Fitbit Sleep Measures in Children with and without Sleep Disordered Breathing

Sleep disordered breathing (SDB) is a spectrum of diseases ranging from primary snoring (PS), upper airway resistance syndrome (UARS), to obstructive sleep apnea (OSA). OSA constitutes the more severe end of the spectrum, while PS is the least severe and consists of nightly snoring without apnea, hypoxemia, or hypoventilation. Although PS does not characteristically demonstrate gas exchange abnormalities on polysomnography and is usually considered a more benign condition, it still may be associated with significant neurocognitive and behavioral issues, such as hyperactivity, inattentive behavior, aggression and poor school performance [1-4]. Emerging evidence suggests that children with PS may have increased sleep disruption, movement, and sleep fragmentation [5-8].
