RESUMO

Background/Objectives: Metabolic and bariatric surgery (MBS) is the most effective treatment for severe obesity; however, a significant subset of patients does not achieve expected weight loss or have substantial weight recurrence over time. The intestinal energy harvest is a potential determinant of varying weight loss outcomes, but with limited exploration. We assess the relationships between diet, intestinal energy harvest, and weight outcomes over 24 months in individuals who have undergone MBS. Subjects/Methods: Calorie absorption was assessed with bomb calorimetry and dietary questionnaires before and after MBS. Within a total of 67 patients, fecal energy density was measured in 67, 56, 60, 67, 44, 47 samples at 0, 1, 6, 12, 18, and 24 months, respectively. Multivariate regression was developed to identify potential weight loss predictors, and random forest algorithms were employed to forecast weight results based on intestinal energy harvest. Results: Intestinal energy harvest enhanced the predictability of patient weight loss outcomes with random forest models. A notable difference in relative fecal energy content was observed between patients experiencing optimal and sub-optimal weight loss (p<0.01). Prior to MBS, an increased energy content in feces (indicating less energy absorption) is associated with greater weight loss after the operation. Associations between diet and energy harvest were insignificant. Conclusion: MBS changes energy harvest capacity post-surgery. A higher relative fecal energy content (lower energy absorption) at one month correlates with better weight loss outcomes at 6M, 12M, 18M and 24M post-MBS. Findings may guide the development of diagnostic tools and treatment guidelines for patients at risk of suboptimal weight loss outcomes. CLINICAL TRIAL REGISTRATION: The trial is registered at clinicaltrials.gov (NCT03065426).

RESUMO

BACKGROUND: Metabolic and bariatric surgery (MBS) leads to beneficial and sustained outcomes. However, many patients evidence weight recurrence and psychosocial functioning may be associated with weight recurrence. The Minnesota Multiphasic Personality Inventory - 3 (MMPI-3) is validated for use in presurgical MBS evaluations and likely has clinical utility in understanding weight recurrence and other aspects of postoperative functioning. OBJECTIVE: The objective of the current investigation is to understand how postoperative psychosocial functioning relates to weight recurrence and other behaviors and constructs 6 years after MBS. SETTING: Cleveland Clinic Bariatric and Metabolic Institute. METHODS: A sample of 163 participants consented to take a battery of self-report measures related to psychological functioning, eating behaviors, adherence, alcohol misuse, and quality of life along with their postoperative weight. MMPI-3 scale scores were prorated from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form (MMPI-2-RF) or scored from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form - Expanded (MMPI-2-RF-EX). RESULTS: Weight recurrence was quite variable in this sample. Postoperative MMPI-3 scales related to emotional/internalizing dysfunction were modestly associated with higher weight recurrence. Postoperative MMPI-3 scale scores also demonstrated associations with other postoperative outcomes including measures of eating behaviors, adherence, alcohol misuse, and quality of life. CONCLUSIONS: Postoperative psychosocial functioning as assessed by the MMPI-3 was associated with weight recurrence and a number of other problematic psychological outcomes beyond weight recurrence.

RESUMO

Metabolic and bariatric surgery (MBS) is the most effective long-term treatment for Class III obesity. Reduced dietary intake is considered a behavioral driver of post-surgical weight loss, but limited data have examined this association. Therefore, this study examined prospective, longitudinal relationships between dietary intake and weight loss over 24 months following Roux-en-Y Gastric Bypass and Sleeve Gastrectomy. Relationships between weight loss and dietary intake were examined using a validated 24-h dietary recall method. Associations between total energy/macronutrient intake and weight loss outcomes were assessed at 12-, 18-, and 24-months following MBS, defining patients as "responders" and "suboptimal responders". Consistent with previous literature, 12-month responders and suboptimal responders showed significant associations between weight loss and energy (p = 0.018), protein (p = 0.002), and total fat intake (p = 0.005). However, this study also revealed that many of these associations are no longer significant 24 months post-MBS (p > 0.05), despite consistent weight loss trends. This study suggests a short-term signal between these dietary factors and weight loss outcomes 12 months post-MBS; however, this signal does not persist beyond 12 months. These results are essential for interpreting and designing clinical studies measuring long-term post-surgical weight loss outcomes.

