Missing Link Between Mental Health Disorders and Diseases in Iraq War Refugees

Wayne State University School of Medicine researchers may have discovered why people exposed to war are at increased risk to develop chronic problems like heart disease years later. And the culprit that links the two is surprising.

 

Beginning in the mid-2000s, WSU researchers interviewed a random sample of 145 American immigrants who left Iraq before the 1991 Gulf War, and 205 who fled Iraq after the Gulf War began. All were residing in metropolitan Detroit at the time of the study. Study subjects were asked about socio-demographics, pre-migration trauma, how they rated their current health, physician-diagnosed and physician-treated obstructive sleep apnea, somatic disorders and psychosomatic disorders.

 

Those who left Iraq after the war began and suffered from mental disorders such as post-traumatic stress disorder (PTSD) and depression, and self-rated their physical health as worse than their actual health, were 43 times more likely than pre-Gulf War immigrants to report obstructive sleep apnea (30.2 percent versus 0.7 percent) and later develop major chronic health issues such as cardiovascular disease.

 

"I was surprised, but we had a specific theory we wanted to test. Changes in the stress system would contribute to sleep apnea. What happens? Maybe it's the stress that leads to this fractured sleep," said Bengt Arnetz, M.D., Ph.D., M.P.H., School of Medicine professor of occupational and environmental health, deputy director of the Institute of Environmental Health Sciences at Wayne State, and the study's principal investigator and first author. "No one had explored this possible link before, although basic research suggests it as plausible."

 

The obstructive sleep apnea and chronic disease link has been observed among many trauma-exposed populations, including refugees, Arnetz said.
