Effect of ethnicity on weight loss among adolescents 1 year after bariatric surgery

Abstract

AIM:To investigate whether or not bariatric surgery weight outcomes vary by ethnicity in a large, nationally representative sample of adolescents. METHODS:The Bariatric Outcomes Longitudinal Database was used for analysis and contains data on surgeries performed on adolescents from 2004 to 2010 from 423 surgeons at 360 facilities across the United States Adolescents (n = 827) between 11 and 19 years old who underwent either gastric bypass or adjustable gastric banding surgery were included in the analysis. Outcome measures included changes in anthropometric measurements [weight (kg) and body mass index] from baseline to 3 (n = 739), 6 (n = 512), and 12 (n = 247) mo after surgery. RESULTS:A year after patients underwent either gastric bypass (51%) or adjustable gastric banding (49%) surgery, mean estimated weight loss for all ethnic groups differed by a maximum of only 1.5 kg, being 34.3 kg (95%CI: 30.0-38.5 kg) for Hispanics, 33.8 kg (95%CI: 27.3-40.3 kg) for non-Hispanic blacks, and 32.8 kg (95%CI: 30.9-34.7 kg) for non-Hispanic whites. No overall pairwise group comparisons were significant, indicating that no ethnic group had better weight loss outcomes than did another. CONCLUSION:Bariatric surgery substantially reduces the weight of severely obese adolescents at 1 year post-procedure with little variation by ethnicity and/or gender. These results suggest that bariatric surgery is a safe and reasonable treatment for all severely obese adolescents with the appropriate indications. treatments for severe obesity. Among adults, outcomes of bariatric surgery differ by ethnicity. We tested whether this relationship is also true among adolescents. Outcome measures included changes in anthropometric measurements (weight and body mass index) from baseline (n = 827) to 1 year after surgery. Our results support the conclusion that bariatric surgery can substantially reduce weight in severely obese adolescents for at least 1 year, irrespective of their race or ethnicity. Ethnicity is a reasonable and safe treatment for all severely obese adolescents with the appropriate indications.

Interaction of race with weight loss and resolution of obesity co-morbidities in patients undergoing laparoscopic roux-en-y gastric bypass (lrygb): an analysis of 83,059 bold database patients00000000000

“…These observations contrast with publications in which depression and other Axis I disorders were associated with high pre-operative BMI, and with less weight reduction following bariatric surgery. 21,22 From the results of the present study, one might speculate that the higher rates of comorbidity persistence in Caucasians may have exacerbated depression and other psychological impairments for those patients. Although the causes of these racial variations are not clear from the data, increased post-LRYGB Caucasian depression is a significant new observation.…”

“…This is an important finding, as prior studies have not identified such statistically and clinically significant variations by race in the resolution of hypertension after LRYGB. 13,17,18,22 Consistent with the known increased prevalence of hypertension in the general African-American population, Adams observed the highest rates of hypertension in Asians and African-Americans among morbidly obese patients pre-operative for LRYGB. 1 The results here indicate that the increased African-American propensity for hypertension extends to impaired high blood pressure resolution following LRYGB.…”

“…These variations in post-LRYGB outcomes according to race have not been reported previously in the literature. 10,15,22,23 There are several limitations to this study. Firstly, the limits of a retrospective analysis of a prospectively collected database apply.…”

Physical and Psychological Effects of Bariatric Surgery on Obese Adolescents: A Review

“…The study, however, enrolled 74.4 percent European Americans, and only 25.6 percent African Americans, and it also studied adult, rather than adolescent, subjects. Based on the evidence, it appears that SES may be a bigger predictor of outcomes than ethnicity; however, not enough data exist to make a definitive conclusion ( 55 , 56 ). What can be assessed is that those of lower SES or living in rural areas further from reputable medical centers, have more post-operative complications and lower success rates than those with better access to resources ( 11 ).…”
