Analysis of neurodevelopmental delay in children exposed in utero to hyperemesis gravidarum reveals increased reporting of autism spectrum disorder

摘要

The purpose of this study was to follow up on the reporting of neurodevelopmental disorders in children exposed in utero to Hyperemesis Gravidarum (HG). This was an exploratory descriptive study whereby neurodevelopmental outcomes of 267 children delivered by 177 mothers with HG were compared to neurodevelopmental outcomes from 93 children delivered by 60 unaffected mothers. Similar to at age 8, the children (now 12) exposed in utero to HG had over 3-fold increase in odds of neurodevelopmental disorders including attention, anxiety, sensory, sleep difficulty, and social development delay/social anxiety. However, with the longer follow-up, there was also a significant increase in Autism Spectrum Disorder (ASD), reported in 22/267 (8%) of children exposed to HG in utero and no unexposed children. As early intervention for ASD can be critical to prognosis, larger studies are urgently needed to determine whether ASD is associated with exposure to HG.
