Background: Chronic skin diseases such as psoriasis (PSO), atopic dermatitis (AD) and hidradenitis suppurativa (HS) are frequently associated with psychological distress, potentially promoting maladaptive coping mechanisms including addictive behaviours. Despite evidence of higher addiction rates among dermatology patients, comprehensive multicenter data across Europe are lacking. Objectives: To estimate the prevalence and patterns of addictive behaviours among patients with chronic skin diseases in European tertiary dermatology centres and explore associated sociodemographic and clinical factors. Methods: This multicentre cross-sectional study recruited adult patients with PSO, AD, HS, alopecia areata (AA), urticaria, or vitiligo from dermatology departments in 20 European countries. Participants completed a standardized questionnaire assessing sociodemographics, disease characteristics, and addictive behaviours (smoking, alcohol use, drug use, gambling, internet addiction, and eating disorders). Descriptive analyses and multivariate logistic regression were performed. Results: Among 3585 participants (median age 43 years; 51.1% female), the prevalence of addictive behaviours was notable: smoking (25.7%), pathological gambling (4.5%), hazardous drinking (8.8%), alcohol dependence (2.5%), drug use disorders (5.3%), eating disorders (1.8%), and internet addiction (29.7%). Smoking was most common among PSO and HS patients (48.6%), and gambling among AA and vitiligo patients (8.2%). Significant associations included male sex, younger age, single status, higher Dermatology Life Quality Index (DLQI) scores, and regional variation. Discussion: Addictive behaviours are prevalent in dermatology patients and are associated with both sociodemographic and disease-related factors. The DLQI was positively correlated with multiple addictions, suggesting that reduced quality of life may contribute to maladaptive coping. However, due to the absence of a control group, the tertiary care setting, limited center distribution, and unknown response rate, generalizability is restricted. Conclusion: Addiction screening and supportive mental health strategies should be integrated into dermatologic care, particularly for high-risk patients. Population-based studies with control groups are needed to confirm these findings.

Abstract
Background: Chronic skin diseases such as psoriasis (PSO), atopic dermatitis (AD) and hidradenitis suppurativa (HS) are frequently associated with psychological distress, potentially promoting maladaptive coping mechanisms including addictive behaviours. Despite evidence of higher addiction rates among dermatology patients, comprehensive multicenter data across Europe are lacking. Objectives: To estimate the prevalence and patterns of addictive behaviours among patients with chronic skin diseases in European tertiary dermatology centres and explore associated sociodemographic and clinical factors. Methods: This multicentre cross-sectional study recruited adult patients with PSO, AD, HS, alopecia areata (AA), urticaria, or vitiligo from dermatology departments in 20 European countries. Participants completed a standardized questionnaire assessing sociodemographics, disease characteristics, and addictive behaviours (smoking, alcohol use, drug use, gambling, internet addiction, and eating disorders). Descriptive analyses and multivariate logistic regression were performed. Results: Among 3585 participants (median age 43 years; 51.1% female), the prevalence of addictive behaviours was notable: smoking (25.7%), pathological gambling (4.5%), hazardous drinking (8.8%), alcohol dependence (2.5%), drug use disorders (5.3%), eating disorders (1.8%), and internet addiction (29.7%). Smoking was most common among PSO and HS patients (48.6%), and gambling among AA and vitiligo patients (8.2%). Significant associations included male sex, younger age, single status, higher Dermatology Life Quality Index (DLQI) scores, and regional variation. Discussion: Addictive behaviours are prevalent in dermatology patients and are associated with both sociodemographic and disease-related factors. The DLQI was positively correlated with multiple addictions, suggesting that reduced quality of life may contribute to maladaptive coping.
