(Press-News.org) CHAMPAIGN, Ill. — Social safety net programs that reduce psychosocial stressors for low-income families also ultimately lead to a reduction in childhood obesity, according to research by a University of Illinois economist who studies the efficacy of food assistance programs on public health.
Craig Gundersen, a professor of agricultural and consumer economics at Illinois, says food and exercise alone are not to blame for the extent of obesity among children in the United States. Psychosocial factors, such as stressors brought about by uncertainty about the economy, income inequality, and a fraying social safety net also must be considered, he says.
"Energy-in, energy-out is important, but energy imbalance isn't the only thing leading to overweight status among children," said Gundersen, the executive director of the National Soybean Research Laboratory at Illinois. "We also know that people have very different ways of responding to the same amount of food intake and exercise, and one of the factors that may influence how people react to eating and exercise is through the amount of stress they're under."
Gundersen says stressors are particularly prevalent for low-income children, a demographic group that has high rates of obesity in the U.S. and other developed countries.
"As a society, we're always looking for different ways we can address public health issues, whether it's reducing food insecurity or reducing obesity," he said. "Although there have been many different ways to reduce obesity, what we've found is that stress is a leading cause of obesity among children. So if there's any way we can reduce stressors from a policy standpoint, that will also have the effect of reducing obesity."
The calls for trimming the social safety net that are currently in vogue in Washington, D.C., as part of a larger program of government austerity would likely lead to more obesity over time because it places more stress on low-income families, Gundersen says.
"If we cut back on benefits for the Supplemental Nutrition Assistance Program, or otherwise reduce its availability to people, that would increase the amount of stress that low-income families would face, which would then subsequently lead to increases in obesity," he said.
According to Gundersen, programs such as SNAP play a vital role in the social safety net as well as in efforts to end obesity.
"I really cannot stress how great of a program SNAP is," he said. "It's a fantastic program, and I think it can do a lot to help in our fight against obesity as it's currently constructed."
But there have been calls to restrict what SNAP recipients can purchase. For example, New York City recently proposed prohibiting children from purchasing sports drinks with their SNAP benefits. Gundersen views this development as setting a "dangerous precedent."
"Ultimately, placing restrictions on what people can buy only discourage them from participating in the program because it stigmatizes the benefits," he said. "The best way to reduce obesity isn't to introduce more restrictions, but to expand SNAP as it's currently structured."
Since SNAP allows families to purchase more healthy foods that they would otherwise be able to, any further restrictions or cutbacks to the program would have a two-fold effect, Gundersen says.
"Reducing access to SNAP would increase stress, which leads to increases in obesity, but it also means that families wouldn't be able to afford healthy foods and would subsequently have to purchase less healthy foods," he said. "When thinking about these sort of policy considerations, we have to think about who bears the brunt of these cutbacks, because not only could they lead to more obesity, but also to more inequality."
Gundersen says that while many families who are facing tough times may not be eligible for SNAP, which is only available to those below 130 percent of the poverty line, private food assistance networks can also play a key role in helping reduce food-scarcity stress.
"People know that if they're short on funds at the end of the month, they can go to their local food pantry and get some food," he said. "So a lot of people may be ineligible for SNAP but are still facing a very a stressful financial situation. Food banks really help those people, which in turn lowers stress and, by extension, obesity."
As many families face financial hardship as a result of the sluggish economy, Gundersen says that public policymakers need to be aware of the relationship between stressors and childhood obesity, which has only become more pronounced as income-inequality has grown over the last three decades.
"If present trends of income inequality are maintained, and if people are stressed by this – and there is some evidence to suggest that they are, to the extent that it's your position versus others in society, and not your absolute level of income – that, too, could lead to more obesity," Gundersen said.

Executive pay reform unlikely to reduce systemic risk in economy
2011-07-22
CHAMPAIGN, Ill. — Reforms aimed at curbing executive compensation will likely have little effect on reducing systemic risk in the financial system, and they may even have unintended consequences for the freedom to contract, according to a University of Illinois expert in business law and corporate finance.
In a paper published in the Ohio State Entrepreneurial Business Law Journal, law professor Christine Hurt argues that giving regulators unprecedented power to prohibit certain types of private compensation under the guise of minimizing systemic risk in the financial ...
Study: Regulatory hurdles hinder biofuels market
2011-07-22
CHAMPAIGN, Ill. — Regulatory hurdles abound for the successful commercialization of emerging liquid biofuels, which hold the promise of enhancing U.S. energy security, reducing greenhouse gas emissions and serving as a driver for rural economic development, according to new U. of I. research.
In the study, University of Illinois law professor Jay P. Kesan and Timothy A. Slating, a regulatory associate with the University of Illinois Energy Biosciences Institute, argue that regulatory innovations are needed to keep pace with technological innovations in the biofuels industry.

