Which statement best describes how environmental and social factors influence population health outcomes?

• A. Environment affects exposure to disease, but social determinants have no effect on health.
• B. Social determinants determine health outcomes independent of environment.
• C. Environment influences exposure to disease and social determinants influence access to care, and together they shape health outcomes.
• D. Genetics alone determine health outcomes.

Answer: (C)

The main idea is that population health outcomes arise from how both environmental exposures and social conditions shape risk and resources. The environment affects what people are exposed to—pollution, housing quality, water and food safety, occupational hazards—while social determinants influence access to care, affordability, education, and living conditions that support health. Together, these factors interact to determine outcomes: even with certain exposures, good access to care and supportive social conditions can improve outcomes; conversely, poor exposure contexts and limited resources can worsen them. That’s why this statement—environment influencing exposure and social determinants influencing access to care, and together shaping health outcomes—best captures the concept. The other options miss how environment and social factors work together, or misstate the role of genetics.
