Insomnia in adolescent epidemiological studies: To what extent can the symptoms be explained by circadian factors?

Epidemiological studies show a high prevalence of "insomnia" in adolescents. However, insomnia symptoms are not specific for insomnia disorder. Puberty is associated with circadian delay, which may cause insomnia symptoms such as problems falling asleep and daytime impairments, but also difficulties rising in the morning which is not a hallmark of insomnia disorder.

Associations between sleep duration, insomnia, depression, anxiety and registry-based school grades: A longitudinal study among high-school students.

This study explored the prospective associations between sleep patterns, mental health and registry-based school grades among older adolescents. In the spring of 2019, 1st year high-school students in Western Norway were invited to a survey assessing habitual sleep duration, insomnia, depression and anxiety. Sleep patterns, depression and anxiety were assessed using the Munich ChronoType Questionnaire, the Bergen Insomnia Scale, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7.

Elastic Bands Improve Oral Appliance Treatment Effect on Obstructive Sleep Apnoea: A Randomised Crossover Trial.

Background: Oral appliances (OAs) that limit mouth opening during sleep, such as monobloc appliances, have shown superior treatment effects in subgroups of patients with obstructive sleep apnoea. The application of elastic bands on bibloc appliances may resemble these benefits.

Objectives: The primary objective was to investigate if application of elastic bands to bibloc appliances improves treatment success (> 50% reduction of respiratory event index (REI)), in addition to other subjective variables.

Food insecurity in Norway: A cross-sectional study among patients visiting their general practitioner.

Aims: We aim to address the knowledge gap surrounding food insecurity in general practice in Norway, focusing on its prevalence among patients, sociodemographic correlates and its relationship with chronic diseases across different age groups.

Methods: This study is cross-sectional, collecting data through 69 general practice clinics in 2022 from patients >18 years old visiting their general practitioner. They answered an anonymous questionnaire with the Cornell-Radimer hunger scale.