Chance favors the concentration of wealth, U of M study shows
2011-07-22
Most of our society's wealth is invested in businesses or other ventures that may or may not pan out. Thus, chance plays a role in where the wealth of a society will end up.
But does chance favor the concentration of wealth in the hands of a few, or does it tend to level the playing field? Three University of Minnesota researchers have built a simplified model that isolates the effects of chance and found that it consistently pushes wealth into the hands of a few, ever-richer people.
The study, "Entrepreneurs, chance, and the deterministic concentration of wealth," ...
NASA sees Tropical Storms Bret and now Cindy frolic in North Atlantic
2011-07-22
Two tropical storms are now in the open waters of the North Atlantic: Bret and Cindy. Both were captured on one image from NASA today. Both storms are hundreds of miles to the east-northeast of Bermuda and pose no threat to land areas.
NASA's GOES Project issued an infrared image of both Bret and Cindy today from the GOES-13 satellite, which is operated by NOAA. The NASA GOES Project is housed at NASA's Goddard Space Flight Center in Greenbelt, Md. and uses GOES-13 data from NOAA to create images and animations. The image was captured at 0845 UTC (4:45 a.m. EDT) and shows ...
MIT: Inside the innards of a nuclear reactor
2011-07-22
CAMBRIDGE, Mass. -- As workers continue to grapple with the damaged Fukushima Daiichi nuclear powerplant in Japan, the crisis has shone a spotlight on nuclear reactors around the world. In June, The Associated Press released results from a yearlong investigation, revealing evidence of "unrelenting wear" in many of the oldest-running facilities in the United States.
That study found that three-quarters of the country's nuclear reactor sites have leaked radioactive tritium from buried piping that transports water to cool reactor vessels, often contaminating groundwater. ...
Is anesthesia dangerous?
2011-07-22
In pure numerical terms, anesthesia-associated mortality has risen again. The reasons for this are the disproportionate increase in the numbers of older and multimorbid patients and surgical procedures that would have been unthinkable in the past. This is the result of a selective literature review of André Gottschalk's working group at the Bochum University Hospital in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108[27]: 469-74).
In the 1940s, anesthesia-related mortality was 6.4/10,000. By introducing safety standards such as pulse ...
Grazing management effects on stream pollutants
2011-07-22
MADISON, WI, JULY 21, 2011 -- Surface water quality is important for the proper function of aquatic ecosystems, as well as human needs and recreation. Pasturelands have been found to be major sources of sediment, phosphorus and pathogens in Midwest surface water resources. While poor grazing management may lead to contaminated surface water, little is known about the specific amount of pollution in pasture streams that can be attributed to grazing cattle.

Elimination of national kidney allocation policy improves minority access to transplants
2011-07-22
A new study published in the American Journal of Transplantation reveals that since the elimination of the kidney allocation priority for matching for HLA-B on May 7, 2003, access to kidney transplantation for minorities has been improved. Improvement is a result of a policy that reduced the requirements for tissue matching.
Prior national kidney allocation rules provided priority to candidates who shared HLA-B antigens with potential deceased donors. On May 7, 2003, allocation priority for HLA-B matching was eliminated. Improvements in medications used to prevent transplant ...
Researchers stumble on colorful discovery
2011-07-22
Modified metals that change colour in the presence of particular gases could warn consumers if packaged food has been exposed to air or if there's a carbon monoxide leak at home. This finding could potentially influence the production of both industrial and commercial air quality sensors.
"We initially found out by accident that modified rhodium reacts in a colourful way to different gases," says Cathleen Crudden, a professor in the Department of Chemistry. "That happy accident has become a driving force in our work with rhodium."
Rhodium that is modified using carbon, ...
UCI-led butterfly study sheds light on convergent evolution
2011-07-22
Irvine, Calif., July 21, 2011 – For 150 years scientists have been trying to explain convergent evolution. One of the best-known examples of this is how poisonous butterflies from different species evolve to mimic each other's color patterns – in effect joining forces to warn predators, "Don't eat us," while spreading the cost of this lesson.
Now an international team of researchers led by Robert Reed, UC Irvine assistant professor of ecology & evolutionary biology, has solved part of the mystery by identifying a single gene called optix responsible for red wing color ...
