Active Friends Help Kids Get Moving

If your child's BFF is active, that may have a positive impact on your own child's health. On the other hand, if your child's friends tend to be sedentary and have unhealthy eating habits, that could have a negative impact on your child's health. Why is that?

Sabrina Gesell, a research assistant professor in pediatrics at the Vanderbilt School of Medicine, and her colleagues, studied a network of friends in an after- school program involving students, ages 5 to 12. Using a pedometer-like device that recorded minute muscle movements, the researchers tracked kids's physical activity levels over a period of 12 weeks.

At the start of the program, none of the children knew one another well, so the researchers were able to track how the youngsters made and dropped friends and what effect these changing relationships had on their physical activity level.

They discovered that during the time the children spent in the program, the strongest factor influencing how much time they spent engaged in moderate to vigorous physical activity was the activity level of their four to six closest friends. In fact, children changed their exercise level about 10% to better match those in their circle; children who hung out with more active students were more likely to increase their physical activity levels, while those who befriended more sedentary children became less active.

We see evidence that the children are mirroring, emulating or adjusting to be similar to their friends,says Gesell. And that's exciting because we saw meaningful changes in activity levels in 12 weeks.

The results suggest a potentially inexpensive and effective way to change childrens behavior. Obesity is engulfing too many of our young kids, bringing with it adult diseases and shortened life spans. Scientists believe the results from this study may offer a new and easier way to help more kids get off the couch, and put down the sodas and chips. From a public- health perspective, that would mean seeding groups like after-school programs or community groups with children who like to exercise, so that by emulating them, others may become more active by association.

Even kids in day care can stand to benefit: a recent study found that children in day care are active only about 2% to 3% of the time they are there. Gesell says the results could help in providing a much needed new tool for confronting the obesity epidemic.

Gesell is eager to conduct the next phase of studies, which would break down exactly how large an influence a single active child can have on the behavior of his more sedentary classmates. Hers is not the first study to analyze the contagion effect of social networks. Previous studies have documented how a persons social network can influence everything from his likelihood of gaining weight or quitting smoking to levels of loneliness and happiness. However, Gesell is the first to study the phenomenon in children. This is a novel approach to obesity prevention,says Gesell. None of the approaches to combating obesity are really working now, and we need a new approach. The social environment does carry more power than we have given it credit for, so we should leverage that intentionally.

With social networking becoming such a huge influence in kid's daily lives, researchers suggest using these childhood networks to encourage exercise and perhaps other positive behaviors could help kids in the long run, by turning them into healthier adults.

The study was published in the journal Pediatrics
