Disability-Free Life Increasing Among Older Americans, Study Finds
A new study has revealed a significant rise in the number of older Americans living without any disability, suggesting an encouraging trend in aging and overall health. Published in Archives of Gerontology and Geriatrics Plus, the research found that from 2008 to 2017, the proportion of U.S. adults aged 65 and older without serious disabilities—including memory, hearing, vision, and functional impairments—rose from 61% to 65%.
While this four-percentage-point increase may appear modest, it translates to 2.07 million fewer older Americans experiencing serious disabilities in 2017 than would have been expected had the 2008 prevalence remained unchanged. The findings highlight improvements in quality of life and potential reductions in long-term healthcare demands.
“Such a dramatic improvement over a short period is extremely encouraging,” said senior author Esme Fuller-Thomson, Director of the University of Toronto’s Institute for Life Course & Aging. “Older adults without disabilities are less likely to require extensive healthcare services and can maintain greater independence.”
The study analyzed data from 5.4 million respondents over ten years, collected through the nationally representative American Community Survey. Researchers defined individuals as disability-free if they reported no serious difficulty with memory, vision, hearing, daily activities such as dressing, or functional mobility like walking and climbing stairs.
Interestingly, the study found a notable shift in gender trends. In 2008, men were more likely to be disability-free than women (62.7% vs. 59.4%). However, women experienced a steeper improvement rate over the decade, closing the gap by 2017.
Researchers suggest that higher educational attainment among post-war generations may have contributed to this progress. Education is linked to healthier lifestyle choices, such as reduced smoking rates, and access to less physically demanding jobs, which can lower the risk of late-life disabilities.
However, the study notes that gains in disability-free living were mainly seen in those 75 and older, with little improvement among younger seniors (65-74). Researchers speculate that higher obesity rates among Baby Boomers may slow future progress.
As life expectancy rises, understanding the factors influencing disability-free aging will be crucial in shaping policies and healthcare strategies for an aging population.
