Objectives: The present study investigated the effectiveness of a school-based sleep education programme in improving key sleep behaviours, sleep knowledge, and sleep hygiene. Design and methods: A cross-sectional cluster-randomised controlled trial with two groups (Intervention and Control) and three assessment time points [baseline, immediately post intervention (6 weekspost baseline) and follow-up (18 weeks post baseline)] was employed. A total of 296 students (mean age = 12.2 ± 0.6 years; 59% female) from 12 schools in Adelaide, South Australia, were recruited, with 149 participants in the Intervention group and 147 in the Control group. The intervention consisted of four classroom lessons delivered at weekly intervals, followed by a group project on sleep topics, which students presented at a parental information evening. Sleep patterns were assessed objectively (actigraphy,n = 175) and subjectively (time-use recall, n = 251) at three time points. Sleep knowledge and sleep hygiene (n = 296) were also measured. Results: Generalised estimating equations were used to compare changes in the Intervention and Control groups. The programme increased time in bed by 10 min (p = 0.03) for the Intervention group relative to the Control group, due to a 10-min delay in wake time (p = 0.00). These changes were not sustained at follow-up. There was no impact on sleep knowledge or sleep hygiene. Conclusion: Investment in the sleep health of youth through sleep education is important but changes to sleep patterns are difficult to achieve. More intensive programmes, programmes with a different focus or programmes targeting different age groups may be more effective.
