Forty percent of police officers in North America have sleep disorder symptoms, according to a survey of 5,000 officers across the U.S. and Canada.

Researchers found sleep apnea to be the most common disorder.

Like other sleep disorders, apnea is associated with poor health, poor performance, and even increased safety risks because of the nature of the officers' work.

The study's authors say their findings show the need for proper screening and treatment to improve overall performance.

The study is published in this week's Journal of the American Medical Association.
