The study objective was to find out the predictors which explain subjective daytime
sleepiness (SDS)in schoolchildren.The questionnaire study included data on the child's
sleeping habits,sleep disorders,daytime sleepiness,progress at school and TV/video
watching.The corresponding parental data was also gathered.Bivariate cross-tabulations
and multivariate log-linear modelling were used as statistical methods.The participants
were 518 schoolchildren (9 to 17 years),398 mothers and 345 fathers.SDS was reported
in 21%of the children.The children with SDS slept less on weekdays and went to bed later
on Saturday nights,reported a long sleep latency and more dreaming,night waking,
insomnia,sleeptalking and video watching than the children without SDS.Their parents had
more sleep disturbances than the parents of the alert children.This study shows that SDS
in schoolchildren can be caused by poor sleeping habits and frequent sleep disorders,but
that parental sleep problems may also have effect on the symptom.(Sleep and Hypnosis
