title: [Analysis of risk factors for contact dermatitis in pig farm workers].
abstract: OBJECTIVE
  To investigate the risk factors for contact dermatitis in pig farm workers.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Direct contact with commercially available pannage is closely associated with contact dermatitis in pig farm workers.
