Background: Available evidences seem to suggest increasing trend in sleep deficit among teenagers worldwide, and there is limited information on this among Nigerian teenagers. This study was carried out to determine the basic sleep schedule and sleep duration among schooling teenagers in Ilorin, Nigeria.
Methods: This is a descriptive cross‑sectional study conducted among 20 selected public secondary schools in Ilorin, Nigeria. A multistage sampling technique was used to randomly select participating schools.
Result: A total of 1033 students participated in the study; of these 47.3% were males and 51.7% females. Students mean age (standard deviation) was 15.3 ± 1.6 years with a range of 12–19 years. Majority (76.2%) of participants co‑share bed with at least one person and some (23.8%) slept alone in bed. The three leading reasons given for going to bed were: Tiredness ‑ 31.1%, completion of house assignment ‑ 20.5%, and parental directive ‑ 12.4%. 10% of teenagers do make regular phone calls at night and 5.5% surf internet and use computers at night. Regular habits of daytime sleepiness were reported by 8.2% of study participants. Students’ mean sleep duration during school days was 9.33 ± 2.29 h compared to 10.09 ± 1.32 h at weekend (P < 0.05). The duration of night time sleep was adequate (>9 h) in 41% of students; borderline (8–9 h) in 44.3% while 13.3% of the students had insufficient nighttime sleep duration (<8 h) P < 0.05.
Conclusion: A substantial number of students had borderline nighttime sleep duration and so had potentials to transit into the problematic insufficient range. To prevent this, there is a need to educate schooling teenagers on the dangers associated with prolonged sleep insufficiency.
