Bidirectional Association between Visual Impairment and Dementia Among Older Adults in the United States Over Time.

ABSTRACT:

Purpose

Although visual impairment (VI) has been associated with worse cognitive performance among older adults, the temporal relationship between the 2 remains subject to debate. Our objective was to investigate the longitudinal impact of VI on cognitive function and vice versa.

Design

Retrospective, time-to-event study.

Participants

National Health and Aging Trends Study (NHATS) participants from 2011 to 2018 cycles.

Methods

A total of 10 676 participants aged 65 years and older were included. Cox proportional hazards regression models evaluated the impact of baseline VI on subsequent dementia and impact of baseline dementia on subsequent VI. Models were adjusted for potential confounding variables, including demographics, clinical comorbidities, and hearing
