title: Skin photoaging in farmers occupationally exposed to ultraviolet radiation.
abstract: BACKGROUND
  Most personal exposures to UV radiations occur from outdoor activities and several studies detected a significant association between skin cancer and outdoor occupation.
  
  
  OBJECTIVE
  The aim of the study was to ascertain the prevalence of photoaging signs in a population of Italian farmers and in a population of indoor workers taking account of confounding factors.
  
  
  METHODS
  169 farmers and 198 indoor workers were classified for skin phototype and for skin photoaging, moreover 13 variables were taken into account. Marginal permutation tests were adopted for statistical analysis.
  
  
  RESULTS
  Farmers were significantly older than the indoor workers. In workers occupationally exposed to UV photoaging increased with increasing age and years of occupational exposure to sunlight The distribution of skin phototype did not show significant differences in the two populations, while farmer showed a higher degree of photoaging than indoor workers.
  
  
  CONCLUSIONS
  Even if farmers were older than the in door workers it seems that outdoor work produces a higher degree of photoaging.
