Kids Who Feel Left Out Are Less Active

Feb. 6, 2012 -- Children who feel left out, even for a little while, may be less active.

A new study shows that kids who are ostracized by other children are more likely to choose non-active pastimes over physical ones.

The results showed that children who were excluded during an online computer game later spent 41% more minutes being sedentary, rather than choosing a more physical activity at a gym where they could pick any diversion they liked.

Researchers say it’s the first study to look at the effect of ostracism on physical activity in children.

“These findings are worrisome,” write researcher Jacob E. Barkley, PhD, of Kent State University, and colleagues in Pediatrics. “The lack of physical activity and engagement in sedentary behaviors in children and adolescents are concurrently and prospectively related to obesity and other health difficulties.”

Previous studies have already shown that ostracism increases eating. Researchers say these results suggest another possible way that ostracism may contribute to childhood obesity.

Smoking in Men Speeds Up Mental Decline

Feb. 6, 2012 -- Smoking is bad for the brain, especially for male smokers.

Men who smoke tend to have a more rapid mental decline than men who do not smoke, a new study shows. But the findings did not reveal a similar link between smoking and mental decline in female smokers.

Although the exact reason for the sex difference is unclear, one possibility is that women tend to smoke fewer cigarettes a day than men do and for fewer years. Other lifestyle habits, such as male smokers drinking more alcohol, may also account for some differences seen.

In the study, published in the Archives of General Psychiatry, scientists analyzed data from nearly 6,000 men and more than 2,100 women who were British civil servants. To evaluate their thinking abilities, participants were given their first mental assessment at midlife, an average age of 56.

The assessment included five tests of memory, vocabulary, and reasoning (verbal and math) skills. Participants were retested two more times (every five years) over a decade.

To determine volunteers' smoking habits over a 25-year period, researchers looked at their then-current smoking status and past history, including whether they had quit or relapsed.

Faster mental decline was seen in middle-age men who currently smoked than men who never did.

School Vending Machines Still Offer Too Many Sugary Snacks

Feb. 6, 2012 -- About half of elementary school students still have access to sugary snacks and other unhealthy options in school vending machines, according to a new study.

To combat rising childhood obesity rates, the Institute of Medicine recommended in 2007 that school meal programs be the primary source of nutrition in schools and called for limiting access to competitive foods in vending machines and other venues.

Despite these guidelines, researchers found that access to competitive foods did not change much in public or private elementary schools from 2006 to 2010.

More than half of elementary schools students, by 2010, could purchase foods from one or more sources in schools other than the school meal program, such as vending machines, school stores, or snack bars. Sugary foods were available to nearly all children with access to these options. Healthier options were less widely available.

“Because children spend many hours in school, changes are needed to make the school environment healthier by limiting the availability of less healthy food products,” researcher Lindsey R. Turner, PhD, of the Institute for Health Research and Policy at the University of Illinois at Chicago, and colleagues write in Archives of Pediatric and Adolescent Medicine.

In 2010, the Healthy, Hunger-Free Kids Act gave the U.S. Department of Agriculture the authority to set nutritional standards for all foods sold in schools. Current regulations state that foods of minimal nutritional value cannot be sold in the cafeteria during lunchtime, but they may be sold in vending machines in schools at any time.
