The Effect of Shift Work on Life Style and Blood Pressure in Male Shift Workers / 항공우주의학회지

ABSTRACT

BACKGROUND: The aim of this cross-sectional study was to evaluate the effects of shift work on life style and blood pressure in male shift workers. METHODS: The study population included 617 male workers, with 2 year work experience. The participants were divided into two groups (259 shift workers/358 non-shift workers) according to shift work. The differences in life style, cardiovascular risk factors such as blood pressure and job strain were compared among the two groups. RESULTS: The shift work group was associated with increased age, higher smoking rate, more regular exercise and less job demand (P<0.05). In comparison of blood pressure by general characteristics and job stress, systolic blood pressure was significantly increased in drinking and obese workers and diastolic blood pressure significantly increased in obesity and low decision latitude. The association between shift work and blood pressure by age groups was confirmed by multivariate general linear model analysis including age, smoking, drinking, exercise, obesity and job stress. CONCLUSION: The results showed that exercise, smoking, and job stress were significantly different in the shift worker group compared to non-shift worker group.
