Abstract

Background: Considering the lack of evidence on incidence and continuity of sleep problems from adolescence to young adulthood, this study explores sleep problems’ incidence and their continuation rates from 14 to 21 years.

Methods: Sleep data from the 14-year (n = 4,924) and 21-year (n = 3660) follow-up of the Mater-University of Queensland Study of Pregnancy cohort were used. Sociodemographic, lifestyle, and psychological conditions were explored for their role in sleep problems. Modified Poisson regression with a robust error variance was used to identify predictors. Inverse probability weights were used to account for attrition.

Results: Of all subjects, 26.0% of the subjects at 14 years and 28.3% of the subjects at 21 years reported “often” sleep problems, with 41.7% of adolescent sleep problems persisting at 21 years. Perinatal and early-life maternal factors, for example, drug abuse (incidence rate ratio (IRR), 1.32; 95% confidence interval [CI], 1.02-1.71), smoking, depression, and anxiety, were significant predictors of adolescent sleep problems. Female sex (IRR, 2.13; 95% CI, 1.55-2.94), advanced pubertal stages, and smoking were the important predictors of sleep problems at 21 years. Adolescent depression/anxiety supported the continuity of sleep problems (IRR, 1.21; 95% CI, 1.05-1.40), whereas exercise was seen to exert a protective effect.

Conclusion: This study indicates high rates of sleep problems in young subjects, with around half of sleep problems originating in adolescence persisting in young adulthood. Therefore, early interventions are needed to manage sleep problems in young subjects and prevent further progression to other life stages. Future studies should explore if sleep problems in young adults also persist in later life stages and identify the factors supporting the continuity of sleep problems.
