Objectives: It is known that children with sleep-disordered breathing (SDB) often have accompanying growth retardation and learning and behavior disabilities. However, these results are based mainly on studies of children from European and North American countries. The objective of this study was to investigate the school performance and behavior of Korean children with SDB. Methods: We enrolled 302 third-grade elementary students from an elementary school in Seoul. A survey was conducted, using information from the children's parents for the diagnosis of SDB. The children's height, weight, midterm examination scores, and behavioral disturbances were analyzed. Results: Overall, 299 parents returned the survey. Of the 299 students, 29 (9.7%) were considered to have SDB. They showed no difference from the control in terms of body mass index. The mean examination score was higher in the control group than in the SDB group. However, there was a statistical difference only in social science. The prevalences of students who were inattentive (58.6% versus 23.7%) and lacking in self-control (44.8% versus 14.1%) were significantly higher among students with SDB. Conclusions: SDB is not closely associated with poor school performance among Korean elementary students. However, behavioral disturbance is more frequent among the students with SDB than in those without.
