CUHK Establishes Asia-Pacific First Dedicated
Centre for
Osteoporosis Care and Control
-
With substantial research findings and the strongest team in Asia for
the study of osteoporosis, The Chinese University of Hong Kong sets up
the Asia Pacific first specialised centre for osteoporosis care and control,
dedicated to the prevention, treatment and research of the disease.
The major purpose of the centre is to prevent this silent epidemic in this
millennium for spreading.
The Hong Kong Jockey Club Charities Trust has generously donated $41
million for the establishment of the Jockey Club Centre for Osteoporosis
Care and Control to promote bone health and better quality of life for
osteoporosis patients.
Everyday in Hong Kong, ten elderly subjects fracture their hips.
Osteoporosis is among the top 5 conditions in causing disability and prolonged
hospital stay for elderly. The total health care cost for osteoporosis
is projected to reach $1,000 million by 2010. Besides, osteoporosis
makes the life of the elderly very miserable. The only cost-effective
approach to this problem is primary prevention and treatment of high risk
patients.
The mission of the Centre is “Towards healthier bone for all, and an
improved quality of life for osteoporosis sufferers”. This is achieved
through four main programmes of the Centre: screening and treatment, rehabilitation
and patient support, primary prevention and health education, and training
for medical and health professionals.
The Osteoporosis Research Programme of the Chinese University has conducted
extensive research into the epidemiology, etiology, treatment and prevention
of osteoporosis. With the establishment of the Centre, these research
findings can be put into practice and further research will be enhanced.
The research projects at the Chinese University include:
Searching for osteoporosis genes
Genetic mapping for osteoporosis has been carried out in a large sample
of men and women. Genes for osteoporosis are different between Caucasian
and Chinese; and between men and women. Based on the existing findings,
genome studies would be performed.

Searching for the best drugs for osteoporosis
Large-scale randomised controlled clinical trials have been conducted
in search for the best drugs for osteoporosis. The drug alendronate
has been found to be well-tolerated by Chinese. A dosage of 10mg
increased bone mineral density by 5% per year. Long-term use will
reduce the rate of fracture by 50%. Hormonal replacement therapy
had similar effects in postmenopausal women. Calcitonin was found
to be associated with significant analgesic effects in patients with vertebral
fracture.
Searching for the causes of osteoporosis in Asian populations
The incidence of hip fracture increased by 200% in the last 20 years
in Hong Kong. Large scale epidemiological studies in the Asian-Pacific
region showed that the following lifestyle factors may cause osteoporosis:
a low calcium diet, a lack of physical activity, cigarette smoking and
alcoholism. The increasing use of oral and inhaled steroid had been
found to be a major cause of osteoporosis in studies of our patients.
It is recommended that Hong Kong citizens maintain a dietary intake of
800mg of calcium in a day, perform 3 times of loading bearing activities
(of 30 minutes duration) each week, and avoid cigarette smoking and alcoholism.
Patients on steroid therapy must be put on medications for osteoporosis.
The establishment of the Centre also received strong support from the
International Osteoporosis Foundation and the World Health Organisation.
