Relationship between parental autistic traits and parenting difficulties in a Japanese community sample

Parenting behaviors in mice: Olfactory mechanisms and features in models of autism spectrum disorders

Rodents, along with numerous other mammals, heavily depend on olfactory cues to navigate their social interactions. Processing of olfactory sensory inputs is mediated by conserved brain circuits that ultimately trigger social behaviors, such as social interactions and parental care. Although innate, parenting is influenced by internal states, social experience, genetics, and the environment, and any significant disruption of these factors can impact the social circuits. Here, we review the molecular mechanisms and social circuits from the olfactory epithelium to central processing that initiate parental behaviors and their dysregulations that may contribute to the social impairments in mouse models of autism spectrum disorders (ASD). We discuss recent advances of the crucial role of olfaction in parental care, its consequences for social interactions, and the reciprocal influence on social interaction impairments in mouse models of ASD.

Prenatal, perinatal and parental risk factors for autism spectrum disorder in China: a case- control study

BACKGROUND

Autism spectrum disorder (ASD) is heritable neurodevelopmental disorders (NDDs), but environmental risk factors have also been suggested to a play a role in its development. Prenatal, perinatal and parental factors have been associated with an increased risk of ASD in children. The aim of the present study was to explore the prenatal, perinatal, and parenting risk factors in children with autism spectrum disorder (ASD) from Beijing, China by comparing them with typically developing (TD) children.

METHODS

A sample of 151 ASD children's parents who from rehabilitation institutions in Beijing were enrolled in this study, and an additional 151 children from kindergartens in Beijing were recruited as a control group (child age: mean = 4.4 years). TD children were matched according to age, sex and maternal education. We explored the maternal AQ (Autism Spectrum Quotient) scores (mean:19.40-19.71, no significant difference between two groups) to referring the genetic baseline. This study evaluated 17 factors with unadjusted and adjusted analyses.

RESULTS

Birth asphyxia was associated with a more than a thirteen-fold higher risk of ASD (adjusted odds ratio (AOR) = 13.42). Breastfeeding difficulties were associated with a higher risk of ASD(AOR = 3.46). Parenting influenced the risk of ASD, with low responding (LR) and harsh or neglectful parenting associated with a higher risk of ASD in offspring (AOR = 2.37 for LR, AOR = 3.42 for harsh parenting and AOR = 3.01 for neglectful parenting). Maternal fever during pregnancy was associated with a higher risk of ASD in offspring (AOR = 3.81).

CONCLUSIONS

Many factors were associated with ASD in offspring. Further assessment is needed to elucidate the role of modifiable environmental factors to inform prevention strategies.

Association between maternal parenting styles and behavioral problems in children with ASD: Moderating effect of maternal autistic traits

Background

Children with autism spectrum disorder (ASD) are at high risk of experiencing externalizing and internalizing problems. This study aimed to reveal how maternal parenting styles and autistic traits influence behavioral problems in children with ASD.

Methods

This study recruited 70 2-5 years children with ASD and 98 typically developing (TD) children. The Parental Behavior Inventory (PBI) and Autism Spectrum Quotient (AQ) were used to collect the maternal parenting styles and autistic traits, respectively. The children's behavioral problems were reported by the mothers using the Strengths and Difficulties Questionnaire (SDQ). Hierarchical moderated regression analyses were used to determine whether maternal autistic traits moderated the association between parenting style and behavioral problems in the children.

Results

Compared to TD children, children with ASD exhibited more severe externalizing and internalizing problems (t = 4.85, p < 0.01). The ASD group scored lower in the maternal supportive/engaged parenting style than the TD group (t = 3.20, p < 0.01). In the TD group, the maternal AQ attention switching domain was positively correlated with internalizing problems in the children (β = 0.30, p = 0.03). In the ASD group, hostile/coercive parenting style was significantly correlated with externalizing problems in the children (β = 0.30, p = 0.02), whereas maternal AQ attention switching domain was negatively correlated with externalizing problems (β = -0.35, p = 0.02). Moreover, the maternal AQ attention switching domain moderated the association between hostile/coercive parenting style and children's externalizing problems (β = 0.33, p = 0.04).

Conclusion

Among ASD children, a hostile/coercive parenting style can increase the risks of children's externalizing problems, especially in the context of high levels of maternal attention-switching problems. Hence, the current study has important implications for the clinical practice of early family-level interventions for children with ASD.
