Overweight individuals are not just at greater risk of having sleep-disordered-breathing, they are also likely to suffer greater consequences, according to new research. According to the study , published in the American Journal of Respiratory and Critical Care Medicine, excess weight increased the severity of oxygen desaturation in the blood of individuals with SDB during and after apneas and hypopneas.

Stroke victims who have obstructive sleep apnea die sooner than stroke victims who do not have sleep apnea or who have central sleep apnea, according to Swedish researchers, who will present their findings at the American Thoracic Society’s 2008 International Conference in Toronto on Monday, May 19.

The researchers followed 132 stroke patients over 10 years. Twenty-three of those patients had obstructive sleep apnea; 28 of those patients had central sleep apnea. Those with an obstructive apnea-hypopnea index of 15 or greater were 76 percent more likely to die earlier. Those with a lower apnea-hypopnea index of 10 were also at greater risk of early death.

Research findings presented 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 an AHI between five and 15, who saw an increase of 0.22 kg/m2.

Work hassles hamper sleep

Common hassles at work are more likely than long hours, night shifts or job insecurity to follow workers home and interfere with their sleep.

That’s the conclusion of a University of Michigan study which was initially presented at the annual meeting of the Population Association of America.

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.
