Effect of lifestyle modification program implemented in the community on workers' job satisfaction.

It is important for occupational health to justify the impact of health promotion programs on job satisfaction, which is associated with work-related outcomes. The aim of this study is to estimate the effects of lifestyle modification activity implemented by the community on job satisfaction, and to analyze the factors which contributed to the improvement of workers' job satisfaction. A lifestyle modification program consisting of aerobic exercise and diet counseling was conducted for 12 wk in the community. Data on 264 workers were obtained before and after the intervention. The subjects were asked to fill out questionnaires about work-related items, lifestyle, and mental health status. In addition to the ameliorations of GHQ, lifestyle, subjective complaints, and the risk factors of lifestyle-related diseases, an improvement in workers' job satisfaction was shown by the participation in the community-based lifestyle modification program. For analyzing factors which contributed to the improvement in job satisfaction, logistic regression analysis was employed. Refreshment from fatigue by sleep independently contributed to the improvement of job satisfaction even after adjusting for the other variables. The health promotion program implemented in the community may be useful for workers' job satisfaction especially through the dissipation of fatigue by refreshment sleep.
