The research, to be published August 4 in the online edition of the Canadian Medical Association Journal (CMAJ), has found that approximately 25 per cent of men and women who develop hip fractures and 16 per cent of people who develop spine factures will die over a five-year period.
The national study was led by George Ioannidis, a health research methodologist in the Michael G. DeGroote School of Medicine, in collaboration with scientists from the schools of medicine and nursing at McMaster, as well as several universities across Canada.
Using data from the Canadian Multicentre Osteoporosis Study, the researchers examined the relationship between new fractures and mortality over a 5-year period in more than 7,750 Canadians aged 50 years and older. The study, looking at various types of fractures reported by participants, differed from previous research in that the study group was representative of the general population.
"Hip fractures may have long-lasting effects that result in eventual death by signalling or actually inducing a progressive decline in health," said Ioannidis. "Our results also showed that vertebral fracture was an independent predictor of death."
In addition, the researchers discovered that all types of bone breaks were more common among women than men, with the exception of rib fractures. They also determined that fractures were associated with other negative consequences such as increased pain, immobility and reduced health-related quality of life.
"People should be aware that fractures are a serious problem in osteoporosis," Ioannidis said. "They do not just reduce health-related quality of life, they actually cause death. So hip and spinal fractures need be taken very seriously, and prevention should be paramount in treating patients with osteoporosis."
The study found factors such as smoking, physical activity and the presence of other diseases increased the risk of death, but so did lower educational levels.
The authors concluded that interventions must be introduced to reduce the likelihood of fractures. These could include osteoporosis medications, fall prevention strategies, hip protectors and enhanced rehabilitation after fracture to improve mobility and strength.
The study was funded by the Canadian Institutes of Health Research.
Osteoporosis Canada reports that there are approximately 27,000 hip fractures per year in Canada. Data on spinal fractures is limited, but is estimated that more than 65 per cent of vertebral fractures go undetected. The annual cost of treating osteoporotic fractures is over $1.3 billion.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
