Abstract/Summary

Background The purpose of the present study is to evaluate the impact of a health psychology-led bariatric rehabilitation service (BRS) on patient weight loss following bariatric surgery at 1 year. Methods A single-site open-randomised parallel group control trial based at St. Richard’s Hospital in Chichester in the UK. Patients (n=162) were recruited immediately prior to Roux-en-Y gastric bypass and randomly allocated to receive either treatment as usual (n=80) or the BRS (n=82). The BRS involved three 50-min one-to-one sessions with a health psychologist and provided information, support and mentoring pre and post surgery addressing psychological issues such as dietary control, self esteem, coping and emotional eating. Weight loss was assessed at 1 year. The key outcome variable was BMI and change in BMI. Results Follow-up weight was available for 145 patients. Intention-to-treat analysis (n=162) using last measured weights showed that mean change in BMI by 1 year post surgery was −16.49. There was no significant difference between the two groups (control group=−16.37, 95 % CI= 15.15–17.57; intervention=−16.6, 95 % CI=15.42–17.81; ηp 2=0.001). Similarly, explanatory analysis (n=145) showed a mean change inBMI of −17.17. The difference between the two groups was not significant (control group=−16.9, 95 % CI=15.78–18.18; intervention=−17.35, 95 % CI=18.5– 16.16; ηp 2=0.001). Conclusions Psychological support pre and post bariatric surgery had no impact on weight loss as measured by BMI and change in BMI by 1 year. It is argued that psychological support should be targeted to patients who start to demonstrate weight regain at a later stage.
