Smog Tougher on the Obese

THURSDAY, Oct. 15 (HealthDay News) -- Air pollution appears to hit the obese hardest, causing significant increases in blood pressure, a new study finds.

Air pollution has been linked to a variety of health problems including asthma, heart disease and diabetes, but this is the first time obesity has been taken into account, researchers say.

"For those who are obese, exposure to air pollution further exacerbated systolic blood pressure and pulse pressure," said lead researcher Srimathi Kannan, an assistant professor at the School of Public Health and Health Sciences of the University of Massachusetts at Amherst.

"When you are looking at environmental exposures and medical outcomes, you have to consider obesity," Kannan said.

The report is published in the Oct. 16 online edition of the Journal of Epidemiology and Community Health.

For the study, Kannan and colleagues collected data on air pollution and health as part of the Healthy Environments Partnership study. The study looked at these factors in 919 households in areas of Detroit that included rich and poor neighborhoods and a mix of racial and ethnic groups.
