Title Persistence of respiratory symptoms in ex-underground iron ore miners
Bibliographic information 2006, No.56, p.380-385. 34 ref.
Abstract The objective of this case-control study was to assess the persistence of respiratory symptoms in ex-miners after cessation of mining exposure. Data were collected by means of a questionnaire comparing the prevalence of symptoms between ex-miners who had stopped mining at least one year before the study and referents not occupationally exposed to irritants or dust. Age, smoking and a family history of asthma were considered as possible confounders in the analysis. A total of 206 ex-miners and 4560 referents participated. 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 that other respiratory symptoms were more common in ex-miners.
