Abstract

To investigate the relationship between physical health of workers and industrial accidents, a case-control study was carried out using matched samples of 87 injured steel industry workers and 87 non-injured steel industry workers. One group of people who experienced industrial accidents more than two times were case, and the other group of people who matched the type of work and duration of employment were control. We surveyed questionnaire between July 20, 1988 and July 22, 1988. The results were as follows: 1. The average age of injured workers was 39 years, and non-injured workers was 38 years. Duration of employment of injured workers was 8.4 years and non-injured workers was 8 years. 2. Visual acuity under 1.0 were 24.4 percent in injured workers and 19.5 percent in non-injured workers. Hearing threshold over 40 dB were 77.1 percent in injured workers and 60.9 percent in non-injured workers. 3. As for the Fugamachi classification method, 22.9 percent of injured workers and 20.8 percent of non-injured workers were group III(suspected neurotics). 4. As for the item of CMI(Cornell Medical Index), injured workers were higher rates than non-injured workers in the item of C(cardiovascular system), M(inadequency), O(anxiety), P(sensitivity), Q(anger), and R(tension). 5. Especially, injured workers who had more than three times were higher in the item of C(cardiovascular system), M(inadequency), N(depression), P(sensitivity), Q(anger), R(tension) than non-injured workers.
