Meta-analysis and Systematic Review on Philippine Mental Health and Climate Resilience: Basis for Designing Climate-Resilient Communities through Evidence-based Association of Southeast Asian Nations (ASEAN) Collaborative Strategies and Integrated Disaster Risk Reduction

Key Points

Community-based interventions significantly improve climate resilience and reduce mental health issues, especially PTSD, depression, and anxiety.
Among 32 studies with 45,247 participants, pooled PTSD prevalence was found to be 35.2%, with depression at 18.4% and anxiety at 31.8%.
Meta-analysis conducted following PRISMA guidelines utilized quantitative and qualitative methodologies to synthesize evidence.
Findings highlight the need for culturally tailored interventions and collaborative strategies to address mental health within disaster risk reduction frameworks.

Abstract

Background: Climate change poses unprecedented challenges to community resilience across the ASEAN region, with the Philippines serving as a critical case for investigating links between environmental stressors and community mental health. This meta-analysis and systematic review examine how community-based mental health interventions strengthen climate resilience within disaster risk reduction and resilient infrastructure frameworks.Methods: Following PRISMA guidelines, we searched eight databases for literature published between 2010 and 2025. Quantitative synthesis used Review Manager (v5.4) and R (v4.4.3); qualitative analysis used MAXQDA (2020). GRADE assessment evaluated the certainty of evidence across primary outcomes.Results: Thirty-two studies (N=45,247) revealed substantial climate-related mental health impacts: pooled PTSD prevalence 35.2% (95% CI 28.6-42.1), depression 18.4% (95% CI 14.7-22.8), and anxiety 31.8% (95% CI 25.3-39.1). Meta-regression revealed that disaster type explained 45% of the heterogeneity variance (p 0.01). Protective community factors significantly reduced the mental health burden, including social networks (OR=0.43, 95% CI 0.35-0.52), collective efficacy (OR=0.38, 95% CI 0.29-0.49), and cultural practices (OR=0.58, 95% CI 0.45-0.75). Infrastructure-integrated psychosocial support centers demonstrated 60% greater effectiveness in intervention compared to standalone programs (p 0.001). Women, children, and indigenous communities experienced disproportionate impacts, requiring targeted interventions.Conclusions: Climate-induced mental health impacts require coordinated regional responses within integrated disaster risk reduction frameworks. Aligning with the Sendai Framework priorities, the findings support community-centered, culturally adapted interventions that combine immediate psychosocial support with resilient infrastructure development. ASEAN collaborative strategies are essential for strengthening community mental health systems and advancing Sustainable Development Goals through multi-hazard approaches.
