Emotional eating as predictor of weight loss 2 years after Roux-en-Y gastric bypass

Assessing how bariatric surgery, emotional eating, and depression could affect each other: A cross-sectional study

Emotional eating (EE) has been found to be associated with depression, anxiety, excessive weight, obesity, and unhealthy eating habits. EE could also be associated with recurrent weight gain. To date, the factors predicting success following bariatric surgery remain uncertain. In addition, there is a paucity of data regarding the associations between EE, percent of total weight loss (TWL), and depression after bariatric surgery. The aims of this study were to evaluate the relationship between EE behavior, depression, and TWL, and to identify other factors, such as the type of bariatric surgery, that may have an impact on EE, depression and TWL after bariatric surgery. A self-report questionnaire was administered to 253 patients who underwent bariatric surgery between 2014 and 2021 at the Department of General Surgery, Faculty of Medicine, Gazi University. In total, 115 patients agreed to participate and completed the questionnaire. The administered scales consisted of the Sociodemographic Data Form, Emotional Eating Scale (EES), and Beck Depression Inventory (BDI). The participants were divided into the Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) groups. The RYGB and SG groups included 79 (68.8%) and 36 (31.3%) patients, respectively. A significant difference was found in terms of age (P = .002) and gender (P = .033). The BDI scores (P = .499) and TWL (P = .068) did not differ significantly. The EES score was higher in the SG group (P = .020). Between the groups with and without EE, age (P = .004) and BDI scores (P = .004) were significantly different. In correlation analyses, EES score was related to BDI score(ρ = 0.402, P < .001) and age(ρ = -0.348, P = .002) in the RYGB group. In regression analyses, TWL was associated with age (β = -0.366, P < .001) and surgery type (β = -6.740, P < .001), EES score was associated with BDI score (β = 0.149, P = .009) and age (β = -0.154, P = .006), and BDI score was associated with EES score (β = 0.419, P = .009) and age (β = -195, P = .041). In patients with moderate-to-severe depression, TWL was higher than in those without depression (P = .025). The effect of emotional eating and depression on TWL was not detected. Emotional eating and depression trigger each other in the individuals who underwent bariatric surgery. Young individuals who undergo bariatric surgery are more vulnerable to emotional eating and depression than older patients.

Characterizing emotional eating: Ecological momentary assessment with person-specific modeling

Emotional eating is a topic of clinical importance, with links to weight regulation and wellness. However, issues of concept clarity and measurement can interfere with efforts to understand and intervene on emotional eating. One explanation for prior difficulties in defining emotional eating may be that this construct is not uniform across individuals. The current study critically examined emotional eating by combining ecological momentary assessment (EMA) with an idiographic analytic approach. The study examined the heterogeneity in the emotions and dysregulated eating behaviors often thought to underlie emotional eating, by establishing and comparing latent factor profiles across individuals. Ten community adults with overweight or obesity completed a 21-day EMA protocol, with 5 daily prompts to report on relevant emotions and eating behaviors. P-technique factor analysis was used to examine the data. Results suggested variability across individuals in the number of factors that emerged, the items that loaded on each factor, and the strength of loadings. Dysregulated eating was not found to covary with affective states strongly enough to produce a distinct "emotional eating" factor for any individual, nor did the correlations between factors suggest strong relationships between emotions and dysregulated eating for most participants, even in this sample with 90% of participants self-identifying as "emotional eaters." Findings are consistent with a growing body of literature questioning the validity of the "emotional eating" construct as currently defined and measured, and supports conceptualizing emotional eating as a locally heterogenous construct that varies between people. Combining EMA with an intra-individual modeling technique appears to be a promising approach for understanding emotional eating. Additional work with larger samples is needed to capture the full range in individual profiles.

Emotional eating as predictor of weight loss 2 years after Roux-en-Y gastric bypass

There has been little agreement on the predictive value of emotional eating on weight loss outcomes after bariatric surgery. The aim of this study was to examine the predictive value of preoperative emotional eating, in response to clearly labelled emotions and diffuse emotions, on excess weight loss (EWL) and total weight loss (TWL) 2 years after Roux-en-Y gastric bypass (RYGB). All participants included in this retrospective cohort study were screened for RYGB surgery by a multidisciplinary team. The level of emotional eating was derived from the Dutch Eating Behaviour Questionnaire (DEBQ); the level of psychological variables from the Symptom Checklist-90. Participants were clustered, based on their DEBQ score, in high and low emotional eaters. Multiple linear regression analyses were performed to examine the association between preoperative emotional eating and EWL, and TWL. There were no significant differences in EWL of the 172 included participants, defined as either high or low emotional eaters (EWL 82.7% ±18.2 versus 82.4% ±21.3, respectively). Based on the regression analysis, emotional eating was not significantly associated with EWL, nor with TWL. When corrected for psychological, demographic and biological variables, preoperative emotional eating in response to diffuse emotions negatively affected EWL (β = -0.16, P = 0.048), although this was not applicable for TWL. Preoperative emotional eating does not seem to influence EWL, nor TWL 2 years after RYGB. Since this study faced multiple limitations, further investigation is required regarding the predictive value of emotional eating.
