 According to a research abstract that will be presented on Thursday, June11, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, a link exists between the severity of obstructive sleep apnea (OSA) and weight gain.Results indicate that people with an apnea-hypopnea index (AHI), the average of the combined episodes of apnea and hypopnea that occur per hour of sleep, of over 15 had an increase in body mass index (BMI) of 0.52 kg/m2 compared to those with...

 There is a high probability of obstructive sleep apnea (OSA) in non-obese, middle-aged patients, according to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.Results confirmed that OSA in non-obese patients is most prevalent in middle-aged men with larger neck sizes. Fifty-four percent (2,906) of 5,426 non-obese patients were OSA positive, and most of them were middle age (57 percent)....

 A study in the June 1 issue of the journal SLEEP found that waist circumference and body mass index (BMI) are consistent, independent risk factors for all severity levels of sleep disordered breathing (SDB) in children, suggesting that as with adult SDB, metabolic factors are important risk factors for childhood SDB.Results indicate that BMI and waist circumference, but not neck circumference, were significant and strong predictors of SDB at all severity levels "“ primary snoring,...

Findings show that factors other than central sleep apnea may contribute to poor sleep quality in heart-failure patients A study in the Jan. 1 issue of the journal Sleep demonstrates that the frequent arousals from sleep that occur in heart failure patients with central sleep apnea (CSA) may reflect the presence of another underlying arousal disorder rather than being a defensive mechanism to terminate apneas. Principal investigator, Douglas Bradley, professor of medicine at the University of...

This study is the first to use polysomnography and sound measurements to demonstrate the relationship between snoring sounds and sleepiness A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine shows that objectively measured snoring intensity is correlated with subjective sleepiness independent of the apnea-hypopnea index (AHI) in patients with moderate to severe obstructive sleep apnea (OSA). Results indicate that the sound intensity of objectively measured snoring in...
