A recent article at USA Today
reports that obesity may be what causes some truckers to doze while
driving. Last month, the medical review board of the Federal Motor
Carrier Safety Administration was scheduled to finalize recommendations about
truckers and obstructive sleep apnea (OSA), a condition in which people
constantly reawaken for lack of air, says Maggi Gunnels, the agency's
director of medical programs. The board may consider requiring
truckers who have obstructive sleep apnea to get treated before
People with OSA wake up frequently because the disorder causes their airways to partially close. The constant awakening -- once every minute or two in severe cases -– prevents restful sleep and makes them unusually drowsy during their waking periods. According to a blog at SheKnows.com, an estimated 7.5 million drivers nod off behind the wheel in any given month! In fact, statistics show 37% of all drivers admit that they have dozed off while driving.
"In the United States, approximately 5,600 people are killed annually in crashes involving commercial trucks," Pack said in an article at Consumer Affairs. "Falling asleep while driving is an important factor in serious crashes involving commercial vehicles, prompting the question, why?" asks Allan Pack, director of the Center for Sleep and Respiratory Neurobiology at the University of Pennsylvania and adviser to the medical review board, who claims that obesity is a major contributor to OSA.
As a response to these allegations, the medical review board of the
Federal Motor Carrier Safety Administration is expected to recommend
that commercial truckers be required to undergo a sleep study once they
reach a certain level of obesity. However, review board members were
split over what level of obesity should trigger the sleep study
Pack says multiple studies have shown that automobile drivers who have sleep apnea have two and a half times greater risk of being in a crash. "And the crashes you get into tend to be fairly severe," he says, though no studies have been done to specifically address the crash risk of commercial truck drivers who have sleep apnea.
Gunnels says federal regulators already can ground drivers they believe are susceptible to drowsiness; the changes, if implemented, would give them more authority.
"Individually, trucking companies are becoming more aware of this issue and are screening truck drivers, but there's also a role the federal government can and should play," says Dave Osiecki, vice president of safety, security and operations at the American Trucking Associations. The federal agency's guidelines on truckers and sleep apnea need an update based on improved science and the medical community's better understanding of the condition, says Osiecki.
