P-210 Prevalence and incidence of hand eczema in hairdressers a systematic review and meta-analysis

Introduction

Hairdressers are at increased risk for hand eczema (HE) due to frequent skin contact with irritants and allergens in the workplace. Individuals with (a history of) atopic dermatitis are more susceptible to develop occupational HE. This study aims to review the current prevalence and incidence of HE in hairdressers, as well as the pattern of disease onset and severity. Furthermore, to assess the contribution of atopic dermatitis on HE in hairdressers.

Material and Methods

A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies published from 2000 to April 2021 that fulfilled predefined eligibility criteria were retrieved.

Results

Nine studies (n = 10 952 participants) reported on the life-time prevalence, yielding an estimate of 38.2% (95% CI 32.6–43.8). A pooled 1-year prevalence of HE amounted to 20.3% (95% CI 18.0–22.6), and a pooled point prevalence to 7.7% (95% CI 5.8–9.6). A pooled lifetime prevalence of 37.5% and 37.0% was obtained for hairdressing apprentices and fully trained hairdressers, respectively. The pooled incidence rate of HE was 51.8 cases/1000 person-years (95% CI 42.6–61.0). The prevalence of AD in hairdressers was comparable with estimates in the general population.

Conclusions

This systematic review reveals that hand eczema is common in hairdressers and starts early in the carrier, often during apprenticeship. The prevalence of atopic dermatitis in hairdressers is comparable with estimates in the general population, pointing to the occupational exposures as the main risk factor for HE in hairdressers. This emphasizes the need for targeted and collective prevention strategies in hairdressing sector, starting already during apprenticeship.
