Brief Summary

Prescription of analgesic, sedative, and anxiolytic medication for children and adolescents is increasing in Western countries. In recent decades, rates have also increased in Norway, despite a relatively restrictive prescription practice. Analgesics, sedatives, and anxiolytics are among the medications most commonly prescribed to young people by general practitioners and others. Overuse of such medication adversely impacts individual and societal health, social and economic measures. For example, the risk of chronification of pain, development of addiction, and dropout from school and the workforce is high. Epidemiological research has largely failed to integrate vulnerable, young service users' perspectives in planning, interpretation and dissemination of results. This has resulted in limited identification of potential causes for the increasing exposure to prescription and overuse of analgesics and other addictive drugs among of children and adolescents, and the long-term consequences this may have for morbidity and addiction in early adulthood. Knowledge of early risk factors and plausible causal mechanisms is crucial for the development of timely and effective interventions to prevent inappropriate prescriptions in clinical practice. This prospective, longitudinal cohort study examines the use of analgesic, sedative, and anxiolytic medication among about 25,000 children throughout adolescence and young adulthood (1995 to 2020), specifically addressing changes in prescription over time, and early risk factors for the prescription of addictive drugs in adolescence and young adulthood and the subsequent development of mental health disorders.

Study Arms (1)

Young-HUNT

The young-HUNT study is a renowned, representative, population-based study where all adolescents living in the Nord-Trøndelag county have been invited to participate in four subsequent waves, from 1995 to 2019. Information about the study can be found here: https://www.ntnu.edu/hunt/young-hunt. In this study data from the Young-HUNT1-4 studies (1995-2019) will be linked to longitudinal, individual data from the Norwegian prescription Database (NorPD) (2004-2020), providing a unique, longitudinal dataset in which research questions will be explored. To obtain good, reliable follow-up data and outcome measures for the young-HUNT3 participants (2006-2008) the investigators will additionally include longitudinal data from the HUNT4 study of young adults (2017-2019); applicable for those participating in both the YoungHUNT3 and the YoungHUNT4.

Study Population

All youth in Nord-Trøndelag county in Norway between 13-19 years were invited to participate in the four Young-HUNT study waves (1995-2019), and followed up after approximately 10 years between 2017-2020. In this study data from the Young-HUNT1-4 studies (1995-2019) will be linked to longitudinal, individual data from the Norwegian prescription Database (NorPD) (2004-2020), providing a unique, longitudinal dataset. To obtain good, reliable followup data for the young-HUNT3 participants (2006-2008) the investigators will additionally include longitudinal data of for those participating in both the YoungHUNT3 and the YoungHUNT4 (2017-2019).
