Abstract

Purpose

This study aimed to determine the unique utility of poor sleep health in predicting the onset of substance use in adolescents.

Methods

Middle school students (N = 829, mean (M)_age = 12.6 years, 52% female, 73% white) who participated in an ongoing prospective study of alcohol onset and progression completed a set of Web-based health behavior surveys over a 4-year period, with recruitment beginning in 2009. Surveys included assessments of alcohol, cigarette, and marijuana use as well as sleep duration, bedtime delay (from weekdays to weekends), and daytime sleepiness. Data were analyzed using discrete-time Cox Proportional hazard's regression.

Results

Controlling for participant age at sleep assessment, gender, and internalizing and externalizing behaviors, shorter sleep duration and greater daytime sleepiness in year 1 were associated with increased odds of having had a full drink of alcohol, having engaged in heavy episodic drinking, and having experienced alcohol-related consequences by year 4. Shorter sleep duration was also associated with increased odds of marijuana use by year 4. No sleep parameter was uniquely associated with increased odds of cigarette use (first puff or first full cigarette). Effects were evident for both males and females. Age at sleep assessment did not moderate effects.

Conclusions

Sleep health is a prospective predictor of the onset of alcohol and marijuana use among adolescents. Increased efforts to prevent and intervene in sleep problems among adolescents are warranted.
