Risk of motor vehicle accidents is higher in people with sleep apnea
Treatment with CPAP leads to considerable reduction in motor vehicle accident risk
2015-03-10
(Press-News.org) DARIEN, IL - A new study finds that obstructive sleep apnea is associated with a significantly increased risk of motor vehicle accidents, and this risk is reduced when sleep apnea is treated effectively using continuous positive airway pressure (CPAP) therapy.
Results show that patients with sleep apnea were nearly 2.5 times more likely to be the driver in a motor vehicle accident, compared with a control group of other drivers in the general population. Further risk analysis found that severe excessive daytime sleepiness, a short sleep duration of 5 hours or less, and use of sleeping pills were independent predictors of increased crash risk in patients with sleep apnea. The study also found that the incidence of motor vehicle accidents was reduced by 70 percent among sleep apnea patients who used CPAP therapy for an average of at least 4 hours per night.
"This study provides very strong evidence that obstructive sleep apnea patients have an increased traffic accident risk and that this risk can be modified if CPAP treatment is used adequately," said principal investigator and senior author Dr. Ludger Grote, associate professor at the Center for Sleep and Vigilance Disorders at the Sahlgrenska Academy at the University of Gothenburg in Gothenburg, Sweden.
Study results are published in the March issue of the journal Sleep.
"Excessive daytime sleepiness is a common symptom of obstructive sleep apnea, which can cause you to awaken in the morning feeling tired and unrefreshed despite a full night of sleep," said American Academy of Sleep Medicine President Dr. Timothy Morgenthaler. "Effective identification and treatment of sleep apnea is essential to reduce avoidable, life-threatening accidents caused by drowsy driving."
The AASM reports that obstructive sleep apnea (OSA) is a common sleep disease afflicting at least 25 million adults in the U.S. Sleep apnea warning signs include snoring and choking, gasping or silent breathing pauses during sleep. The AASM and other partners in the National Healthy Sleep Awareness Project, which is funded by the Centers for Disease Control and Prevention, urge anyone with symptoms of sleep apnea to visit http://www.stopsnoringpledge.org to pledge to "Stop the Snore" by talking to a doctor.
Led by Grote and lead author Mahssa Karimi, PhD, the research team studied 1,478 sleep apnea patients with a mean age of 54 years. Seventy percent were men. Objective motor vehicle accident data were analyzed from the Swedish Traffic Accident Registry (STRADA). The control population of 635,786 driver's license holders included 21,118 individuals with a record of at least one motor vehicle accident during the study period. Sleep apnea patients were involved in 82 motor vehicle accidents while driving during the study period, including 56 accidents in the 5 years prior to diagnosis and 26 accidents in the 5 years after diagnosis. Objective CPAP adherence data were obtained from the device at follow-up visits.
The authors noted that the effect of OSA on motor vehicle accident frequency may be even higher in other countries. The AAA Foundation for Traffic Safety estimates that drowsy driving may cause 328,000 motor vehicle accidents and 6,400 fatal crashes on U.S. roads each year.

Many mammals -- and some birds -- escape the winter by hibernating for three to nine months. This period of dormancy permits species which would otherwise perish from the cold and scarce food to survive to see another spring. The Middle East, with temperate winters, was until recently considered an unlikely host for hibernating mammals.
New research published in Proceedings of the Royal Society of London by Tel Aviv University researchers is set to not only correct this fallacy but also change the very concept of hibernation. Prof. Noga Kronfeld-Schor, Chair of the Department ...

Natural forces have always caused the climate on Earth to fluctuate. Now researchers have found geological evidence that some of the same forces as today were at play 1.4 billion years ago.
Fluctuating climate is a hallmark of Earth, and the present greenhouse effect is by far the only force affecting today's climate. On a larger scale the Earth's climate is also strongly affected by how the Earth orbits around the sun; this is called orbital forcing of climate change. These changes happen over thousands of years and they bring ice ages and warming periods.
Now researchers ...

COLUMBUS, Ohio - New clinical-trial findings provide further evidence that combining chemotherapy with radiation therapy is the best treatment for people with a low-grade form of brain cancer.
The findings come from a phase II study co-led by a researcher at Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and researchers at the University of Maryland and at London Regional Cancer Program in Ontario, Canada.
The study shows that patients with low-grade gliomas and at high risk ...

Established ways of measuring carbon emissions can sometimes give misleading feedback on how national policies affect global emissions. In some cases, countries are even rewarded for policies that increase global emissions, and punished for policies that contribute to reducing them.
"We have developed a new method that provides policy makers with more useful information, in order to set national targets and evaluate their climate policies", says Astrid Kander, Professor in Economic History at Lund University, and lead author of the study, published in the latest issue ...

What inspires people to support conservation? As concerns grow about the sustainability of modern society, this question becomes more important. A new study by a team of researchers from Clemson University and Cornell University offers one simple answer: birdwatching and hunting.
Their survey of conservation activity among rural landowners in Upstate New York considered a range of possible predictors, such as gender, age, education, political ideology and beliefs about the environment. All other factors being equal, birdwatchers are about five times as likely, and hunters ...

A study of a recently discovered fossil published by LMU zoologists reveals the specimen to be the oldest known crab larva: The fossil is 150 million years old, but looks astonishingly modern.
To catch living crab larvae, all you have to do is trawl a plankton-net in the nearest bay or tidal pool. Finding fossilized crab larvae is rather more difficult - as witnessed by the fact that the specimen described in "Nature Communications" today by Ludwig-Maximilians-Universitaet (LMU) in Munich zoologists Joachim and Carolin Haug, and Joel Martin of the Natural History Museum ...

The increasing strength of winds over the Southern Ocean has extended its ability to absorb carbon dioxide, effectively delaying the impacts of global warming.
New research published in the Journal of Physical Research found the intensifying wind over that ocean increased the speed and energy of eddies and jets, which are responsible in large part for the movement of nutrients, heat and salt across the ocean basin.
The increased movement and overturning of these eddies and jets has accelerated the carbon cycle and driven more heat into the deep ocean.

Capping and regulating CEO payments, including performance bonuses, could help make companies more profitable in the long term, new research has found.
According to modeling by Dr Peter Cebon at the University of Melbourne in Australia and Dr Benjamin Hermalin from the University of California, Berkeley, reliance on performance bonuses - which are often $7-10 AUD million per year for top Australian CEOs - can lead executives to pursue poor strategies, including being too focused on short term gains.
The model also showed that if bonuses are restricted, CEOs and boards ...
