NIH Disses Physical Activity as Cure of Childhood Obesity

November 23rd, 2011

The National Heart, Lung and Blood Institute has issued guidelines endorsed by the American Academy of Pediatrics. They are directed to all primary pediatric care providers to address the known risk factors of cardiovascular disease, including obesity, blood pressure, cholesterol, tobacco and lipids.

The report notes that longitudinal data on non-white populations are lacking and that “Clinically important differences in prevalence of risk factors exist according to race and gender, particularly with regard to tobacco-use rates, obesity prevalence, hypertension, and dyslipidemia.”

The report notes, “Obesity tracks more strongly than any other risk factor, among many reports from studies that have demonstrated this fact…Tracking data on physical data is more limited.”

Regarding overweight and obesity, the report states,

“The dramatic increases in childhood overweight and obesity in the United States since 1980 are an important public health focus. Despite efforts over the last decade to prevent and control obesity, recent reports from the National Health and Nutrition Examination Survey show sustained high prevalence: 17% of children and adolescents have a BMI at the >95th percentile for age and gender. The presence of obesity in childhood in childhood and adolescence is associated with increased evidence of atherosclerosis at autopsy and of subclinical measures of atherosclerosis on vascular imaging. Because of its strong association with many of the other established risk factors for cardiovascular disease, obesity is even more powerfully correlated with atherosclerosis; this association has been shown for BP, dyslipidemia, and insulin resistance in each of the major pediatric epidemiologic studies. Of all of the risk factors, obesity tracks most strongly from childhood into adult life.”

Given that physical activity is a primary prescription for preventing childhood and adolescent obesity, it is interesting to read what the expert panel has to say about its utility:

“A moderate number of RCTs (randomized controlled clinical trials) have evaluated the effect of interventions that addressed only physical activity and/or sedentary behavior on prevention of overweight and obesity. In a small number of these studies, the intervention was effective. It should be noted that these successful interventions often addressed reduction in sedentary behavior rather than attempts to increase physical activity. In a majority of these studies there was no significant difference in body-size measures. Sample sizes were often small and follow-up was often short (frequently < 6 months). ..Overall, the expert panel concluded that on the basis of the evidence review, increasing activity in isolation is of little benefit in preventing obesity. By contrast, the review suggests that reducing sedentary behavior might be beneficial in preventing the development of obesity.”

The report identifies populations at special risk for obesity: children with a BMI between the 85 and 95th percentiles;children in whom there is a positive family history of obesity in 1 or both parents; early onset of increasing weight; excessive weight gain during adolescence; children who have been very active and become inactive. See Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents- NHLBI, NIH

Better tools for Primary Care Providers

November 14th, 2011

The New England Journal of Medicine has just published a study by Thomas Wadden, et al., Three interventions were compared. One group received usual care consisting of quarterly visits with a primary care provider that included education about weight management. The second group received brief lifestyle counseling, consisting of quarterly visits with the primary care provider plus brief monthly session with lifestyle coaches who provided instruction about behavioral weight control. The third group received the same care as the second group but with the addition of meal replacements or weight-loss medications (orlistat or sibutramine before it was taken off the market). 

The percentage of participants who lost more than 5% of their initial weight was 21.5% in the usual-care group, 26% in the brief-lifestyle counseling group and 34.9% in the enhanced-brief counseling group. The change in weight loss at 24 months was -1.7 kg in usual-care group, -2.9kg  in the  brief-lifestyle group, and -4.6kg in the enhanced brief-lifestyle group. The pattern shows significant weight loss at 6 and 12 months with subsequent modest regain. Participants who received enhanced brief-lifestyle intervention saw significant reductions in cardiovascular risk factors. SeeA Two-Year Randomized Trial of Obesity Treatment in Primary Care Practice — NEJM

In a second article, Lawrence J. Appel and colleagues compared in-person support with remote care delivered without face-to-face contact between participants and weight loss coaches.  The percentage of participants who lost more than 5% of their initial weight was 18.8% in the control group, 38.2% in the remote support-only group and 41.4% in the in-person group. The change in weight loss was -0.8kg in the control group, -4.6kg in the remote-only group and -5.1kg in the in-person group, corresponding to -1.1%, -5% and -5.2%. Importantly, most participants sustained the weight loss at 24 months. Comparative Effectiveness of Weight-Loss Interventions in Clinical Practice — NEJM

See the Philadelphia Inquirer story by Don Sapatkin, Studies point to weight loss at the doctor’s office | Philadelphia Inquirer | 11/15/2011

Taken both together and with earlier research on primary care, the picture is that intervention by primary care providers can convey the seriousness of weight loss as well as provide patients with some real weight loss, albeit modest compared with surgery and some of the medications under review by the Food and Drug Administration but more than broad prescriptions to lose weight. Intensity matters as does the use of several, mutually-supporting strategies.

President Obama calls for health insurance reform to cover obesity treatments, stating, “All I’m saying is let’s take the example of something like diabetes, one of — a disease that’s skyrocketing, partly because of obesity, partly because it’s not treated as effectively as it could be. Right now if we paid a family — if a family care physician works with his or her patient to help them lose weight, modify diet, monitors whether they’re taking their medications in a timely fashion, they might get reimbursed a pittance. But if that same diabetic ends up getting their foot amputated, that’s $30,000, $40,000, $50,000 — immediately the surgeon is reimbursed. Well, why not make sure that we’re also reimbursing the care that prevents the amputation, right? That will save us money. Text – Obama’s Health Care Town Hall in Portsmouth – NYTimes.com
