Frailty across the spectrum of ankle-brachial index.

Abstract

We investigated the burden of frailty across the spectrum of ankle-brachial index (ABI < 0.9, 0.9 ≤ ABI < 1.1, 1.1 ≤ ABI < 1.4 and ≥1.4) using data from the National Health and Nutritional Examination Survey (NHANES) in respondents aged >50 years. Criteria used to identify frailty status included weight loss, slow walking speed, weakness, exhaustion, and… (More)
