Analysis of risk factors for contact dermatitis in pig farm workers / 中华劳动卫生职业病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the risk factors for contact dermatitis in pig farm workers.</p><p><b>METHODS</b>The cross-sectional questionnaire survey and on-site survey were conducted in pig farms raising more than 50 pigs in a county of Fujian Province, China. The study subjects were grouped based on different factors. The incidence rate was compared between groups by statistical analysis.</p><p><b>RESULTS</b>Of 302 subjects, 70 (23.18%) had contact dermatitis. There was a significant difference in the prevalence of contact dermatitis between the subjects in direct contact with commercially available pannage and those in indirect contact (χ(2) = 14.552, P < 0.01). Region, season, farm scale, brand of pannage, and allergic history were not influential factors for contact dermatitis (P > 0.05 for all).</p><p><b>CONCLUSION</b>Direct contact with commercially available pannage is closely associated with contact dermatitis in pig farm workers.</p>
