Short summary
High screen time (>6 hours/day) is associated with a 2.78x higher likelihood of trouble falling asleep and a 2.55x higher likelihood of waking during the night, compared to low screen time (<2 hours/day) in US adults (n=1674). Overall sedentary time, measured by accelerometer, showed no association with sleep outcomes.

Key points
- High screen time (>6h/day) is linked to increased difficulty falling asleep (OR=2.78) and nighttime awakenings (OR=2.55).
- Low screen time (<2h/day) served as the reference group for comparison.
- Overall sedentary time, measured by accelerometer, was not associated with any sleep outcomes.
- Study included 1674 US adults from the 2005-2006 National Health and Nutrition Examination Survey.

Abstract
OBJECTIVE: To examine associations of accelerometer-assessed sedentary time and self-reported screen time with sleep outcomes. METHODS: Cross-sectional study of 1674 adults from the 2005-2006 US National Health and Nutrition Examination Survey. Accelerometers were used to assess sedentary time. Screen time and sleep metrics were assessed via self-report. RESULTS: Accelerometer-assessed sedentary time was not associated with sleep outcomes. Compared to participants with the least screen time (<2h/ day), participants with the most screen time (>6h/day) were more likely to report trouble falling asleep (OR = 2.78, 95% CI: 1.21, 6.40) and wake during the night (OR = 2.55, 95% CI: 1.17, 5.52). CONCLUSIONS: With respect to sleep outcomes, context-specific sedentary behaviors may be more important than overall sedentary time.
