Abstract
In all, 896 Finnish farmers (305 men and 587 women), representing 77% of those reporting hand or forearm dermatosis in a questionnaire survey in 1979, were asked again about their dermatosis and current work in 1991. More than 50% of the study population had left farming since 1979. In 1991, 26% of men and 21% of women had a current dermatosis on the hands or forearms, and altogether, 44% of men and 39% of women reported a hand dermatosis within the past 12 months. Significant determinants of persistent hand dermatosis, in a logistic regression model, were continuation of farm work, history of skin atopy, symptoms of metal allergy, and age under 45 years. Handling cattle, e.g., milking, was considered an exacerbating factor of the dermatosis by 37% of those who had milked sometimes in their lives. In this group, 75% of hand dermatoses in those who had finished milking work had healed. The results indicate that giving up or changing work improves the prognosis of hand dermatosis in farming.
