Completed secondary education among youth with prenatal substance exposure: A longitudinal register‐based matched cohort study

Abstract

Introduction:The dual impact of prenatal substance exposure (i.e. alcohol/drugs) and adverse postnatal caregiving environment on offspring secondary education completion is an understudied research area. The aim was to investigate the inluence of childhood adversities, out-ofhome care, and offspring's mental and/or behavioural disorders on secondary education completion among prenatally exposed offspring in comparison to matched unexposed offspring. Methods: This is a longitudinal register-based matched cohort study in Finland including offspring with a history of prenatal substance exposure and a matched unexposed cohort. The study sample included 283 exposed and 820 unexposed offspring aged 18-23 years. Results: The results showed a time lag in secondary education completion and lower educational attainment overall among exposed compared with unexposed (37.8% vs. 51.0%, respectively). The results from the multivariate logistic regression models showed that the differences in the secondary education completion between exposed and unexposed were diminished in the presence of covariates. A cumulative childhood adversity score and out-of-home care were not associated with secondary education completion in the multivariate models, whereas the different domains of offspring's mental and/or behavioural disorders including psychiatric disorders (AOR 0.65, 95% CI 0.45-0.96), neuropsychological disorders (AOR 0.35, 95% CI 0.23-0.54) and dual psychiatric and neuropsychological disorder (AOR 0.29, 95% CI 0.18-0.48) showed an independent negative effect on secondary education completion.
