Abstract

Background

Bariatric surgery is an effective intervention for the majority of patients with morbid obesity, but a significant minority fails to achieve substantial weight loss. In the search of possible predictors of weight loss following bariatric surgery, preoperative factors turn out to have limited predictive power. This study will examine the impact of two postoperative factors on weight loss: perceived social support and stressful life events.

Methods

From the entire 2013 cohort that underwent laparoscopic Roux-and-Y gastric bypass (LRYGB) in a general hospital in the Netherlands, a group of 56 non-responders and a matched group of 56 responders were selected, using an alterable weight loss (%AWL)-based percentile chart. Patients from both groups were interviewed by phone to collect data on demographics, medical complications and comorbidities, social support and stressful life events. A total of 61 patients completed the data collection (54% response rate).

Results

One-way ANOVA analysis showed that responders and non-responders differed with regard to perceived support (F(1) = 8.60, p = .005). In a model with place of birth, level of education and pre-surgery diabetes mellitus as covariates, perceived social support was able to classify 83.6% of patients correctly as either responder or non-responder (χ 2 = 28.26, p < .001). Stressful life events turned out to be unrelated to weight loss.

Conclusions

Perceived social support differentiates responders from non-responders after LRYGB. When patients present themselves after LRYGB with sub-optimal weight loss, social support should be a focus of attention.
