Abstract:
OBJECTIVES: The incidence rate of pneumoconiosis among retired coal miners was studied at Taebackchungang hospital. METHODS: Newly developed pneumoconiosis0=1/0) cases were gathered from films of ex-coal miners who were diagnosed as normal at the previous examination after retirement. RESULTS: 228 exminers were confirmed as normal at the previous examination after retirement. 37 ex-miners were diagnosed as pneumoconiosis (equal or greater than 1/0) at the next examination. CONCLUSIONS: The incidence rate was 29.5/1000 person-year. The incidence was calculated by the examined year. In 1995, 1996, 1997, the incidence rates were 104. 8, 37. 1, 14.1 per 1000 person-year respectively. There was no development of pneumoconiosis among retired coal miners who retired more than 20 years ago or who worked less than 10 years.
