The impact of psychological support on weight loss post weight loss surgery: a randomised control trial
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
Racial Differences in Psychological Symptoms and Eating Behaviors Among Bariatric Surgery Candidates
BACKGROUND: Black patients typically lose less weight than White patients following bariatric surgery; however, the reasons for this racial disparity are unclear. The purpose of the current study was to evaluate whether there are differences in psychiatric symptoms and problematic eating behaviors between White and Black patients pursuing bariatric surgery as this may aid in understanding postsurgical weight loss disparities and inform psychosocial assessment of bariatric candidates.
METHODS: A retrospective chart review was conducted of participants (N = 284) who completed a psychological evaluation prior to surgery. Information collected included history of binge eating and purging as well as data from measures administered (i.e., the Hospital Anxiety and Depression Scale, the Emotional Eating Scale, and the Yale Food Addiction Scale 2.0).
RESULTS: White patients reported higher levels of eating in response to anger/frustration (p = .03) and eating in response to depression (p = .01) than Black patients. White patients also reported more symptoms of food addiction, a difference that was trending toward significance (p = .05). No significant differences were found on measures of anxiety or depression.
CONCLUSION: White patients appear to have higher levels of presurgical problematic eating as compared with Black patients pursuing bariatric surgery; thus, these measurements of problematic eating may not explain the racial disparity in outcomes. However, future research should determine whether measures are valid among diverse populations and identify additional factors that may contribute to racial disparities in bariatric outcomes
