In an effort to combat rising rates of childhood obesity, the Robert Wood Johnson Foundation announced Wednesday that it would commit at least $500 million over the next five years to tackle the problem.
The announcement means that more money than ever will be spent to try to reverse the epidemic of childhood obesity in the United States -- a goal that the foundation hopes to achieve by 2015.
The effort may not come a moment too soon. Today in the United States, about 25 million kids -- more than 33 percent of the country's children and adolescents -- are either overweight or at risk of becoming overweight.
The grant money is available to anyone with a good idea on how to curb the trend. Ideas on lifestyle modification, facilities for physical activity and school nutrition programs have already been proposed.
And the grant will focus on reaching kids and families in underserved communities -- in many ways, the epicenter of the nation's childhood obesity problem.
But even the foundation's officers say that $500 million is only a start when it comes to solving the growing crisis of kids who eat far too much -- and exercise far too little.
"This is the largest commitment we've ever made as a foundation," says Dr. James Marks, senior vice president and director of health programs for the Robert Wood Johnson Foundation.
"But large as that is, we know it's not enough."
Depending on how it is spent, health experts say the money could have a giant initial impact.
"It's a huge potential," says Keith Ayoob, associate professor in the department of pediatrics at the Albert Einstein College of Medicine in New York City. "But it's going to be a tool, and like any tool, it can be used wisely or squandered."
Ayoob says it will be critical that the money is not used on only institutional programs but also on programs aimed at parents that ensure healthy lifestyle choices for children in their home environments.
But considering the sheer scope of the problem, some public health experts say half a billion may just represent a healthy start.
"I think that given the magnitude of the problem and how pervasive it is worldwide, we need more investment in this than just $500 million," says Robert Jeffrey, professor of epidemiology at the University of Minnesota's division of epidemiology and community health.
Marks says he hopes the move will be seen as a catalyst -- one that will spur other philanthropic groups, government institutions and individuals to action.
"What we hope is that it changes the landscape and that others, such as government and private industries, will recognize this problem," he says.
Considering the amount of attention that the threat of childhood obesity has already received, the move will likely garner many allies, Ayoob says.
"I think the chances for working together against this problem are pretty good, because already we have seen the rumblings of that," he says. "I see this as a start, and I hope that it is a catalyst for action."
Still, with millions of children already experiencing the health effects of overweight and obesity, efforts to turn the tide may be off to a woefully late start.
"I'd like to be optimistic, but right now we've got a long way to go," Jeffrey says. "We live in a country in which both the environment and culture is hooked on overeating.
"I think that, as a culture, we are largely in denial on this."
