Poor physical performance is a strong predictor of mortality in older adults, thus, physical performance measures are often used as clinical indicators of well-being. However, it is unknown whether this association persists in those 90 years and older, the oldest old, where mutimorbidity is common. We investigated the association between physical performance and mortality in an oldest-old cohort. We assessed physical performance using the Short Physical Performance Battery (SPPB), which is comprised of balance (side-by-side stand, semi-tandem stand, and tandem stand), gait speed(4MWT), and repeated chair stand tests. We also measured balance and gait using the Tinetti Scale and grip strength using a dynamometer. Our outcome was all-cause mortality. We examined the association between physical performance and mortality using Cox regression models adjusting for baseline age and sex. Poor physical performance continues to be an effective clinical indicator of high mortality risk in the oldest segment of the population.
