[Effect of walking during all weekdays, holidays, and at work on mental and physical health in workers]

In order to clarify the effects of walking under various psychosocial and occupational conditions on psychophysiological health, we examined the relationship between the number of steps walked in several situations, such as on all weekdays, at work, and over the weekend, and the results of medical checkups, psychological tests, Breslow's 7 health practices, and other attitudes toward walking as well as health by using a pedometer in a certain manufacturing company. Most of the workers estimated their usual number of steps walked as being less than actual levels on both weekdays and holidays. Generally, the increased number of steps walked was significantly correlated with increased HDL-cholesterol levels, and decreased Triglyceride levels. Contrary to such physical effects, there were more variations with respect to the relationship between walking and psychological health. Moreover, the development of a walking habit at work resulted in some factors becoming worse, such as relaxation, trait anxiety, and serum AST levels when compared to those on all weekdays and over the weekend. In conclusion, it is necessary to consider several situations in which workers usually walk and we must also practice counseling and education for health promotion, to promote walking for health care in the workplace.
