We’re facing an epidemic of childhood obesity, and this could very well be a generation of children who live shorter, less healthy lives than their parents. A healthier transportation system for America’s kids requires change in federal policy. But change will remain out of our grasp without a sense of urgency from everyday people on the ground. So where’s the meeting point between policymakers in Washington and citizens in their neighborhoods?

Obesity is on the rise in 28 states and one of the biggest public health challenges facing America, but boosting walking and biking could help turn the tide. That is the conclusion of “F as in Fat: How Obesity Threatens America’s Future 2010.”

The Patient Protection and Affordable Care Act signed by President Obama earlier this year was a down payment on expanding health coverage and lowering costs. But the work does not stop there. A truly comprehensive approach to health must account for transportation’s role in how we move and our levels of physical activity. The American Public Health Association tackles just that in a new report titled “the Hidden Health Costs of Transportation.”

Earlier this month, we highlighted two reports on the integral link between health and transportation. First Lady Michelle Obama’s recent Let’s Move report on childhood obesity goes one step further — endorsing a new surface transportation bill that encourages more walking and biking.

A top priority in the transportation debate is addressing the mobility needs of the 56 million residents of rural areas and small towns in America – about 20 percent of the population of the United States. Rural areas and small towns often fall through the cracks of federal transportation policy, which focuses on statewide priorities for building new highways and often overlooks local needs and preferences. Transportation for America has been working closely with our coalition partners on this important issue for some time. Now, it looks like Secretary of Transportation Ray LaHood is also getting on board.

With Congress directing their attention to the contentious debate over health care reform and how to pay for it, it seems that transportation has been relegated to the back burner. In the meantime, evidence is continuing to mount that transportation investments — what we build and where — have an enormous impact on our health and the financial bottom line of providing health care. Two new studies add to a compelling case…

It’s not too difficult to spot the connection between Americans’ worsening obesity problem and an overreliance on automobiles. (No Impact Man — Colin Beavan)
