DESCRIPTION: Minimal data exists on the prevalence of gastroesophageal reflux disease in minority populations. Specific objectives of this K24 research project are to: (1) Provide an estimate of the prevalence of gastroesophageal reflux disease in an urban, African American population; (2) Determine whether specific risk factors including diet, tobacco use, physical activity, and psychosocial stress are important in the targeted population. We will also measure height, weight, and waist/hip circumference to determine the impact of central obesity on reflux. PUBLIC HEALTH RELEVANCE: This research will help doctors to understand the frequency and risks for esophageal reflux disease (heartburn) in African Americans.

Primary Outcome Measures:
  • Epidemiologic Factors Associated With Prevalent Reflux Disease. [ Time Frame: Two years ]
    Patients will complete a series of standardized questionnaires to determine the prevalence of reflux disease and risk factors for its development. We will query diet, depression, drug, tobacco, and alcohol use as well as a variety of other factors. We will study 450 African Americans living in North Philadelphia.
