Performance-based measures of physical function as mortality predictors: Incremental value beyond self-reports.

ABSTRACT:

Background

Although previous studies have indicated that performance assessments strongly predict future survival, few have evaluated the incremental value in the presence of controls for self-reported activity and mobility limitations.

Objective

We assess and compare the added value of four tests - walking speed, chair stands, grip strength, and peak expiratory flow (PEF) - for predicting all-cause mortality.

Methods

Using population-based samples of older adults in Costa Rica (n = 2290, aged 60+) and Taiwan (n = 1219, aged 53+), we estimate proportional hazards models of mortality for an approximate five-year period. Receiver Operator Characteristic (ROC) curves are used to assess the prognostic value of each performance assessment.
