Implication

Retrospective cohort study reveals increased cardiovascular and cerebrovascular mortality linked to ambient air pollution in Chinese adults, highlighting severe health risks of chronic exposure.

Key Points

To examine whether long-term exposure to ambient air pollution increases the risk of mortality from cardiovascular and cerebrovascular diseases.
Conducted a retrospective cohort study using 12 years of follow-up data (1998–2009) in Shenyang, China.
Evaluated exposure to ambient air pollutants—particulate matter under 10 µm (PM10), sulfur dioxide (SO2), and nitrogen dioxide (NO2)—with stratified analyses by sex, age, education, and income.
A 10 µg/m³ increase in annual average PM10 was associated with a 55% higher risk of cardiovascular mortality (HR: 1.55; 95% CI: 1.51 to 1.60) and a 49% higher risk of cerebrovascular mortality (HR: 1.49; 95% CI: 1.45 to 1.53).
A 10 µg/m³ increase in NO2 corresponded to an adjusted HR of 2.46 (95% CI: 2.31 to 2.63) for cardiovascular death and 2.44 (95% CI: 2.27 to 2.62) for cerebrovascular death.
Mortality risks associated with outdoor air pollution were notably higher among females, nonsmokers, and individuals with a BMI under 18.5 kg/m².
