Study Population
Seventy, normal, healthy, white children and adolescents ranging in age from 1 to 15 years were included in the study. They were recruited haphazardly from schools and kindergartens and from families of hospital employees. Only children who were assessed as being normal subjects without SDB by clinical history were included. Children with the following history or findings were excluded from the study: snoring, labored breathing or chest retractions during sleep, sleep apneas, craniofacial
Results
Subjects age ranged from 1 to 15 years (mean ± SD, 7.9 ± 4.4 years). Thirty subjects (43%) were male. The age and sex distributions are shown in Figure 1.
Discussion
Although polysomnography is a common procedure in children, reference values are inadequate. Only one study4 designed to establish normal values in children has been reported. A comparison of the present study to the previous report is presented in Table 2. The present study provides additional information on normal polysomnographic values in children.
Our population included only white children. It has been recently suggested that certain ethnic populations such as African Americans may be at
