Ship's engineers are exposed to mineral oil and solvents in their work
. This study was intended to investigate if ship's engineers had an in
creased prevalence of skin disorders and whether any such increased ri
sk could be linked to exposure to mineral oils and solvents. A self-ad
ministered questionnaire was sent to 700 male seamen from 3 Norwegian
ferry companies. Of the 492 respondents, 169 were currently working as
ship's engineers and 295 had never worked as ship's engineers. The ou
tcomes eczema. acne, dry skin, any dermatitis and hand dermatitis were
defined from the questionnaire. Prevalences of these skin disorders w
ere compared between the groups. Logistic regression was used to eluci
date explanatory variables further. When comparing current ship's engi
neers with those who had never worked as ship's engineers, the crude p
revalence ratios were 1.7 (95% CI 1.1-2.7) for dry skin, 1.7 (95%CI 1.
1-2.5) for any dermatitis, 1.3 (95%CI 0.66-2.67) for acne and 1.2 (CI
0.61-2.27) for eczema. The risk of these symptoms increased for the en
gineers in the regression analysis, after controlling for age, self-re
ported use of Stoddard solvent, and the use of fuel oil as a hand clea
nsing agent. The increased prevalence of skin disorders found among sh
ip's engineers in this investigation may be explained by direct contac
t with mineral oils and solvents.
