Poor Vision Linked to Physical Decline, Cognitive Problems in Older Adults
New research has found that as older adults’ vision declines, their participation in physical and mental activities also declines.
In a study published in the Journal of the American Geriatrics Society, researchers from German universities and medical schools studied 2,394 adults between the ages of 77 and 101 to learn how vision issues affected their physical and cognitive abilities.
Researchers interviewed the participants every 18 months between 2003 and 2012. They asked how often they were physically active and what activities they performed, including cycling, long walks, swimming, gymnastics, garden work, or taking care of people.
The researchers also asked how often the participants read, wrote, played music, worked on crossword puzzles, did memory training, played card games, board games, or chess, and how frequently they engaged in social activities.
Participants were asked to rate their visual impairment on a scale that included “no impairment,” “mild impairment,” or “severe or profound impairment.”
Researchers also asked whether participants had chronic conditions, such as diabetes or stroke, and how severe the conditions were.
During a second group of interviews 36 months after the study began, most of the participants were women whose average age was 82. They were mostly single, widowed, or divorced, and lived alone. Nearly 80 percent of the participants reported having no visual impairment.
But visual impairments increased over time, and the frequency of the participants’ physical and mental activities decreased — especially for activities such as cycling, long walks, gymnastics, and gardening.
Solving crossword puzzles and reading also decreased as vision problems worsened, the researchers discovered.
The researchers concluded that when older adult’s vision declines sharply, their participation in physical and mental activities also declines.
The research team suggested that, since most vision loss is preventable, strategies to postpone vision loss might also help delay physical and mental decline among older adults.
