Abstract Study Objectives Sleep problems and symptoms of attention-deficit hyperactivity disorder (ADHD) in adolescence are common. Little is known about the prospective the prospective associations between sleep and subsequent ADHD symptoms in adolescents. This study examined the prospective associations between sleep problems and subsequent ADHD symptoms in a large sample of adolescents. Methods Participants included 7072 adolescents from the Shandong Adolescent Behavior and Health Cohort (SABHC) study in Shandong, China. Participants were initially assessed in November–December of 2015 and were reassessed 1-year later in 2016. Sleep duration, sleep problems, and psychosocial information were collected using a structured questionnaire. ADHD symptoms were measured by the Achenbach Child Behavior Checklist-Youth Self-Report. Results At baseline, 7.6% participants had clinically relevant ADHD symptoms, which were highly comorbid with sleep problems including insomnia symptoms, poor sleep quality, symptoms of restless legs syndrome (RLS), frequent snoring, and short sleep duration. Of the 6531 participants without clinically relevant ADHD symptoms at baseline, 4.5% reported clinically relevant ADHD symptoms at 1-year follow-up. After adolescent and family covariates were adjusted for, insomnia (OR = 2.09, 95% CI = 1.45–3.02), RLS (OR = 1.47, 95% CI = 1.02–2.11), and frequent snoring (OR = 2.30, 95% CI = 1.36–3.90) were all significantly associated with subsequent ADHD symptoms. Conclusion ADHD symptoms and sleep problems are highly comorbid. Insomnia, RLS and frequent snoring appear to be significant predictors of subsequent ADHD symptoms. Our study highlights the importance of assessing and managing sleep problems for prevention and clinical treatment of ADHD symptoms in adolescence.
