Prospective Study of Attachment as a Predictor of Binge Eating, Emotional Eating and Weight Loss Two Years after Bariatric Surgery

Bariatric surgery remains the most effective treatment for severe obesity, though post-surgical outcomes are variable with respect to long-term weight loss and eating-related psychopathology. Attachment style is an important variable affecting eating psychopathology among individuals with obesity. To date, studies examining eating psychopathology and attachment style in bariatric surgery populations have been limited to pre-surgery samples and cross-sectional study design. The current prospective study sought to determine whether attachment insecurity is associated with binge eating, emotional eating, and weight loss outcomes at 2-years post-surgery. Patients (n = 108) completed questionnaires on attachment style (ECR-16), binge eating (BES), emotional eating (EES), depression (PHQ-9), and anxiety (GAD-7). Multivariate linear regression analyses were conducted to examine the association between attachment insecurity and 2-years post-surgery disordered eating and percent total weight loss. Female gender was found to be a significant predictor of binge eating (p = 0.007) and emotional eating (p = 0.023) at 2-years post-surgery. Avoidant attachment (p = 0.009) was also found to be a significant predictor of binge eating at 2-years post-surgery. To our knowledge, this study is the first to explore attachment style as a predictor of long-term post-operative eating pathology and weight outcomes in bariatric surgery patients.

Introduction. Obesity is a chronic disease with a great impact on the cardiovascular system through its association with type II diabetes, hypertension, dyslipidemia, metabolic syndrome (MetS) and also through direct alterations in cardiac performance and morphology. Recent long term studies prove that substantial weight loss obtained via bariatric surgery is capable of improving cardiac risk factors associated with severe obesity, decreasing the mortality rates.Aim: to assess the long-term changes in cardiovascular risk and cardiac structure in obese patients who had lost weight after laparoscopic sleeve gastrectomy (LSG).Methods. Fifty-two severe obese patients (44±9 years, 57.7% women, BMI=45±8 kg/m2) underwent clinical and biochemical examination and Doppler echocardiograms before and 5 years after LSG.Results. Pre-operatively, 78.4% of patients were hypertensive, 46.2% had diabetes, 73.1% MetS and 44.2% presented left ventricle hypertrophy (LVH), reflecting high cardio-metabolic risk. The patients reassessment was made 61.7±10.5 months after LSG, when a decrease in BMI of 21.9±10% was achieved (p<0.001). The prevalence of hypertension (64.7%), diabetes (32.7%) and MetS (28.8%) decreased compared to the pre-operative examination (p=0.019, p<0.001, p=0.036). An increase in left ventricle mass and left ventricle mass index (LVMI) (p<0.001) and in the prevalence of LVH (57.7%-p=0.001) was recorded. Patients were divided into two groups based on the decrease in LVMI (positive response-38.5%) or increase in LVMI post-surgery (negative response-61.5%), compared with pre-operative values. The group of patients with negative response had lost less weight (p=0.006), had a poor glycemic control (p=0.022), and higher systolic (p=0.004) and diastolic (p=0.030) pressure values compared to the first evaluation.Conclusion. The increase of LVMI after LSG indicates that this study should continue, including a larger number of patients. It is important to identify the factors that can predict an inappropriate response to surgery, in order to prevent and treat them.

Weight Outcomes

Background: Obesity is considered a global chronic disease requiring weight management through lifestyle modification, pharmacotherapy, or weight loss surgery. The dramatic increase in patients with severe obesity in Saudi Arabia is paralleled with those undergoing bariatric surgery. Although known to be beneficial in the short term, the long-term impacts of surgery within this group and the sustainability of weight loss after surgery remains unclear. Objectives: We aimed to assess the long-term weight outcomes after bariatric surgery. Setting: The study was conducted at King Khalid University Hospital (KKUH), King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia. Methods: An observational prospective cohort study on adult patients with severe obesity undergoing bariatric surgery (sleeve gastrectomy (SG) or Roux-en Y gastric bypass (RYGB)) during the period between 2009 and 2015 was conducted. Weight loss patterns were evaluated pre- and post-surgery through clinical and anthropometric assessments. Absolute weight loss was determined, and outcome variables: percent excess weight loss (%EWL), percent total weight loss (%TWL), and percent weight regain (%WR), were calculated. Statistical analysis using univariate and multivariate general linear modelling was carried out. Results: A total of 91 (46 males and 45 females) patients were included in the study, with the majority belonging to the SG group. Significant weight reductions were observed at 1 and 3 years of follow-up (p < 0.001) from baseline. The %EWL and %TWL were at their maximum at 3 years (72.4% and 75.8%) and were comparable between the SG and RYGB. Decrements in %EWL and %TWL and increases in %WR were seen from 3 years onwards from bariatric surgery until the study period ended. The yearly follow-up attrition rate was 20.8% at 1 year post-surgery, 26.4% at year 2, 31.8% at year 3, 47.3% at year 4, 62.6% at year 5, and 79.1% at end of study period (at year 6). Conclusion: The major challenge to the successful outcome of bariatric surgery is in maintaining weight loss in the long-term and minimizing weight regain. Factors such as the type of surgery and gender need to be considered before and after surgery, with an emphasis on the need for long-term follow-up to enssure the optimal benefits from this intervention.

