Article
Background Suicide is a significant public health issue. Many risk prediction tools have been developed to estimate an individual’s risk of suicide. Risk prediction models can go beyond individual risk assessment; one important application of risk prediction models is population health planning. Suicide is a result of the interaction among the risk...

Full-text available
Suicide is a complex, multidimensional event, and a significant challenge for prevention globally. Artificial intelligence (AI) and machine learning (ML) have emerged to harness large-scale datasets to enhance risk detection. In order to trust and act upon the predictions made with ML, more intuitive user interfaces must be validated. Thus, Interpr...

Objective Alcohol use is a known risk factor for suicidality, yet this relationship has not been explored during the pandemic in Canada. As a growing body of evidence demonstrates the negative impact of COVID-19 on alcohol consumption and associated harms in Canada, there is a need to examine this more closely. Methods Using the Survey on COVID-19...

Article
Introduction Polysubstance use—the use of substances at the same time or close in time—is a common practice among people who use drugs. The recent rise in mortality and overdose associated with polysubstance use makes understanding current motivations underlying this pattern critical. The objective of this review was to synthesize current knowledge...
Article
Background Maternal depression is negatively associated with cognitive development across childhood and adolescence, with mixed evidence on whether this association differs in boys and girls. Herein, we performed a systematic review and meta-analysis of sex-specific estimates of the association between maternal depression and offspring cognitive ou...
Article
Background Peer victimization is associated with an increased risk for depression, but there is less evidence on how certain factors such as friend support can buffer this association. This study investigated the associations between friend support and depressive symptoms among victimized and non-victimized adolescent girls and boys from South Kore...

Cross-national evidence is lacking on the association between food insecurity and mental health in youth populations, and on state fragility as a social determinant of these experiences. We analysed data from six cycles of the Gallup World Poll (2014-2019), an annual survey that contains multi-item scales of food insecurity, mental health problems...
Article
Full-text available
Importance Mental health problems are common during the transition from adolescence to young adulthood. Although perceived social support and mental health problems have been shown to be concurrently associated, longitudinal studies are lacking to document the directionality of this association, especially in emerging adulthood (late teens to late...
Article
Food insecurity contributes to various stress-related health problems and previous research found that its association with mental illness is stronger in more affluent countries. We hypothesised that this pattern is a function of relative deprivation whereby the severity of individual food insecurity relative to others in a reference group determin...
Article
Aim: The issue of youth who are not engaged in education, employment or training has been a focus of policymakers for decades. Although interventions exist for these youth, they often measure success in ways that fail to capture what youth seek to gain. The project aims to address this gap by assessing youth-oriented outcomes for interventions tar...

Article
Background: Maternal education in a child's early life may directly affect the child's adult cardiometabolic health, but this is difficult to disentangle from biological, social, and behavioral life course processes that are associated with maternal education. These processes may also differ between males and females. Methods: Using data from th...
Article
In Reply We appreciate the thoughtful question from Jarret et al regarding the items added to the Family Affluence Scale between the 1994 and 2014 cycles of the Health Behavior in School-aged Children study and whether these changes may have affected the association between early-life income inequality and bullying in adolescence.¹ Although socioec...

Background: Caring for a child with a neurodisability (ND) impacts the financial decisions, relationships and well-being of family members, but evidence on the economic trajectories of families throughout the life course is missing. Methods: Using data from the Panel Study of Income Dynamics, we tracked the families of 3317 children starting 5 y...
Article
Evidence suggests that the timing of sleep (chronotype) impacts mental health in young people, but previous studies have not accounted for sleep duration or school start time in this association, or examined a broad range of mental outcomes. In this study, we investigated the association between chronotype and mental health in a representative samp...
Article
Importance While the association between income inequality and interpersonal violence has been attributed to the psychosocial effects of inequality (eg, increased class anxiety, reduced social capital), longitudinal evidence for this pathway is limited by a reliance on small ecological studies and cross-sectional data. The developmental consequence...
Article
Objective: New research suggests that the timing of sleep, or chronotype, affects the mental well-being of adolescents, however evidence of its links to physical health is limited.

Article
Background Research findings over the past two decades have improved our understanding of schizophrenia and related disorders, including their onset and early course.

Article
Background: Scant evidence exists on the relation between the availability of health professionals and adolescent health, and whether the size of the health workforce equally benefits adolescents across socioeconomic strata. Methods: We conducted a cross-sectional analysis of adolescent health in 38 countries. Data from 218 790 adolescents were...
Article
Objective: Recent studies suggest that youth who have a mental health problem are more likely to be NEET-not in education, employment, or training-but findings remain mixed, and evidence from Canada is limited. We examined this association across a range of mental and substance disorders in a representative sample of Canadian youth. Method: Data...
Article
Full-text available
Purpose: The early phases of psychosis, including the prodrome, often feature educational/occupational difficulties and various symptoms and signs, that can render or keep youths "Not in Employment, Education or Training" (NEET).
