Association between exposure to air pollution and increased ischaemic stroke incidence: a retrospective population-based cohort study (EP-PARTICLES study)
To examine the association between short-term exposure to specific air pollutants (PM2.5, NO2, B(a)P, SO2) and ischaemic stroke (IS) incidence.
Key Findings:
Recorded 146,262 cases of IS, predominantly in females (51.8%) and individuals over 65 years old (77.6%).
Exposure to PM2.5, NO2, B(a)P, and SO2 increased IS risk by 2.4%, 1%, 0.8%, and 0.6% respectively on the day of exposure.
Age and sex modified the effects of PM2.5, NO2, and B(a)P, with more pronounced effects in non-elderly individuals and women.
Residents in regions with high tobacco and alcohol consumption were more sensitive to PM2.5 and SO2 effects.
Response–effect curves were non-linear and steeper at lower concentrations.
Interpretation:
Air pollution exposure, even at low levels, is associated with increased IS incidence, particularly affecting non-elderly women and exacerbated by harmful lifestyle habits, highlighting the need for targeted public health interventions.
Limitations:
The study is retrospective and may be subject to confounding factors.
Data on individual lifestyle habits were not comprehensively collected.
Potential impact of unmeasured confounding factors.
Conclusion:
Short-term exposure to air pollution is linked to higher IS incidence, emphasizing the need for public health interventions, especially for vulnerable populations.