Background: Bariatric surgery is the most effective current treatment option for patients with severe obesity. More children and adolescents are having surgery, many whose parents have also had surgery. The current study examines whether parental surgery status moderates the association between perceived social support, emotional eating, food addiction and weight loss following surgery, with those whose parents have had surgery evidencing a stronger relationship between the psychosocial factors and weight loss as compared to their peers. Methods: Participants were 228 children and adolescents undergoing sleeve gastrectomy between 2014 and 2019 at one institution. Children and adolescents completed self-report measures of perceived family social support, emotional eating, and food addiction at their pre-surgical psychological evaluation. Change in body mass index (BMI) from pre-surgery to 3, 6, and 12 months post-surgery was assessed at follow-up clinic visits. Parents reported their surgical status as having had surgery or not. Results: There were no differences in perceived family support, emotional eating, or food addiction symptoms between those whose parents had bariatric surgery and those whose parents did not. There were some moderating effects of parent surgery status on the relationship between social support, emotional eating/food addiction, and weight loss following surgery. Specifically, at 3 months post-surgery, higher change in BMI was associated with lower perceived family support only in those whose parents had not had surgery. More pre-surgical food addiction symptoms were associated with greater weight loss at 3 months for those whose parents had not had surgery, whereas this finding was true only for those whose parents had surgery at 12 months post-surgery. Conclusions: Children and adolescents whose parents have had bariatric surgery may have unique associations of psychosocial factors and weight loss. More research is needed to determine mechanisms of these relationships.

Objective: Existing studies of predictors of weight loss after bariatric surgery suffer from simplistic statistical methods and relatively short follow-up. We sought to determine predictors of long-term weight loss up to 9.6 years after bariatric surgery using data extracted from two electronic health records (EHR) systems and linear mixed effects models. Methods: Participants were selected from patients enrolled in the NUgene biorepository at either Northwestern Memorial HealthCare or NorthShore University HealthSystem. Individuals who had undergone Roux-en-Y gastric bypass (RNY) were identified through billing or surgical history procedure codes in the electronic health records (EHRs). All available weight measurements and dates were extracted from the EHR as well as surgery date. Sex, race/ethnicity, education, marital status, and height were taken from the NUgene intake questionnaire. SAS PROC MIXED was used to create linear mixed effects models to examine weight loss from 1- 9.6 years post-surgery. To examine overall weight loss and slope of weight regain, covariates and covariate interactions with time post-surgery were included in the mixed effects models. Results: 119 individuals from Northwestern and 43 individuals from NorthShore had undergone gastric bypass and had at least 1 weight measurement 1 year post-surgery. There were 3071 weight measurements which occurred at least 1 year post-surgery in the dataset; the median number of observations per person was 10 and the median weight loss represented by these measurements was 32.7% from pre-surgical weight. The regression model indicated that, on average, individuals experienced slight weight regain of about 0.8% of pre-surgical weight per year after their first year post-surgery. Over the 1- 10 years of follow up African Americans lost nearly 5 percentage points less weight than whites ( p =.0025) . People who were older and taller also experienced less percentage weight loss, and people with higher initial weights experienced a higher percentage weight loss (all p <.05), Older age was associated with significantly (p<0.05) slower weight regain after 1 year post-surgery. Discussion: EHR records from multiple institutions can be integrated to study outcomes after bariatric surgery. Demographic factors predict overall weight loss and a rate of weight regain after 1 year post RNY surgery. This information may be useful for both surgeons and prospective patients.

Post Bariatric Surgery

Introduction: The prevalence of obesity continues to rise since 1980. This obesity epidemic has been paralleled by a trend of reduced sleep duration and sleep quality throughout the years. However, there is limited research on the relation between sleep duration and quality and its association with weight loss maintenance. The purpose of this study was to examine the association between sleep duration and quality and weight status in post-bariatric surgery patients at 9-y post-surgery. We tested the hypothesis that participants’ post-surgical weight change would be related to sleep duration and quality at 9-y. Methods: Sleep data were collected on a subset of participants (mean body weight = 94.1 kg ± 18.9) enrolled in an ancillary study to the Longitudinal Assessment for Bariatric Surgery trial. Self-reported hours of sleep per night and overall sleep quality were assessed once, at the 9-y visit using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Results: Complete data were available on 14 participants (10 females and 4 males, age 52.1 ± 15.6 y), current weight 94 kg ± 18.9. Average total weight loss from pre-surgery was 28.5% ± 10.6, with an average weight gain of 0.3 ± 6.2 % over the last 2 y of follow-up. Participants reported average sleep duration of 6.8 ± 2.0 h/night at the 9-y evaluation visit and an average score of 7.9 ± 3.7 on the PSQI. There was no relation between sleep duration and current weight or percent weight change after maximum weight loss, which occurred around 2-y post-surgery. However, there were trends for an association between sleep quality and percent weight change after maximum weight loss (p=0.057) and percent weight change in the last 2-y of follow-up (p=0.066). In general, participants who lost more weight over the last 2 y of the study had lower scores on the PSQI, indicating better quality of sleep. Conclusion: Our results showed no association between sleep quality or duration and long-term changes in weight for patients who underwent bariatric surgery. However, those with better sleep quality tended to have more beneficial changes in weight over the latest 2-y. It is important to note that this study cannot address causality and whether improved weight influenced sleep quality or whether sleep quality influenced weight change. Further studies should examine the temporality of these association. Sleep quality may be an important sleep metric to consider for long-term weight loss maintenance.

