Abstract

It is not always convenient or even possible to obtain self-reported weight for older adults, in particular for those with cognitive impairment, dementia, or several physical impairments, resulting in reliance on proxy respondents. Proxy reports of older adults’ health and functional status are often used in the clinical setting and population-based surveys, and the validity of such measures has been reported,1–3 but to the knowledge of the authors of this letter, the validity of proxy-reported weight specifically for older adults has not been examined.
