Abstract:
OBJECTIVE:To explore the effect of dust exposure, type of work, age, length of service and duration of dust exposure on pulmonary function in coal miners by pulmonary function tests.
METHODS:A total of 1 953 coal miners, who received occupational healthy examination and pulmonary function tests during June, 2013 and August, 2014 in Hunan Prevention and Treatment Institute, were enrolled for this study.
RESULTS:A total of 1 302 miners (66.7%) displayed pulmonary dysfunction, including 1 139 with mild dysfunction (58.3%) and 163 with moderate or more serious dysfunction (8.3%). The risk factors for pulmonary dysfunction were age (OR=1.329, 95% CI: 1.196-1.620), dust exposure duration (OR=1.267, 95% CI: 1.136-1.413) and type of works (mining workers OR=1.156, 95% CI: 1.033-1.293; all P<0.05).
CONCLUSION:The incidence rate of pulmonary dysfunction in coal miners is relatively high in Hunan Province. Most of them are mild dysfunction. The incidence rate of pulmonary dysfunction in mining works is statistically higher than that in other work types. Older workers and long duration-exposed workers are more likely to have pulmonary dysfunction.
