Treatment Of Sleep Apnea In The Young Needs To Be More Aggressive HERSHEY, PA -- January 5, 1997 -- Researchers have found that the most severe cases of sleep apnea occur in the young (people under 45) and should be treated more aggressively once it is diagnosed so that problems like hypertension and other cardiovascular problems can be reduced. "This study shows we need to reduce the threshold for treatment in the young and increase this threshold in elderly patients. Even mild cases of sleep apnea need to be treated more aggressively in the young," said Edward Bixler, Ph.D., professor of psychiatry at Penn State's College of Medicine. "Sleep apnea has been linked with hypertension and may also contribute to other severe cardiovascular problems. We need to really focus on early treatment." Bixler also states that these new findings about the young were not previously discovered because most studies in the past focused only on middle or older age groups. This study included subjects ranging from 20 to 100 years old. This is the largest study ever on sleep apnea in men and took five years to complete. It was sponsored by the National Institutes of Health (NIH). Bixler's research team interviewed a random sample of 4,364 men by phone and eventually brought a subgroup of 741 for further study into the sleep laboratory at The Milton S. Hershey Medical Center of the Penn State Geisinger Health System. This subgroup was chosen based upon the presence of risk factors like snoring, daytime sleepiness, obesity and hypertension. "We used several criteria to see if the patient had sleep apnea including brain wave patterns, eye movements, muscle tone, breathing patterns and oxygen levels. We found 3.3 percent of the group had sleep apnea," Bixler said. Sleep apnea is when a person stops breathing for at least 10 seconds, 10 or more times during an hour of sleep. The most common form of sleep apnea is obstructive sleep apnea. This is when a person is trying to breathe but the airway is obstructed, usually by the soft palate. This causes oxygen levels in the body to drop. Over time this causes severe strain on the heart and the blood pressure. Bixler's paper is published in this month’s issue of the American Journal of Respiratory and Critical Care Medicine. Bixler states that when sleep apnea is diagnosed later in life, it can often be attributed to aging. His studies have found that the problem gets worse until about age 55 and then seems to level off. "The first line of defence for less severe cases is weight loss. We also advise people to avoid alcohol -- it makes the problem worse,” he said. “For more severe cases we recommend CPAP (continuous positive airway pressure). Wearing a mask that forces air into the lungs during sleep prevents apnea. It works about 95 percent of the time. However, compliance is a major problem.” Bixler said the problem is worse in males, but it also occurs in females. He is currently working on a five-year study on women and sleep apnea.
