The prevalence of psoriasis is 3.0% among the US population aged 20 or older, according to a study published in JAMA Dermatology. Research- ers conducted a population-based cross-sectional study involving 2011-2014 National Health and Nutrition Examination Survey data to examine the prevalence of psoriasis among adults in the United States. Among 12,625 respondents, the prevalence of psoriasis translated to an estimated 7.55 million US adults with psoriasis based on the 2020 census data. The prevalence of psoriasis was similar for women and men (3.2% and 2.8%, re- spectively). Prevalence was highest among White individuals (3.6%), followed by other racial/ ethnic groups (non-Hispanic), Asian individuals, Hispanic individuals, and Black individuals (3.1%, 2.5%, 1.9%, and 1.5%, respectively). There was no difference in prevalence based on marital status, education, income, or medical in- surance status. No significant difference was seen in the prevalence of psoriasis since 2003. “These prevalence data are foundational to determining the burden of psoriasis and raising awareness of associated comorbidities,” the authors wrote. “In addition, these data may help inform future epi- demiologic research, clinician and patient educa- tion, and health policies to improve the lives of patients with psoriasis.”
