Just two hours of extra physical activity each week can improve school performance. This has been shown by a study of approximately 2,000 12-year-olds carried out by scientists at the Sahlgrenska Academy, University of Gothenburg [in Sweden].
Researchers Lina Bunketorp Käll, Michael Nilsson, and Thomas Linden at the Centre for Brain Repair and Rehabilitation at the Sahlgrenska Academy, tested the hypothesis that increased physical activity stimulates learning and improves school performance. Continue reading

Infants who quickly add weight and length may be showing a genetic propensity for obesity as toddlers, a new study suggests.
In adults, certain genes have been linked to increased body fat, but the same genes in infants promote proportionate gains in fat and lean muscle, the researchers said. Continue reading

There are noticeable differences in the shape and function of hearts among obese and normal-weight adolescents, researchers say.
“We do not know if (these changes) are clinically meaningful or necessarily dangerous,” said Dr. Norman Mangner of the University of Leipzig Heart Center in Germany. “This is a cross-sectional study and, therefore, we cannot answer this question.” Continue reading

On Oct. 17 the U.S. Department of Agriculture (USDA) awarded $4 million in grants to establish four regional centers of excellence for research on nutrition education and obesity prevention, as well as a coordinating center, which will develop and test innovative nutrition education and obesity prevention interventions for underserved, low-income families.
“Nearly one in three children today is overweight or obese, and nutrition promotion strategies, including education, public policies, health systems, and environmental changes, are the key to reversing this trend,” said Sonny Ramaswamy, Ph.D., National Institute of Food and Agriculture (NIFA) director. “These grants provide the opportunity to improve the health of our next generation and ensure that all children have access to the tools they need to improve their nutrition and physical fitness.” Continue reading

Gourmet pizza in school? According to a new Food and Brand Lab pilot study, published in Appetite, chef-made meals can increase participation in the National School Lunch Program (NSLP) by 9 percent and overall selection and consumption of vegetables by 16 percent.
Chefs Move to Schools (CMTS), an initiative of [first lady] Michelle Obama’s Let’s Move! campaign, pairs chefs with schools in order to provide nutrition instruction to students and culinary advice to interested school food service workers.
At a recent CMTS event at an Upstate New York high school (of 370 students), researchers David Just and Brian Wansink (co-directors of the Cornell University Food and Brand Lab) and Andrew Hanks [also of the Cornell lab], collected and analyzed school lunch sales and tray waste data before and after the event to determine its impact on student’s food selection and consumption.

Rates of adult obesity increased in six U.S. states and fell in none last year, and in more states than ever— 20— at least 30 percent of adults are obese, according to an analysis released on Sept. 4.
The conclusions were reported by Trust for America’s Health (TFAH) and the Robert Wood Johnson Foundation and were based on federal government data. They suggest the problem may be worsening despite widespread publicity about the nation’s obesity epidemic, from first lady Michelle Obama and many others, plus countless programs to address it.
From 2011 to 2012, by comparison, the rate of obesity increased in only one state.
The 2013 adult obesity rate exceeds 20 percent in every state, while 42 have rates above 25 percent. For the first time two states, Mississippi and West Virginia, rose above 35 percent. The year before, 13 states were above 30 percent and 41 had rates of at least 25 percent. Continue reading

When confronted with an overly active child, many exasperated teachers and parents respond the same way: “Sit still!” It might be more effective, though, to encourage the child to run. Recent research suggests that even small amounts of exercise enable children to improve their focus and academic performance.
By now it’s well known that diagnoses of attention deficit hyperactivity disorder (ADHD) are increasingly widespread among American children: The label has been applied to about 11 percent of those between the ages of 4 and 17, according to the latest federal statistics. Interestingly, past studies have shown a strong correlation between greater aerobic fitness and attentiveness. But these studies did not answer the question of which comes first, the fitness or the attentional control. Continue reading

A simple, family meal each day may reduce the risk of obesity in teens. Scientists have found that family meals during adolescence were protective for overweight and obesity in adulthood.
In order to see whether family meals played a role in obesity reduction, the scientists used data from a 10-year longitudinal study. They examined weight-related variables, such as dietary intake, physical activity, and weight control behaviors among adolescents. Then the scientists asked questions to assess family meal frequency and body mass index.
About 51 percent of the subjects were overweight while 22 percent were obese. More surprising though was the rate seen among adolescents who never ate family meals together; 60 percent were overweight and 29 percent were obese at a 10-year follow-up. There was also a stronger positive effect when it came to family meal frequency among black young adults compared with white young adults. Continue reading
The Global Obesity Prevention Center (GOPC) at Johns Hopkins invites you to attend a day-long symposium titled “The Social Network: A Systems Approach to #ChildhoodObesity.” The event will be Oct. 22, 2014, from 8 a.m. to 5:45 p.m. at the Johns Hopkins Bloomberg School of Public Health in Baltimore, Md.
The past decade has seen increasing interest in social networks, i.e., how people are connected to their families, friends, school mates, and work colleagues. These relationships affect what, where, and how children eat and exercise, and in turn, the risk of obesity. Continue reading
