Study is the first experiment to systematically examine the relationship of the duration of sleep dose to the recovery of neurobehavioral deficits from sustained sleep restriction.
A study in the Aug. 1 issue of the journal Sleep suggests that a dose of extra sleep on the weekend may be good medicine for adults who repeatedly stay up too late or wake up too early during the work week.
A small, portable device used for the home diagnosis of obstructive sleep apnea has been deemed very reliable, according to research findings presented at the 2008 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in Chicago, IL.
According to the study, Reliability of Holter Oximetry for Home Sleep Apnea Testing, authored by researchers with the New York Otolaryngology group, 120 patients over a four-month period used Holter oximeters for home sleep testing, registering a 97 percent data recovery rate during that period. Furthermore, patients reported an average comfort score of 2 (on a scale of 1 to 10, where 1 is the most comfortable).
Surgical interventions for many obese children suffering from obstructive sleep apnea may not cure the problem, according to recently released research findings.
Obese children are at increased risk for developing obstructive sleep apnea (OSA), a sleep disorder that is associated with a decreased quality of life as well as behavioral, neuro-cognitive, cardiovascular, metabolic, endocrine, and psychiatric complications.
Research engineers and sleep medicine specialists from two Michigan universities have joined technical and clinical hands to put innovative quantitative analysis, signal-processing technology and computer algorithms to work in the sleep lab. One of their recent findings is that a new approach to analyzing sleep fragmentation appears to distinguish fibromyalgia patients from healthy controls.
Joseph W. Burns, a research scientist and engineer at the Michigan Tech Research Institute (MTRI); Ronald D. Chervin, director of the University of Michigan’s Michael S. Aldrich Sleep Disorders Laboratory; and Leslie Crofford, director of the Center for the Advancement of Women’s Health at the University of Kentucky, report the results of their study in the August 2008 issue of the journal Sleep Medicine.
As the new school year approaches, the National Sleep Foundation (NSF) and Awake In America encourage parents and kids to put healthy sleep on the list of back-to-school necessities. NSF and Awake In America recommend gradually adjusting sleep schedules in order to be alert and energized as well as to assure optimal learning, participation and health.
“Kids tend to sleep and wake up later during the summer, making the transition to the school-year sleep schedule difficult,” explains Awake In America’s President, Michele Narcavage. “As tempting as it is to enjoy sleeping late in the final days of summer break, getting up earlier for school will be much easier if kids begin adjusting their sleep schedules now.”
A research abstract presented at Sleep 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS), finds a link between poor sleep and suicidal behavior among children and adolescents with depressive episodes.
The study, authored by Maria-Cecilia Lopes, MD, PhD, of Sao Paulo University in Brazil, focused on 303 individuals with pediatric bipolar disorder and pediatric unipolar disorder during depressive episodes. The presence of sleep complaints and suicidal behavior were detected by face-to-face interviews during depressive episodes.
Obstructive sleep apnea (OSA) in very young children may cause some of the adverse cardiovascular health consequences seen in older children and adults with the condition, according to Israeli-based researchers, who presented their findings this morning at the American Thoracic Society’s 2008 International Conference in Toronto.
A new study is the first attempt to quantify the strength of the cross-sectional relationships between duration of sleep and obesity in both children and adults. Cross-sectional studies from around the world show a consistent increased risk of obesity among short sleepers in children and adults, the study found.
Francesco P. Cappuccio, MD, of Warwick Medical School in the United Kingdom, and colleagues performed a systematic search of publications on the relationship between short sleep duration and obesity risk. Criteria for inclusion were: report of duration of sleep as exposure, body mass index (BMI) as continuous outcome and prevalence of obesity as categorical outcome, number of participants, age and gender.
A study published in the May 1, 2008 issue of the journal Sleep is the first attempt to quantify the strength of the cross-sectional relationships between duration of sleep and obesity in both children and adults. Cross-sectional studies from around the world show a consistent increased risk of obesity among short sleepers in children and adults, the study found.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
