Introduction

More than 25% of adults age 65 and over fall every year in the United States. Among older adults who fall, approximately 40% experience two or more falls in the same year. These falls negatively impact older adults’ mobility, function and independent living. Falls are also the leading cause of injury deaths among U.S. older adults. In 2018 alone, falls and related injuries among older adults resulted in an estimated 3 million emergency department visits, more than 950,000 hospitalizations, and approximately 32,000 deaths.

Falls often result from a combination of risk factors. These include physical or functional risk factors, such as impaired balance and gait, pain, overall frailty; medical risk factors, such as multiple chronic health conditions, taking multiple medications, especially psychotropic medications; and psychological risk factors, such as depression, anxiety, and fear of falling. Other factors include sensory and cognitive risk factors and environmental circumstances (for example, trip hazards in the home).

In recurrent falls – that is, two or more falls in a year or over a given timeframe – previous falls are the most significant risk factor, in addition to the combination of risk factors described above. Moreover, recurrent falls generally have greater negative impact on older adults’ health and functioning compared to a single fall. This is because repeated falls increase the risk of injury, fracture, associated pain, fear of falls, disability, and death.

This brief summarizes findings from a recent study [1] that used longitudinal data from a nationally representative sample of U.S. adults age 70 and older. The authors examined whether health characteristics (physical or functional, psychological, and cognitive) and exercise patterns were associated with a single fall and recurrent falls over 3 years. They also calculated the risk of hospitalization based on how many falls an older adult had. Finally, they examined who was more likely to have one or more falls in 2020-2021 among those who had no fall and those who had one or more falls in 2019.

Key Findings

• Rates of falling were high among adults age 70 and older during the 3-year study period (2019-2021).
  • 57% experienced at least 1 fall
  • 34% experienced 2+ falls; showing that 60% of those who fell had recurrent falls
• Older adults who started exercising after a fall in 2019 were less likely to experience a recurrent fall in the following 2 years. Those who exercised in both 2019 and 2020 were the least likely to experience a subsequent fall (see figure).
  • Exercise included walking and other activities such as swimming, running or biking.
• Older adults with recurrent falls had worse physical or functional health and more psychological health problems in 2019 compared to older adults who did not fall.
  • But, there were no significant health differences between older adults with a single fall and those with no falls.
• Both a single fall and recurrent falls over the 3 years were associated with a higher risk of hospitalization in 2021, after taking other risk factors into account.
• Racial and ethnic differences in the risk of single and recurrent falls were found.
  • Black older adults had a lower risk of any fall over 3 years, compared to their White, non-Hispanic peers.
  • However, among those who fell in 2019, Black older adults and White older adults had similar risks of a recurrent fall in the following 2 years.
  • In contrast, Hispanic older adults who fell in 2019 had a higher risk of a recurrent fall in the following 2 years, compared to their White peers.

Data and Methods

The authors used data from the 2019–2021 U.S. National Health and Aging Trend Study (NHATS). NHATS collects data annually from a nationally representative panel of Medicare beneficiaries. The initial people sampled, who were age 65 and over, were first interviewed in 2011. An additional sample was added in 2015 to replenish those were lost to follow up. This study included 3,063 people who represent approximately 28.3 million Medicare beneficiaries age 70 and over who were living in their own homes or residential care communities (but not in nursing homes) in all three years and reported answers themselves.
