Implication
Low AAI prevalence does not support routine screening in elderly Japanese men; leaves open prospective validation of risk factor associations.

Outcome
Prevalence of ankle-arm index (AAI) <0.90 and its association with cardiovascular risk factorssurrogate
In elderly Japanese men, despite a low overall prevalence of peripheral artery disease, a low ankle-arm index (<0.90) strongly correlates with traditional cardiovascular risk factors such as hypertension, smoking, and history of stroke.
Limitations
- Low statistical power to detect relationship with diabetes due to low prevalence in Japan
- Possible overestimation of ankle blood pressure in obese men due to larger ankle circumferences
- Cross-sectional design limits causal inference
