You are investigating the role of physical activity in heart disease, and your data suggest a protective effect. While presenting your findings, a colleague asks whether you have thought about confounders, such as factor X. Under which of the following conditions could this factor have confounded your interpretation of the data?
- A. It is a risk factor for some other disease, but not heart disease.
- B. It is a risk factor associated with the physical activity measure and heart disease.
- C. It is part of the causal pathway by which physical activity affects heart disease.
- D. It has caused a lack of follow-up of test subjects.
Correct Answer: B
Rationale: A confounder must be associated with both the exposure (physical activity) and the outcome (heart disease), and it should not lie on the causal pathway between them.
