Abstract

Abstract: A family history of psychiatric diseases was suggested as one risk factor for autism spectrum disorders (ASD). Our aim was to assess the association of paternal and maternal diagnosis of psychiatric disorders with the risk of ASD in offspring in Taiwan. We conducted a population-based case-control study. Using several linked national databases, we obtained 1, 000, 939 singleton birth records born between 2004 and 2008. We followed these children up to 2015 for cases of ASD, using diagnostic codes in the National Health Insurance databases. There were 8, 933 ASD cases and each case was matched to ten controls by sex and year of birth. We extracted their parental diagnosis of psychiatric disorders and performed conditional logistic regression models to assess the association of interest. Our sample included 8, 933 cases and 89, 330 controls. Eighty-six percent of the sample were boys. After adjustment for parental age, family income, and urbanization, we found that parental psychiatric diseases were significantly associated with ASD, including schizophrenic and psychotic disorders, mood, anxiety and personality disorders, with adjusted odds ratios ranging from 1.32 to 2.39. Notably, the effect estimates were all larger for maternal diagnosis than paternal diagnosis when stratified by mothers or fathers. Cases of ASD are more likely to be born to parents with psychiatric disorders than their counterparts. Maternal psychiatric diagnosis seems to have a larger influence than paternal diagnosis. Both genetics and maternal environmental factors may contribute to the association observed between parental psychiatric diseases and child ASD. Highlights: The Taiwan registry system allowed data inter-linkage to demonstrate this large, population-based study with enough power to distinguish between the psychiatric history among mothers versus fathers in relation to autism spectrum disorder (ASD). Parental psychiatric diseases were significantly associated with ASD, including schizophrenic and psychotic disorders, mood, anxiety and personality disorders, with adjusted odds ratios ranging from 1.32 to 2.39. With clear temporality between exposure (parental psychiatric disorders) and outcome (offspring ASD), the effect estimates were all larger for maternal diagnosis than paternal diagnosis when stratified by mothers or fathers.
