Same genes linked to rapid infant growth, later weight gains

Oct. 21, 2014, HealthDay

By Steven Reinberg

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

With extra weight, kids’ hearts change shape

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

Chef-made meals can increase participation school lunch program, raise vegetable consumption

Sept. 30, 2014, News Medical

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.

Obesity rates reach historic highs in more U.S. states

Sept. 4, 2014, Reuters

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

Put the physical in education

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

Family meals could protect teens from obesity in adulthood

Oct. 4, 2014, Science World Report

By Catherine Griffin

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

Researchers: Link between repeated antibiotic use in early childhood and obesity

Sept. 30, 2014, The Washington Post

By Ariana Eunjung Cha

When a parent carrying a screaming toddler with a middle-ear infection or other common ailment shows up, many pediatricians instinctively reach for their prescription pads. Despite warnings about the risk of resistance, antibiotics remain one of the most frequently used weapons in routine care. But now doctors have another reason to be cautious: the risk of obesity.

In a study published online Sept. 30 by JAMA Pediatrics, researchers reviewed records from about 65,000 children from 2001 to 2013 and found that almost 70 percent received antibiotics before age 2. On average, each child received 2.3 courses. Continue reading

Gap in diet quality between wealthiest and poorest Americans doubles, study finds

Sept. 1, 2014, National Geographic

By Tracie McMillan

The diets of low-income Americans have worsened in the past decade, even as the diets of the wealthiest Americans have improved, according to a new study that is among the first to measure changes in diet quality over time by socioeconomic status. Overall diet quality in the United States remains poor, said the lead author of the study, published Sept. 1 in the Journal of the American Medical Association Internal Medicine.

Although the study found that the diet of all Americans improved on average between 2005-2010, the progress masked a decline in diet quality among the poor. The result: a doubling of the gap in diet quality between the wealthiest Americans and the poorest.

The study attributed the change to the higher cost of convenient and healthy meals, as well as limited access to quality supermarkets in some poorer neighborhoods. Continue reading

USDA backs healthy incentives

Oct. 6, 2014, U.S. Department of Agriculture

USDA is firmly committed to ensuring that all Americans have access to a safe, healthy, adequate, and affordable diet. Unfortunately, our nation is facing an unprecedented nutrition crisis, with far too many Americans facing both food insecurity and obesity. Although it seems paradoxical, the two actually go hand in hand far too often. To reverse the course of this two-sided crisis, we must create a cultural change that facilitates and encourages healthy food choices among all Americans.

After-school exercise yields brain gains

Sept. 29, 2014, HealthDay

By Tara Haelle

Regular daily exercise appears to improve children’s attention and multitasking skills, according to a new study.

Elementary school-age students who participated in an after-school program with plenty of physical activity showed greater improvements in several areas of so-called “executive function” than similar students who did not participate.

Executive function refers to a range of mental or “cognitive” skills that include memory, focus, attention, and the ability to switch back and forth between tasks.

Lead researcher Charles Hillman said that students who had the highest attendance in the program saw the biggest gains in mental skills. Continue reading
