title: Prevalence of Obesity in Patients with Psoriasis: Results of the National Study PsoHealth3.
abstract: BACKGROUND
  Psoriasis is frequently associated with obesity which possibly contributes to reduced treatment response.
  
  
  OBJECTIVE
  Assessment of the prevalence of obesity in patients with psoriasis in Germany 2013/2014.
  
  
  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.
