Abstract

Background

Social deprivation is associated with a greater morbidity and shorter life expectancy. This study evaluates differences in weight loss following bariatric surgery and deprivation, based on UK deprivation measures in a London bariatric centre.

Methods

All patients undergoing bariatric surgery between 2002 and 2012 were retrospectively identified. Demographic details, type of surgery and percentage excess weight loss data were collected. UK Index of Multiple Deprivation (IMD, 2010) and IMD domain of the Health Deprivation and Disability (HDD) scores were used to assess deprivation (where 1 is the most deprived in rank order and 32,482 is the least deprived). Two-way between-subjects analysis of variance (ANOVA) was performed to examine the effect of IMD score, deprivation, procedure type and gender on percentage excess weight loss.

Results

Data were included from 983 patients (178 male, 805 female) involving 3,663 patient episodes. Treatments comprised laparoscopic gastric bands (n = 533), gastric bypass (n = 362) and gastric balloons (n = 88). The average percentage excess weight loss across all procedures was 38 % over a follow-up period (3 months–9 years). There was no correlation between weight loss and IMD/HDD rank scores. Gastric bypass was significantly more effective at achieving weight loss than the other two procedures at 3-, 6- and 9-month and 1-year follow-up.

Conclusions

Social deprivation does not influence weight loss after bariatric surgery, suggesting that all socioeconomic groups may equally benefit from surgical intervention. Social deprivation should not therefore negatively influence the decision for surgical intervention in these patients.
