Researchers at University of Chicago studied 90 children who were referred to a sleep clinic. They evaluated those with breathing problems during sleep and 30 children who do not snore. All the children underwent standard overnight sleep tests. Urine samples were collected the next morning.
Researchers found that a number of the proteins were different in children with OSA.
Doctors hope such a test would alleviate the need for costly and inconvenient sleep studies in children who snore. They estimate that only about 20 to 30 percent of snoring children actually have OSA.
The study is reported in next week's issue of the American Journal of Respiratory and Critical Care Medicine.
