Guardian - A major study of bike helmet use around the world from more than 64,000 cyclists has found helmets reduce the risks of a serious head injury by nearly 70%.
The study also found neck injuries are not associated with helmet use and cyclists who wear helmets reduce their chance of a fatal head injury by 65%.
The compulsory wearing of bike helmets in Australia has long been a source of frustration for some cyclists, who argue it reduces participation rates. Previous studies have indicated helmet use encourages risk-taking behavior or does not reduce serious injury to the brain. Should bike helmets be compulsory?
But a comprehensive review by Australian statisticians Jake Olivier and Prudence Creighton from the University of New South Wales that drew together data from more than 40 separate studies found helmet use was associated with dramatically reduced odds of head injuries.