Background: Obesity is a chronic inflammatory condition associated with increased circulating levels of C-reactive protein (CRP). Bariatric surgery has been reported to be effective in improving both inflammatory and liver status. Our aims were to elucidate the relationships between pre-surgery high sensitivity-CRP (hs-CRP) values and post-surgery weight loss and liver steatosis and fibrosis in patients with severe obesity undergoing Roux-en-Y gastric bypass. Methods: We conducted an observational prospective study on 90 individuals with morbid obesity, who underwent gastric bypass. Anthropometric indices, laboratory assessment (lipid panel, glycemic status, liver enzymes, and hs-CRP), liver stiffness and steatosis were evaluated at baseline and 6-months after surgery. Results: There was a significant post-surgery reduction in all the anthropometric variables, with an average weight loss of 33.93 ± 11.79 kg; the mean percentage of total weight loss (TWL) was 27.96 ± 6.43%. Liver elasticity was significantly reduced (from 6.1 ± 1.25 to 5.42 ± 1.52 kPa; p = 0.002), as well as liver aminotransferases, nonalcoholic fatty liver disease fibrosis score (NFS) and the grade of steatosis. Serum hs-CRP levels significantly reduced (from 9.26 ± 8.45 to 3.29 ± 4.41 mg/L; p < 0.001). The correlations between hs-CRP levels and liver fibrosis (elastography), steatosis (ultrasonography), fibrosis-4 index, NFS, and surgery success rate were not significant. Regression analyses showed that serum hs-CRP levels were not predictive of liver status and success rate after surgery in both unadjusted and adjusted models. Conclusions: In patients with morbid obesity, bariatric surgery caused a significant decrease in hs-CRP levels, liver stiffness and steatosis. Baseline hs-CRP values did not predict the weight-loss success rate and post-surgery liver status.

Nutritional Studies

There are few long-term nutritional studies in subjects undergoing bariatric surgery that have assessed weight regain and nutritional deficiencies. In this study, we report data 8 years after surgery on weight loss, use of dietary supplements and deficit of micronutrients in a cohort of patients from five centres in central and northern Italy. The study group consisted of 52 subjects (age: 38.1 ± 10.6 y, 42 females): 16 patients had Roux-en-Y gastric bypass (RYGB), 25 patients had sleeve gastrectomy (SG) and 11 subjects had adjustable gastric banding (AGB). All three bariatric procedures led to sustained weight loss: the average percentage excess weight loss, defined as weight loss divided by excess weight based on ideal body weight, was 60.6% ± 32.3. Despite good adherence to prescribed supplements, 80.7% of subjects (72.7%, AGB; 76.7%, SG; 93.8 %, RYGB) reported at least one nutritional deficiency: iron (F 64.3% vs. M 30%), vitamin B12 (F 16.6% vs. M 10%), calcium (F 33.3% vs. M 0%) and vitamin D (F 38.1% vs. M 60%). Long-term nutritional deficiencies were greater than the general population among men for iron and among women for vitamin B12.

Abstract Background Bariatric surgery is an effective treatment for the obesity epidemic, but the poor attendance and adherence rates of post-surgery recommendations threaten treatment effectiveness and health outcomes. Preoperatively, we investigated the unique contributions of clinical (e.g., medical and psychiatric comorbidities), sociodemographic (e.g., sex, age, and educational level), and psychopathological variables (e.g., binge eating severity, the general level of psychopathological distress, and alexithymia traits) on differing dimensions of adherence in a group of patients seeking bariatric surgery. Methods The final sample consisted of 501 patients (346 women). All participants underwent a full psychiatric interview. Self-report questionnaires were used to assess psychopathology, binge eating severity, alexithymia, and three aspects of adherence: knowledge, attitude, and barriers to medical recommendations. Results Attitude to adherence was associated with alexithymia (β = ˗2.228; p < 0.001) and binge eating disorder (β = 0.103; p = 0.047). The knowledge subscale was related to medical comorbidity (β = 0.113; p = 0.012) and alexithymia (β = −2.256; p < 0.001); with age (β = 0.161; p = 0.002) and psychiatric comorbidity (β =0.107; p = 0.021) manifesting in the barrier subscale. Conclusion We demonstrated that alexithymia and psychiatric and eating disorders impaired adherence reducing attitude and knowledge of treatment and increasing the barriers. Both patient and doctor can benefit from measuring adherence prior to surgery, with a qualitative approach shedding light on the status of adherence prior to the postsurgical phase when the damage regarding adherence is, already, done.
