title: [Effects of biomass combustion and occupational exposures on lung function in random population sample of Malopolska inhabitants].
abstract: BACKGROUND
  Risk factors other than tobacco smoking contribute to about 20% of chronic obstructive pulmonary disease cases. Exposure to these risk factors and their influence on lung function has not been adequately studied in the population of Malopolska.
  
  
  METHODS
  In random population sample of adults at least forty years old, residents of 2 districts of Malopolska, data on exposure to known and probable respiratory risk factors were collected using questionnaire. All subjects without contraindications performed pre- and post-bronchodilatator spirometry.
  
  
  RESULTS
  We analyzed data from 618 subjects; 94,8% subjects lived for longer than 6 months in a dwelling where stove using coal or wood has been used for cooking and/or heating. At the time of study as many as 32.5% subjects were still using coal or wood for cooking or heating. Coal or wood were used as fuel on average for more than 30 years; 67% of subjects have ever worked in professions carrying a risk of exposure to potential respiratory risk factors. We have identified an independent relationship of farming with lower FEV1/FVC values as well as increased chronic obstructive pulmonary disease risk.
  
  
  CONCLUSIONS
  Significant proportion of Malopolska inhabitants has been exposed to risks associated with cooking or heating with coal or wood. In the studied population farming was related to increased risk of chronic obstructive respiratory disease.
