This study was performed to investigate health-related behaviors and dietary attitudes among workers, using questionnaires with 338 workers in October 2005 who were employed by 5 industrial companies at the Gumi industrial complex.

An increase in their interest was observed with advancing age (p<0.05) and the level of interest was higher in females than males(p<0.05). Regarding a understanding of their health status, 57.4% of the total subjects considered their health status to be poor although there was no any known disease, while only 29.6% considered to be good. The subjects' dietary attitudes showed that the average of the each items was 2.88±0.82, and the average of the total items was 58.7±0.00. The average of their diet satisfaction was shown to be 2.88±0.82, and There was a significant difference in their diet satisfaction between residential building types(p<0.01) and work types(p<0.01). 66.8% of the total subjects answered that the main purpose of their meals was to fill an empty stomach. Their health-related behaviors, dietary attitudes and diet satisfaction showed that daily exercise, suitable diet and intake of health supplements were closely correlated with their dietary attitudes.
