Title Persistence of respiratory symptoms in ex-underground iron ore miners
Bibliographic information Sep. 2006, Vol.56, No.6, p.380-385. 34 ref.
Abstract To assess the persistence of respiratory symptoms in ex-miners after cessation of mining exposure, this population-based cross-sectional study used a postal questionnaire comparing prevalence of symptoms between 206 ex-miners who had stopped mining at least one year before the study and 4560 referents not occupationally exposed to irritants or dust. Age, smoking and a family history of asthma were considered as possible confounders in the analysis. Ex-miners had on average been working as miners for 13 years and had stopped mining 16 years before the study. Chronic productive cough and physician-diagnosed chronic bronchitis were significantly more common among ex-miners. Furthermore, there was a trend of other respiratory symptoms being more common in ex-miners.
