Obesity screening recommended for kids

On January 25, 2010, in Uncategorized, by Andrea

It’s a sad fact — and one that as a parent I must accept — that our kids are becoming obese at a rate that is outpacing even our expectations as an obese nation.

I imagine that some screening is already in place by some pediatricians.  I know that our normal pedi doesn’t do blood pressure checks, but our specialist pediatrican’s office (we go to a GI and allergist) does do BP checks.  Perhaps this should be done by a general pedi as well?

What about A1c and cholesterol screening?  At what point does cost outweigh risk factors?

USPSTF Recommends Obesity Screening for Children Ages 6 to 18 Years

Laurie Barclay, MD

January 22, 2010 — The US Preventive Services Task Force (USPSTF) recommends that clinicians screen children ages 6 to 18 years for obesity and refer as appropriate to programs to improve their weight status, according to evidence-based guidelines posted online January 18 and to be published in the February print issue of Pediatrics. The statement, which is an update of the 2005 USPSTF statement about screening for overweight in children and adolescents, is accompanied by a supporting systematic review and commentary.

“Since the 1970s, childhood and adolescent obesity has increased three- to sixfold,” write chair Ned Calonge, MD, MPH, from the Colorado Department of Public Health and Environment in Denver, and colleagues from the USPSTF. “Approximately 12% to 18% of 2- to 19-year-old children and adolescents are obese (defined as having an age- and gender-specific BMI [body mass index] at >95th percentile)….Previously, the USPSTF found adequate evidence that BMI was an acceptable measure for identifying children and adolescents with excess weight.”

The USPSTF evaluated evidence for the efficacy of pediatric weight management interventions that are feasible in primary care or referable from primary care. The task force also considered the evidence for the magnitude of potential harms of treatment in children and adolescents.

This evidence led the USPSTF to issue a grade B recommendation that clinicians screen children 6 years and older for obesity and provide obese children with intensive counseling and behavioral interventions designed to improve weight status, or that they refer them for such counseling and interventions.

During health maintenance visits, height and weight are routinely measured, allowing calculation of BMI. Based on a review of 20 clinical trials of behavioral and pharmacologic interventions for obesity, the task force concluded that evidence was adequate that comprehensive, moderate- to high-intensity interventions effectively improve BMI in children.

“Over the past several years, research into weight management in obese children and adolescents has improved in quality and quantity,” write Evelyn P. Whitlock, MD, MPH, from the Center for Health Research, Kaiser Permanente in Portland, Oregon, and colleagues. “Despite important gaps, available research supports at least short-term benefits of comprehensive medium- to high-intensity behavioral interventions in obese children and adolescents.”

Moderate- to high-intensity programs are defined as those in which there are more than 25 hours of contact with the child and/or family during a 6-month period. Low-intensity interventions were not associated with significant improvement in weight status.

Three components needed for effective, comprehensive programs are counseling regarding healthy diet and/or weight loss; counseling regarding physical activity recommendations or a physical activity program; and behavioral management techniques including setting goals and self monitoring.

Families seeking treatment for obese children should therefore consider comprehensive programs targeting weight control through healthy food choices, physical exercise, and building behavioral skills.

The task force also concluded that evidence is adequate that the harms of behavioral interventions are no greater than small, and that there is moderate certainty that the net benefit is moderate for screening for obesity in children at least 6 years old and for offering or referring children to moderate- to high-intensity interventions to improve weight status. The USPSTF did not find sufficient evidence for screening children younger than 6 years.

Although interventions that combined pharmacotherapy (sibutramine or orlistat) with behavioral interventions were associated with modest short-term improvement in weight status in children at least 12 years old, there were no long-term data on maintenance of improvement after medications were discontinued. The magnitude of the harms of these medications in children could not be estimated with certainty, but known adverse effects include elevated heart rate and blood pressure and adverse gastrointestinal tract effects.

“Areas for further research include investigations to determine the specific effective components of behavioral interventions,” the task force concludes. “Longer-term follow-up of participants in behavioral or multicomponent trials is needed to confirm maintenance of treatment effect and to assess longer-term risks and harms. Investigation is needed of more efficient, primary care–feasible interventions that use allied health professionals. More studies are needed that address weight management in minority children and adolescents, behavioral interventions in younger children (aged <5 years), and behavioral interventions in children who are overweight but not obese.”

In an accompanying commentary, pediatrician and American Academy of Pediatrics Board of Directors member Sandra Hassink, MD, FAAP, from A. I. Dupont Hospital for Children in Wilmington, Delaware notes that the American Academy of Pediatrics supports the USPSTF recommendations but also recommends routine obesity screening of children beginning at age 2 years.

“Recognition that screening is the first step to individual evaluation and counseling for obesity prevention and treatment should be standard in practice now,” Dr. Hassink writes. “Working with families to screen for high-risk nutrition and activity behaviors that contribute to obesity in early childhood must be part of that task. With that said, the current USPSTF report is significant because it provides evidence that obesity treatment can be effective and extend beyond the immediate intervention and that pediatricians in the context of a medical home model that supports multidisciplinary care, with the appropriate supports of training and reimbursement, can provide effective obesity prevention and treatment for the families and children in their care.”
