Introduction
This study provides a benchmark for the nationwide use of osteoporosis
screening, prevention and management strategies among Canadians aged 40 years and
older (40+) using data collected one year prior to the release of Osteoporosis Canada’s
latest (2010) clinical practice guidelines.
Methods
Data are from the 2009 Canadian Community Health Survey—Osteoporosis
Rapid Response Component. The study sample (n = 5704) was divided into four risk
subgroups: (1) osteoporosis diagnosis and major fracture; (2) osteoporosis diagnosis
only; (3) major fracture only; or (4) neither osteoporosis diagnosis nor major fracture.
We calculated descriptive statistics and performed multinomial multivariate logistic
regression analyses to examine factors independently associated with osteoporosis
screening, prevention and management strategies. Estimates were weighted to represent
the Canadian household population (40+) living in the 10 provinces.
Results
Approximately 10.1% of the population or 1.5 million Canadians 40+ reported
having been diagnosed with osteoporosis. The majority related taking vitamin D or calcium
supplements and having been prescribed osteoporosis medication(s), while less
than 40% reported regular physical activity. Among those without a reported osteoporosis
diagnosis, an estimated 6.7% or 1 million reported having had a major fracture, of
which one-third reported having had a bone density test and less than half reported
taking vitamin D supplements, calcium supplements or engaging in regular physical
activity. Major fracture history was not associated with bone density testing or osteoporosis
medication use.
Conclusion
A large proportion of Canadians at risk for osteoporosis—those with a
major fracture history—are not undergoing bone density testing nor are they engaging
in lifestyle approaches known to help maintain healthy bones. This study provides the
historical information required to evaluate whether the latest clinical practice guidelines
have had an impact on osteoporosis care in Canada.