RESUMO

BACKGROUND: Obesity is associated with cognitive impairment. A potential contributor to these deficits is sedentary behavior (SB), which is linked to poorer cognitive functioning in other populations. Little is known about the association between SB and cognitive function in bariatric surgery populations. OBJECTIVES: This cross-sectional study examined the association between SB and cognitive function in preoperative bariatric surgery patients, as well as possible sex differences in this relationship. SETTING: Data were collected at 2 health centers in the United States. METHODS: A total of 121 participants (43.2 ± 10.3 yr of age) scheduled for Roux-en-Y gastric bypass or sleeve gastrectomy completed the National Institute of Health (NIH) Toolbox for the Assessment of Neurological and Behavioral Function Cognition Domain, a computerized neuropsychological assessment battery. Participants wore a waist-mounted accelerometer for 7 consecutive days to measure SB and light-intensity physical activity (LPA). RESULTS: Pearson and partial correlations found no significant relationships between cognitive function and SB or LPA in the full sample. However, partial correlations controlling for LPA found that greater SB was associated with poorer performance on List Sorting Working Memory Test in women (r = -.28; P = .006), whereas there was a positive relationship between SB and Dimensional Change Card Sort for men (r = .51; P = .015; 95% CI [.25, .73]). CONCLUSIONS: These results showed that greater SB, independent of LPA, is associated with poorer working memory in women and better set shifting ability in men. Future studies should examine the possibility of domain-specific cognitive effects associated with SB in bariatric surgery samples and clarify possible sex differences.

RESUMO

INTRODUCTION: Patients who undergo metabolic and bariatric surgery (MBS) are advised to make healthy activity and dietary changes. While previous research has examined post-surgical changes in activity and dietary behaviors separately, no study has assessed whether changes in these behaviors are beneficially associated with each other. We evaluated whether post-surgical improvements in activity behaviors related to favorable changes in dietary behaviors overall and by surgery type (Roux-en-Y gastric bypass [RYGB], sleeve gastrectomy [SG]). METHODS: At pre-surgery and 6- and 12-months post-surgery, participants (N = 97; 67 RYGB/30 SG) wore an accelerometer for 7 days and completed 24-h dietary assessments on 3 days. General linear models assessed associations between pre- to post-surgical changes in activity (moderate-to-vigorous physical intensity activity [MVPA], sedentary time [ST]) and dietary (total energy intake [EI; kcal/day], dietary quality [healthy eating index/HEI scores]) behaviors, with surgery type as a moderator. RESULTS: Participants on average: demonstrated small, non-significant post-surgical changes in MVPA and ST minutes/day (ps > .05); and reported significant post-surgical decreases in EI (p < .001), but no changes in HEI scores (ps > .25). Greater 12-month post-surgical increases in MVPA were significantly associated with greater decreases in EI, but only for RYGB participants (p < .001). DISCUSSION: Participants reported large decreases in EI, but made minimal changes in other behaviors after MBS. Results suggest greater increases in MVPA could assist with achieving greater decreases in EI, although this benefit appears to be limited to RYGB patients. Additional research is needed to confirm these findings and determine whether activity-dietary behavior associations differ beyond the immediate post-surgical year.

RESUMO

BACKGROUND: Metabolic and bariatric surgery is effective for sustained weight loss, but binge eating disorder (BED) can be associated with poorer outcomes and lead to weight regain. A common measure used to screen for BED is the Binge Eating Scale (BES). A BES cut-off score of ≥17 previously identified patients who have a high likelihood of meeting criteria for BED. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), lowered the threshold for meeting criteria for BED, and the psychometrics of the BES need to be reevaluated. OBJECTIVE: The objective of the current investigation is to evaluate whether alternative cut-scores on the BES result in better classification of BED based on the DSM-5 revision of the the BED diagnostic criteria. SETTING: Academic medical hospital in the Midwestern United States. METHODS: Patients (n =1133) seeking metabolic and bariatric surgery were randomly split into 2 samples for validation and replication. The validation sample consisted of 561 patients (30.1% men, 35% non-White). The replication sample consisted of 572 patients who were demographically similar to the first random split sample (e.g., 25.3% men, 34.4% non-White). RESULTS: Of these patients, 13.5% met DSM-5 criteria for BED in the validation sample and 13.8% met criteria for BED in the replication sample. Lowering the interpretative cut-off to ≥15 on the BES yielded sensitivity values of >.72, specificity values of >.67, and an accurate classification of BED in >.70 of patients across both samples. These classification values were as good as or better than the standard cut-off score of ≥17 in both samples. CONCLUSIONS: The BES is appropriate to screen for BED in patients who are seeking bariatric surgery. A 2-point decrease in the BES score for clinical interpretation is appropriate-lowering it from 17 to 15 given DSM-5 updates to diagnostic criteria.

