    Although it isn’t easy to predict whether patients with psoriasis will develop psoriatic arthritis, some potential risk factors have been identified, including:[1]

    • Corticosteroid use within 2 years of first developing psoriasis
    • Pregnancy within 2 years prior to psoriasis onset[2]
    • Trauma that required medical care[3]
    • Vaccination against rubella[3]
    • Smoking
    • Infections requiring hospitalization
    • Heavy drinking
    • Family history of psoriatic arthritis
    • Obesity

    It is important to note that the above risk-associations were mostly found through case-control (observational) studies, so it isn’t yet clear whether they play a causative role in developing the disease.
