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

Area of Science:

• Pediatric Sleep Medicine
• Behavioral Sleep Science
• Public Health Research

Background:

• Sleep problems are common in children, but their prevalence and coexistence in the general population are not well understood.
• Understanding sleep behaviors and disorders in school-aged children is crucial for early identification and intervention.
• Existing research often focuses on clinical samples, leaving a gap in knowledge regarding community-based sleep patterns.

Purpose of the Study:

• To determine the prevalence, odds, and predictors of 36 specific pediatric sleep behaviors.
• To investigate the coexistence of these sleep behaviors and their association with sleep disorder subscales.
• To identify factors influencing sleep problems and disorders in a normal school-age population.

Main Methods:

• A community-based questionnaire survey involving caregivers of 3045 children aged 6-13 years in Belgium.
• Utilized the Health-Behaviour Questionnaire to assess sleep-wake patterns, sleep environment, and 36 sleep behaviors.
• Employed log-linear modeling and logit regression analysis to examine behavior coexistence and predictor effects.

Main Results:

• Significant differences in sleep-wake patterns were observed between weekdays and weekends.
• 'Tired when waking up,' 'repetitive limb movements,' 'going to bed reluctantly,' and 'sleep paralysis' were common sleep problems.
• Disorders of excessive somnolence (DES) were highly prevalent in this non-clinical sample, with significant coexistence among sleep problems.

Conclusions:

• Disorders of excessive somnolence (DES) are common in school-aged children, even in non-clinical settings.
• Sleep-onset latency and poor sleep environment (noise, inadequate darkness) predict increased odds of sleep problems.
• Enhanced sleep hygiene education for parents and children is advocated to address prevalent sleep issues.
