Childhood Obstructive Sleep Apnea (OSA) Assessment View Calculator Obstructive sleep apnea (OSA) is a common problem in children and is recognized as one cause of daytime attention and behavior problems. Unlike adults with OSA, who are often overweight, young children with OSA are usually not overweight, making children with OSA harder to recognize and diagnose. The main treatment for children with OSA is surgery to remove the enlarged tonsils and adenoids. Take this quick assessment to learn the signs of childhood OSA and help you determine if your child may have obstructive sleep apnea.
