BACKGROUND: Mechanics are at higher risk to develop occupational skin diseases from exposure to irritants, oils, greases, preservatives, and metals. AIMS: The aim of the study was to investigate contact dermatitis in mechanics who underwent patch test in Northeastern Italy and compare them with white-collar workers (WCW). SUBJECTS AND METHODS: From 1996 to 2016, 27,381 patients with suspected allergic contact dermatitis were patch tested in Northeastern Italy; in this group, 1270 mechanics were studied. Odds ratios (ORs) and 95% confidence interval (CI), adjusted by age and sex, were calculated assuming WCW as the reference category (n = 6933). RESULTS: Mechanics represented 4.6% of the population tested. Their mean ± SD age was 36.1 ± 11.2 years. Compared with WCW, they were found to have an increased risk of occupational dermatitis (OR = 14.4; 95% CI = 11.6-18) and hand/forearm dermatitis (OR = 2.5; 95% CI = 2.3-2.9). They presented an increased risk of sensitization to epoxy resin (OR = 2.7; 95% CI = 1.5-4.8), to thiurams (OR = 2.4; 95% CI = 1.5-3.8), to 2-mercaptobenzothiazole (OR = 1.9; 95% CI = 1.1-3.4), and to diaminodiphenylmethane (OR = 1.7; 95% CI = 1.1-2.5). CONCLUSIONS: Compared to WCW, mechanics were found to be at higher risk to develop occupational contact dermatitis, associated mainly to sensitization to epoxy resin and rubber accelerators.

Abstract

BACKGROUND: Mechanics are at higher risk to develop occupational skin diseases from exposure to irritants, oils, greases, preservatives, and metals. AIMS: The aim of the study was to investigate contact dermatitis in mechanics who underwent patch test in Northeastern Italy and compare them with white-collar workers (WCW). SUBJECTS AND METHODS: From 1996 to 2016, 27,381 patients with suspected allergic contact dermatitis were patch tested in Northeastern Italy; in this group, 1270 mechanics were studied. Odds ratios (ORs) and 95% confidence interval (CI), adjusted by age and sex, were calculated assuming WCW as the reference category (n = 6933). RESULTS: Mechanics represented 4.6% of the population tested. Their mean ± SD age was 36.1 ± 11.2 years. Compared with WCW, they were found to have an increased risk of occupational dermatitis (OR = 14.4; 95% CI = 11.6-18) and hand/forearm dermatitis (OR = 2.5; 95% CI = 2.3-2.9). They presented an increased risk of sensitization to epoxy resin (OR = 2.7; 95% CI = 1.5-4.8), to thiurams (OR = 2.4; 95% CI = 1.5-3.8), to 2-mercaptobenzothiazole (OR = 1.9; 95% CI = 1.1-3.4), and to diaminodiphenylmethane (OR = 1.7; 95% CI = 1.1-2.5). CONCLUSIONS: Compared to WCW, mechanics were found to be at higher risk to develop occupational contact dermatitis, associated mainly to sensitization to epoxy resin and rubber accelerators.
