Social jetlag and sleep habits in children and adolescents: Associations with autonomy (bedtime setting and electronics curfew) and electronic media use before sleep.

For young people attending school, social jetlag (SJL) refers to discrepancy in sleep/wake timing between school days and weekends. This study investigated SJL in school-aged children and adolescents in England and whether this is associated with age, gender, and sleep habits including bedtimes and electronic media use. Students (school y 5-13; typical age 9-18 y) completed the 2021 OxWell Student Survey.

Insomnia symptoms in children and adolescents: screening for sleep problems with the two-item Sleep Condition Indicator (SCI-02).

Background: Sleep problems are common in young people. Yet brief screening measures to identify those most in need of an intervention are lacking. This study investigated the potential of the two-item Sleep Condition Indicator (SCI-02) for screening insomnia symptoms in children and adolescents.

Sleep in the time of COVID-19: findings from 17000 school-aged children and adolescents in the UK during the first national lockdown.

Study Objectives: Sleep is essential to young people's wellbeing, yet may be constricted by the adolescent delayed sleep phase coupled with school start times. COVID-19 restrictions caused major disruptions to everyday routines, including partial school closures. We set out to understand changes in students' self-reported sleep quality, and associations with mental wellbeing and interpersonal functioning, during these restrictions.

The Teensleep study: the effectiveness of a school-based sleep education programme at improving early adolescent sleep.

Objective: To evaluate the impact of a school-based sleep education programme on adolescent sleep and sleep knowledge.

Methods: This is the first outcome report on 'Teensleep': a novel, teacher-led programme, comprising ten lessons that can be delivered flexibly. Students in Year 10 ( = 1504; mean age = 14.

The challenges of adolescent sleep.

Sleep is vital for our physical, emotional and cognitive health. However, adolescents face many challenges where their sleep is concerned. This is reflected in their sleep patterns including the timing of their sleep and how much sleep they achieve on a regular basis: their sleep is characteristically delayed and short.

Challenges in implementing and assessing outcomes of school start time change in the UK: experience of the Oxford Teensleep study.

Objective: Later school start times for adolescents have been implemented in the US and associated benefits found, although no randomised controlled trials (RCT) have been undertaken. The objective of this study was to evaluate the impact of two school interventions in the UK, a delayed start time and a sleep education programme, on students' academic performance, sleep outcomes and health-related quality of life.

Methods: The study had an RCT design to enable an investigation into the differential effects of two interventions or a combination of both: schools were to delay their start time to 10:00am and/or provide a classroom-based sleep education programme.
