Armstrong AW, Mehta MD, Schupp CW, et al. - According to the findings of this cross-sectional study, psoriasis is still a common, immune-mediated disease that affects 3.0% of the adult population in the United States, or more than 7.5 million adults. Its prevalence has remained constant since 2003. These prevalence data are critical for calculating the psoriasis burden and supporting efforts in research, education, and health policy.

• In total, 12,625 people (mean [SD] age, 32.8 [24.1] years; 6,492 women [51.4%]; and 4,828 non-Hispanic White people [38.2%]) responded to the question of whether they were diagnosed with psoriasis by a physician or another healthcare professional.

• Psoriasis affected 3.0% of adults in the United States aged 20 and above.

• According to the 2020 US census data, this translates to an estimated 7.55 million US adults suffering from psoriasis.

• The prevalence of psoriasis was similar in men and women, with 3.2% in women and 2.8% in men.

• Psoriasis was most common in White people (3.6%), followed by other racial/ethnic groups (non-Hispanic, including multiracial) at 3.1%, Asian people at 2.5%, Hispanic people (including Mexican Americans and other Hispanic people) at 1.9%, and Black people at 1.5%.

• The prevalence of psoriasis did not differ based on patients' marital status, education, income, or medical insurance status.

• Since 2003, the prevalence of psoriasis among adults in the United States has not changed significantly.
