Childhood sleep problems, early onset of substance use and behavioral problems in adolescence.
BACKGROUND Very few prospect i ve studies examine the relationship between childhood sleep problems  and subsequent substance use . In this study , we examined how sleep problems at ages 3 - 8 predicted onset of alcohol , cigarette , and marijuana use in adolescence . We also investigated the relationships between childhood sleep problems and adolescent internalizing and externalizing problems . METHODS Study participants were 292 boys and 94 girls from a community sample of high risk families and controls in an ongoing longitudinal study . RESULTS Controlling for parental alcoholism , sleep problems at ages 3 - 8 predicted onset of alcohol , cigarette , and marijuana use among boys and onset of alcohol use among girls . Childhood sleep problems were related to maternal ratings of internalizing and externalizing problems during adolescence for both boys and girls . Adjusting for these problems did not weaken the effects of sleep problems on onset of substance use . CONCLUSIONS This is to our knowledge the first study that prospect ively examines gender differences in the relationship between sleep problems and early onset of substance use . Childhood sleep problems predicted early onset of substance use for boys but not girls . If childhood sleep problems indeed increase the probability of substance use onset , greater attention by parents to  sleep problems in children and adolescents would potentially have ameliorative long-term effects . Parents are encouraged to explore different ways to help their children sleep better , including obtaining information and suggestions from their primary care physicians
