The World Health Organization (WHO) and the American Diabetes Association (ADA) have established criteria for diagnosing diabetes and prediabetes using OGTT results: - Normal: Fasting glucose What Are the Epidemiological Applications of OGTT?
OGTT has several epidemiological applications: 1. Prevalence Studies: By administering OGTT to a representative sample, researchers can estimate the prevalence of diabetes and prediabetes in a population. 2. Incidence Studies: Longitudinal studies using OGTT can track the incidence of new diabetes cases over time. 3. Risk Factor Analysis: OGTT data can be used to identify risk factors associated with glucose metabolism disorders, such as obesity, physical inactivity, and genetic predisposition. 4. Public Health Interventions: Identifying high-risk populations through OGTT allows for the implementation of targeted public health interventions, such as lifestyle modification programs and early screening initiatives.
