Effect of air pollution on blood pressure, blood lipids, and blood sugar: a population-based approach.

OBJECTIVE

To investigate changes in blood pressure, lipids, and sugar associated with changes in exposure to ambient air pollution.

METHODS

We conducted secondary analyses of blood pressure and biochemistry markers from Taiwanese Survey on Prevalence of Hyperglycemia, Hyperlipidemia, and Hypertension and air pollution monitoring data in 2002 by applying generalized additive models.

RESULTS

We observed increased particulate matter with aerodynamic diameters <10 microm was associated with elevated systolic blood pressure (an interquartile range, 34 microg/m, for 0.47 mmHg; 95% CI, -0.09 to 1.02), triglyceride, apolipoprotein B, hemoglobin A1c, and reduced high-density lipoprotein cholesterol. Elevated ozone was associated with increased diastolic blood pressure, apolipoprotein B, and hemoglobin A1c.

CONCLUSIONS

Alterations of atherosclerotic indicators are associated with particulate matter with aerodynamic diameters <10 microm and ozone changes. This might provide a link between air pollution and progression of atherosclerotic cardiovascular diseases.
