Higher levels of air pollution increase the risk of hospitalization
for stroke, especially in warmer weather, according to a new study by researchers
in Taiwan. The findings were published on October 9 in an online edition of Stroke (http://stroke.ahajournals.org/).
The researchers found there were more than 23 000 hospital admissions
for stroke from 1997 to 2000 in Kaohsiung, Taiwan, and compared air pollution
levels on the dates of admission with levels one week before and after admissions.
They found a significant association with two pollutants—particulate
matter and nitrogen dioxide—especially on warmer days (20°C or warmer).
