Which best describes the advantage of the ecosocial epidemiology model over both the web of causation model and the epidemiological triangle model? (Select One that does not apply..)

Correct Answer: B

Rationale: The ecosocial approach challenges both the individually focused risk factor approach and molecular epidemiology (sequencing of genes to improve individual susceptibility), because it emphasizes the role of macro-level socioenvironmental factors, especially complex political and economic forces in health and illness.

Correct Answer: B

Rationale: Morbidity (B) is disease frequency or burden (e.g., illness rates). A is mortality, C is incidence, D is population at risk.

Correct Answer: D

Rationale: Randomized controlled trials (D) assign interventions randomly to test effects (e.g., drug trials). A, B, and C are observational.

Correct Answer: A

Rationale: Secondary attack rate (A) measures infection among contacts of a primary case (e.g., household spread). B, C, and D are broader or vague.

Correct Answer: B

Rationale: Cross-sectional studies (B) measure prevalence at one time (e.g., obesity rates). A requires time, C and D need longitudinal data.
