Sleep and physical health during childhood

Furthermore, important links between sleep and a variety physical health outcomes during childhood have been recently examine.

Boto and colleagues (2012) investigated the relationship between sleep deprivation and accidental fall risk among children aged 1 to 14 years. Through the analysis of questionnaire data, it was found that an absence of naps and children’s previous week’s sleep pattern was associated with increased risk for accidental falls, after controlling for potentially confounding variables (i.e., age, gender, summer holidays, parent education and occupation). Overall, the findings provide evidence that reduced sleep duration increases the risk of accidental child injuries, and highlight the protective effect of naps for children.
Kim, C. W., Choi, M. K., Im, H. J., Kim, O. H.,Lee, H. J.,Song, J.,Kang, J. H.,& Park, K. H. (2012). Weekend catch-up sleep is associated with decreased risk of being overweight among fifth-grade students with short sleep duration, Journal of Sleep Research, 21, 546-551.
Kim and colleagues (2012) examined the association between weekend catch-up sleep and overweight status among 936 school children between (aged10 to 11 years). It was found that increased catch-up sleep during the week-end, is associated with a decreased likelihood of being overweight among children. There was also an interaction between sleep duration during the school week, and week-end catch up sleep, in relation to childhood overweight, whereby the effect of weekend catch up sleep on overweight was stronger for those that slept less during the school week.

The study was carried out to examine the relationships between objective and subjective sleep parameters and glucose regulation among youth with Type 1 diabetes. Participants with a Total AHI of greater than or equal to 1.5 had higher glucose levels. Moreover, children’s sleepiness and poor sleep habits were associated with depressive mood, as well as poorer academic outcomes, and quality of life. Associations between reduced slow wave sleep and higher glucose levels (hemoglobin A1C), poorer quality of life, and sleepiness were also noted. Furthermore, more time spent in stage N2 sleep was related to higher glucose levels, poorer sleep quality and sleepiness, as well as poorer emotional and behavioural and academic outcomes. The authors recommend that sleep be routinely assessed as a component of Type 1 diabetes management among youth.
