<There have been a number of studies on the incidence and severity of
back pain in the developed world.

Incidence of back pain.
64% of adult Canadians reported back pain in the last year. The
incidence of back pain did not significantly vary across regional or
demographic groups. Of those that had not experienced back pain in the
last year, 44% had experienced pain at some time.
Of those that had experienced pain, 45% had experienced pain between
one and two years ago. 25% had experienced pain three to five years
ago and 27% more than five years ago.
In the past two years, 71% of adult Canadians had experienced pain. 

Duration of back pain.
A few hours/less than 1 day ? 22%
1 to 2 days ? 20%
More than 2 days/less than 1 week ? 12%
1 week ? 7%
More than 1 week/less than 1 month ? 8%
1 month ? 2%
More than 1 month/less than 6 months ? 6%
6 months to less than 1 year ? 2%
1 to 2 years ? 3%
Continuous ? 16%
Don?t know/na ? 1%

Severity of back pain
Mild ? 30%
Moderate ? 48%
Severe ? 21%
Don?t know ? 1%

This study also looks at the causes of back pain and the number of
working days lost.

United States.

US 2002 survey.
According to a survey sponsored by the American Academy of Physical
Medicine and Rehabilitation (AAPM&R), 54% of Americans have back pain.

56% report that the back pain interferes with their daily activities,
such as work, schools or leisure activities.

75-84% of all people will experience some form of back pain during
their lifetime. Approximately 1% of the United States population is
chronically disabled due to back pain and 1% is temporarily disabled.

American Academy of Orthopaedic Surgeons, Rosemont, IL, 1999. 

According to a survey sponsored by Stanford University Medical Center,
ABC News and USA Today, 25% of respondents suffer from back pain.
1,204 people were surveyed.

European Commission study
53% of the referred Norwegian population reported lower back pain
during the previous year. (Natvig B, Nessioy I, Bruusgaard D, Rutle O.
Musculoskeletal symptoms in a local community. Eur J Gen Pr 1995;

Between 58% and 84% of people have ever suffered back pain (Dionne CE.
Low Back Pain. In: Crombie IK, Croft P, Linton S, Le Resche L, Von
Korff M. editors. Epidemiology of pain. Seattle: IASP Press 1999:

The 2005 Pain Survey carried out by the British Pain Society,
questioned 975 people.
The survey found that 27% were suffering back pain. Of those
experiencing pain on a daily basis, 32% said it was due to back pain.
Media notes.

Northern Ireland 
This 2001 study by The Northern Ireland Statistics and Research Agency
(NISRA) focused on back pain.
Respondents were asked if they had ever consulted a doctor regarding back pain.
Overall, 39% of men and 42% of women had consulted a doctor regarding back pain.
Respondents from a manual occupational background were more likely to
have consulted a doctor regarding back pain (44%) than those from a
non-manual occupational background (40%).
Approximately a fifth (21%) of respondents had experienced severe back
pain in the previous 12 months. Women were more likely than men to
have reported severe back pain (22% and 18% respectively).

This study shows back pain by age. 
25 to 34 ? 12%
35 to 44 ? 16%
45 to 54 ? 17%
55 to 84 ? 18%
65 to 74 ? 15%
over 75 ? 15%

Thanks v-much. Can you please include some additional information to
round things off as it?s just a bit thin. What about other English
speaking countries in the developed world such as: Australia, New
Zealand, South Africa?

<This study reviews the literature describing lower back pain point
prevalence in the developed world.

Point prevalence
North America ? 6.8%
Sweden ? 12%
Denmark ? 13.7%
United Kingdom ? 14%
Belgium ? 33%
Canada ? 28.4%
Australia ? 25.5%

(Source: The epidemiology of low back pain in primary care. Peter M
Kent and Jennifer L Keating.)

According to this article most international studies of adult back pain report a
point prevalence of 15?30%, a 1-month prevalence of 19?43%, and a lifetime
prevalence of 60?70%.
(Source: Nachemson AL, Waddell G, Norlund AL, Epidemiology of neck and
low back pain. In:Nachemson AL, Jonsson E. (eds). Neck and back pain:

diagnosis and treatment. Philadelphia: Lippincott, Williams and
Wilkins; 2000, p165?88)

This study gives lower back pain point prevalence rates for Denmark,
UK, USA, Canada and Belgium depicted as a graph (see figure 2 below).
(Source: The Prevalence of Low Back Pain in Adults: A Methodological
Review of the Literature. Patricia L Loney and Paul W Stratford.)
Figure 2.
This survey randomly sampled 3000 Australian adults selected from the
Electoral Roll.
Summary of results.
Sample point prevalence ? 25.6%
12 month prevalence ? 67.6%
Lifetime prevalence ? 79.2%

In the previous 6 month period, 42.6% has experienced low-intensity
pain and low disability from it. 10.9% had experienced high intensity
pain and low diability and 10.5% had high-disability.
(Source: Low back pain in Australian adults: prevalence and associated
disability. Walker BF, Muller R, Grant WD. J Manipulative Physiol
Ther. 2004 May; 27(4):238-44.)

South Africa
According to this report, in adults the life time prevalence of lower
back pain is 70 to 80% in adults. The study found a lifetime
prevalence of 52.6% , one year prevalence of 50% and point prevalence
of 14.7% in adolescents.

New Zealand.
This study looks at prevalence of lower back pain in nurses in
Auckland. It found lifetime prevalence of back pain was 74.4%. The
lifetime prevalence of nursing-related back pain was 62.3%; the annual
prevalence was 36.8%; and the point prevalence was 11.6%. (Source:
Prevalence of back pain among nurses. Coggan C, Norton R, Roberts I,
Hope V. N Z Med J. 1994 Aug 10;107(983):306-8.)

This study found that 1-year period prevalence of low back pain was
very similar to that for the lifetime prevalence; both started at 7%
for the 12-year-old individuals and reached 56% and 67%  respectively,
for the 41-year-old individuals.