RESUMO

¼: Mental health evaluation should be considered an essential part of the routine preoperative assessment and should be managed by a multidisciplinary team composed of the primary care physician, orthopaedic provider, and behavioral health specialist. ¼: The scientific literature indicates that patients without comorbid psychiatric symptoms and adaptive coping strategies, resilience, and well-managed expectations have improved functional outcomes and satisfaction after orthopaedic procedures. ¼: Psychological issues are multifaceted and require treatment tailored to each individual patient. Therefore, close communication between all members of the care team is required to create and execute the perioperative plan.

RESUMO

PURPOSE OF REVIEW: Social isolation and loneliness have long been identified as risk factors for poorer physical and mental health and increased mortality. These factors have also been shown to impact dietary behavior and physical activity which play a role in precipitating and maintaining obesity. Less is known about the impact of social isolation resulting from the COVID-19 pandemic in which social distancing is a major component of public health initiatives. This narrative review will examine the existing literature on the relationships between social isolation, loneliness, mental health, and weight as they relate to the COVID-19 pandemic. RECENT FINDINGS: Individuals with obesity are at very high risk for worsening course of COVID-19, hospitalization, and death. This population may also be more significantly impacted by the dietary and physical activity consequences resulting from lockdown, social distancing, and isolation. The pandemic has led to significant lifestyle disruptions. However, early studies have largely relied upon cross-sectional studies or convenience samples. Future research will need to study the impact more rigorously, particularly among populations at greatest risk.

RESUMO

Eating disorders are associated with significant medical morbidity and mortality and serious psychological impairment. Individuals seeking bariatric surgery represent a high-risk group for evidencing disordered eating and eating disorders, with some patients experiencing the persistence or onset of disordered eating postsurgery. This review synthesizes the available literature on problematic or disordered eating in the bariatric field, followed by a review of measurement and conceptual considerations related to the use of eating disorder assessment tools within the bariatric population.

RESUMO

Bariatric surgery induces significant shifts in the gut microbiota which could potentially contribute to weight loss and metabolic benefits. The aim of this study was to characterize a microbial signature following Roux-en-Y Gastric bypass (RYGB) surgery using novel and existing gut microbiota sequence data. We generated 16S rRNA gene and metagenomic sequences from fecal samples from patients undergoing RYGB surgery (n = 61 for 16S rRNA gene and n = 135 for metagenomics) at pre-surgical baseline and one, six, and twelve-month post-surgery. We compared these data with three smaller publicly available 16S rRNA gene and one metagenomic datasets from patients who also underwent RYGB surgery. Linear mixed models and machine learning approaches were used to examine the presence of a common microbial signature across studies. Comparison of our new sequences with previous longitudinal studies revealed strikingly similar profiles in both fecal microbiota composition (r = 0.41 ± 0.10; p < .05) and metabolic pathways (r = 0.70 ± 0.05; p < .001) early after surgery across multiple datasets. Notably, Veillonella, Streptococcus, Gemella, Fusobacterium, Escherichia/Shigella, and Akkermansia increased after surgery, while Blautia decreased. Machine learning approaches revealed that the replicable gut microbiota signature associated with RYGB surgery could be used to discriminate pre- and post-surgical samples. Opportunistic pathogen abundance also increased post-surgery in a consistent manner across cohorts. Our study reveals a robust microbial signature involving many commensal and pathogenic taxa and metabolic pathways early after RYGB surgery across different studies and sites. Characterization of the effects of this robust microbial signature on outcomes of bariatric surgery could provide insights into the development of microbiome-based interventions for predicting or improving outcomes following surgery.

