Epidemiology of Barrett's Esophagus: A Population Based Study

May 3, 2013 updated by: Prasad G. Iyer, Mayo Clinic

To assess attitudes toward screening for esophageal adenocarcinoma (EAC) and Barrett's esophagus (BE) in the community.

To develop a population based clinical risk factor prediction model for the diagnosis of BE and identify novel risk factors for BE which would make population based screening more efficient. This will be an important first step in identifying the target population for BE screening, another crucial component of making screening feasible and efficient

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
The primary outcome from the survey will be the proportion of patients willing to undergo an esophageal capsule study compared to those willing to undergo an endoscopic procedure (Esophagogastroduodenoscopy or transnasal endoscopy)
Time Frame: 18 months
18 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Study established (age, gender, ethnicity, reflux) and potential risk factors (sleep apnea, visceral adiposity, Helicobacter pylori infection, Metabolic Syndrome)to develop a clinical risk factor model for diagnosis of Barrett's esophagus(BE).
Time Frame: 18 months

Metabolic Syndrome (ATP III criteria, JAMA 2001; 285: 2486-97.) defined as a combination of clinical disorders that includes the presence of three or more of the following indicators:

  1. abdominal obesity (waist circumference > 102 cm in men, > 88 cm in women);
  2. high triglyceride level (≥ 150 mg/dL);
  3. low level of high density lipoprotein (< 40 mg/dL in men; < 50 mg/dL in women);
  4. high blood pressure (≥ 130/85 mmHg);
  5. high fasting plasma glucose (≥ 110 mg/dL).
18 months
