(HealthDay News) -- Long-term exposure to the air pollution particles caused by traffic has been linked to an increase in blood pressure, U.S. researchers say.
In the new report, researchers analyzed data from 939 participants in the Normative Aging Study, who were assessed every four years between 1995 and 2006. A computer model was used to estimate each participant's exposure to traffic air pollution particles during the entire study period and for the year preceding each four-year assessment.
Increased exposure to traffic pollution particles was associated with higher blood pressure, especially when the exposure occurred in the year preceding a four-year assessment (3.02 mm Hg increase in systolic blood pressure, 1.96 mm Hg increase in diastolic pressure, and 2.30 mm Hg increase in mean arterial pressure), the study authors reported in a news release from the American Heart Association.
