Abstract
Background: To evaluate the association between maternal MVCs during pregnancy and neurodevelopmental disorders (NDDs, including intellectual disability, ADHD, ASD, and infantile cerebral palsy) in children.
Methods: This population-based cohort of live births in Taiwan was analyzed, comparing children born to mothers involved in MVCs during pregnancy with those without such exposure. Children were linked to the insurance database to identify the possible diagnosis of NDDs. The Cox proportional hazards regression model was used to estimate the relative hazards.
Results: A total of 19,277 children with maternal MVCs and 76,015 children without exposure were included. Children exposed to maternal MVCs during the first two trimesters or whose mothers sustained mild to severe injuries showed a higher risk of intellectual disability. Severe maternal injuries also increased the risk of infantile cerebral palsy (aHR = 3.86; 1.27-11.78). MVCs in the third trimester, or mild maternal injuries, were associated with a higher risk of ASD (third trimester: aHR = 1.40; 1.04-1.87; mild injuries: aHR = 1.38; 1.09-1.74).
Conclusion: Children exposed to maternal MVCs with severe injuries had a higher risk of intellectual disability and cerebral palsy. Third-trimester exposure may increase the risk of ASD. However, these findings should be interpreted cautiously as genetic factors may contribute to the observed association.
Impact: There is some evidence linking maternal MVCs during pregnancy to the development of neurodevelopmental disorders in children. Children of mothers with severely injured were more likely to suffer from infantile cerebral palsy and intellectual disability. The risk of autism spectrum disorder is higher in children whose mothers are involved in MVCs during the late stage of pregnancy, and there is also an increased risk of intellectual disability during the first two trimesters.
期刊介绍:
Pediatric Research publishes original papers, invited reviews, and commentaries on the etiologies of children''s diseases and
disorders of development, extending from molecular biology to epidemiology. Use of model organisms and in vitro techniques
relevant to developmental biology and medicine are acceptable, as are translational human studies
