Genetic liability for neurodevelopmental conditions increased the risk for many pregnancy-related factors, according to study results published in JAMA Psychiatry. Investigators from the Norwegian Institute of Public Health sourced data from the Norwegian Mother, Father and Child Cohort Study (MoBa) which was a population-based pregnancy cohort study conducted between 1999 and 2008. Mothers (n=14,539) and fathers (n=14,897) gave blood samples to evaluate polygenetic scores (PGS) for attention-deficit/hyperactivity disorder (ADHD), autism, and schizophrenia. Genetic liabilities for neurodevelopmental conditions were related with pregnancy-related measures.
