Visual impairment predicts greater declines in physical performance over time: the Health, Aging and Body Composition Study.

ABSTRACT:

Background

Poor vision has been associated with physical dysfunction and falls in older adults, but it is not known whether particular types of visual impairment (VI) may predict greater rates of decline in mobility over time in older adults.

Methods

Multi-center longitudinal cohort study of 2219 older adults (mean age = 75.5 years; 52.4% female; 37.4% black) who completed self-reported (visual function questions (VFQ)) or performance-based (visual acuity (VA); log contrast sensitivity (LCS); stereoacuity (SA)) vision testing at year 3 and the short physical performance battery (SPPB) at year 4. Analyses were performed including all 2219 participants (Cohort A) and 1795 of these participants with SPPB ≥ 9 (Cohort B) at year 4. Separate linear mixed models were constructed to
