Abstract

BACKGROUND: Mental health disorders including major depressive disorder (MDD) are well recognized as major contributors to the global burden of disease among adolescents. The prevalence of adolescent depression is estimated to have increased by at least 25% during the COVID-19 pandemic, compounding the already challenging problem of insufficient mental health service and service accessibility that existed prepandemic. Omega-3 polyunsaturated fatty acid (PUFA) supplementation is currently recommended as a preventive treatment for depression in high-risk adults as well as a second-line monotherapy for adults with mild to moderate MDD, and adjunctive to antidepressants for adults with moderate to severe MDD. The benefits of omega-3 PUFA intake on depressive illness have been hypothesized to occur as a result of their effect on neurotransmission, maintenance of membrane fluidity, and anti-inflammatory action. A comprehensive synthesis and quantification of the existing evidence on omega-3 PUFA's efficacy in treating depression among children and adolescents is essential for clinicians to provide informed guidance to young people and their families, especially considering the absence of current guidelines for this age group.

OBJECTIVES: Primary objective To determine the impact of omega-3 PUFA supplementation versus a comparator (e.g. placebo, wait list controls, no treatment/supplementation, or standard care) on clinician-diagnosed depression or self-reported depression symptoms…
