Compared to other mothers, mothers of children with autism spectrum disorder (ASD) or intellectual disability (ID) have higher rates of treatment episodes for psychiatric disorders. We aimed to estimate the maternal burden of care by comparing the length of hospitalisations for psychiatric disorders and the treatment rates for psychiatric disorders after the birth in mothers of children with ASD/ID and no psychiatric history to that of other mothers with no psychiatric history. Mothers of children with ID of known cause (not Down syndrome) and mothers of children ASD without ID emerged as particularly vulnerable. Mothers of children with Down syndrome were resilient. The development of specialised organisations to provide support to mothers of children with ID of known cause (not Down syndrome) and mothers of children with ASD without ID could assist them to maintain their mental health.

Background: Mothers of a child with autism spectrum disorder have more psychiatric disorders after the birth of their child. This might be because they have more psychiatric disorders before the birth, or the increase could be related to the burden of caring for their child. Aims: We aimed to calculate the incidence of a psychiatric diagnosis in women with no psychiatric history after the birth of their eldest child with autism spectrum disorder compared to women with no child with autism spectrum disorder or intellectual disability and no psychiatric history. Methods: By linking datasets from Western Australian population-based registries, we calculated the incidence of a psychiatric disorder in mothers of children with autism spectrum disorder and compared to mothers of children with no autism spectrum disorder or intellectual disability. Negative binomial regression using STATA 13 was used for all analyses. Results: Apart from alcohol and substance abuse, mothers of children with autism spectrum disorder had higher incidences of all categories of psychiatric disorders than other mothers. Conclusion and implications: The increase of psychiatric disorders in mothers of children with autism spectrum disorder and no psychiatric history compared to similar mothers with no child with autism spectrum disorder or intellectual disability might be due to a pre-existing genetic disposition coupled with an environmental trigger provided by the challenges of raising their children with autism spectrum disorder. In addition, the increased burden borne by the mothers of children with autism spectrum disorder might result in a higher incidence of psychiatric disorders in mothers who are not genetically disposed.
