Clean air extends life by 5 months, study says

January 22, 2009 by  

Tackling pollution is a public health issueCleaning up air pollution has the power to significantly benefit public health, extending life expectancy by approximately five month, a new study shows.

Researchers at Brigham Young University and Harvard School of Public Health say that average life expectancy in 51 American cities has risen in the past couple of decades, in part due to cleaner air.

The scientists acknowledged that there are a number of factors that influence how long people live, but said the results show the country is "getting a substantial return on investments in improving our air quality."

"Such a significant increase in life expectancy attributable to reducing air pollution is remarkable," lead author Dr C. Arden Pope III commented.

As part of the study, the team compared two sets of data from the cities, which took into account changes in air pollution in 1980 and 2000, as well as life expectancy.

They also used statistical modeling to account for factors such as population change, income, demographics and smoking.

Long-term exposure to air pollution is thought to affect blood pressure, heart attack risk and the chances of dying from cardiovascular disease and lung cancer.

    It’s like motherhood and apple pie. We want it and we must have it before we all smother. Meanwhile on a personal basis, we can combat air pollution by improving indoor air. All research says that indoor air pollution is worse than outdoor. I’m a firm believer in the Airwise Air Purifiers from Health Resources (1-800-471-4007).

    What a bunch of crap. How much did we spend on this stupid study? Probably some taxpayer financed boondoggle. Such a “substantial” return on investment. What investment? How much did this investment cost? Who reviewed this study? An article with the researchers touting their own research, huh? Sounds unbiased to me. Get this crap out of here. If you are going to cite a study, at least provide some evidence that the study is even valid. This is a very disappointing article for Livingston to allow to be published.

    And you touting your clean air devices should be ashamed as well. This should be a forum for open discussion of important issues, not a place for you to hawk your products.
