OBJECTIVES: To determine whether musculoskeletal
pain increased risk for falls in older women with disabilities.
DESIGN: Prospective population-based cohort study.
SETTING: The city and county of the eastern area of Bal-
timore.
PARTICIPANTS: One thousand two women aged 65 and
older, participants in the Women’s Health and Aging
Study, representing the one-third of older women who
were living at home with disabilities, followed semiannu-
ally for 3 years beginning in 1991.
MEASUREMENTS: Pain was categorized into four groups
according to severity and location. Widespread pain was
defined as pain in the upper and lower extremities and in
the axial skeletal region, with moderate to severe pain in
at least one region ( 4 on a 10-point numeric rating
scale, 10 = excruciating pain). Moderate to severe lower
extremity pain that did not meet criteria for widespread
pain was the next category. The reference category was no
pain or mild pain in one site. The additional category of
“other pain” was pain that did not fit into the other three
groups. The occurrence of falls and fall-related injuries
were assessed at each interview.
RESULTS: Of the 940 women who participated in at
least one follow-up examination, 39% fell in first year; of
the survivors, 36% fell in Year 2, and 39% in Year 3. Af-
ter adjusting for several major risk factors for falls, women
with widespread pain had an increased likelihood of fall-
ing during follow-up (adjusted odds ratio (AOR) = 1.66,
95% confidence interval (CI) = 1.25–2.21) compared
with those with no or mild pain in only one musculoskele-
tal site. Women who had other musculoskeletal pain but
not widespread pain or lower extremity pain also had an
increased risk of falls (AOR = 1.36, 95% CI = 1.02–
1.82). Among women with musculoskeletal pain, risk for
falls was lower in those who used daily analgesic medica-
tion. Risk for recurrent falls and self-reported fractures
due to falls was also elevated in women with musculoskel-
etal pain, most consistently in women with widespread
pain.
CONCLUSIONS: Musculoskeletal pain, particularly wide-
spread pain, is a substantial risk factor for falls in older
women with disabilities. These findings add an important
dimension to our understanding of the multifactorial pro-
cesses leading to falls in older persons. J Am Geriatr Soc

Key words: pain; falls; osteoarthritis; fibromyalgia; aging;
musculoskeletal; women
alls are a major cause of disability, healthcare utiliza-
tion, and mortality in the older population. Fall-re-
lated deaths in older persons have been on the increase in
the past 15 years, and rates are highest in those aged 85
and older,
1
the fastest-growing segment of the older popu-
lation. An estimated 87% of fractures in adults aged 65
and older are due to falls.

In 1994, falls and their sequelae
in persons aged 65 and older in the United States cost an
estimated $20.2 billion.

Although many risk factors for
falls have been examined in several longitudinal studies,
4–6
musculoskeletal pain, a major contributor to disability in
older persons,
7–9
has rarely been evaluated as a fall hazard.
Osteoarthritis (OA), assessed by self-report, has been
implicated as a cause of falls in older persons,
5,6
possibly
related to postural instability and reduced muscle strength
in the lower extremities.
10,11
However, radiographic hip
OA in the Study of Osteoporotic Fractures was found to
be protective for falls.
12
The concordance between self-
reported arthritis and radiographic disease is poor, but the
concordance between self-reported arthritis and knee pain
is much higher,
13
lending credence to the notion that self-
reported arthritis is more an indication of pain symptoms
than confirmed disease. The relationship between pain
and falls is unknown and requires study. In general, the
