Description
Summary:Background: Frailty and body mass index (BMI) are known to be predictive of late life mortality, but little is known about the combined effects of frailty and BMI on mortality. Objective: This study investigated the influence of frailty status and BMI category on mortality in older adults. Methods: Data were from the Living Profiles of Older People Survey, a national survey of community-dwelling older people in Korea, with a baseline study of 11,844 Koreans aged 65 years and older in 2008 and a 3-year follow-up for mortality.

BMI (kg/m 2 ) was classified as underweight (