RESUMO

BACKGROUND: A psychosocial evaluation is an important component of the preoperative assessment process for people seeking metabolic and bariatric surgery (MBS), and is required for accreditation of MBS programs. Recently, independent companies without affiliations with MBS programs have been marketing remotely administered, unaffiliated psychosocial evaluations for MBS (RUS), and American Society for Metabolic and Bariatric Surgery (ASMBS) members have raised concerns about these evaluations. OBJECTIVES: To explore ASMBS members' beliefs about RUS. SETTING: Online survey. METHODS: We developed a survey to evaluate ASMBS members' opinions, experiences, and/or concerns about in-person and RUS psychosocial evaluations for MBS. RESULTS: In total, 635 ASMBS members responded to the online survey and 156 responded to an open-ended question on RUS. Responses were coded based on a manual developed for this study, yielding themes of concerns about the quality of RUS, lack of ongoing relationships in RUS, and conditions under which/reasons why RUS evaluations could be acceptable. CONCLUSION: Respondents expressed both interest in and concerns about RUS in pre-MBS psychosocial evaluations. Use of RUS has the potential to improve access to MBS by providing a convenient and efficient means of completing the psychosocial evaluation. Conversely, respondents expressed concerns about the background and training of RUS providers, the quality of the reports, and the limited relationships between the RUS provider and both the MBS patient and the MBS team. We discuss the clinical and research implications of response themes, particularly for patients in rural areas or those who have other barriers to care.

RESUMO

OBJECTIVE: Individuals with obesity frequently contend with chronic pain, but few studies address the clinical impact of coordinated pain services on this population. The current study addresses this topic by comparing the effectiveness of a comprehensive pain rehabilitation program for patients with and without obesity. METHODS: A retrospective analysis of registry data was conducted. Obesity was considered as one of three weight groups, based on the following body mass index cutoffs: normal weight (18.5 to < 25 kg/m2), overweight (25 to < 30 kg/m2), and obese (> 30 kg/m2). These groups were compared on the Pain Severity Ratings (PSR) Scale, the Pain Disability Index (PDI), and the Depression, Anxiety, Stress Scales-Short Form (DASS-SF). RESULTS: Groups differed on baseline pain disability and depression. Patients with obesity had higher scores on both the PDI (P = .028) and the DASS-SF depression subscale (P = .006). Contrary to the hypothesis, after controlling for baseline score and sex there were no significant differences between weight groups with regards to PSR, PDI, or any DASS-SF subscale at discharge. At 1-year follow-up, individuals who were overweight and obese had significantly more anxiety compared to individuals whose weight was in the normal range. CONCLUSIONS: Multidisciplinary pain rehabilitation programs appear to be an effective treatment intervention for patients who have concomitant chronic pain and obesity, to a degree comparable to patients who have chronic pain but do not contend with obesity. Implications for program development, clinical interventions, and future research are discussed.

RESUMO

Patients presenting for bariatric surgery have been shown to have high rates of psychiatric disorders. These studies have utilized structured interviews using older versions of the DSM. This study examined whether similar lifetime frequencies would be similar using the recent DSM-5. Participants (N = 131) were evaluated as part of a longitudinal study examining post-operative weight loss at two sites. Participants were administered the Structured Clinical Interview for DSM-5 (SCID5) pre-surgically. Lifetime estimates using the SCID5 were compared to the range and mean of 3 prior US studies and 2 international studies using the DSM-IV. Overall, frequency of psychiatric disorders was similar or lower than prior studies. Changes to diagnostic criteria may explain differences although future studies are needed to better characterize this population.

RESUMO

PURPOSE: A considerable number of post-bariatric surgery patients report problematic eating behaviors (PEBs) and/or eating disorders (EDs). Examining psychosocial variables associated with ED symptoms may identify targets for postoperative interventions to reduce these behaviors and improve surgical outcomes. METHODS: A total of 161 participants completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and the Eating Disorder Examination-Questionnaire (EDE-Q). Participants were classified into ED risk or no ED risk groups and subjective binge eating (SBE) or no SBE groups. Independent-sample t tests were computed to examine mean differences in total weight loss (%TWL) and MMPI-2-RF scale scores between the ED groups. Relative Risk Ratios (RRRs) were computed to determine which MMPI-2-RF scales were associated with increased risk of ED group membership. RESULTS: The ED risk group lost significantly less weight (19.36% TWL) than the no ED risk group (25.18% TWL). The SBE group lost significantly less weight (17.98% TWL) than the no SBE group (25.57% TWL). Participants in the ED groups scored significantly higher on internalizing and externalizing MMPI-2-RF scales than the no ED groups. These scales were associated with increased risk (1.55-2.55 times the risk) of being classified into the ED groups. CONCLUSIONS: Patients who experienced postoperative ED symptoms lost significantly less weight than patients without ED symptoms. Postoperative ED symptoms are related to, and may be impacted by, higher levels of internalizing and externalizing dysfunction after surgery. Postoperative assessment of and interventions targeting psychosocial dysfunction could decrease ED symptoms. LEVEL OF EVIDENCE: III: Evidence obtained from well-designed cohort or case-control analytic studies.

