Sleep problems in a Down syndrome population.Arch Dis Child. 2009 Apr; 94(4):308-10.AD
OBJECTIVE
To determine the prevalence of sleep problems in children with Down syndrome.
DESIGN AND SETTING
A community prevalence study in a child population of 100 000 in England.
PARTICIPANTS
58 children with Down syndrome aged to 0.65-17.9 years (mean 8.6 years).
INTERVENTIONS
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.
