title: Circumstances at HIV diagnosis and progression of disease in older HIV-infected Americans.
abstract: OBJECTIVE
  This study identified age-related differences in diagnosis and progression of HIV by analyzing a nationally representative sample of HIV-infected adults under care in the United States.
  
  
  METHODS
  We compared older (> or = 50 years) and younger participants stratified by race/ethnicity. Regression models controlled for demographic, therapeutic, and clinical factors.
  
  
  RESULTS
  Older non-Whites more often had HIV diagnosed when they were ill. Older and younger patients were clinically similar. At baseline, however, older non-Whites had fewer symptoms and were less likely to have AIDS, whereas at follow-up they had a trend toward lower survival.
  
  
  CONCLUSIONS
  Later HIV diagnosis in non-Whites merits public health attention; clinical progression in this group requires further study.
