The study analysed 2022 data from the National Health and Aging Trends Study, using a sample of 4,648 community-dwelling US Medicare beneficiaries aged 65 and older who completed visual function tests and a home environment instrument. Researchers emphasise that the combination of poor vision and hazardous home conditions greatly raises fall risk for older adults, and that this interaction matters more than either factor alone.
Specific findings included that nearly half (47%) of older adults lacked grab bars in the bathroom, more than half lived with at least one hazard, tripping hazards affected 9.5% of homes, broken flooring was present in 4.5%, and roughly 7% of homes had two hazards. Older adults with severe vision loss were three to four times more likely to fall when they lived in homes with hazards.
Researchers measured visual function and found that each one-line difference on the Snellen visual acuity chart was associated with a 31% increase in fall risk, while each one-line loss on the contrast sensitivity chart raised the risk by 14%. Coauthor Joshua Ehrlich urged that fall prevention should pair vision care with targeted home modifications. The paper appears in JAMA Opthalmology and was reported by the University of Michigan.
- Get regular eye exams and use the right glasses.
- Add grab bars and nonslip mats in bathrooms.
- Clear walking paths, fix damaged flooring and improve lighting.
