Abstract 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. Frailty was categorized as not frail, prefrail, and frail, based on five indicators (weight loss, exhaustion, physical activity, walking speed, and grip strength). BMI (kg/m2) was classified as underweight (
