Primary snoring in children impacts cardiovascular f...( WESTCHESTER Ill. Primary snoring in...),Health
WESTCHESTER, Ill. Primary snoring in children may have an impact on cardiovascular functioning equivalent to that of moderate obstructive sleep apnea (OSA), according to a research abstract that will be presented Wednesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Angela Jackman and colleagues at the University of Melbourne and Monash University, Melbourne, Victoria, Australia, focused on 40 children who were referred for clinical assessment of a sleep-related breathing disorder and matched controls. Overnight polysomnography was performed, and heart rate and heart rate variability data from the total sleep period and from periods of uninterrupted sleep were analyzed. The subjects were grouped by clinical diagnosis: primary snoring, mild OSA, moderate OSA, severe OSA, and controls.
According to the results, significant overall differences were found in heart rate over the total sleep period and during stable sleep, whereby heart rate was highest in severe OSA, followed by primary snoring, moderate OSA, mild OSA, and controls. In time domain analyses, heart rate variability was significantly lower in primary snoring than in controls.
Primary snoring in children has traditionally been considered benign, in part because some children grow out of the condition without intervention, said Jackman. Mounting evidence now suggests, however, that this condition can impact cognition, behavior, and academic performance. Furthermore, our current preliminary findings concur with emerging evidence that primary snoring in children may also impact heart function. To the best of our knowledge, ours is the first study to compare the effects of varying severities of sleep-related breathing disorders on cardiovascular control and to suggest that children with primary snoring may be just as affected as children with more severe sleep-related breathing disorders (such as obstr
