Experts urge screening for obesity in kids

NEW YORK - Doctors should screen children and teens between 6 and 18 years for extra pounds, a federal task force recommends.

For children who are found to be obese based on their body mass index (BMI), a standard measure of the relationship between height and weight, the task force also calls for referrals to a comprehensive program that includes dietary advice, physical activity, and behavioral counseling to promote weight loss.

The new recommendations update earlier ones from 2005. Skyrocketing rates of obesity have reached between 12 and 18 percent in 2- to 19-year-olds, increasing up to 6-fold since the 1970s, members of the United States Preventive Services Task Force report in the February issue of the journal Pediatrics. Obesity is linked to the early development of diabetes and high blood pressure.

For their update, the task force reviewed 13 studies of behavioral intervention in 1258 obese children and adolescents.

Moderate- to high-intensity programs, involving more than 25 hours of contact with the child and/or the family over a six-month period, resulted in a decrease in BMI 12 months after the beginning of the intervention.
