However, anxiety was associated with insomnia and sleep onset latency also among youth with low levels of depressive symptoms. Adolescents’ depressive symptoms accounted for most of the anxiety-sleep associations, emphasizing the importance of depressive symptoms for sleep. Furthermore, all anxiety symptom sub-types were associated with insomnia and sleep onset latency, whereas most anxiety subtypes were associated with sleep duration. Total anxiety symptoms were related to all sleep variables after controlling for age and sex. Results showed that 38.1% of the adolescents met criteria for insomnia, 34.8% reported short sleep duration (<7 h), and 83.1% reported long sleep onset latency (≥30 min). In the current study self-reported anxiety, insomnia, sleep onset latency, sleep duration, and depressive symptoms were assessed in 313 adolescents (12–16 years mean age 14.0, SD = 0.84, 84.0% girls) referred to treatment for anxiety within primary health care. There is limited knowledge about sleep in adolescents with elevated levels of anxiety treated within primary health care settings, potentially resulting in sleep problems not being sufficiently addressed by primary health care workers. 10Division of Psychiatry, Stavanger University Hospital, Stavanger, Norway.9Sorlandet Hospital HF, Kristiansand, Norway.8Department of Psychology, University of Oslo, Oslo, Norway.
