Which of the following best describes a model that demonstrates the progression of disease from prepathogenesis through disease outcome?

c. Natural history model
d. Wheel model

ESSAYBID ANSWER

ANS: C
The natural history of disease model explains disease from prepathogenesis through resolution of the disease process. The epidemiological model involves the epidemiological triangle: agent, host, and environment. The ecosocial model emphasizes the role of evoloving macro-level socio-environmental factors to understand health and illness. The wheel model subscribes to multiple-causation rather than single-causation disease theory, and is more useful in analyzing complex chronic conditions and identifying factors that are amendable to intervention.
