title: Fatigue, emotional exhaustion and perceived health complaints associated with work-related characteristics in employees with and without chronic diseases.
abstract: OBJECTIVE
  Ageing of the Dutch working force and increasingly more stringent restrictions regarding early retirement and disability benefits are leading to higher numbers of workers with ill health. Until now, only a few studies have explored how employees with ill health perceive their work. This study investigated possible differences in scores on fatigue, emotional exhaustion, perceived health complaints and various work-related characteristics between chronically ill (CIWs) and non-chronically ill workers (NCIWs), as well as differences in associations between work- and health-related characteristics.
  
  
  METHODS
  A questionnaire was sent to all employees of a Dutch university to collect data on perceived work-related and health-related characteristics (response 49.1%). Differences in various scores were analysed using chi (2)-tests and the general linear model. Associations between the work- and the health-related characteristics were determined by multiple linear regression analyses in the CIWs (n = 444) and NCIWs (n = 1,347) separately. Interaction terms were included to detect differences between the two groups.
  
  
  RESULTS
  The results indicated that the CIWs had less favourable scores on the three health-related characteristics. Also, the CIWs scored less favourably than the NCIWs on almost all the work-related characteristics. In the two groups, negative work-related aspects, such as higher work pressure, contributed most to explaining the variance in the health-related characteristics. However, in the CIWs, fatigue was not explained by the work-related aspects as much as in the NCIWs. In the CIWs, the association between unpleasant treatment and the health-related characteristics was stronger than in the NCIWs, but there were indications that autonomy, possibilities for learning and social support from superiors also played an important role.
  
  
  CONCLUSIONS
  CIWs perceived more fatigue, emotional exhaustion and health complaints than NCIWs. There were different patterns of associations between work- and health-related characteristics in the NCIWs and CIWs. Future studies on associations between work-related characteristics and health should take the presence of chronic disease into account.
