Objective: Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important. Participants and methods: A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk-…

Background: Adolescents' school engagement, mental health, and substance use have been major concerns during the COVID-19 pandemic, particularly given disruptions to school instruction. We examined how the instructional setting was associated with academic and health-related outcomes within an adolescent cohort followed during the pandemic.…

The purpose of this study is to identify the prevalence and factors associated with weapon carrying in Colombian high-school students. A cross-sectional study was designed to analyze this phenomenon among students aged between 13 and 17 years. A sample of 1462 students participated, 18.46% of which reported having planned suicide, 56.16% reported…

Objectives: It has been suggested that students are healthier in schools where more students are committed to school. Previous research has examined this only using a proxy measure of value-added education (a measure of whether school-level attendance and attainment are higher than predicted by students' social profile), finding associations with…

The literature is equivocal regarding the role of internalizing problems in the etiology of adolescent substance use. In this study, we examined the association of internalizing and externalizing behavior problems and their co-occurrence with early adolescent substance use to help clarify whether internalizing problems operate as a risk or…

Family structure is associated with a range of adolescent risk behaviours, with those living in both parent families generally faring best. This study describes the association between family structure and adolescent risk behaviours and assesses the role of the family meal. Data from the 2006 Health Behaviour in School-Aged Children survey were…

Background: The study of gene-environment interactions (G by E) is one of the most promising strategies to uncover the origins of mental disorders. Replication of initial findings, however, is essential because there is a strong possibility of publication bias in the literature. In addition, there is a scarcity of research on the topic originated…

It is still under debate whether the reported effects of opioid maintenance therapy (OMT) on child behaviour are a direct effect of prenatal exposure, or whether other factors are involved. This prospective cohort study investigated three models: the teratogenic risk model, the maternal risk model, and a combined risk model in a group of 35…

Mothers were allowed to choose between two different family-based adolescent alcohol-drug prevention strategies and the choice was examined in relation to parent and teen characteristics. Under real world conditions, parents are making choices regarding health promotion strategies for their adolescents and little is known about how parent and teen…

In this study, based on Family Interactional Theory (FIT), the authors tested a longitudinal model of the intergenerational effects of the grandmothers' parent-child relationships and the grandparents' smoking on the grandchildren's externalizing behavior via parents' psychological symptoms, tobacco use, and child rearing. Using Mplus, the authors…

The identification of developmentally specific windows at which key predictors of adolescent substance use are most influential is a crucial task for informing the design of appropriately targeted substance use prevention and intervention programs. The current study examined effects of conduct problems and depressive symptomatology on changes in…

Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are…

This article used the Project on Human Development in Chicago Neighborhoods (PHDCN) data to examine the relationship between exposure to intimate partner violence (IPV) and child behavior problems (externalizing and internalizing), truancy, grade repetition, smoking, drinking, and use of marijuana. Longitudinal data analysis was conducted on 1,816…

This retrospective cross-sectional paper examines the relationship between maternal smoking during pregnancy and children's behavioural problems at 9 years of age independent of a wide range of possible confounders. The final sample comprised 7,505 nine-year-old school children participating in the first wave of the Growing Up in Ireland study.…

Injury is a leading cause of mortality and morbidity among adolescents in developed countries. Jessor and Jessor's Problem Behavior Theory suggests an association between risk behaviors (e.g., smoking, drunkenness, cannabis use, and sexual intercourse) and adolescent injury. The present study examined whether early engagement in risk behaviors…
