Impact of Work Environments and Occupational Hazards on Smoking Intensity in Korean Workers

The purpose of this study was to investigate the influence of work environments and occupational hazards on smoking intensity by occupation type in Korean workers. This study used the data from the Fourth Korea National Health and Nutrition Examination Survey in 2009. The sample of this study included 3,769 adults who were aged 18 years or older and had an occupation of office work, sales, or manufacturing. After controlling for sociodemographic characteristics, the generalized linear models revealed that office workers and the sales force who had smoking co-workers at the workplace were more likely to smoke than those who did not. A dirty workplace and exposure to occupational noise were significant factors increasing the smoking intensity for manufacturers. A smoking cessation program considering physical work environments and co-workers' support should be developed for Korean workers.
