Frailty, a condition often characterized by a slower walk and weaker hand grip, is projected to increase significantly in the coming years. This trend is closely linked to the aging of the population, with experts noting that 2021 marked the year the leading edge of the Baby Boom generation turned 75 – an age at which many age-related diseases typically emerge.
"It's the demographic imperative," said Dr. Kenneth Rockwood, a professor of medicine at Dalhousie University in Canada who co-developed diagnostic scales for frailty. "In 2021 the leading edge of the baby boom generation turned 75 years old, and 75 is the age at which most of the diseases of aging take off. So now frailty is not some mystical, mythical far-off thing."
Despite its increasing prevalence, frailty is not considered an inevitable part of aging and can, to some extent, be reversed or mitigated. Identifying frailty typically involves a comprehensive geriatric assessment, where a healthcare team evaluates various aspects of an older adult's health.
However, certain signs can indicate frailty, some of which individuals might notice themselves. These can include a slower walking speed, defined in one study as less than approximately 0.8 meters per second. Another indicator is the "timed up and go" test, where taking more than 10 seconds to stand from a chair, walk a short distance, turn, return, and sit down may signal frailty.
"You can't tell at a glance, but it doesn't take that long [to detect] if you know what questions to ask…if you can see the person move," Rockwood explained. The condition can lead to unexpected complications, underscoring the importance of awareness and early detection.
