Association between Information and Communication Technology Usage and the Quality of Sleep among School-Aged Children during a School Week

الملخص EN

Objective.

To determine the association between intensity of information and communication technology (ICT) usage and quality of sleep in school-aged children during a school week.

Methods.

In all 61 subjects, 10–14 years of age, a quasiexperimental laboratory study where criterions for inclusion were absence of prior medical condition and duration of ICT use.

A portable device (Holter monitor) was used to measure heart rate variability (HRV) over a 24-hour period, while activity diary was used to record in 15-minute intervals ICT use and sleep and wake up time.

Low and high ICT user groups were formed according to their intensity of ICT use.

Statistical analysis was done with two independent samples tests and factorial ANCOVA.

Results.

The higher ICT users showed a lower sleep time standard deviation of normal to normal interval (SDNN) measures in comparison to the low ICT users.

Conclusion.

The intensive ICT use was associated with poorer quality of sleep indicated by physiological measures among children and adolescents.

Knowing the crucial role of healthy sleep in this age, the results are reason for concern.
