Age Plays a Major Role in the Increase of Respiratory Disturbances During Sleep
February 08, 2008 at 4:33 PM
Senior Health News
An increase in the prevalence of sleep apnea syndrome with age has been well documented. This study focused on breathing irregularities during sleep in 163 people who are currently completely healthy, as assessed by passing numerous physical and clinical health tests. The results showed that, in this group of currently completely healthy individuals, irregularities in breathing during sleep are remarkably common, particularly in older individuals. For example, only around five percent of currently healthy subjects under 50 years of age had a respiratory disturbance index (RDI) of more than 15 events per hour. This degree of sleep-disordered breathing is considered to be clinically significant by many physicians. In contrast, about half of currently healthy subjects over 65 years of age had an RDI of more than 15 events per hour. Respiratory disturbances, therefore, increase dramatically with age even in healthy individuals without symptoms or signs of obstructive sleep apnea syndrome.
“There are still discussions among clinicians regarding the clinical significance of the different degrees of sleep disordered breathing. Also, there is discussion concerning the best criteria for defining breathing abnormalities, which can range from completely obstructed breath (i.e., choking - leading to reduced oxygen supply and life-saving arousals) to loud snoring that may, or may not, lead to reduced oxygen supply and arousal from sleep,” said Steven A. Shea, PhD, of Brigham & Women’s Hospital in Boston, Mass., senior author of the study. “In addition, there are few long-term studies of clinical outcome in patients with sleep apnea, and the criteria and the measuring techniques have evolved substantially over recent years. Thus, we do not yet know the clinical relevance of these new findings.”
