Experts say sprawl is unhealthy but hard to change

It took Americans decades to forget how to walk, and experts think it could take longer to learn it all over again.

But if nothing changes, people will keep padding on calories they should burn off, setting themselves up for diseases of obesity such as diabetes and heart conditions, the researchers say.

The bleak prognosis follows a series of reports on America's preference for cars over walking or biking. Researchers see the trade of horsepower for footpower as just one way in which the nation has engineered healthful physical activity out of normal living. They say the time has come to engineer its return.

"What we are trying to get people to understand here is the environment could create better choices for them to achieve a healthier lifestyle," said Richard Killingsworth, director of Active Living by Design, a community planning program based at the University of North Carolina, Chapel Hill.


But re-engineering won't be easy. It took decades to make things bad, and change will require "having the will of the people to do this for decades out," Killingsworth said.

Killingsworth is a co-author of a study that compared car-dependent sprawled communities with compact, foot-friendly cities. Weight went up as the degree of sprawl rose, the study said.

The most sprawling counties had a greater proportion of adults with high blood pressure and obesity, said Reid Ewing, an urban planner with the National Center for Smart Growth at the University of Maryland. He completed his research while at Rutgers University. Ewing was lead author of the report in the September/October issue of the American Journal of Health Promotion.

America is not biker- or walker-friendly. American pedestrians are about three times more likely to get killed than German pedestrians, and over six times more likely than Dutch pedestrians, even though Europeans bike and walk more, said John Pucher, an urban design professor at Rutgers.

Biking and walking account for half of all urban trips in the Netherlands, a third of German trips, but less than a tenth of all trips in American cities, the study said.

One reason: Europe makes such trips easy but America makes them difficult, Pucher said.

Urban planners think Americans can lose some of their love of the internal combustion engine and get around more under their own steam. "People are beginning to understand why it is so important," said Julie Mercer Matlick, a community program manager with the Washington state Department of Transportation.
