Abstract

Objectives: We wanted to investigate the relationship of shift work to the cardiovascular and gastrointestinal symptoms of Korean female workers. Methods: The data was analyzed from a cross-sectional survey of 1,875 Korean female workers. Information was obtained about the shift work, the cardiovascular and gastrointestinal symptoms and the background characteristics. Multiple regression analysis was used to test for the relationship between the cardiovascular and gastrointestinal symptoms and the shift work variables, while controlling for the covariates. Results: Shift work was more common for blue-collar workers than for office workers. A higher proportion of current smokers and drinkers was observed for shift workers than for day workers. A full-time job was more popular for shift workers than for day workers, while more day workers worked over 8 hours per day than did the shift workers. The mean scores of the cardiovascular and gastrointestinal symptoms were significantly higher for shift workers than for day workers. Shift work was associated with 0.54 more cardiovascular symptoms and with 0.38 more gastrointestinal symptoms on a multiple regression analysis (p=0.001; p=0.020, respectively). Conclusions: Our findings suggest that shift work may increase the risks for cardiovascular and gastrointestinal disturbances. Therefore, preventive strategies are needed to control the negative effects of shift work in the workplace.
