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; (3) To identify the importance of race and identify risk factors for gastroesophageal reflux disease unique to the African Americans population by using a control group composed of Caucasians; 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 ] [ Designated as safety issue: No ]
    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 750 African Americans and have 250 caucasian controls all from the same community in North Philadelphia.

Secondary Outcome Measures:
  • Longitudinal study on incidence of reflux disease [ Time Frame: 10 years ] [ Designated as safety issue: No ]
    We will follow the established cohort over 10 years to look at the incidence of reflux disease as well as the incidence of functional bowel disorders in African Americans.
