Summary

Our research question is: Are changes in sleep duration that occur naturally over school holidays associated with changes in blood pressure (BP) in sleep-deprived adolescents?

In this study, the investigators will take advantage of changes in sleep duration that occur during school holidays in adolescents who are sleep deprived (\>6 months' history of sleeping \<8 hours per night during school term). The investigators will monitor the changes in ambulatory BP and sleep duration over a period of 3 weeks which consist of a week at school, followed by a week of holiday when natural sleep extension takes place, and then another week of school after the holiday. Sleep-wake cycle will be recorded throughout the whole study period with actigraphy and sleep diary. Twenty-four hour ambulatory BP monitoring will be performed on the same weekday during each study week, when salivary cortisol will also be collected. The primary outcome measure is the difference in ambulatory BP parameters between school term and holiday. A control group without sleep deprivation (history of sleeping \>8 hours per night) will also be studied concurrently

It is hypothesized that changes in sleep duration are negatively associated with changes in BP. If this study confirms our hypothesis, sleep extension can be used as a relatively inexpensive and simple behavioural intervention in the management and prevention of blood pressure abnormalities. More importantly positive results from this project will provide background information on which government and local school policy can be based and altered for the betterment of our youths.
