title: Differences in health-related quality of life by sleep duration and subjective oral health in Korean adults with coronary artery disease.
abstract: BACKGROUND
  Health-related quality of life management for patients with coronary artery disease should be considered in the context of sleep and oral health, as both associated with heart health.
  
  
  OBJECTIVE
  To identify differences in health-related quality of life by sleep duration and subjective oral health among these patients and to examine factors influencing health-related quality of life.
  
  
  METHODS
  A descriptive cross-sectional design using secondary data from the 2013 Korea Community Health Survey. Data were collected from August 16, 2013, to October 31, 2013, with 6454 adults with coronary artery disease aged 19 or older.
  
  
  RESULTS
  We observed a significant difference in health-related quality of life by sleep duration, subjective oral health, and chewing discomfort. A hierarchical regression analysis identified factors affecting health-related quality of life: no smoking and no economic activity had negative effects, and highest level of education, having a spouse, no hypertension, no dyslipidemia, no arthritis, good subjective oral health, and no chewing discomfort had positive effects.
  
  
  CONCLUSIONS
  Good subjective oral health and no chewing discomfort significantly predicted health-related quality of life among study patients. To improve health-related quality of life of these patients, promotion and education regarding regular dental clinic visits is needed to ensure early interventions.
