      Although the psychomotor vigilance task (PVT) is commonly used in adult sleep research, normative data for PVT performance in children have not been published and performance in children with sleep disordered breathing (SDB) has not been explored. This report describes PVT performance among children participating in the Tucson Children's Assessment of Sleep Apnea (TuCASA). A community-based sample of 360 Caucasian and Hispanic children completed a standard PVT trial. Participants were 48% female and 36% Hispanic; mean age was 8.9 years. Children with respiratory disturbance index (RDI) >1 event/hour and those with parent-reported sleep problems were excluded from the normative analysis. Among normal sleepers, performance on several measures improved with increasing age and differed between boys and girls. No ethnic differences were detected. Among children with SDB, no differences in performance were identified. Age and gender differences in PVT performance must be considered when the PVT is utilized in pediatric populations.
