ObjectiveAdolescence is a formative and turbulent phase where physiological, psychosocial, and cognitive changes leave adolescents vulnerable to psychological disorders. Given the lack of reviews that consolidate and compare worldwide prevalence of depression among adolescents, this review aims to examine the global prevalence of major depressive disorders, dysthymia, and elevated depressive symptoms among adolescents.MethodsA systematic review and meta‐analysis was conducted. Six databases were searched for studies published from 2001 to December 2020. Seventy‐two studies were included. Subgroup analysis were performed for year of publication, geographical region, gender, and assessment tools used.ResultsThe global point prevalence rate of elevated self‐reported depressive symptoms from 2001 to 2020 was 34% (95% CI: 0.30–0.38). Point prevalence for major depressive disorder (MDD) and dysthymia was 8% (95% CI: 0.02–0.13) and 4% (95% CI: 0.01–0.07), respectively. The pooled one‐year prevalence and lifetime prevalence for MDD were 8% (95% CI: 0.05–0.12) and 19% (95% CI: 0.12–0.26). Point prevalence of elevated depressive symptoms among adolescents increased from 24% (95% CI: 0.19–0.28) between 2001 and 2010 to 37% (95% CI: 0.32–0.42) between 2011 and 2020. The Middle East, Africa, and Asia have the highest prevalence of elevated depressive symptoms, and female adolescents were reported to have a higher prevalence of elevated depressive symptoms than male adolescents.ConclusionBesides targeting those with existing clinical depression, research and policies should also focus on educational and supportive mitigation efforts to curb depressive symptoms among adolescents before escalation. The findings encourage future research to develop more gender‐specific and culturally relevant intervention programmes.Practitioner points34% of adolescents globally, aged 10‐19 years, are at risk of developing clinical depression, which exceeds the reported estimates of individuals aged 18 to 25 years. Practitioners are highly encouraged to prioritize depression screening and intervention implementation for individuals in this age group.Female adolescents and adolescents from Middle East, Africa, and Asia have the highest risk of developing depression. This urges practitioners and researchers to develop more gender‐specific and culturally relevant intervention programmes.
