Abstract

Purpose: Prevalence of obesity in Asia has been on the increasing trend, with corresponding increase in utilisation of bariatric surgery. The objective of this study was to examine differences in weight loss outcomes following bariatric surgery between Asian ethnicities. Materials and Methods: A retrospective database review was conducted of patients undergoing primary laparoscopic sleeve gastrectomy between 2009 and 2013 in 14 centres from Singapore, Malaysia, Taiwan, Hong Kong, Japan, Korea, India, Australia, Switzerland, and the USA. All patients with available follow-up data at 12 months and 36 months post-surgery were included in this study. Outcome measures used were percentage excess weight loss (%EWL) and percentage total weight loss (%TWL). Differences in outcomes between ethnicities were analysed after adjusting for age, gender, baseline body mass index (BMI), and presence of diabetes. Results: The study population (n = 2150) consisted of 1122 Chinese, 187 Malays, 309 Indians, 67 Japanese, 259 Koreans, and 206 Caucasians. 67.1% were female and 32.9% were male. Mean age was 37.1 ± 11.2 years. Mean pre-operative BMI was 40.7 ± 8.1 kg/m². With the Caucasian population as reference, Japanese had the best %TWL (3.90, 95% CI 1.16–6.63, p < 0.05) and %EWL (18.55, 95% CI 10.33–26.77, p < 0.05) while the Malays had the worst outcomes. Both Chinese and Koreans had better %EWL but worse %TWL as compared to Caucasians and there were no significant differences with the Indian study group. Conclusion: There are differences in weight loss outcomes following bariatric surgery between Asian ethnicities.
