38 pc adults, 12 pc kids use complementary
and
alternative medicines in US
Washington:
A nation-wide survey commissioned by the US Government
has revealed that about 38 per cent of adults in the
country and 12 per cent of children use some form
of complementary and alternative medicine (CAM). CAM
is a group of diverse medical and health care systems,
practices, and products. It involves treatments with
herbal supplements, meditation, chiropractic and acupuncture
that are not generally considered to be part of conventional
medicine. The new findings attain significance as
they emerge from the first ever survey to include
questions on children's use of CAM.
The
research was carried out as part of the 2007 National
Health Interview Survey (NHIS), an annual study in
which tens of thousands of Americans are interviewed
about their health and illness-related experiences.
It included questions on 36 types of CAM therapies
commonly used in the US -10 types of provider-based
therapies, such as acupuncture and chiropractic, and
26 other therapies that do not require a provider,
such as herbal supplements and meditation. "The 2007
NHIS provides the most current, comprehensive, and
reliable source of information on Americans' use of
CAM," said Dr. Josephine P. Briggs, director of NCCAM.
"These statistics confirm that CAM practices are a
frequently used component of Americans' health care
regimens, and reinforce the need for rigorous research
to study the safety and effectiveness of these therapies.
The data also point out the need for patients and
health care providers to openly discuss CAM use to
ensure safe and coordinated care," she added.
The
2007 survey results, released in a National Health
Statistics Report by NCHS, are based on data from
more than 23,300 interviews with American adults,
and over 9,400 interviews with adults on behalf a
child in their household. Comparing the results of
surveys conducted in 2002 and 2007, the researchers
observed that overall use of CAM among adults had
remained relatively steady-36 percent in 2002 and
38 percent in 2007. The researchers, however, added
that there had been substantial variation in the use
of some specific CAM therapies like deep breathing,
meditation, massage therapy and yoga, which all showed
significant increases. They said that adults used
CAM most often to treat pain including back pain or
problems, neck pain or problems, joint pain or stiffness/other
joint condition, arthritis, and other musculoskeletal
conditions. But adult use of CAM therapies for head
or chest colds showed a marked decrease from 2002
to 2007.
It
was also found that overall use of CAM among children
was nearly 12 percent, or about 1 in 9 children. The
researchers said that children were five times more
likely to use CAM if a parent or other relative used
them. They also observed some similarities between
the characteristics of adult and child CAM users like
socio-economic status, geographic region, the number
of health conditions, the number of doctor visits
in the last 12 months, and delaying or not receiving
conventional care because of cost are all associated
with CAM use. Among children who used CAM in the past
12 months, CAM therapies were used most often for
back or neck pain, head or chest colds, anxiety or
stress, other musculoskeletal problems, and Attention
Deficit/Hyperactivity Disorder (ADD/ADHD). "The survey
results provide information on trends and a rich set
of data for investigating who in America is using
CAM, the practices they use, and why," said Dr. Richard
L. Nahin, acting director of NCCAM's Division of Extramural
Research and co-author of the National Health Statistics
Report. "Future analyses of these data may help explain
some of the observed variation in the use of individual
CAM therapies and provide greater insights into CAM
use patterns among Americans," he added.
