title: Epidemiologic study of sleep disorders in Kuwaiti adolescents.
abstract: A sample of 2,574 volunteer Kuwaiti boys (n = 1,309) and girls (n = 1,265) in secondary schools were recruited. Their ages ranged from 14 to 18 years. 13 items were used to assess prevalence of insomnia, hypersomnia, nightmares, sleepwalking, sleep terror, and narcolepsy. Participants were requested to respond according to the past month on a 5-point scale. The summation of responses in the last two options, i.e., "Much" and "Very much" was considered as the point prevalence rates. Girls had significantly higher mean ratings than boys on the following items: difficulty initiating sleep, fitful and disturbed sleep, waking up several times, nightmares, and sleep terror, while boys had significantly higher mean ratings on sleepwalking and "watching TV causes naps or sleep." The point prevalence on all the items for boys ranged from 4.6% to 35.2%, and that for girls ranged between 1.0% and 37.5%. One should keep in mind that the present sample was not a clinical one.
