title: Psychosocial job characteristics and smoking cessation: a prospective cohort study using the Demand-Control-Support and Effort-Reward Imbalance job stress models.
abstract: BACKGROUND
  A prospective cohort study was conducted to examine the effects of psychosocial job characteristics on smoking cessation. Previous studies have failed to indicate consistently that psychosocial job characteristics predicted smoking cessation. Using the Demand-Control-Support (DCS) and Effort-Reward Imbalance (ERI) models simultaneously, we assessed psychosocial job characteristics more comprehensively than did previous researchers.
  
  
  METHODS
  This study was performed using a population derived from a corporate manufacturing group in Japan. At the baseline, 579 (41%) of 1,423 middle-aged (> or = 39 years) male employees were smokers. These male smokers were considered as the study subjects and were asked to undergo a follow-up examination after 2 years. Prospective analysis of the relationship between psychosocial job characteristics at the baseline and smoking cessation at the follow-up was performed. Job strain, social support, effort-reward imbalance, and overcommitment to work were assessed as psychosocial job characteristic factors.
  
  
  RESULTS
  The smoking cessation rate among the study subjects at the follow-up was recorded as 5% (31/579). No psychosocial job characteristic factors at the baseline were significantly related to smoking cessation at the follow-up.
  
  
  CONCLUSIONS
  Even with the simultaneous use of the DCS and ERI models, we did not find positive results in terms of the prospective effects of psychosocial job characteristics on smoking cessation. Considering the results of relevant previous studies and those of the present study, we suppose that psychosocial job characteristics could have essentially little effect on smoking cessation.
