Problematic parental substance use, childhood family structures and adverse outcomes in young adulthood

Abstract

Aim: The aim of the present study was to investigate the association between childhood family structures, including the presence or absence of problematic parental substance use (PPSU), and adverse outcomes during adolescence/young adulthood. Methods: The study population included 9,770 young people (aged 15–25 years) from samples drawn for two national surveys in Denmark during 2014–2015. By combining surveys with national register data, five types of childhood family structures were constructed based on whether the child experienced PPSU and/or family separation and the number of years the child lived with a parent with substance use problems. Using binary logistic regression models, the relationships between family structure and adverse outcomes in young adulthood (i.e., hospital admissions, mental disorders and criminality) were investigated. Results: Young people who experienced PPSU and did not live with both parents had higher odds of the different long-term adverse outcomes compared with young people who did not experience PPSU, and similar odds of the outcomes compared to youth who had not experienced PPSU and did not live with both parents. The highest odds of adverse outcomes were found among young people who experienced PPSU and lived with the parent with substance use problems for less than five years. Conclusions: Living with both parents protected against adverse outcomes in young adulthood, and if PPSU was present, the odds of adverse outcomes increased. The hypothesis that there would be a positive association between years living with a parent with substance use problems and adverse outcomes in young adulthood was not supported. Awareness should be raised in health service, educational and legal institutions about the risk for young people from families with PPSU who do not live with both parents.

Evidence for improving welfare services

“…A conclusion from a study by Frederiksen et al (2023) is that health service, educational and legal institutions should be very aware of the risk for young people from families with problematic parental substance use (PPSU) who do not live with both parents. They studied the association between childhood family structures, including the presence or absence of PPSU and adverse outcomes during adolescence/young adulthood in a sample population including 9,770 young people (aged 15–25 years).…”
