Air Pollution Tied to Higher Suicide Risk in Global Evidence Review
Key Takeaways
- A pooled data analysis published in the Journal of Epidemiology & Community Health examined 45 eligible studies on pollution and suicide-related outcomes.
- Short-term PM2.5 (13 studies) and PM10 (7 studies), plus long-term PM2.5 (6 studies) and NO2 (7 studies), were statistically significantly associated with suicide risk.
- Of the 45 studies, 33 looked at death by suicide, 7 at suicidal thoughts and 5 at attempted suicide; 38 focused on air pollution, with water, noise and light pollution represented by only a few studies each.
- Evidence was drawn from English-language studies published between January 2010 and April 2024, with 29 studies pooled and 16 summarized narratively.
