title: [Physical activity and sleep patterns in elderly who visited a community senior center].
abstract: OBJECTIVE
  The purpose of this study was to identify the relationship between physical activity and sleep patterns of the elderly.
  
  
  METHODS
  The subjects of this study were 154 elderly who visited a community senior center in Korea. Data was collected by an interview and a self reported questionnaire, during the period from June to October, 2006. Physical activity was measured by IPAQ Korean version (2006), and sleep pattern by Korean Sleep Scale A developed by Oh et al. (1998).
  
  
  RESULTS
  The prevalence of chronic illness in the subjects was 73.4 %. The mean time of vigorous activity was 6.62+/-31.27 minutes/day during the past week. Moderate activity time was 28.85+/-50.31 minutes/day and walking time was 28.85+/-50.3 minutes/day. The total sleep time was 397.63+/-111.53 minutes/day. Physical activity of the elderly significantly correlated with sex, chronic illness, job, and sleep patterns of the elderly. Stepwise multiple regression analysis revealed that the most powerful predictor of sleep pattern was the satisfaction of sleep. A combination of the number of chronic illnesses, moderate physical activities (MET), and total time of sleep accounted for 44.4% of the sleep pattern.
  
  
  CONCLUSIONS
  Moderate physical activity is more effective than vigorous physical activity for improving the sleep quality of the elderly.
