The study, published in The Journal of the American Medical Association, isn't about putting overweight children on a restrictive diet.
Instead, it's about building a healthy lifestyle for parents and kids alike.
"The parents were key. Parents were the major agent of change in the home," Yale University researcher Mary Savoye, RD, CD-N, CDE, told reporters.
Those changes, detailed in Savoye's study, took effort. But they paid off by helping overweight kids lose extra body fat, lower their risk of developing type 2 diabetes, and learn healthy lifestyle habits.
"The secret is it's an educational process," Savoye says. "My guess is they will continue to do well because now they can make informed decisions about better food choices."
Overweight Children
Americans of all ages, including children, are increasingly becoming overweight. Extra pounds make health problems, including diabetes and high blood pressure, more likely.
"Since an overweight child has a high probability of becoming an overweight adult, the grave concerns for the long-term health of obese children are well justified," Savoye's team writes.
Savoye and colleagues studied 209 overweight children aged 8 to 16 in inner-city New Haven, Conn.
First, the kids got a thorough checkup that included measuring their height, weight, blood pressure, and cholesterol. Next, the researchers randomly split the kids into two groups.
One group of kids was assigned to participate -- with a parent or caregiver -- in an intensive lifestyle program called Bright Bodies for one year.
The other group of children saw a doctor, dietitian, and social worker for checkups every six months and received counseling on nutrition and exercise.
Family Weight Control
Children and their caregivers in the Bright Bodies group attended sessions twice weekly for the first six months and twice monthly for the second six months.
In the sessions, they learned about nutrition, goal setting, self-awareness, and coping skills. The kids also got supervised group exercise sessions, which focused on making fitness fun.
Exercise included dancing, jumping rope, and playing basketball and flag football.
