    Abstract:
    INTRODUCTION: Post-traumatic stress disorder (PTSD) is a prevalent challenge faced by individuals following traumatic events. Given the substantial impact of PTSD on the well-being of young people, comprehensive assessment of the available evidence can inform more effective prevention and intervention strategies to support the mental health and resilience of children in the African context. Despite its high incidence, there has been no up-to-date systematic synthesis of evidence to measure the magnitude of PTSD in pediatric populations in Africa. This systematic review and meta-analysis aim to quantify the prevalence of PTSD and identify associated factors in this vulnerable population. METHODS: A systematic search was conducted across multiple databases, including PubMed, Embase, Scopus, Science Direct, and the search engines Google Scholar and Google, covering the period from 2014 up to May 15, 2024. The primary objective of this search was to identify relevant studies. Subsequently, a meta-analysis was performed using random-effects models to estimate the pooled effect size for each outcome of interest. Additionally, subgroup analysis was conducted to explore potential sources of heterogeneity, with study characteristics considered as covariates. RESULTS: The pooled prevalence estimate for post-traumatic stress disorder (PTSD) among pediatric individuals was 36% (95% CI: 28-44%). Notably, significant heterogeneity existed among the studies (I2 = 98.41%, p value < 0.001), prompting us to employ a random effect model analysis. Furthermore, our meta-analysis revealed that children above 14 years of age and those who experienced family deaths due to traumatic events were significantly associated with PTSD. CONCLUSION: This systematic review and meta-analysis revealed that the prevalence of PTSD among pediatric individuals aged 0-18 years in Africa was high. Notably, older children and those who experienced family deaths due to traumatic events were at a significantly higher risk of developing PTSD. These findings underscore the need for early intervention, age-specific support, and trauma-informed care to address the mental health challenges faced by pediatric populations.
