Beyond the Clinic Walls

While modern medicine celebrates advancements in genomics and artificial intelligence, public health data consistently reveals a sobering truth: up to 80% of a person’s health outcomes are determined by conditions outside clinical settings—known as the Social Determinants of Health (SDOH).

What is Health Equity?

Health equity is the state in which every person has a fair and just opportunity to attain their highest level of health. It requires removing obstacles such as poverty, discrimination, environmental hazards, and lack of access to nutritious food and quality healthcare systems.

Key Determinants Shaping Daily Well-being

  • Economic Stability: Income security, employment conditions, and healthcare insurance accessibility.
  • Neighborhood & Built Environment: Access to clean water, green parks, fresh produce stores, and safe housing.
  • Health Literacy & Education: Ability to comprehend medical guidelines and navigate complex digital provider portals (e.g. MyChart, Athena, IU Health).
  • Social & Community Context: Civic participation, social cohesion, and mitigation of chronic psychological stress.
