Time for bed: Bad sleep habits start early in school-age children
Bad sleep habits in children begin earlier than many experts assume. That鈥檚 the takeaway from a new study led by 平特五不中 researchers. The findings suggest that official sleep guidelines for young school children should be revisited 鈥� and that parents ought to maintain firm bedtime rules throughout children鈥檚 primary-school years.
The researchers studied the sleep patterns of children aged six to 11 years old, and found that those aged 8-11 increasingly showed the unhealthy patterns usually associated with adolescence: delayed bedtimes, inconsistent schedules, and sleep deprivation. Such patterns have been shown to impair children鈥檚 physical and mental health, as well as academic performance.
鈥淥ur findings contradict the prevailing assumption that sleep patterns remain largely unchanged during the school-age period, from six to 13 years old,鈥� says Reut Gruber, an associate professor in 平特五不中鈥檚 Department of Psychiatry and lead author of the study.
A total of 144 Montreal-area children participated in the study, which tracked their sleep during the academic year. Participants were divided into three age groups: 6-7 years; 8-9 years; and 10-11 years. Each participant鈥檚 sleep pattern was assessed in the home environment for seven nights using a miniature actigraph, a wristwatch-like device used to evaluate sleep by measuring movement.
Increasing and significant delays in sleep start time, shorter sleep durations, and larger night-to-night variation in sleep听 were found in each age group compared to the younger one (10 - 11> 8 - 9> 6-7 year olds).
The device measurements indicated that only 17% of children aged 6-7 got the recommended amount of actual sleep 鈥� and that proportion dropped to just 2.5% for those aged 10-11.
The findings, to be published in the journal Sleep Medicine, 鈥渉ighlight the importance of boundaries related to bed-time that parents should consider setting for their children even as they get older and more independent,鈥� says Gruber, who also serves as Director of the Attention, Behavior and Sleep Lab at Montreal鈥檚 Douglas Mental Health University Institute and the Canadian Sleep Society (CSS) Officer - Media & Advocacy; CSS听Pediatric Sleep Interest Group.
鈥淲e recommend that parents of children of all ages ensure their children:
- Get sufficient amount of good quality sleep
- Go to bed at the same time every night
- Wake up at the same time every morning
- Learn to appreciate the importance of sleep to their health, mood and academic success
- Get help if unable to fall asleep, stay asleep, get sufficient sleep, or if they do not appear well-rested in the morning.鈥�
鈥淎n Actigraphic Study of the Sleep Patterns of Younger and Older School-Age Children,鈥� Reut Gruber, et al, will be published in Sleep Medicine.
