title: Discrepancy between chronological age and felt age: age group difference in objective and subjective health as correlates.
abstract: OBJECTIVE
  Guided by the social comparison theory, we examined correlates of the discrepancy between chronological and felt ages in three age groups of community-dwelling older adults: 65 to 69, 70 to 79, and 80 and older.
  
  
  METHODS
  Data from the National Health and Aging Trends Study and linear regression models were used to test the hypothesis that age discrepancy would be significantly associated with objective health indicators among those in the 65 to 69 and 70 to 79 age groups but not among the 80+ group.
  
  
  RESULTS
  Objective health indicators were significantly associated with age discrepancy only in the 70 to 79 age group, while subjective health perceptions and psychological well-being were significantly associated with age discrepancy in all age groups.
  
  
  CONCLUSIONS
  The correlates of the discrepancy in the 65 to 69 age group appear to resemble those in the 80+ group more than those in the 70 to 79 age group. Further research is needed to identify the determinants of age group differences.
