NCT01570842

Brief Summary

Is waist to hip ratio (WHR), waist circumference (WC), (as markers of visceral adiposity) associated with an increase in acidic and non acidic reflux as well as systemic inflammation involving esophageal mucosa, thereby increasing esophageal injury and predisposing to subsequent development of Barrett's esophagus (BE)?

Outcome Measures

Primary Outcomes (1)

  • Correlate Anthropometry with number of acid reflux episodes

    To correlate measures of central obesity waist/hip ratio (WHR) and waist circumference (WC) with number of reflux episodes (acidic and non acidic), and other measures of acid/non acid reflux. Stratify by use of proton pump inhibitors (PPIs).

    1 year

Study Arms (1)

Anthropometric Measurements; Tissue Samples

OTHER

All participants will have their waist circumference and waist to hip ratio taken as a measurement of central obesity. Participants undergoing clinically indicated upper endoscopy and who consent to providing tissue samples will have 8 tissue samples taken for future research purposes.

Other: Anthropometric measurementsProcedure: Tissue samples

Interventions

All participants will have their waist circumference and waist to hip ratio taken as a measurement of central obesity.

Anthropometric Measurements; Tissue Samples

Participants undergoing clinically indicated upper endoscopy and who consent to providing tissue samples will have 8 tissue samples taken for future research purposes.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects over the age of 18 undergoing clinically indicated 24 hour pH impedance and/or pH studies. Many will also undergo clinically indicated endoscopy, and consent for acquiring tissue samples for future biomarker staining tests will be obtained.
  • Able to give informed consent

You may not qualify if:

  • Subjects with a prior history of esophageal surgery, or diagnosis of BE.
