Evaluating Frailty in Seniors

Fifteen percent of older Americans living at home or in assisted living settings are frail, a diminished state that makes people more vulnerable to falls, chronic disease and disability. Another 45 percent are “pre-frail,” or at heightened risk of becoming physically diminished.

A study by the Johns Hopkins Bloomberg School of Public Health found frailty to be more prevalent in older people and more common among women and the poor. In addition, the study found wide regional differences in the U.S., with older people in central southern states more than three times as likely to be frail than those in the western states. The researchers also found significant racial differences, with blacks and Hispanics nearly twice as likely to be frail as whites.

The study was published in Journals of Gerontology: Medical Sciences.

Frailty, once thought of as a generalized state that befalls some people as they get older, is increasingly considered a medical process in and of itself. Frailty is thought to be exhibited by a set of symptoms including weakness, exhaustion and limited mobility. It often progresses separately from any underlying conditions, and is also common among patients with chronic diseases such as heart disease and diabetes, especially in their advanced stages.

Understanding frailty, and finding ways to prevent its onset or slow its progression, could improve older people’s quality of life by extending their so-called robust years. It could also increase their chances of surviving surgery, for example; previous research has suggested that older, frail patients are less likely to survive major surgical procedures. Reducing frailty could lower health care costs, since frail persons are prone to falls and falls often lead to hospitalization. Hospital care is the largest component of Medicare spending.

Of their findings, the authors were most surprised by the significant racial and regional differences, says study leader Karen Bandeen-Roche, PhD, the Frank Hurley and Catharine Dorrier Professor and Chair of the Department of Biostatistics at the Johns Hopkins Bloomberg School of Public Health. The study is believed to be the first that examines regional differences in frailty in the U.S.

“We can’t really explain the regional differences,” says Bandeen-Roche, who also co-directs the Johns Hopkins Older Americans Independence Center and is a Core Faculty member at the Johns Hopkins Center on Aging and Health. “We know there are health differences across the country, differences in diet and to some extent exercise habits. Observing the relatively low prevalence in the mountain west, you can imagine an active lifestyle might be a factor.” As for the racial differences, Bandeen-Roche says it’s too early to speculate and that they merit further study.
