Eating expectancies before bariatric surgery: assessment and associations with weight loss trajectories.

ABSTRACT:

Background

While presurgical eating behaviors have demonstrated limited prognostic value, cognitions regarding the effects of eating may serve as important predictors of weight loss outcomes after bariatric surgery. The Eating Expectancies Inventory (EEI) is a commonly used, self-report measure of expected consequences of eating; however, its psychometric and predictive properties have not yet been evaluated among bariatric surgery patients.

Objectives

This study sought to examine the factor structure and internal consistency of the EEI among bariatric surgery candidates, to examine relationships between EEI factors and measures of eating psychopathology, and to explore the effects of eating expectancies on postsurgical weight loss.

Setting

Data originated from an interdisciplinary bariatric surgery center in the Midwest United States.

Methods

Two hundred sixty-two women completed self-report questionnaires before bariatric surgery. Presurgical data and available postsurgical weights (at 6, 12, and 18 mo) were obtained from medical records.

Results

Analyses indicated that the original 5-factor model was a good-to-excellent fit for the EEI data. All EEI factors demonstrated good reliability and were significantly associated with eating disorder symptoms and behaviors at baseline. Higher scores on EEI Factor 1 (negative affect) and Factor 5 (alleviates boredom) predicted poorer weight loss at 18 months postsurgery (n = 132).

Conclusions

Findings support the reliability and validity of the EEI among female bariatric candidates. Presurgical eating expectancies were linked to pathologic eating patterns and also predicted postsurgical weight loss trajectories, suggesting that eating expectancies may have prognostic value as predictors of bariatric surgery outcomes.

Project description:BackgroundDepression and binge eating disorder (BED) are prevalent among bariatric surgery candidates. Depression subtypes may be differentially related to obesity, such that the atypical subtype predicts poorer outcomes. However, no research has examined depression subtypes, BED, and weight loss in bariatric candidates.ObjectiveTo examine whether presurgical atypical depressive symptoms, compared with no depressive and melancholic depressive symptoms, were associated with higher rates of presurgical BED, binge eating severity, and poorer postsurgical weight loss trajectories among bariatric candidates.SettingAn outpatient Midwest bariatric clinic.MethodsParticipants were 345 adults (aged 46.27 ± 12.78 yr, 76% female; body mass index = 49.84 ± 8.51 kg/m2) who received a presurgical evaluation. Depression subtypes (melancholic, atypical, and no depressive symptoms) were categorized using the Beck Depression Inventory-II. BED diagnosis and severity were evaluated using the Eating Disorder Diagnostic Scale and Binge Eating Scale, respectively. Weight loss trajectories were calculated as percent total weight loss postsurgery.ResultsUsing no depression as the referent, participants reporting melancholic symptoms (odds ratio = 7.60, P < .001 confidence interval95 [2.59-22.28]) and atypical symptoms (odds ratio = 10.11, P < .01 confidence interval95 [2.69-37.94]) were more likely to meet criteria for BED. Patients with atypical depressive symptoms exhibited the highest binge eating severity scores (mean = 23.03). Depression subtypes did not predict percent total weight loss trajectories within 18-months postbariatric surgery.ConclusionsPatients reporting preoperative atypical depressive symptoms were more likely to meet criteria for co-morbid BED diagnosis and have greater binge eating severity but did not have poorer weight loss within 18 months postsurgery. Future studies with longer-term follow-up and corresponding measures of postsurgical depression and binge eating pathology are warranted.

Project description:ObjectiveGreater perceived social support (PSS) is associated with more favorable changes in weight loss, activity behaviors, and eating regulation after metabolic and bariatric surgery (MBS). However, studies have relied on generic, retrospective PSS measures, and stability of PSS levels and relations with weight loss and weight-related behaviors over time is unknown. Using smartphone-based Ecological Momentary Assessment, this study evaluated pre-to 1-year post-MBS changes in daily weight management-focused PSS and associations with weight loss, device-measured activity behaviors, and eating regulation before and during the initial year after MBS.MethodAdult MBS patients (n = 71) received (1) an accelerometer to measure daily moderate-to-vigorous intensity physical activity (MVPA) and sedentary time (ST) minutes/day, and (2) a smartphone to complete morning weight-focused PSS ratings and eating regulation (dietary restraint/disinhibition) ratings at four semi-random times daily for 10 days at pre- and 3, 6, and 12-month postoperative. Generalized linear mixed models analyzed the associations of PSS with total weight loss (%TWL) and activity/eating outcomes.ResultsParticipants on average reported relatively stable moderate-to-high PSS (3.98 on one to five scale) across assessments. Perceived social support was not related to %TWL, MVPA, or ST. Participants with higher PSS reported lower disinhibition and higher restraint than those with lower PSS (ps < 0.05); however, participants reported higher restraint on days that PSS was lower than their usual levels (p = 0.009).ConclusionsMBS patients on average had stable PSS levels across time. Higher PSS levels were associated with greater resistance to overeating cues (disinhibition) and cognitive control to restrict food intake (restraint) over time. Additionally, participants reported higher restraint when PSS levels were lower than usual. Overall, weight-focused PSS appeared to hold greater importance in relation to regulating eating behavior than engaging in activity behaviors or weight loss among MBS patients during the initial postoperative year.Clinical trial registrationNCT02777177.
