Table 2.

Linear mixed-effects models estimating the change in blood pressure of study participants associated with a 2-SD increase* in long-term exposure to PM2.5 ambient levels (n=36).

PM2.5 6-month
 PM2.5 1-year
mmHg 95% CI p-value mmHg 95% CI p-value
Systolic blood pressure 0.19 (0.11, 0.28) <0.01 0.12 (0.02, 0.19) 0.01
Diastolic blood pressure 0.11 (−0.03, 0.28) 0.13 0.05 (−0.07, 0.17) 0.43
*

Corresponding to a 2.76 μg/m3 increase in 6-month and to a 2.39 μg/m3 increase in PM2.5 levels. Models were adjusted for age, body mass index, smoking, C-reactive protein, white blood cells distribution (percentage of B-cells, monocytes, NK-cells, CD4, and CD8), and number of platelets. 95% CI: 95% Confidence interval.
