Abstract

Purpose

Engaging in a healthy lifestyle after bariatric surgery is essential to optimize and sustain weight loss in the long term. There is promising evidence that social support of patients who undergo bariatric surgery plays an important role in promoting a better quality of life and adherence to the required behavioral changes and medical appointments. This study sought to investigate: (a) if post-operative patients experience different levels of perceived social support compared to pre-operative patients; (b) correlations between perceived social support, depression, disordered eating, and weight outcomes; (c) if social support is a moderator between psychological distress, and disordered eating behavior and weight outcomes.

Methods

A group of 65 patients assessed pre-surgery and another group of 65 patients assessed post-surgery (M = 26.12; SD 7.97 months since surgery) responded to a set of self-report measures assessing social support, eating disorder psychopathology, disordered eating, and depression.

Results

Greater social support was associated with lower depression, emotional eating, weight and shape concerns, and greater weight loss in pre- and post-surgery groups. Social support was found to be a moderator between different psychological/weight variables but only for the post-surgery group: the relation between depression and eating disorder psychopathology or weight loss was significant for patients scoring medium to high level is social support; the relation between grazing and weight regain was significant for patients scoring medium to low levels of social support.

Conclusions

The associations found between perceived social support and depression, disordered eating and weight outcomes highlight the importance of considering and working with the social support network of patients undergoing bariatric surgery to optimize treatment outcomes.

Level of Evidence  Level III: case-control study.
