Data From 2019 GBD Highlights Burden of Psoriasis

A recent study found that psoriasis burden is greatest in patients aged 60 to 69 years, and that this burden is significantly greater in high-income and high sociodemographic index (SDI) countries within North America and Europe.

Data were extracted from the Global Burden of Disease (GBD) 2019 study, and prevalence data were combined with disability weight to yield years lived with disability (YLDs). Researchers also measured burden at global, regional, and national levels that were generated for incidence, prevalence, and YLDs. Additionally, they assessed psoriasis burden by SDI.

The study’s findings showed that, according to the GBD 2019 methodology, there were 4,622,594 incident cases of psoriasis worldwide with the age-standardized incidence rate being 57.8 per 100,000 people. Additionally, the age-standardized incidence rate was similar between men and women. There was a variance in age-standardized incidence rates per 100,000 persons across geographic locations. These findings revealed that, regionally, high-income countries and territories had the highest age-standardized incidence rate of psoriasis with high-middle SDI countries following second, and low SDI countries being the lowest. These trends were similar for prevalence and YLDs.

“With advances in psoriasis therapeutics, objective evaluation of psoriasis disease burden is critical to track the progress at the population level,” wrote the authors.
