Public Health

The Robert Wood Johnson Foundation launched their "New Public Health" website last year with the goal of meeting community members where they are to talk about public health. A lot of those conversations happen online, and they explore the connections between public health and policy decisions related to everything from education to transportation. Last week, they published an interview with U.S. DOT Secretary Ray LaHood.

On Thursday, DOT Secretary Ray LaHood announced the creation of a new Freight Policy Council, which is charged with coming up with a freight strategic plan. This is a first step toward a sorely lacking national plan around freight.

Transportation projects often have profound consequences for public health, whether negative (in the case of fossil fuel-burning highway expansions) or positive (in the case of calorie-burning bike-friendly, walkable streets). So why don't cities and states always consider health impacts when evaluating a transportation project or policy?

Sidewalks, bike lanes, traffic calming projects -- they save lives. Not just by protecting cyclists and pedestrians (not to mention motorists), but by encouraging physical activity that leads to a healthy life.

One of the most talked-about presentations at this week's National Bike Summit came from Jason Gaikowski, director of sales for the Bloomington, Minnesota-based wholesale distributor Quality Bicycle Products. Over the last several years, QBP has ramped up its employee health and wellness program, which includes incentives to bike to work. At a time when most employers are grappling with rising insurance premiums, a study by the company's health insurance provider, HealthPartners [PDF], suggests the program has helped reduce QBP's health care costs and increase employee productivity.

"A leading voice for better urban design for the sake of good health." "A public health/social justice hero." Dr. Richard Jackson, chair of environmental health at UCLA, is a leading voice for transportation reform whose work has linked America's sprawl to the nation's high rates of obesity.

Check out these two maps, the first showing obesity rates (by county) in the United States and the second showing the percentage of commuters who travel by car (via Planetizen).

Gerontologists in a laboratory at the University of Southern California exposed a group of mice to the same atmospheric conditions that humans encounter when driving along the freeway. Horrifyingly, they discovered that the mice’s brains showed the kind of swelling and inflammation associated with diseases such as Alzheimer’s. The researchers didn’t super-dose to get these results: the mice were exposed to freeway air for the equivalent of 15 hours a week -- less than the 18.5 hour average Americans spend in their cars. Jokes aside about getting those darn mice off the road, the study suggests that driving less can reduce our risk of brain damage.
