Kim HN, et al. - Researchers conducted this nationwide population-based study to examine the connection between the presence of metabolic syndrome (MetS) and its components and the risk of psoriasis development. Utilizing data from the Korean National Health Insurance Service (2009 to 2017), 9,718,591 adults (2,595,878 in the MetS group and 7,122,713 in the comparison group) were assessed. After adjusting for age, sex, smoking status, alcohol consumption, physical activity, household income, and body mass index, MetS was positively linked to an increased risk of psoriasis over an 8-year follow-up period. As the number of MetS components increased, the risk of psoriasis tended to rise’ this trend was significant in obese subjects. Overall, the authors concluded that MetS is a risk factor for psoriasis development.
