Abstract

The weighted prevalence of sleeping ≤ 5 hours on weekdays among Chinese adolescents is 1.1%.

Students sleeping ≤ 5 hours on weekdays are more likely to misuse opioids (2.12 times), sedatives (2.00 times), and any prescription drugs (1.89 times) compared to those sleeping 7-9 hours.
Those with more than 9 hours of sleep on weekdays are also at increased risk for opioid and sedative misuse.
A U-shaped relationship exists between sleep duration and nonmedical use of prescription drugs (NMUPD).
Significant associations were found between weekday sleep duration and NMUPD among Chinese adolescents.
Academic performance may moderate the relationship between sleep duration and NMUPD.

Nonmedical use of prescription drug (NMUPD) among adolescents has increased substantially over the last 2 decades, and evidence suggests that sleep duration may impact upon drug use and academic performance. This study aimed to estimate the prevalence of sleep duration, NMUPD, and academic performance among Chinese adolescents, to test the independent associations of sleep duration with NMUPD, and to investigate whether these associations vary by academic performance. Data were from the 2015 School-based Chinese Adolescents Health Survey using a multi-stage, stratified-cluster, random-sampling method to collect information from 162,601 high school students [mean age (SD) =15.2 (1.9) years; 47.4% were male] from 42 cities in China. The weighted prevalence of sleeping ≤ 5 h/weekday was 1.1% (95% CI, 1.0-1.1%), and the weighted prevalence of sleeping > 9 h/weekday was 7.6% (95% CI 7.4-7.7%). After adjusting for significant covariates and academic performance, the results showed that compared with those with 7-9 h/weekday sleep duration, students reporting ≤5 h/weekday were more likely to misuse opioids (AOR = 2.12, 95% CI 1.73-2.59), sedatives (AOR = 2.00, 95% CI 1.65-2.42), and any prescription drug use (AOR = 1.89, 95% CI 1.60-2.23); students with>9 h/weekday sleep duration were also at a higher risk of opioids use, sedative use, and any prescription drug misuse; the U-shaped association of sleep duration with NMUPD was found. Moreover, there exist significant associations between weekday sleep duration and NMUPD among Chinese adolescents, and academic performance plays a moderating role in the aforementioned associations. The efforts to prevent NMUPD should be focused on adolescents who report abnormal sleep duration or poor academic performance.
