Particulate air pollution may increase risk of high blood pressure
German researchers have said that people who live in cities where particulate air pollution is high may have an increased risk of high blood pressure.
Earlier studies have shown acute increases in particulate air pollution, such as day-to-day fluctuations, can raise blood pressure, senior study Dr. Barbara Hoffman of the University of Duisburg-Essen says. Hoffman and colleagues used data from the Heinz Nixdorf Recall Study, an ongoing of study of heart disease of almost 5,000 people from 2000 to 2003.
Hoffman says in a statement, "Our results show that living in areas with higher levels of particle air pollution is associated with higher blood pressure."
The study finds average arterial blood pressure rose by 1.7 mmHg for an increase of 2.4 Âµg/mÂ³ in the exposure level to fine particulate matter, under 2.5 ?m, emitted by traffic, heating, industry and power plants.
Hoffman says in a statement, "Both, systolic and diastolic blood pressure, are higher in people who live in more polluted areas, even if we take important factors that also influence blood pressure like age, gender, smoking, weight, etc. into account. Blood pressure increases were stronger in women than in men." (With Inputs from Agencies)
