Abstract

Background and aims: Sparse data exist on the risk of adverse pregnancy outcomes in women with familial hypercholesterolemia (FH). We investigated associations between FH and adverse pregnancy outcomes, and between statin exposure in pregnancy and adverse pregnancy outcomes among women with FH.

Methods: We studied 3869 pregnancies among 1869 women with genetically-proven FH and 68225 pregnancies among 33661 women from the general population. Data on adverse pregnancy outcomes were obtained during 1967-2018 from the Medical Birth Registry of Norway. Data on pharmacy-dispensed statins were obtained from the Norwegian prescription database (2004-2018) in 1051 women with FH. Associations were presented as odds ratio (OR) with 95 % CI from logistic regression adjusted for mother's age, parity, and offspring's birth year.

Results: Women with FH had a higher risk of preeclampsia (OR 1.21 [1.00-1.46]), but lower risk for gestational diabetes (OR 0.58 [0.36-0.92]) and intrapartum hemorrhage during delivery (OR 0.81 [0.71-0.92]) compared to controls. No excess risk of adverse pregnancy outcomes in offspring was observed for FH. Among women with FH, statin exposure (mainly in the first trimester) may be associated with higher risk of low birth weight in offspring born at term (OR 2.42 [0.51, 11.45]).

Conclusions: Women with FH had lower risk of gestational diabetes and intrapartum hemorrhage, but a higher risk of preeclampsia compared to controls. No adverse birth outcomes were observed for offspring of mothers with FH, but the association between statin exposure in pregnant women with FH and low birth weight in offspring warrants further study.
