This meta-analysis examined the prevalence of PTSD, depression, and anxiety in adults and youth exposed to wildfires, analyzing 33 studies. The overall prevalence rates were 26.6% for PTSD, 28.9% for depression, and 25.2% for anxiety. Results indicated that assessment timing significantly influenced prevalence estimates, with clinically relevant levels persisting even months post-exposure.
Key findings
- PTSD prevalence was 26.6%, with a 95% CI of [19.7, 33.5].
- Depression prevalence was 28.9%, with a 95% CI of [22.5, 35.2].
- Anxiety prevalence was 25.2%, with a 95% CI of [19.3, 31.1].
- Prevalence rates remained above 14% for each disorder several months after wildfire exposure.
Why it matters
Understanding the mental health impact of wildfires is crucial for clinicians, as it underscores the need for timely interventions and ongoing support for affected individuals, particularly in the aftermath of such traumatic events.
