Odds, prevalence and predictors of sleep problems in school-age normal children.

The objectives of the study were to describe the prevalence, odds, and predictors of 36 paediatric sleep behaviours and describe their coexistence in a school-age normal population. The design was community-based questionnaire survey of sleep-wake patterns, sleep environment, and 36 sleep behaviours indicative of six sleep disorder-subscales using the Health-Behaviour Questionnaire. A caregivers' report of 3045 children aged 6-13 years in Belgium constituted the participants.

Pediatric sleep disorders: exploratory modulation of their relationships.

Study Objectives: This study explores relationships between clinically encountered sleep problems in children.

Design: The Sleep Disturbance Scale for Children (SDSC) (Bruni et al 1996), which screens 26 sleep problems and results in 6 sleep disorder-subscales, was used as core in a larger health-behavior questionnaire (HBQ).

Participants: Caregivers of 3045 6- to 12-year-olds filled out the HBQ.
