title: Sleep problems in a Down syndrome population.
abstract: OBJECTIVE
  To determine the prevalence of sleep problems in children with Down syndrome.
  
  
  METHODS
  A community prevalence study in a child population of 100 000 in England.
  
  
  METHODS
  58 children with Down syndrome aged to 0.65-17.9 years (mean 8.6 years).
  
  
  METHODS
  Child Sleep Habits Questionnaire.
  
  
  RESULTS
  Compared to published data for typically developing populations, children with Down syndrome were reported to have significantly greater bedtime resistance, sleep anxiety, night waking, parasomnias, sleep disordered breathing and day-time sleepiness. Amongst children 4 years and older, 66% rarely fell asleep in their own beds, 55% were always restless during sleep and 40% usually woke at least once during the night. Importantly, 78% seemed tired during the day at least 2 days per week, suggesting inadequate sleep.
  
  
  CONCLUSIONS
  Parents report universal sleep problems in school aged children with Down syndrome. Paediatricians should routinely enquire about sleep behaviour in these children.
