A study in the Aug. 1, 2010 issue of the journal Sleep suggests that regularly sleeping for more or less than seven hours per day is associated with an increased risk of cardiovascular disease. Results show that eight percent of the study population reported sleeping five hours per day or less including naps, and multivariable [...]
Dramatic weight loss may be an effective way to improve moderate to severe sleep apnea in obese men, scientists at the Swedish medical university, Karolinska Institute, report. Those with severe sleep apnea when the study began benefited most from weight loss.
“Our findings suggest that weight loss may be an effective treatment strategy for sleep apnea in obese men,” says Kari Johansson, one of the researchers involved in the study.
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.
Patients who suffer from both allergic rhinitis and obstructive sleep apnea may experience escalated symptoms of stress and fatigue.
In a paper presented at the 2009 American Academy of Otolaryngology — Head and Neck Surgery Foundation annual meeting, researchers told of results from 34 people who were diagnosed with obstructive sleep apnea.
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.
Babies born to obese mothers may have an increased risk of asthma, according to data from a new study to be presented at the American Thoracic Society’s 105th International Conference in San Diego.
“Obesity is not a neutral state; adipose tissue is an active producer of pro-inflammatory cytokines, while it also suppresses the action of anti-inflammatory cytokines,” said Jet Smit, Ph.D. “When you have an obese person, you are not just looking at a problem of excess fat, but a problem of systemic inflammation. This may affect the immunological and pulmonary development in the fetus and possibly result in a higher risk of asthma symptoms after birth.”
A new study shows both obesity and a large belly appear to increase the risk of developing restless legs syndrome (RLS), a common sleep disorder characterized by an irresistible urge to move and kick your legs.
The research was published in Neurology, the medical journal of the American Academy of Neurology. It is estimated that five-to-10 percent of adults in the United States have RLS and the disorder often has a substantial impact on sleep, daily activities, and quality of life.
Is obesity all in your head? New research suggests genes predispose people to obesity act in the brain and that some people may simply be hardwired to overeat.
An international team of researchers, co-led by the University of Michigan, found six new genes that help explain body mass index and obesity, and all but one of the genes are tied to the brain rather than to metabolic functions, such as fat storage and sugar metabolism.

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.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
