The less-than-perfect results underscore the challenge in fighting the nation's obesity epidemic. About 34 percent of American children are overweight.
A team led by researchers at Washington University School of Medicine in St. Louis found that obese children who lost weight kept it off if they were in a maintenance program, but its effectiveness waned over time.
The research involving 150 overweight 7- to 12-year-olds is one of the first large-scale studies to evaluate the long-term effect of weight-loss maintenance strategies in children.
The study, which appeared in Wednesday's Journal of the American Medical Association, also is the first to look at whether heavy kids benefited from being encouraged to play with more physically active peers, cope with teasing, and develop an improved body image.

The researchers studied obese youngsters from 1999-2004 at a university clinic in San Diego, where Wilfley used to teach. The children weighed at least 65 percent more than their recommended weight. All of the children in the study also had at least one parent who was overweight.
Each child and parent went through a five-month weight-loss program that set goals, emphasized healthy eating and exercise. They were also counseled by behavioral therapists. On average, after five months, the children lost about 11 percent of their weight.
They were then randomly assigned to one of three groups for four months.
One group was given no further instruction. Another group focused on self-monitoring, vigilance and used other behavior skills, trying to lose weight right away if they regained it.
In the third group, the youngsters were guided into play dates that involved physical activity and healthy eating; they were encouraged to make friends with more physically active peers. They also were counseled on body image and how to cope with teasing.
Researchers checked progress after one year and again after two years.
Those in the behavior skills and social groups were better able to keep weight off in the short term than the kids who had no intervention. However, those effects waned somewhat during follow-up. The kids left to their own devices regained their lost pounds, and then some, after two years.