RESUMO

BACKGROUND: Research identifying preoperative psychosocial predictors of bariatric surgery outcomes has yielded inconsistent results with minimal examination of longer-term outcomes. Utilizing a broadband measure of personality and psychopathology during the preoperative evaluation helps to identify preoperative risk factors for suboptimal bariatric surgery outcomes. OBJECTIVE: Examine predictors of outcome and the incremental contribution of presurgical psychological testing to various long-term bariatric surgery outcomes. SETTING: Academic medical center. METHOD: A total of 168 postoperative patients (average of 6 postoperative years) consented to participate in the outcome study. Participants were weighed by the trained research/clinical staff and completed a battery of self-report questionnaires, including measures assessing eating attitudes and behaviors and weight-related quality-of-life (QoL). Patients had completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) as part of the institution's routine preoperative psychosocial evaluation. Weight loss was calculated as percent total weight loss (%TWL) and percent weight regain (%WR) was calculated as a percentage of maximum weight loss. Other preoperative data were obtained from a review of each patient's electronic medical record (EMR). From the initial sample, 145 patients were retained for analyses in the present study. RESULTS: Preoperative problematic eating variables predicted long-term postoperative problematic eating behaviors and body image concerns. Scores on preoperative MMPI-2-RF scales measuring Demoralization, Dysfunctional Negative Emotions, Antisocial Behaviors, and Hypomanic Activation were consistent incremental predictors of 6-year outcomes, accounting for an additional 3%-24% of the variability in postoperative eating behaviors and QoL. CONCLUSIONS: The preoperative psychological evaluation can be used to identify predictors of long-term bariatric surgery outcomes. Identification of these risk factors provides important targets for pre- and postoperative clinical interventions to maximize surgical outcomes.

RESUMO

BACKGROUND: Identifying which patients receive referrals to and which ones attend weight management programs can provide insights into how physicians manage obesity. OBJECTIVE: To describe patient factors associated with referrals, which primarily reflect physician priorities, and attendance, which reflects patient priorities. We also examine the influence of the individual physician by comparing adjusted rates of referral and attendance across physicians. DESIGN: Retrospective cohort study. PARTICIPANTS: Adults with a body mass index (BMI) ≥ 30 kg/m2 who had a primary care visit between 2015 and 2018 at a large integrated health system MAIN MEASURES: Referrals and visits to programs were collected from the EHR in 2019 and analyzed in 2019-2020. Multilevel logistic regression models were used to identify the association between patient characteristics and (1) receiving a referral, and (2) attending a visit after a referral. We compared physicians' adjusted probabilities of referring patients and of their patients attending a visit. KEY RESULTS: Our study included 160,163 adults, with a median BMI of 35 kg/m2. Seventeen percent of patients received ≥ 1 referral and 29% of those attended a visit. The adjusted odds of referral increased 57% for patients with a BMI 35-39 (versus 30-34) and 32% for each comorbidity (p < 0.01). Attending a visit was less strongly associated with BMI (aOR 1.18 for 35-39 versus 30-34, 95% CI 1.09-1.27) and not at all with comorbidity. For the physician-level analysis, the adjusted probability of referral had a much wider range (0 to 83%; mean = 19%) than did the adjusted probability of attendance (range 27 to 34%). CONCLUSIONS: Few patients attended a weight management program. Physicians vary greatly in their probability of referring patients to programs but not in their patients' probability of attending.

