NEW YORK (Reuters Health) – In a study of more than 4,000 black women in Los Angeles, those who lived in areas with higher levels of
traffic-related air pollution were at increased risk of developing diabetes and high blood pressure.
The researchers, led by Patricia Coogan at Boston University, found that black women living in neighborhoods with high levels of nitrogen oxides, pollutants found in traffic exhaust, were 25 percent more likely to develop diabetes and 14 percent more likely to develop hypertension than those living in sections with cleaner air.
Previous research has linked air pollution to health problems such as diabetes, stroke, heart disease and even higher rates of death.
“The public health implications are huge,” said Dr. Jiu-Chiuan Chen, who studies the effects of air pollution at the University of Southern California Keck School of Medicine in Los Angeles, especially for black women, who have higher rates of diabetes and high blood pressure than white women. He was not involved in the current work.
Forty-four percent of all black women in the U.S. have high blood pressure and about 11 percent have diabetes compared with 28 percent and roughly seven percent, respectively, of white women, according to the Centers for Disease Control and Prevention.
