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.
According to a research abstract presented on June 8, 2009, at Sleep 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, race significantly influences the risk of obesity conferred by short sleep duration, with blacks having a greater risk than whites. Results indicate that short sleep was associated with obesity, with the adjusted [...]
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.”
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.
Indulging in high-calorie foods during the holidays resulting in weight gain, especially around the neck, may lead to more problems than facing yourself in the mirror after the new year, says a Bloomington, Indiana-based health care provider.
Many Americans put on pounds during November and December. That extra weight leads not only to New Year’s resolutions, but possibly significant impairment of their air passages during sleep, according to Dr. David Lawler.
Individuals with sleep-related breathing disorders appear to burn more calories when resting as their conditions become more severe, according to a report in Archives of Otolaryngology–Head & Neck Surgery.
Sleep-related breathing disorders include snoring, sleep apnea, and other conditions in which airways are partially or completely obstructed during sleep. “Obesity is a major risk factor for the development of sleep-disordered breathing, and changes in body weight are associated with changes in sleep-disordered breathing severity,” the authors wrote.
Children and teens who get less sleep, especially those who spend less time in rapid eye movement (REM) sleep, may be more likely to be overweight, according to a report in the Archives of General Psychiatry.
The obesity rate has more than tripled among children six-to-11 years in the past 30 years, and approximately 17 percent of U.S. adolescents are now overweight or obese, according to background information in the article.
Tributyltin, a ubiquitous pollutant that has a potent effect on gene activity, could be promoting obesity, according to an article in the December issue of BioScience. The chemical is used in antifouling paints for boats, as a wood and textile preservative, and as a pesticide on high-value food crops, among many other applications.
Affecting sensitive receptors in the cells of animals, from water fleas to humans, tributyltin can, at very low concentrations — a thousand times lower than pollutants that are known to interfere with sexual development of wildlife species.

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.