RESUMO

OBJECTIVE: To deliver effective care, healthcare systems should understand patients' preferences for weight management across a spectrum of needs. Our objective was to describe patients' perceptions of what helps or hinders weight loss and maintenance. METHODS: Semistructured interviews were conducted with patients who accessed weight management services at a large integrated health system in 2018. The interview guide was developed and iteratively refined through a literature search and by consulting experts. Questions included the respondent's weight history, interactions with the health system, and current health status. The analysis used a grounded theory approach, and each transcript was double-coded in 2019. Codes were sorted into themes. All discrepancies were resolved through team discussion. RESULTS: Fifteen patients were interviewed. The majority of respondents (87%) reported multiple weight loss attempts. Three themes were identified. First, advice should be matched to a patient's knowledge and prior experience (eg, using bariatric deck cards). As patients progressed, clinician advice also needed to advance (eg, explaining how to expand food options instead of defining a healthy diet). Second, respondents had a variety of motivating factors, and understanding where motivation is generated from can inform how to design a weight management approach. Third, patients need continual and long-term advice. Some respondents feared becoming ineligible for services if their weight dropped too much. CONCLUSIONS: Health systems can support patients by developing processes for identifying the extent of a patient's knowledge and giving personalized advice based on the patient's preferences and experiences. Reassessing needs at defined intervals may help patients attain and sustain their goals.

RESUMO

PURPOSE OF REVIEW: Marijuana use presents a unique challenge to bariatric surgery programs. We review the recent evidence examining marijuana use on outcomes following bariatric surgery. RECENT FINDINGS: Recent studies have not demonstrated an increased risk of short-term surgical complications or differences in up to 2-year weight loss following surgery among marijuana users. However, studies have demonstrated increased risks in two areas: pain management and problematic eating behaviors. Additionally, preoperative marijuana use has been linked to increased postoperative marijuana use which may undermine weight loss and increase risk for weight regain. There are still many unanswered questions regarding marijuana use and bariatric surgery, and the limited literature base has produced mixed results when considering marijuana as a contraindication for bariatric surgery. Programs must take into consideration the laws of their state, individual patterns of use, and route of administration when considering whether marijuana is a contraindication for surgery.

RESUMO

Eating pathology is common pre-operatively and continues to be prevalent following bariatric surgery. A new version of the Minnesota Multiphasic Personality Inventory (MMPI), the MMPI-3, contains a new scale called Eating Concerns (EAT) that aims to assess problematic eating behaviors. The current investigation seeks to establish preliminary convergent validity of the MMPI-3 EAT scale in a postoperative bariatric surgery sample. Thirty-eight consecutive participants took the MMPI-3 and the Eating Disorder Examination-Questionnaire (EDE-Q). Higher MMPI-3 EAT scale scores were meaningfully associated with %Weight Regain (r = .37) and scale scores on the EDE-Q [Eating Concerns (r = .67), Weight Concerns (r = .39), Shape Concerns (r = .54), and the EDE total score (r = .59)]. Initial examination of the EAT Specific Problem Scale of the MMPI-3 yields good clinical utility in assessing eating pathology in a postoperative bariatric surgery sample.

RESUMO

INTRODUCTION: Mental health professionals routinely assess psychosocial risk factors prior to bariatric surgery to help identify factors that may impede surgical outcomes. Data regarding longer-term psychosocial functioning postoperatively are needed. PURPOSE: Assess the psychosocial functioning of patients who obtained bariatric surgery approximately 6 years ago. METHODS: A total of 161 patients consented to participate in the outcome study. Participants were compensated for their time and participation. Participants were weighed by the research/clinical staff and asked to complete a battery of self-report measures, including the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Other measures targeted adherence, eating behaviors/body image, alcohol use, and quality of life. RESULTS: Postoperative MMPI-2-RF scores indicate psychosocial functioning is largely similar to previously published pre-surgical functioning data. Six-year weight loss outcomes were lower than previous studies reported for a similar postoperative time period (mean %total weight loss = 22.98%; standard deviation = 11.71), though quality of life scores were relatively high. Postoperative MMPI-2-RF scale scores were associated with poorer psychosocial functioning, reduced adherence, greater eating behaviors/body image concerns, greater alcohol use severity, lower quality of life, and less overall weight loss. CONCLUSIONS: Psychological dysfunction 6 years after surgery is associated with various adverse outcomes. Ongoing, postoperative treatment may result in better long-term functioning for patients.
