Health, Medicine, and Social Epidemiology (9A) Practice Test

A health insurer analyzed diabetes-related amputations and found higher rates among members living in neighborhoods with low food access (few grocery stores with fresh produce). The insurer is considering a subsidy for healthy food delivery. The team frames the issue as a social epidemiology problem in which environmental constraints shape chronic disease management. Which prediction best aligns with this framing?

A hospital system examined 30-day readmission after heart failure hospitalization. Patients were grouped by neighborhood deprivation index (NDI) based on address at discharge. The system found higher readmission among patients from high-NDI areas despite similar in-hospital treatment protocols. The quality team proposes that social epidemiology can identify mechanisms linking place-based disadvantage to outcomes through access to resources and follow-up care. Which scenario best illustrates the mechanism implied by this principle?
