Abstract

This study aims to assess the annual changes in lung function among farm and nonfarm adult residences in rural Saskatchewan, Canada. Data from the Saskatchewan Rural Health Study survey (2010 to 2014) among 724 adults were used. For forced expiratory volume in 1 second (FEV1) measurements, estimates of annual decline (in milliliters) were highest in older age male (65+ years) (Mean, SD) (-42.63, 21.16); and among old heavy smokers (-57.79, 24.30). Estimates of annual decline in forced vital capacity (FVC) were highest in current smokers without the use of natural gas (-25.78, 14.78) and among old heavy smokers (-33.88, 20.28). Living on a farm is associated with decreased FEV1 and FVC, but not statistically significant by sex and age. A complex mix of personal and contextual factors may affect these estimates.
