Vision Impairment and the Population Attributable Fraction of Dementia in Older Adults.

ABSTRACT:

Importance

Vision impairment is a potentially modifiable risk factor for dementia. Although few prior studies have estimated the contribution of vision impairments to dementia, none have reported on multiple objectively measured vision impairments (eg, distance and near visual acuity and contrast sensitivity) in a nationally representative sample of older adults.

Objective

To quantify population attributable fractions of dementia from objective vision impairments in older adults, stratified by age, self-reported sex, self-reported race and ethnicity, and educational attainment.

Design, setting, and participants

This was a population-based cross-sectional analysis in the National Health and Aging Trends Study, which gathers nationally representative information on Medi
