Association of maternal psoriasis and small for gestational age or preterm birth: a nationwide matched cohort study in 69 080 singleton infants.

Maternal psoriasis was not associated with increased risk of SGA or PTB. Risk of term SGA was slightly increased in women with a history of psoriasis compared with matched controls, however; these infants are likely to be constitutionally small with no increased risk of perinatal morbidity and mortality.
