The mental health impact of the 2023 earthquakes on the Syrian population: cross-sectional study.

Background: Natural disasters have a significant impact on the mental health of affected populations. The February 2023 earthquakes in Syria and Turkey caused widespread devastation.

Aims: To explore the mental health impact of the earthquakes in Syria on the population across areas differentially damaged by the disaster.

Method: This cross-sectional study conducted in Syria included 1406 adults recruited via social media platforms 1 month after the February 2023 earthquakes. Demographic information, earthquake exposure questions, the PTSD Checklist for DSM-5 (PCL-5: for probable post-traumatic stress disorder, PTSD), the Patient Health Questionnaire-9 (PHQ-9: for probable depression) and the seven-item Generalized Anxiety Disorder scale (GAD-7: for probable anxiety) were included to compare outcomes across areas severely, moderately and slightly damaged by the earthquakes.

Results: Probable PTSD and GAD rates were higher in the severely (57.9 and 57.3% respectively) and moderately damaged regions (55.4 and 56.3% respectively) than in the slightly damaged regions (44.6 and 48.3% respectively) (PTSD: < 0.001, GAD: = 0.005). More participants in severely damaged regions (60.6%) reported symptoms of depression compared with moderately (53.1%) and slightly damaged (50.8%) regions ( = 0.003). Poorer mental health outcomes were associated with being female, single, younger, having a damaged or destroyed house, seeing something tragic in person and hearing tragic stories. Seeing something tragic on social media was not statistically significant.

Conclusions: This study highlights the higher prevalence of probable mental disorders in areas with more severe earthquake damage, with over 50% of the population reporting probable PTSD, depression or anxiety. The study also suggests a significant cumulative effect of these earthquakes on an already trauma- and disaster-affected population.
