disorder (ASD) is a developmental disorder characterised by deficits in social interactions and communication, with stereotypical and repetitive behaviours. Recent evidence suggests that maternal immune dysregulation may predispose offspring to ASD. Independent samples t-tests revealed downregulation of IL-17A concentrations in…

Mother-child emotion-related conversations, as a practice of parental socialization of emotion, can help children with autism spectrum disorder (ASD) develop socio-emotional skills. This study intends to explore relationships between mother-child conversations about emotions and socio-emotional skills of children with ASD by accounting for the…

The association of autism spectrum disorder (ASD) with self-reported maternal cannabis use from 3 months pre-conception to delivery ("peri-pregnancy") was assessed in children aged 30-68 months, born 2003 to 2011. Children with ASD (N = 1428) were compared to children with other developmental delays/disorders (DD, N = 1198) and…

Opioid use during pregnancy is associated with suboptimal pregnancy outcomes. Little is known about child neurodevelopmental outcomes. We examined associations between maternal opioid prescriptions preconception to delivery (peri-pregnancy) and child's risk of ASD, developmental delay/disorder (DD) with no ASD features, or ASD/DD with autism…

Parents of a child with autism spectrum disorder (ASD) face specific challenges in parenting, but concrete parenting behavior has never been properly investigated in these families. This exploratory questionnaire study compared parenting behaviors among mothers of children and adolescents with ASD (n = 552) and without ASD (n = 437) and examined…

Gender dysphoria (GD) and autism spectrum disorder (ASD) are associated. In 49 GD children (40 natal males), we examined ASD risk factors (i.e., birth weight, parental age, sibling sex ratio) in relation to autistic traits. Data were gathered on autistic traits, birth weight, parents' ages at birth, sibling sex ratio, gender nonconformity, age,…

We evaluated social anxiety (SA) symptoms in parents of children with autism spectrum disorders (ASDs; N = 131) and community parents (N = 597) using the Social Phobia and Anxiety Inventory (SPAI). SA was significantly more common in ASD than control mothers (15.6 vs. 6.7 %) and more equal between the ASD and control fathers (3.3 vs. 4.8 %). The…

It is not known whether reproductive factors early in the mother's life influence risk of autism spectrum disorders (ASD). We assessed maternal age at menarche, menstrual cycle characteristics during adolescence, oral contraceptive use prior to first birth, body shape, and body mass index (BMI) in association with ASD using binomial regression in…

To identify possible early signs of autism spectrum disorder (ASD) within the Danish National Birth Cohort, we studied prospectively collected interviews from 76,441 mothers about their children's development and behaviour at 6 and 18 months. In Danish national registries, 720 children with ASD and 231 children with intellectual disability (ID)…

The purpose of the study was to compare the level of sense of coherence (SOC) in parents of children with autism and in parents of typically developing children, and to examine the association between SOC level and coping strategies. Two questionnaires were used: Sense of Coherence Scale (SOC-29) and Ways of Coping Questionnaire. Parents of…

Mothers of children aged 2-12 years completed an exhaustive questionnaire assessing feeding and eating behaviors for both themselves and their children with autism, and typically developing siblings of children with Autism Spectrum Disorder (where available), or typically developing children with no sibling with a disability. Results indicate that…

This study interviewed 39 mothers of young children with autism of whom 19 reported their children had experienced developmental regression, especially in verbal and non-verbal communication and social skills. Mean age of regression was 24 months. There was little difference between children who regressed and those who did not in maternal…

Symptoms of Autism Spectrum Disorders (ASD) begin to manifest during the first 2 years; there is limited evidence regarding type and timing of symptom onset. We examined factors related to parental age of recognition (AOR) of early abnormalities and the association between AOR and diagnosis and levels of functioning at 2 and 4 years in 75 toddlers…
