Sleep habits, sleep problems and subjective depth of sleep among 1413 schoolchildren aged 6.2‐10.9 y were examined via a questionnaire, answered by the child and parent together. Total sleep time was approximately 10.5 h, with no difference between the sexes. Of 887 children who reported that they were awoken at night, parents considered that 75% were superficial sleepers and 25% were deep sleepers. The prevalence of frequent insomnia, sleepwalking and daytime sleepiness was 13, 7 and 4%, respectively. Logistic regression analyses indicated that onset insomnia was associated with fear of sleeping alone, bone pains, hypnagogic myoclonias, rhythmic movement disorder, enuresis, nocturia, confusion when awoken at night, nightmares, bodily movements during sleep, interrupted sleep, daytime sleepiness and daytime headache or stomach ache. Somnambulism was associated with rhythmic movement disorder, somniloquy, spontaneous confused arousals, nocturia and confusion when awoken at night. Increased risk of daytime sleepiness was found among children with fear of sleeping alone, onset insomnia, rhythmic movement disorder, spontaneous confused arousals, snoring, confusion when awoken, nightmares, bodily movements during sleep and headache or stomach ache. Conclusion : The results support the notion that onset insomnia is a problem with a predominantly psychological and behavioural background, while sleepwalking is a disorder of arousal without major psychological implications. The mechanisms behind daytime sleepiness seem to be multifactorial.
