Body Mass Index, Waist Circumference, and Waist-to-Hip Ratio as Predictors of Mortality in Nonagenarians: The Vitality 90+ Study

Abstract

In nonagenarian men, low BMI and low WC predict increased mortality. In nonagenarian women, waist-to-hip ratio alone and adjusted for BMI is positively associated with mortality. The potential positive effects of overweight combined with WC warrant more detailed analyses in larger data. In all, future studies are needed to better understand the health and functional consequences of body composition among the oldest old.
