title: When job stress threatens Chinese workers: combination of job stress models can improve the risk estimation for coronary heart disease--the BADCAR study.
abstract: OBJECTIVE
  To examine the association between job stress assessed by job demand control (JDC) model and effort-reward imbalance (ERI) model, and coronary heart disease (CHD) among Chinese workers.
  
  
  METHODS
  The study enrolled 388 subjects undergoing angiography. Job stress was assessed by JDC and ERI models. The association between job stress and CHD was analyzed by logistic regression.
  
  
  RESULTS
  Compared with low level group, high strain, especially high demand in JDC model, increased CHD risk with odds ratio of 2.0 (P < 0.05), and 5.0 (P < 0.001), respectively; by combing exposure to both high job strain and high ERI, a substantially increased CHD risk was observed (adjusted odds ratio = 6.1, P = 0.001).
  
  
  CONCLUSIONS
  High job strain and demand increased the risk of CHD among Chinese workers. The combination of information from the two job stress models (JDC and ERI) substantially improved the risk estimation for CHD.
