Odds ratios were adjusted for presence of obstructive sleep apnea, age, gender, ethnicity, family income and parent education. Insomnia was defined as presence of at least one of the following symptoms: trouble falling asleep, staying asleep, or waking up too early in the morning. ICSD2-derived insomnia was determined by the International Classification of Sleep Disorders (ICSD2) criteria. ICSD2-derived insomnia required the presence of at least one of the following symptoms: trouble falling asleep, staying asleep, or waking up too early in the morning, in addition to reporting adequate time in bed (≥9 hours) and the presence of at least one of the following daytime symptoms: learning problems, daytime sleepiness, or concern about not getting enough sleep. OR: Odds ratio, CI: confidence interval.
