There is an extremely high prevalence of sleep disturbances in U.S. soldiers returning from wartime deployment, according to a research abstract presented June 8, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Results indicate that 86 percent of participants had sleep disturbances upon return from deployment and 45 days later even though the majority of them had no signs of post-traumatic stress disorder or depression. Soldiers were more likely to have sleep disturbances if they had a personal history of sleep problems, symptoms of physical illness or mild traumatic brain injury.

"This is the first study to describe the prevalence of sleep disturbances at two different time points in soldiers returning from deployment without any apparent physical trauma from blasts or amputation," said principal investigator Major Betty Garner, PhD, a nurse scientist in the Nursing Research Office at Landstuhl Regional Medical Center in Landstuhl, Germany. "The most surprising finding from this small preliminary sample was the extremely high percentage of sleep disturbances in soldiers even 45 days after they returned from wartime deployment back to the United States -- the safe zone."
