Back to sleep or not: the effect of the supine position on pediatric OSA: Sleeping position in children with OSA

“This study identified that preschool-aged children, whether nonsnoring controls or children with OSA, predominately sleep in the supine position, and OSA was more severe in the supine position. We suggest that to avoid the supine sleep position, positional therapy has the potential to ameliorate OSA severity, and the known cardiovascular consequences.”
