14 per cent of Canadian Forces in Afghanistan had mental health problems

14 per cent of Canadian Forces in Afghanistan had mental health problems: study: 
The research included 30,500 personnel who deployed in support of the Afghan mission from October 2001 to the end of 2008, and used the medical records of a random sample of about 2,000 of those. The study population was made up of mostly men under the age of 40 in the regular force.
One of the report's authors, Mark Zamorski of the Forces's Directorate of Mental Health, said the risk of a mental health problem appeared to be greater among junior non-commissioned personnel than officers, but didn't elaborate on the reasons for that.
