Living Near Freeways May Harm Kids' Lungs
California Study Shows Children Housed Near Major Highways Have Slower
Lung Development
Jan. 26, 2007(AP)

Quote
"Since lung development is nearly complete by age 18 years, an
individual with a deficit at this time will probably continue to have
less than healthy lung function for the remainder of his or her life."
--------------------------------------------------------------------------------
W. James Gauderman, Ph.D., researcher, in the study report
 
(WebMD) Children living close to freeways may have slower lung
development between ages 10 and 18 than those living farther away. 

That's according to a study of more than 3,000 southern California
children, published in The Lancet's online edition. 

"Since lung development is nearly complete by age 18 years, an
individual with a deficit at this time will probably continue to have
less than healthy lung function for the remainder of his or her life,"
write researcher W. James Gauderman, Ph.D., and colleagues. 

The study may raise "important questions for society about the
structure of the transportation system, engines, fuels, combustion, and
road dust in urban areas," editorialists write in The Lancet. 

Gauderman works in the University of Southern California's preventive
medicine department. He and his team studied 3,677 children in 12
communities in southern California. 

The children were in the fourth grade (average age: 10 years) when the
study started in the 1990s. They took yearly lung function tests for up
to eight years. 

Children 10 to 18 go through a period of rapid lung development, the
researchers note. 
The researchers also looked at how close the children lived to freeways
and found that 440 lived less than a third of a mile from one. 

Their results showed that the children living that close to a freeway
had slower lung development during the study, compared with those living
at least three times farther from a freeway. 

The findings held after the researchers took other factors into
account, including family income, race, asthma, smoking, regional air
quality, and kids who moved during the study. 

Local roads that weren't freeways were not associated with slower lung
development. The children weren't followed beyond age 18, so it's not
clear how well their lungs functioned later in life. 

The concentration of pollutants in the area near major freeways may be
the problem, but it's hard to rule out other influences, note Gauderman
and colleagues. 

It's also not clear what factors, if any, influenced the kids' lung
development before age 10, say the editorialists. They included Thomas
Sandstrom, M.D., Ph.D., of the respiratory medicine and allergy
department of University Hospital in Umea, Sweden. 

"However, these questions should not distract from the major
achievement of follow-up of such a large group of children through
secondary school with repeated lung function tests," write the
editorialists. 

The study was funded in part by the California Air Resources Board, the
National Institute of Environmental Health Sciences, and the
Environmental Protection Agency.

Inefficient, dirty energy and transportation systems are now the norm.
Inefficient, dirty energy and transportation systems must become the
exception to the standard, not the norm.
