Key result
Older age is linked to ~2-fold higher odds of PAD per decade.
Why the study?
There is little data to assess the prevalence of different phenotypes of vascular disease in the very elderly population.
Population
Over 3.6 million self-referred participants in the United States from 2003 to 2008
Comparison
Vascular disease prevalence across different age decades
Design
Cross-sectional study using screening ankle brachial indices and ultrasound imaging

The prevalence of peripheral artery disease, carotid artery stenosis, and abdominal aortic aneurysm increases dramatically with advanced age, affecting over 30% of nonagenarians.

The prevalence of peripheral artery disease, carotid artery stenosis, and abdominal aortic aneurysm increases dramatically with advanced age, affecting over 30% of nonagenarians.
Savji et al. (2013) conducted a cross-sectional in Vascular disease (n=3,600,000). Advanced age (per decade of life) vs. Younger age was evaluated on Peripheral artery disease (PAD) (OR 2.14, 95% CI 2.12-2.15). Advanced age was associated with increased odds of peripheral artery disease (OR 2.14 per decade), carotid artery stenosis (OR 1.80), and abdominal aortic aneurysm (OR 2.33).
