title: Effect of physical activity after a cardiac event on smoking habits and/or Quetelet index.
abstract: OBJECTIVE
  To further elucidate earlier findings, the present study investigated whether physical activity could serve as a positive stimulus to modify other changeable cardiac risk factors.
  
  
  METHODS
  Participants were 140 patients who had completed a cardiac rehabilitation programme focused on physical activity. Their present level of physical activity, smoking habits and Quetelet index were investigated as well as that before the cardiac event, in retrospect. Current feelings of anxiety and depression were also assessed. Participants were divided into two categories according to their present level of physical activity after finishing the rehabilitation programme, compared with that before the cardiac event.
  
  
  RESULTS
  It appeared that the more physically active category contained more smokers. Although many of them had quitted smoking, significantly more persisted in their smoking habits compared with the patients who did not increase their physical activity. Significantly less depression was found in the more active patients.
  
  
  CONCLUSIONS
  Although it could not be confirmed that physical activity stimulated a positive change in smoking and Quetelet index, the more active patients appeared to be less depressed.
