Updated American Academy of Pediatrics guidelines for treatment of obesity urge prompt use of behavior therapy and lifestyle changes, and they say surgery and medications should be used for some young people.

The guidelines, published Monday in the journal Pediatrics, are the first comprehensive update to the academy’s obesity treatment guidelines in 15 years. They provide guidance for treatment of children as young as 2 and through the teen years.

The guidelines acknowledge that obesity is complex and tied to access to nutritious foods and health care, among other factors.

Treatment for younger children should focus on behavior and lifestyle treatment for the entire family, including nutrition support and increased physical activity. For children 12 and older, use of weight loss medications is appropriate, in addition to health behavior therapy and lifestyle treatment, the academy says. Teens 13 and older with severe obesity should be evaluated for surgery, according to the guidelines.

“There is no evidence that ‘watchful waiting’ or delayed treatment is appropriate for children with obesity,” Dr. Sandra Hassink, an author of the guideline and vice chair of the group’s Clinical Practice Guideline Subcommittee on Obesity, said in a statement. “The goal is to help patients make changes in lifestyle, behaviors or environment in a way that is sustainable and involves families in decision-making at every step of the way.”

For children and teens, overweight is defined as a body mass index at or above the 85th percentile and below the 95th percentile; obesity is defined as a BMI at or above the 95th percentile.

Myles Faith, a psychologist at the State University of New York at Buffalo who studies childhood eating behaviors and obesity, praised the new report for acknowledging that the causes of childhood obesity are complex and that its treatments must be a team effort.

“It’s not one cause for all kids,” he said. “There’s not been this kind of report to say that there are more options and that we shouldn’t automatically discount the possibility of medication, that we shouldn’t discount the role of surgery. For some families, it might be something to consider,” said Faith, who was not involved in the creation of the guidelines.

The new guidelines do not discuss obesity prevention; it will be addressed in another policy statement to come, the American Academy of Pediatrics says.

“These are the most comprehensive, patient-centered guidelines we have had that address overweight and obesity within childhood,” Dr. Rebecca Carter, pediatrician at the University of Maryland Children’s Hospital and assistant professor at the University of Maryland School of Medicine, said in an email Monday.

“New to these recommendations are several new medication management strategies that have proven very successful in the treatment of obesity as a chronic disease for adults, and are now being recommended for use in children and adolescents,” Carter wrote. “This is a major step in allowing overweight and obesity to be considered as the chronic diseases that they are.”
