Characterise Sleep Patterns Across Asia

Sleep problems are common in adolescents. Studies have consistently demonstrated that sleep disturbances are prevalent, affecting up to 50% of this population. In this project, the investigators aim to map out sleep patterns, risk factors, and obstacles for sleep in adolescents, capturing the diversity of societal factors that shape the sleeping habits of adolescents. The investigators aim to recruit school-aged adolescents (aged 12-18 years old) in 12 countries across 15 research centres (N = 1000 per centre) to fill in the questionnaire covering sleep-wake patterns, sleep problems, mood, behavioral, daytime functioning and their attitude and perception towards sleep.
