Abstract

Objectives

This study was performed to analyze the factors that have been meaningful in recognizing cerebrovascular and cardiovascular diseases in manufacturing sector workers as work-related diseases, since amendment of Industrial Accident Compensation Insurance Act on July 1st, 2008, and provide information to establish an objective standard.

Methods

We examined 359 claims of cerebrovascular and cardiovascular diseases which were presented as occupational diseases from January 1st, to December 31th, 2010, collecting Industrial Accident Compensation data from the six Provincial Committees for work-related disease decision. We analyzed the approval rate and odds ratio of the general characteristics, past medical history and work-related information, by using univariate logistic regression. In addition, we confirmed the factors that have effects on when approving work-related diseases by using multivariate logistic regression.

Results

Overall, 92 claims out of the 359 claims were recognized as worked-related diseases with an approval rate of 25.6%. Because of accidental situations such as altercation, cold environments, fire etc., only 12 cases were approved. In addition, due to short-term overwork such as outdoor work in cold environments, only 18 cases were approved. Sixty-two cases were approved for chronic overwork. On chronic overwork, the approval rate was not significantly different in univariate logistic regression in gender, age, claimed disease, survival or death, smoker or non-smoker, or associated disease. However, factory size and, average working time for last one week and average working time for last four weeks were significantly. In the multivariate logistic regression analyzed, adjusted for age and sex, we found that the factors in approving cerebrovascular and cardiovascular disease as work-related disease were average working time for the last four weeks and factory size.

Conclusion

We concluded that there has been a great deal of subjective judgements when approving cerebrovascular and cardiovascular diseases to be occupational diseases. Therefore, objective criteria should be established, especially with regard to the approval of work-related cerebrovascular and cardiovascular diseases and working hours.
