Younger adolescents who underwent metabolic and bariatric surgery had outcomes similar to those of older adolescents undergoing the same procedure, according to recent research in Pediatrics.
Five years after metabolic and bariatric surgery (MBS), adolescents between ages 13 and 15 years had similar outcomes with regard to reduction in body mass index percentage, hypertension and dyslipidemia, and improved quality of life, compared with adolescents between ages 16 and 19 years, according to Sarah B. Ogle, DO, MS, of Children’s Hospital Colorado at the University of Colorado at Denver, Aurora, and colleagues.
“These results appear promising for the treatment of severe obesity in young patients,” Dr. Ogle and colleagues wrote, “however, further controlled studies are needed to fully evaluate the timing of surgery and extended long-term durability.”
The researchers analyzed the outcomes of adolescents enrolled in the Teen–Longitudinal Assessment of Bariatric Surgery who were aged 19 years or younger and underwent MBS between March 2007 and December 2011 at five U.S. centers. In the group of younger adolescents (66 participants), the mean age at surgery was 15.1 years, while the group of older adolescents (162 participants) had a mean age of 17.7 years at the time of surgery. Both groups consisted mostly of White (71.6%-72.7%) girls (72.7%-75.9%) who were morbidly obese (mean BMI, 52.4-53.1 kg/m2). With regard to baseline comorbidities, about three-quarters of participants in the younger (72.4%) and older (77.0%) adolescent groups had dyslipidemia. More than one-quarter of younger adolescents had hypertension (27.3%) compared with more than one-third of older adolescents (37.1%). The prevalence of type 2 diabetes was 10.6% in the younger adolescent group and 13.6% among older adolescents.
At 5-year follow-up, there was a similar BMI reduction maintained from baseline in the younger adolescent group (–22.2%; 95% confidence interval, –26.2% to –18.2%) and the older adolescent group (–24.6%; 95% CI, –27.7% to –22.5%; P = .59). There was a similar number of participants who had remission of dyslipidemia at 5 years in the younger adolescent group (61%; 95% CI, 46.3%-81.1%) and older adolescent group (58%; 95% CI, 48.0%-68.9%; P = .74). In participants with hypertension, 77% of younger adolescents (95% CI, 57.1%-100.0%) and 67% of older adolescents (95% CI, 54.5%-81.5%) achieved remission at 5 years after MBS, which showed no significant differences after adjustment (P = .84). For participants with type 2 diabetes at baseline, 83% of younger adolescents (6 participants) and 87% of older adolescents (15 participants) experienced remission by 5 years after surgery. Participants in both younger and older adolescent groups had similar quality of life scores at 5 years after surgery. When analyzing nutritional abnormalities, the researchers found younger adolescents in the group were less at risk for elevated transferrin levels (prevalence ratio, 0.52; P = .048) as well as less likely to have low vitamin D levels (prevalence ratio, 0.8; P = .034).
Pediatricians still concerned about safety
In an interview, Kelly A. Curran, MD, MA, assistant professor of pediatrics at University of Oklahoma Children’s Hospital in Oklahoma City, said that the findings by Dr. Ogle and colleagues add to a “growing body of literature about the importance of bariatric surgery for both younger and older adolescents.
“While many often see bariatric surgery as a ‘last resort,’ this study shows good outcomes in resolving obesity-related health conditions in both young and older teens over time – and something that should be considered more frequently than it is currently being used,” she said.
Guidelines from the American Society for Metabolic and Bariatric Surgery removed a restriction for younger age before a patient undergoes MBS, and a policy statement from the American Academy of Pediatrics encouraged increased use and access to MBS for younger adolescents. However, Dr. Curran noted that many pediatricians are still concerned about performing MBS on younger adolescents.
“Despite growing evidence of safety, I think many pediatricians worry about the potential for unintended consequences and potential impact on adolescent development or for lifelong micronutrition deficiencies – especially as there are no longitudinal studies over a lifetime,” she said.
“[W]ith the growing obesity epidemic and the long-term consequences of obesity on health and quality of life – the potential to help impact adolescents’ lives – for now and for the future – is impressive,” Dr. Curran said, acknowledging the ethical challenges involved with performing MBS on a patient who may be too young to understand the full risks and benefits of surgery.
“There are always inherent ethical challenges in providing surgery for patients too young to understand – we are asking parents to act in their child’s best interests, which may be murky to elucidate,” she explained. “While there is [a] growing body of literature around the safety and efficacy in bariatric surgery for children and adolescents, there are still many unanswered questions that remain – especially for parents. Parents can feel trapped in between these two choices – have children undergo surgery or stick with potentially less effective medical management.”
The limitations of the study include its observational nature, small sample size of some comorbidities, and a lack of diversity among participants, most of whom were White and female. In addition, “long-term studies examining the impact of bariatric surgery during adolescence would be important to give more perspective and guidance on the risks and benefits for teens,” Dr. Curran said.
The study was funded by the National Institutes of Health and grants from the National Institute of Diabetes and Digestive and Kidney Diseases as well as grants from Cincinnati Children’s Hospital Medical Center, Nationwide Children’s Hospital, Texas Children’s Hospital and Baylor College of Medicine, University of Pittsburgh, and the University of Alabama at Birmingham. The authors and Dr. Curran reported no conflicts of interest.
