1. Active psoriatic arthritis during pregnancy was associated with higher rates of pre-eclampsia (8.8% versus 2.6%) and gestational hypertension (5.9% versus 1.7%) compared with population controls.
2. Women with inactive psoriatic arthritis (PsA) had hypertensive disorder rates comparable to controls, highlighting disease activity—not diagnosis alone—as the key risk driver.
3. No increase in preterm birth or fetal growth abnormalities was observed across PsA activity groups.
4. Obesity amplified hypertensive risk in women with active PsA, though subgroup differences did not reach statistical significance.
5. Optimizing PsA control before and during pregnancy may improve maternal outcomes, reinforcing coordinated care between rheumatology and obstetrics.
