Through this meta-analysis, we aim to provide an overview and statistical synthesis of the prevalence of MetS and its components in psoriatic arthritis (PsA) compared to the general populations, patients with cutaneous psoriasis (PsO), and patients with other inflammatory arthropathies. A search was conducted in Ovid Medline, Web of Science, and Scopus up to February 2024. Original articles investigating the prevalence of MetS in PsA in adults compared to one or more comparison populations were included. Bias risk was assessed by means of a funnel plot. The data was analyzed by means of a random effects model and presented in forest plots. Of 1526 articles in the original search, 20 relevant were identified. Meta-analyses showed an increased prevalence of MetS in PsA compared to the general population, rheumatoid arthritis (RA), and ankylosing spondylitis (AS) (LogOR 0.93, 0.63, and 1.04, respectively). Meta-analysis showed no difference in the prevalence of MetS in PsA compared to PsO (LogOR 0.15, I2 0.63). Meta-analysis of the prevalence of the different components of MetS in PsA compared to RA showed an increased prevalence of central obesity, hypertriglyceridemia, impaired glucose tolerance, and diabetes mellitus. PsA was associated with an increased risk of MetS compared to the risk in the general population, in RA and in AS, respectively. This emphasizes the importance of screening for and taking necessary measures to prevent MetS in patients with PsA. Key Points • Patients with PsA have an increased risk of MetS compared to the general population as well as patients with RA or AS. • According to this meta-analysis, the risk of MetS is the same in patients with PsA as in patients with PsO.
