  Objective: To examine if sleep timing (combination of bedtime and wake up time) is associated with energy intake and physical activity/sedentary behaviour in obese adolescents.

We categorized participants as “late sleepers” (midpoint of sleep >3:30 a.m., n=13) and participants as “normal sleepers” (midpoint of sleep ≤ 2:30 a.m., n=13). Results: As expected, wake-up time and bedtime were different between sleep timing groups (p<.. View More»
