OBJECTIVES: To determine whether falling would be a
marker for future difficulty with activities of daily (ADLs)
that would vary according to fall frequency and associated
injury.
DESIGN: Longitudinal analysis.
SETTING: Community.
PARTICIPANTS: Nationally representative cohort of
2,020 community-living, functionally independent older
adults aged 65 to 69 at baseline followed from 1998 to
2008.
MEASUREMENTS: ADL difficulty.
RESULTS: Experiencing one fall with injury (odds ratio
(OR) = 1.78, 95% confidence interval (CI) = 1.29–2.48), at
least two falls without injury (OR = 2.36, 95% CI = 1.80–
3.09), or at least two falls with at least one injury
(OR = 3.75, 95% CI = 2.55–5.53) in the prior 2 years was
independently associated with higher rates of ADL difficulty
after adjustment for sociodemographic, behavioral, and
clinical covariates.
CONCLUSION: Falling is an important marker for future
ADL difficulty in younger, functionally independent older
adults. Individuals who fall frequently or report injury are
at highest risk. J Am Geriatr Soc 61:96–100, 2013.

D
isability in older adults is an important public health
concern. Recent studies document increasing disability
in older Americans after 3 decades of decline.

A recent
analysis of the National Health and Nutrition Examination
Surveys (NHANES) concluded that the rate of new disabil-
ity increased in individuals aged 60 to 69 between 1998 and
2004. Minorities and overweight or obese individuals
experienced higher rates of disability; the overall trend was
independent of other measured sociodemographic factors,
chronic conditions, and health behaviors.

This finding
suggests that younger groups of older adults may spend an
increasing proportion of their lives with disability.
Falling is a common event in older adults and a
known risk factor for future disability in individuals aged
75 and older.

Falls can result in injury, higher rates of
skilled nursing home placement, high medical costs, and
loss of patient confidence leading to voluntary restriction
of activity.

The relationship between falls and disability
has not been systematically explored in younger groups of
healthier older adults. Many of these individuals are newly
retired and eligible for Medicare and may have the most
to gain from earlier identification for future disability.
The relationship between falls and difficulty with activi-
ties of daily living (ADLs) was assessed in a nationally repre-
sentative cohort of functionally independent, community-
living older adults aged 65 to 69 at baseline followed for
10 years. It was hypothesized that falling would be an
important marker of future ADL difficulty that would vary
according to fall frequency and associated injury.
METHODS
Study Population
Data from the Health and Retirement Study (HRS), a
nationally representative, biennial longitudinal survey of
adults aged 51 and older in the United States designed to
evaluate the socioeconomic and health dynamics of older
adults, were analyzed. The National Institute on Aging
