Patterns of psychiatric healthcare use during pandemic times among boys and girls with pre-existing diagnoses: a Norwegian nationwide primary and specialist healthcare registry study.

Background: The COVID-19 pandemic introduced complexities that were likely more demanding for some groups, such as children and adolescents, and especially those with pre-existing mental health diagnoses. This study examines long-term patterns of psychiatric healthcare use among this vulnerable group, providing insights into shifts in psychiatric healthcare use during a global health crisis.

Methods: We use data from the primary and specialist healthcare registries available from the Norwegian emergency preparedness register for COVID-19 (Beredt C19) to estimate patterns of psychiatric healthcare use.

Age of migration and common mental disorders among migrants in early adulthood: a Norwegian registry study.

Background: Younger age of migration is associated with higher risk of psychotic disorders but the relationship between age of migration and common mental disorders is less clear. This study investigates the association between age of migration and diagnosed common mental disorders among migrants living in Norway.

Methods: Using national Norwegian register data from 2008 to 2019, we compared the odds of a common mental disorder diagnosis in healthcare services during early adulthood among non-migrants, descendants and migrants with different ages of migration and lengths of stay.

Morbidity among Adolescent Hypnotic Drug Users in Norway: An Observational Population-Based Study.

We have previously shown that the use of hypnotic drugs increased among young Scandinavians during 2012-2018. This study aimed to explore psychiatric and somatic morbidity among adolescent hypnotic drug users in a cohort study of 13-17-year-old individuals during 2008-2018 in Norway. Data sources were (i) prescription data from the Norwegian Prescription Database linked to specialist health care diagnoses from the Norwegian Patient Registry and (ii) sleep disorder diagnoses from the Primary Health Care Database.
