Most U.S. soldiers come home with sleep disturbance

The numbers are staggering for soldiers in the weeks after returning home from war. Researchers say 86 percent of them have some kind of sleep disturbance.

An abstract being presented at SLEEP 2010 shows the toll deployment takes American servicemen and women’s sleep.

Participants in the study were assessed the moment they stepped foot back on U.S. soil. The follow-up was 45 days later. Authors used a variety of tests to screen for sleep disturbances and physical and mental health problems.

Most of the soldiers in the study didn’t have post-traumatic stress or depression. Researchers found those with a history of sleep problems, physical illness or brain injury were more likely to report sleep disturbances.

Sleepless Nights for Army Wives

A new study examined how deployment affects the mental health of the wives of U.S. Army soldiers. The results were published yesterday in the New England Journal of Medicine.

The study involved 250,626 wives of active-duty U.S. Army soldiers. Their electronic medical records from 2003 to 2006 were analyzed.

Results were compared according to the deployment status of their husbands. Length of deployment also was considered. Deployments included both Operation Iraqi Freedom and Operation Enduring Freedom in Afghanistan.

Adjusted results show that the wives of deployed soldiers had more sleep problems than the wives of soldiers who were not deployed. They also had more cases of depression and anxiety.

They had 11.6 excess cases of sleep disorders per 1,000 wives when the deployment lasted up to 11 months. This rate increased to 23.5 excess cases when their husband was deployed for more than 11 months.

“This study confirms what many people have long suspected,” lead author Alyssa Mansfield, PhD, said in a news release. “It provides compelling evidence that Army spouses are feeling the impact of recent deployments to Iraq and Afghanistan. The result is more depression, more stress, more sleepless nights.”

The authors noted that current warfare in Iraq and Afghanistan differs greatly from other recent conflicts involving the U.S. Both operations have involved sustained ground combat. They also have been met by strong insurgent attacks.

As a result the wives of deployed soldiers may fear for the safety of their loved ones. At the same time they face the stress of maintaining a household and caring for children alone.

The authors also suggested that the results may underestimate the severity of the problem. In the military seeking care for mental health concerns may involve a stigma. So some spouses may avoid seeking care.

“The majority of active-duty soldiers are married, so we need to pay attention to the needs of their families,” said Mansfield.

Sleepy Soldiers: Proposal Recommends More Sleep for U.S. Combat Troops

Stars and Stripes reports that the U.S. Army Medical Command is proposing changes to current Army sleep guidelines.

The draft proposal recommends that U.S. soldiers in combat zones get seven to eight hours of sleep each night. Current guidelines suggest that soldiers get at least four hours of sleep each day when deployed.

The change would help prevent “performance degradation” on the battlefield. The guidelines state that sleep loss can have a critical effect on problem solving and decision making. It can result in delayed reaction times, lapses of attention and confused thinking.

The article cites two recent studies conducted at the Walter Reed Army Institute of Research. The first study was published in the journal Sleep in 2007. It shows that 53 hours of sleep deprivation can impair the ability to make some moral judgments.

The second study is in the current issue of Sleep. It shows that “banking sleep” before a period of sleep deprivation can reduce the effects of sleep loss on performance and alertness.

The study restricted the sleep of two groups to three hours in bed for seven nights. Prior to the sleep restriction, one group extended their nightly sleep to 10 hours in bed for one week. The other group maintained a typical nightly sleep time of about seven hours in bed during the week before sleep restriction.

The “extended sleep” group performed better during sleep restriction. They were better able to remain awake during the day. Their performance also rebounded faster after the period of restricted sleep.
