Naomi Marmorstein, a researcher in the study, wrote insomnia to be a risk marker for alcohol use, and alcohol use a risk marker for insomnia, among early adolescents. Parents, educators, and therapists should consider this, published in the journal Addictive Behaviors.

Sleep irregularity, defined as the difference in weekday and weekend bedtimes; and disturbed sleep, characterized as nightmares, snoring, sleepwalking, wetting the bed, and talking in sleep.

Marmorstein examined the association between alcohol use and four sleep-related issues: initial insomnia ; daytime sleepiness; sleep irregular and disturbed sleep . Whether symptoms of mental health problems or levels of parental monitoring accounted for these associations, she examined.

The research focused on students of seventh- and eighth-grade participating in the Camden Youth Development Study. The development of mental health problems and resilience among at-risk youth, the study examined.

Researchers asked questions to students about how long it took for them to fall asleep, what times did they go to bed on a weekday and the weekend or vacation night. In addition, how often did they experience sleep disturbances, and whether they ever fell asleep in class or had trouble staying awake after school. They were asked for frequency of any alcohol use in the previous four months.

Students answered questions, which were used to assess depressive symptoms, as well as evidence of conduct disorder symptoms. To determine the presence of attention-deficit hyperactivity disorder symptoms were analyzed by the questionnaires of teachers.

There is an association between alcohol and both insomnia and daytime sleepiness . Marmorstein determined the link between insomnia and alcohol use. Significantly, symptoms of mental health problems and parental monitoring did not account for it.

Researcher mentioned, " Insomnia may be a unique risk marker for alcohol use among young adolescents," Associations between insomnia and alcohol use among older adolescents and adults are consistent with the results, the Rutgers-Camden researcher noted.
