P018 Impact of academic, sports, and extracurricular activities on sleep patterns in early adolescents

Abstract Introduction Adolescents often report insufficient sleep and poor sleep quality, potentially due to busy schedules with academic tasks, sports, and extracurricular activities. This study investigated the impact of these activities on sleep onset, wake time and sleep duration in early adolescents. Methods Participants were 167 secondary school students in Melbourne, Australia (Mean age = 12.81±0.41 years, 56% female). During the school term, participants reported sleep-wake patterns over 2 weeks (sleep diaries). They also reported their weekly hours spent on academic, sports, and extracurricular activities outside of school, and the number of days they engaged in these activities before or after school (School and Sleep Habits Survey). Multiple linear regression analyses controlling for age, sex, ethnicity and COVID restrictions were conducted. Results Engaging in academic (Mean = 4.53 hours, Median = 3.00 hours), sports (Mean = 2.69 hours, Median = 2.00 hours), or extracurriculars activities (Mean = 1.02 hours, Median = 0.00 hours) weekly, whether in the morning or evening, was not independently or collectively associated with delayed bedtime, advanced wake times, or shortened sleep duration. However, more days spent engaging in evening sports during the week were associated with earlier bedtimes (p =.014). Conclusion More time spent on evening sports may be associated with earlier bedtime, but the study did not find associations between academic or other extracurricular activities and sleep during the school term. Further research is warranted to accurately quantify the types and intensity of these activities and their daily associations with sleep in adolescents.
