What are causes of racial/ethnic health disparities?

• A. Weather patterns
• B. Genetic differences only
• C. Individual lifestyle choices only
• D. Structural factors such as socioeconomic inequality, access barrier, systemic bias

Answer: (D)

Racial/ethnic health disparities arise from how society structures opportunities, resources, and access to care—not from biology or personal choices alone. Structural factors like socioeconomic inequality, barriers to high-quality care, and systemic bias shape who can afford prevention, receive timely treatment, and manage chronic conditions. These social determinants influence where people live, work, learn, and how much stress they experience, all of which directly affect health outcomes and create unequal patterns across groups.

Weather patterns don’t inherently explain disparities tied to race or ethnicity, since they affect populations broadly rather than producing differences that align with racial/ethnic lines. Genetic differences, while relevant for certain conditions, do not account for the broad, persistent disparities seen in many health measures, and framing race as a genetic predictor overlooks the powerful role of social context. Individual lifestyle choices, too, are shaped by external circumstances—income, neighborhood resources, discrimination, and access barriers—so focusing only on personal choices misses how structural forces drive inequities.

Thus, structural factors such as socioeconomic inequality, access barriers, and systemic bias best explain racial/ethnic health disparities.
