Prevalence of Obesity in Patients with Psoriasis: Results of the National Study PsoHealth3

BACKGROUND: Psoriasis is frequently associated with obesity which possibly contributes to reduced treatment response.

OBJECTIVES: Assessment of the prevalence of obesity in patients with psoriasis in Germany 2013/2014.

PATIENTS AND METHODS: The frequency of overweight and obesity was assessed by the body mass index (BMI) and evaluated according to the severity of psoriasis [Psoriasis Area and Severity Index (PASI)].

RESULTS: This national, cross-sectional survey involved 83 dermatological practices and outpatient clinics, including 1,265 patients (mean age 52 years; 43.4% female). The BMI of patients with psoriasis in 2013/2014 was found to be 28.0 and therefore was significantly higher compared to that of patients with psoriasis in 2007 with a BMI of 26.9 as well as compared to the normal population in 2013 with an overall BMI of 25.9.

CONCLUSIONS: The prevalence of obesity in patients with psoriasis is higher than in the normal population. The trend towards a higher BMI in patients with psoriasis continues over time.
