Abstract
BACKGROUND: There are few population-based studies assessing the prevalence of skin diseases. OBJECTIVES: To estimate the prevalence of five chronic skin inflammatory diseases, i.e. atopic dermatitis (AD), psoriasis, alopecia areata (AA), vitiligo and hidradenitis suppurativa (HS) in France, using validated self-diagnostic questionnaires. METHODS: Population-based study using a representative sample of the French general population aged more than 15 years and sampling with replacement design. All participants were asked (ii) to fill in a specific questionnaire including socio-demographic characteristics, (ii) to declare if they have been diagnosed with one or more skin problem or skin diseases during their life, and (iii) to fill in five validated self-reported questionnaires for AD, psoriasis, AA, vitiligo and HS. RESULTS: A total of 20.012 adult participants responded to the questionnaire of whom 9760 were men (48.8%) and 10.252 (51.2%) were women. We identified a prevalence of 4.65% for AD (931 individuals), 4.42% for psoriasis (885 individuals), 1.04% for AA (210 individuals), 0.46% for vitiligo (93 individuals) and 0.15% for HS (29 individuals), respectively. LIMITATIONS: Questionnaire-based study and possible disease misclassifications. CONCLUSION: This is the largest population-based study aiming to estimate the prevalence of five chronic skin inflammatory diseases.
