Association between autistic traits and home nurture environment: A community-based study

Background: Increasing attention has been directed toward understanding the ways in which social environmental factors influence children’s behavior, in physical and mental health domains. Autistic traits are continuously distributed in general population and children with autistic traits have great risk of additional mental diseases. However, no literature has demonstrated the relation between autistic traits and home nurture environment. Methods: Caregivers of 408 kindergarten children (68% male) were recruited to complete a series of survey measures in China. The measures used were the Clancy Autistic Behavior Scale and the Home Nurture Environment Scale. Multivariate logistic regression analysis was used to examine the associations. Results: Frequent language/cognition stimulation (aOR 0.520, 95%CI 0.302-0.896), high level of parental warmth (aOR 0.596, 95%CI 0.392-0.905) and high quality of physical living environment (aOR 0.332, 95%CI 0.196-0.561) were the protective factors of autistic traits after controlling the confounding factors. Results were generally not moderated by the child’s gender or birth order. Conclusions: These findings highlight the importance of high levels of home nurture environment for autistic traits and indicate that public health programs should focus on guidance of parents for developing more adequate parenting skills and favorable home nurture environment.
