Résumé
Very few studies evaluated the global prevalence of pruritus. To assess its prevalence according to age, gender, ethnicity, and geographic regions. An international cross-sectional study was conducted in 20 countries from January to April 2023. Participants were asked to complete a questionnaire on sociodemographics, confirm the presence or absence of a skin disease in the last 12 months and the presence or absence of pruritus in the last 7 days. The studied sample included 50552 individuals. The worldwide prevalence of pruritus was 39.8%. The age group ≥65 had the highest prevalence (43.3%). The prevalence was 40.7% among women and 38.9% among men (p<0.001). There was no significant difference between ethnicities (p=0.14). Compared to North America (41.6%), the prevalence of pruritus was significantly lower in Europe (35.9%, p<0.001), Australia (38.4%, p=0.017), East Asia (40.2%, p=0.04), and Latin America (36.5%, p<0.001), and higher in Africa (45,7%, p=0.007). No significant difference was found with the Middle East (40.2%, p=0.36). The prevalence was 40.3% in developed countries and 38.7% in BRICS countries 40.7% (p<10-3). No information about the severity or type (acute, chronic) of pruritus. Global prevalence of pruritus revealed age, gender, and geographic region differences, with no ethnic differences.
