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

摘要

AIM:To investigate whether or not bariatric surgeryweight 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 2010from 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,being34.3 kg(95%CI:30.0-38.5 kg)for Hispanics,33.8 kg(95%CI:27.3-40.3 kg)for non-Hispanic blacks,and32.8 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.
