The role of childhood adversity and prenatal mental health as psychosocial risk factors for adverse delivery and neonatal outcomes.

Objective: Exposure to adverse childhood experiences (ACEs) is a significant predictor for physical and mental health problems later in life, especially during the perinatal period. Prenatal common mental disorders (PCMDs) are well-established as a risk for obstetric interventions but knowledge on combined effects of multiple psychosocial risk factors is sparse. We aim to examine a comprehensive model of ACEs and PCMDs as risk factors for poor delivery and neonatal outcomes.

Effect of the COVID-19 pandemic on adolescent mental health and substance use up to March, 2022, in Iceland: a repeated, cross-sectional, population-based study.

Background: Poor mental health in the first year of the COVID-19 pandemic has been well documented in adolescents; however, less is known about the longer-term effect of the pandemic. We aimed to examine adolescent mental health and substance use as well as covariates associated with these outcomes 1 year or more into the pandemic.

Methods: A nationwide sample of adolescents aged 13-18 years enrolled in school in Iceland were invited to complete surveys administered during October-November or February-March, 2018, October-November, 2020, February-March or October-November, 2021, and February-March 2022.

Depressive symptoms, mental wellbeing, and substance use among adolescents before and during the COVID-19 pandemic in Iceland: a longitudinal, population-based study.

Background: Adolescence represents a crucial developmental period in shaping mental health trajectories. In this study, we investigated the effect of the COVID-19 pandemic on mental health and substance use during this sensitive developmental stage.

Methods: In this longitudinal, population-based study, surveys were administered to a nationwide sample of 13-18-year-olds in Iceland in October or February in 2016 and 2018, and in October, 2020 (during the COVID-19 pandemic).
