Changes in the amount of sleep and daytime sleepiness: A follow-up study of schoolchildren from ages 10 to 15 years

Aim: This study examines the amount of sleep and daytime sleepiness, and how these change in a follow-up cohort study of school-aged children.

Methods: A total of 1351 schoolchildren (aged 10) and their parents were invited to participate in the study and were studied again at ages 12 and 15 years. A survey put forth by the Health Behaviour of Schoolchildren research network was used.

Results: The amount of sleep during weekdays dropped significantly from age 10 to 15. At weekends, the amount of sleep increased significantly. During weekdays, the proportion of children reporting having slept enough dropped from 71% at age 10 to 19% at age 15. Frequent daytime sleepiness occurred in 13% of children at age 10 and increased to 24% at the age of 15.

Conclusions: It is essential to promote adequate amount of sleep and prevent daytime sleepiness in children growing from age 10 to 15 years. Nurses and other health care professionals should systematically assess and promote healthy sleeping habits while caring for children between these ages.
