According to a study led by researchers from the Johns Hopkins Bloomberg School of Public Health, whether you believe the keys to combating childhood obesity are personal factors such as individual behavior changes or system-level factors such as marketing and the environment may depend on your primary news source.
Researchers examined the news media's framing of childhood obesity and found that television news was more likely than other news sources to focus on individual behavior change as a solution, while newspapers were more likely to identify system-level solutions. The results are featured in the June 20, 2011, issue of Pediatrics.
"Overall, news stories consistently mentioned behavior change most often as a solution to the problem of childhood obesity, however, we identified noticeable differences in coverage by source. Newspaper articles more often mentioned changes affecting neighborhoods, schools and the food and beverage industry, while television coverage often focused on individual child or parent behavior-oriented solutions," said Colleen Barry, PhD, MPP, lead author of the study and an associate professor with the Bloomberg School's Department of Health Policy and Management. "News media coverage patterns indicated that by 2003, childhood obesity was firmly on the news media's agenda, remaining so until 2007."
Barry, along with colleagues from Sarah Lawrence College, Yale School of Public Health and the University of Minnesota, analyzed the content of a random sample of news stories on childhood obesity published in 18 national and regional news sources in the U.S. from 2000 to 2009. Researchers measured whether a news story mentioned any potential solutions to the problem of childhood obesity and coded individual behavior change as well as system-oriented solutions such as changes affecting schools, neighborhoods and food and beverage industry practices to combat obesity. Over the ten year study period, researchers found the mention of solutions involving restrictions on the food and beverage industry such as food and beverage taxes, vending machine restrictions and advertising regulations rose substantially in the early years of the study, but have declined sharply in recent years.
The most common individual-level solutions mentioned were behavior change related to diet (45%), such as parents serving their children more fruits and vegetables, and exercise (36%), such as making more time for family-oriented physical activities. Thirty-seven percent mentioned school-level changes as a solution to the problem like serving healthy school lunches and requiring gym or recess. Few news stories mentioned neighborhood-level changes such as creating safe places for children to play or moving more grocery stores with healthy food options into poorer communities.
"Given that a majority of Americans obtain health information from the news media, how the news media frames the problem of childhood obesity will likely influence citizens' opinions about the types of private or governmental responses that are appropriate for addressing this global epidemic," said Sarah Gollust, PhD, senior author of the study and assistant professor in the Division of Health Policy and Management at the University of Minnesota. "Considering the movement toward consumer-oriented health care, the public increasingly relies on news media to obtain health information, challenging journalists to provide a fuller picture of the causes of childhood obesity and available options to combat it."
"We also found a decline in coverage of childhood obesity by the news media over the last few years. This decline would make sense if media attention had led to greater public awareness, and greater public awareness had led to a decline in obesity rates," Barry adds. "However, studies show that childhood obesity rates show no signs of declining. Thus, it is perhaps troubling that our results indicate reduced news media attention to the issue in the absence of having identified and implemented effective strategies for reducing childhood obesity rates."

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
