- Psoriatic arthritis (PsA) prevalence is estimated at 0.1-0.2% globally with notable geographic variation.
- Around 20% of psoriasis patients develop PsA, influenced by age, severity, criteria, and region.
- Incidence rates range from 3 to 41 per 100,000 person-years, with increasing prevalence in some countries.
- Risk factors include severe psoriasis, nail involvement, obesity, and inflammatory arthralgia.
- Epidemiological data show heterogeneity due to methodological differences and diagnostic practices.
- Advanced systemic therapies for psoriasis may impact future PsA incidence, but more evidence is needed.
