Substance abuse

Harmful use of alcohol and drugs can begin early in life, and an early onset, compared to a late onset, is related to a poorer prognosis, higher morbidity, and higher mortality.

Early onset of alcohol use disorder

This study aims to increase knowledge about alcohol consumption and alcohol use disorder among adolescents and young adults. We aim to study how alcohol consumption develops over time, the prevalence across different groups, and how to accurately detect and diagnose alcohol use disorder and problematic drinking. Alcohol use disorder is considered to arise from an interaction between genetic and environmental factors. By assessing young people from the general population at several time-points on a wide range of risk and protective factors, including genetic variation and exposure to traumatic experiences, we can identify factors that may be relevant for the development of alcohol consumption and alcohol use disorders. In addition, two groups of young adult psychiatric patients recruited 10 years apart will be examined in order to assess changes in alcohol consumption over time in risk populations. The Alcohol Use Disorders Identification Test (AUDIT) is a screening instrument for alcohol use/risky use. The diagnostic reliability of the Swedish AUDIT for young psychiatric patients will be evaluated within this study.

The project is a collaboration with the Center for Clinical Research (CKF) in Västmanland and Sörmland. Senior researchers are Johan Isaksson, Adriana Ramirez and Mia Ramklint. Sofia Lenninger is a PhD student in the project.
