Rationale: This study assesses the association between prenatal exposure to antiseizure medication (ASM) and birth weight outcomes.

Methods: The study combined information from population-based registers of children born in Denmark, Finland, Iceland, Norway, and Sweden between 1996 and 2017 (the SCAN-AED project). We used linear regression to study the association between prenatal monotherapy exposure to ASMs and birth weight in gram (g), and logistic regression to estimate adjusted odds ratios (aOR) for the association with low birth weight ( < 2,500 g) and small for gestational age. We defined small for gestational age as children with a z-score for birth weight according to sex, country, and gestational week at birth < 10% percentile. Estimates were adjusted for potential confounding factors, including maternal age, smoking, substance abuse, cohabitation, income, education, parity, maternal psychiatric disorders and epilepsy, and for maternal use of psychotropic medication. Analyses of birth weight and low birth weight ( < 2,500 g) were also adjusted for gestational age.
