title: Age- and sex-specific yield of Barrett's esophagus by endoscopy indication.
abstract: BACKGROUND
  Barrett's esophagus is a precursor of esophageal adenocarcinoma, both of which are associated with GERD. Screening GERD patients for Barrett's esophagus has been suggested, but it is not known which patients should be screened and at what age.
  
  
  OBJECTIVE
  To determine the age-specific yield of endoscopy for Barrett's esophagus stratified by sex and indication for endoscopy.
  
  
  METHODS
  Retrospective cross-sectional study.
  
  
  METHODS
  National Endoscopic Database of the Clinical Outcomes Research Initiative (CORI).
  
  
  METHODS
  A total of 155,641 patients undergoing their first endoscopy at one of the CORI sites for clinical indications.
  
  
  METHODS
  Age-specific yield of Barrett's esophagus.
  
  
  RESULTS
  Among white men with GERD, the yield of Barrett's esophagus increases steeply from early adulthood (2.1% in the third decade of life) to middle adulthood (9.3% in the sixth decade) and then plateaus (the difference for the eighth decade minus the sixth decade is -1.1%; 95% CI, -3.9% to 1.7%). There is no difference in the yield of Barrett's esophagus between middle-aged white women with GERD and white men without GERD (difference is -0.46%; 95% CI, -1.23% to 0.31%).
  
  
  CONCLUSIONS
  Possible bias by selection for endoscopy and the potential for misclassification of GERD status.
  
  
  CONCLUSIONS
  The yield of upper endoscopy for the diagnosis of Barrett's esophagus increases rapidly among white men with GERD until approximately age 50 and then reaches a plateau. White women with GERD are at no increased risk compared with white men without GERD.
