Sample interview questions: Can you discuss the concept of attributable risk and its relevance in epidemiological research?
Sample answer:
Attributable Risk:
-
Attributable risk is a measure of the proportion of disease in a population that can be attributed to a specific exposure or risk factor.
-
It quantifies the excess risk of disease that is specifically caused by the exposure of interest, taking into account the overall incidence of the disease in the population.
Relevance in Epidemiological Research:
- Assessing Causal Relationships:
- By calculating attributable risk, epidemiologists can estimate the causal effect of an exposure on the occurrence of a disease.
-
A high attributable risk suggests that the exposure is a major contributor to the disease burden and strengthens the evidence for causation.
-
Quantifying Disease Burden:
- Attributable risk provides a quantitative estimate of the proportion of disease cases that can be prevented by eliminating or reducing the exposure.
-
This information is valuable for public health planning and resource allocation, as it helps prioritize interventions and policies aimed at reducing the disease burden.
-
Evaluating Public Health Interventions:
- Attributable risk can be used to evaluate the effectiveness of public health interventions aimed at reducing exposure to a risk factor.
-
By comparing the attributable risk before and after the intervention, researchers can assess the impact of the intervention in reducing the disease burden.
-
Identifying High-Risk Populations:
- Attributable risk can help identify population subgroups that are at higher risk of developing a disease due to a specific exposure.
-
This information can be used to target preventive measures and interventions to these high-risk groups, potentially reducing the overall disease burden.
-
Informing Policy and Decision-Making:
- Attributable risk estimates provide valuable evidence for policym… Read full answer
