Title: | Changing places to study short-term effects of air pollution on cardiovascular health: a panel study | Authors: | Scheers, Hans NAWROT, Tim Nemery, Benoit CASAS RUIZ, Lidia |
Issue Date: | 2018 | Publisher: | BMC | Source: | ENVIRONMENTAL HEALTH, 17 (Art N° 80) | Abstract: | BackgroundShort-term exposure to ambient air pollution triggers acute cardiovascular events. Here, we evaluate the association of exposure to ambient air pollution with two intermediate cardiovascular endpoints: blood pressure and carotid stiffness.MethodsIn a one-year panel study, we included 20 healthy volunteers (10 male-female couples aged 59-75years) with air pollution and health parameters measured every two months at their region of residence (Leuven, Belgium) and twice during two ten-day periods in two locations, one with higher (Milan, Italy) and one with lower (Vindeln, Sweden) air pollution levels (220 observations). We measured blood pressure, carotid arterial stiffness, personal exposure to NO2, and ambient concentrations of PM10, PM2.5, and NO2. We used linear mixed models to evaluate the associations between the health outcomes and the air pollutants.ResultsCompared with Leuven, exposure to pollutants was higher in Milan and lower in Vindeln, with the highest contrast for NO2 (median 20.7g/m(3) (IQR:7.4) vs 65.1g/m(3) (9.0) and 4.5mg/m(3) (0.8), respectively). We did not observe significant associations between either systolic or diastolic blood pressure and variations in air pollution. However, we found significant associations between arterial stiffness and 5day average exposure to the studied pollutants. The strongest associations were observed for PM10 with carotid distensibility (DC) and compliance (CC) coefficients, and the young elastic modulus (YEM): 4.3% (95%CI:7.0;1.5) increase in DC, 4.7% (95%CI:7.1;2.3) increase in CC and 4.2% (95%CI:1.1;7.3) decrease in YEM for each 10g/m(3) decreases in PM10.ConclusionsOur study suggests that short-term exposure to air pollution results in reductions in carotid elasticity among elderly population. | Notes: | [Scheers, Hans; Nawrot, Tim S.; Nemery, Benoit; Casas, Lidia] Katholieke Univ Leuven, Dept Publ Hlth & Primary Care, Environm & Hlth Unit, Herestr 49,O&N 1,PB 706, B-3000 Leuven, Belgium.
