Long-Term Study Links Chronic Insomnia to Increased Risk of Death

07.06.2010
Individuals with chronic insomnia have an elevated risk of death, according to a research abstract that will be presented Monday, June 7, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Results indicate that the adjusted hazard ratio for all-cause mortality was three times higher in people with chronic insomnia (HR = 3.0) than in people without insomnia. When examining individual subtypes of insomnia, the risk of death was elevated, regardless of which subtype people reported.

The risk of death in the four subtypes was two to three times higher in individuals with: chronic early-awakening insomnia (HR = 3.0), chronic sleep-maintenance insomnia who had difficulty getting back to sleep (HR = 3.0), chronic sleep-onset insomnia (HR = 2.4), and chronic sleep-maintenance insomnia who awakened repeatedly during the night (HR = 2.3).

"The most surprising result was the increased high risk for mortality among individuals with chronic insomnia versus those without insomnia, even after adjustment for all of the potential confounding variables" said lead author Laurel Finn, biostatistician at the University of Wisconsin-Madison. "The other important finding was the non-differentiation between subtypes of insomnia with respect to mortality risk."

The study involved 2,242 participants in the Wisconsin Sleep Cohort Study who completed two to three mailed surveys for years 1989, 1994 and 2000. Participants were considered to have chronic insomnia if they reported insomnia symptoms on at least two of the surveys. A social security death index search in May 2010 determined that 128 participants had died during a follow-up period of up to 19 years. Estimated mortality hazard ratios were adjusted for body mass index, age and sex, as well as for self-reported medical conditions such as chronic bronchitis, heart attack, stroke, hypertension, diabetes and depression.

Finn added that the results emphasize the need for physicians to provide effective treatments for insomnia even in the absence of co-morbid health problems.
"Insomnia is a burdensome symptom and has a negative impact on sleep quality that may lead people to seek treatment," said Finn. "The identification of insomnia as a mortality risk factor may have clinical implications and raise the priority level for insomnia treatment."

The study was supported by the National Heart, Lung, and Blood Institute; the National Institute on Aging; and the National Center for Research Resources of the National Institutes of Health.

A joint venture of the American Academy of Sleep Medicine and the Sleep Research Society, the annual SLEEP meeting brings together an international body of more than 5,000 leading clinicians and scientists in the fields of sleep medicine and sleep research. At SLEEP 2010 more than 1,100 research abstract presentations will showcase new findings that contribute to the understanding of sleep and the effective diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.

Media Note: Updates have been made to the study data since the publication of the abstract; current data are included in this press release and will be explained in the poster.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
