Background: Down syndrome (trisomy 21) is a genetic disorder caused by the presence of all or a portion of a third chromosome 21. OSA is one of the most common co- morbidities in people who have DS. There are lot of research happening to understand the correlation between the DS and OSA in children.
Objective: The main objective of this pilot study was to determine the sleep characteristics and daily life habits in a group of children with Down syndrome, as well as to find out the relation between sleep disturbances and daily life habit achievement when compared to normal children in relation to sleep pattern with age differences.
Methods: Totally 49 DS children were identified at different ages. We selected 3- 5 yrs 15 children, 5 - 8 yrs 8 children, 8 - 10 yrs 11 children, more than 10yrs we selected 15 children randomly. Normal children served as control and the normal children data was used only for comparison only.
Results: The bedtime resistance of the children with DS had symptoms of falling asleep in own bed. The sleep behaviour of the children with DS had earlier wake times and bedtimes, leading to significantly (**p < 0.01) more hours of sleep during nights, largely due to significantly earlier bedtimes. There was mild statistically significant (*p < 0.05) difference in the amount of sleep time compared to normal children. In night waking of the children with DS had difference when compared to normal children, leading to troubling in getting sleep during nights after the child wake up. The morning waking of the children with DS was identified that the child wakes up by own. It is also noted that the child is tired during day and some sleep during day time which is also significant (*p < 0.05).
Conclusion: The behaviour and growth of the children improve after successful treatment of obstructive sleep apnea syndrome. The understanding of the sleep fragmentation in children with DS may lead to more appropriate treatment, resulting in an improvement of their psychomotor development.
