Topical corticosteroids in pregnancy 'have no impact on birth weight'

The large Danish cohort study should allay concerns, researchers say

Use of topical corticosteroids does not appear to increase the risk of newborns being small for gestational age (SGA) or having low birth weight, according to a large cohort study.

Researchers examined Danish medical birth registry data covering more than 11 million pregnancies between 1997 and 2016.

The team identified more than 60,000 corticosteroid-exposed pregnancies and matched them with 260,000 pregnancies without such exposure.

The proportion of infants that were SGA was 9.4% — the same in both groups, the team reported in JAMA Dermatology.
