The contribution of metal allergies is poorly elucidated even though such exposures are common at the workplace. To estimate the prevalence of metal allergy to cobalt (Co), chromium (Cr) and nickel (Ni) in metalworkers and compare these to estimates from the European Surveillance System on Contact Allergies (ESSCA). Two authors independently searched PubMed for studies reporting on the prevalence of metal allergy in metalworkers. Proportion meta\u2010analyses were performed to calculate the pooled proportions of metal allergy in metalworkers. In total, 29 studies (22 from Europe) were included yielding 5691 subjects for quantitative analysis. The pooled proportion (95% confidence interval) of Co, Cr and Ni in European metalworkers with dermatitis referred to patch test clinics was 8.2% (5.3%\u201311.7%), 8.0% (5.1%\u201311.4%), and 11.0% (7.3%\u201315.4%), respectively. The corresponding estimates for unselected metalworkers from workplace studies were 4.9% (2.4%\u20138.1%), 5.2% (1.0%\u201312.6%), and 7.6% (3.8%\u201312.6%), respectively. In comparison, the prevalence of metal allergy in 13\u2009382 consecutive European males with dermatitis was 3.9% (3.6%\u20134.2%), 4.4% (4.1%\u20134.8%) and 6.7% (6.3%\u20137.0%) for Co, Cr and Ni, respectively. Data on sex, age, body piercings and atopic dermatitis in metalworkers with metal allergy was mostly lacking. Metal allergy to all three metals was significantly more common in European metalworkers with dermatitis attending patch test clinics as compared to ESSCA data, indicating a relationship to occupational exposures, however, confounders could not be accounted for.<\/jats:p>","DOI":"10.1111\/cod.14232","type":"journal-article","created":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T11:49:29Z","timestamp":1665229769000},"page":"1-9","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Contact
