The Efficacy of Nutritional Interventions in Reducing Childhood/Youth Aggressive and Antisocial Behavior: A Mixed-Methods Systematic Review and Meta-Analysis.

Aggressive/antisocial behaviors in children and youth may result in impairments in family, social, or academic functioning and lead to long-term negative consequences for both the individual and society as a whole. The potential of healthy diet and nutritional supplements to reduce aggression and antisocial behavior is an active area of study in nutritional mental health sciences. The goal of this systematic review is to (1) investigate the effectiveness/efficacy of nutritional interventions (dietary manipulation, fortification or supplementation) in reducing excessive aggression, antisocial behaviors, and criminal offending in children/youth (systematic review and meta-analysis); and (2) provide an overview of implementation barriers and facilitators regarding nutritional interventions in children/youth (qualitative/narrative synthesis).

Mapping the Landscape: A Scoping Review of Evaluated Substance Use Harm Reduction Programs for Youth.

Youth are particularly vulnerable to adverse outcomes from substance use, and there is limited evaluated drug education targeting youth in Canada or the United States of America (US). This scoping review identified and synthesized existing literature on evaluated harm reduction substance use education programs for school-aged youth in Canada and the US. Following the methodological framework outlined by Arksey and O'Malley, a database search identified relevant articles published between 2012 and 2025 through MEDLINE, Scopus, APA PsycInfo, ERIC, Academic Search Complete, Social Work Abstracts, and Embase.
