2. Statistics

The National Psoriasis Foundation has estimated that psoriatic arthritis affects about 30% of individuals with psoriasis, around 1 million individuals in the United States. However, various studies have reported varying prevalence rates. In a population-based study, there were less than 10% of individuals who had clinically recognized psoriatic arthritis throughout a 30-year duration.

A survey reported a 0.25% prevalence rate of psoriatic arthritis in the general population and 11% prevalence rate in patients with psoriasis. Globally, it is estimated that the average prevalence of psoriatic arthritis is 133 per 100,000 individuals. Among patients with psoriasis, about 1 in 4 patients have psoriatic arthritis. Psoriatic arthritis has been reported to be more common in Caucasians with equal ratio for both genders.
