Abstract
OBJECTIVES
This study was carried out to estimate the magnitude of occupational asthma and to determine its characteristics.
METHODS
We collected and analyzed 121 cases of occupational asthma reported by a surveillance system in Incheon for 5 years. The cases were classified according to industry and causing gent. We attached the data to worker's compensation records to establish the degree of agreement between the two sources.
RESULTS
The industry of musical instrument manufacture was the most common (31 cases, 25.6%), followed by furniture manufacture, dye making, and machinery manufacture. TDI was the most common causing agents (52 cases, 43%), followed by reactive dye, wood dust, and organic dust. There was poor agreement with the worker's compensation records (2 cases, 8%).
CONCLUSIONS
TDI and reactive dyes were the major materials causing occupational asthma. Most cases reported by the surveillance system were not applied to the worker's compensation system. Therefore, the surveillance system should be used to estimate the magnitude of occupational asthma and to determine its characteristics.
