Abstract

Background: Psoriasis is a chronic skin disease with a high mental burden. Well-known comorbidities include depression, anxiety, as well as alcohol and tobacco addiction, however, there is barely any evidence on other addictions. Objectives: The aim of this study was to estimate the prevalence of the six most common addictions among psoriasis patients in Germany and to determine associated clinical factors. Materials & Methods: Dermatologists working in four dermatological clinics and 32 practices across Germany recruited patients between September 2018 and November 2019. This cross-sectional study contained questionnaires on six addictions, depression, anxiety, and the Dermatology Life Quality Index (DLQI). In addition, scores for the Psoriasis Area and Severity Index (PASI) were obtained by physicians. Results: Overall, 502 patients (43.4% women; mean age: 49.7 ± 14.6 years) were included. Positive addictions were found in 30.3% for daily smoking, 8.6% for alcohol, 1.2% for gambling, 3.8% for internet use, 3.6% for food, and 6.0% for drugs. Younger age was associated with a higher probability of addiction except for alcohol dependency. The PASI was only significantly associated with smoking. Conclusion: Addictions seem to be common among psoriasis patients. Further research should include comprehensive data and control groups, furthermore, standardised screenings and early referrals could represent first steps to improve people-centred healthcare for patients with psoriasis.
