How to get back on track? Experiences of patients and healthcare professionals regarding weight recurrence and needs for an intervention after bariatric-metabolic surgery.

Background: Multidisciplinary lifestyle interventions are recommended as a first step in treating weight recurrence after bariatric-metabolic surgery (BMS). However, little is known about the experience of patients and healthcare professionals (HCP) with these interventions and how they should be tailored to the patients' needs. The aim of this study was to gain more insight into the experiences and needs of patients and HCP regarding weight recurrence after BMS and an intervention to get Back on Track. In addition, attitudes towards integrating e-Health into the care program were explored. Methods: A qualitative process evaluation of an intervention for weight recurrence, the Back on Track (BoT), was conducted by means of in-depth interviews and focus groups with 19 stakeholders, including patients and HCP involved in BoT. Interviews were transcribed verbatim. Data were analyzed through thematic analysis. Results: Patients and HCP reported a wide array of causes of weight recurrence. Patients found it difficult to decide when weight recurrence is problematic and when they should ask for help. Patients reported feeling like the exception and ashamed, therefore experiencing a high threshold to seek help. E-Health was seen as a promising way to improve tailoring, screening, autonomy for the patient, and accessible contact. Conclusion: Patients should be adequately counselled on weight recurrence after BMS and the importance of intervening early. It is important to lower the threshold for seeking help. For example by offering more long-term standard care or by adding e-Health to the intervention.

Five-year weight loss, physical activity, and eating style trajectories after bariatric surgery.

BACKGROUND: Little research has taken individual variability in weight loss into account. Furthermore, physical activity (PA) and eating style (ES) have been linked only sporadically to weight loss longitudinally. OBJECTIVES: Identify and describe latent classes of weight loss, change of PA, and change of ES up to 5 years after surgery and investigate whether these trajectories are interrelated. SETTING: Multicenter outpatient clinic. METHODS: This is a retrospective study of data collected during standard treatment before and up to 5 years after surgery. Latent class growth analysis was used to identify trajectories of weight loss (percent total weight loss), PA (Baecke questionnaire), and ES (Dutch Eating Behavior Questionnaire). RESULTS: A total of 2785 patients were included. Follow-up rate was 84% at 1 year and 34% at 5 years. Analyses revealed 5 weight loss trajectories. Most patients followed an average, fairly stable weight loss trajectory (48%) or an above-average partial-regain trajectory (36%). Other patients followed a low-responder trajectory (9%), a rapid weight loss and weight regain trajectory (6%), or a continued weight loss trajectory (2%). Patients in the most favorable weight loss trajectory were more likely to also follow the most favorable ES trajectories. Patients following the most unfavorable weight loss trajectory were never also in the PA trajectory with an initial great increase in PA. CONCLUSION: This study distinguishes demographic and behavioral factors that may influence long-term weight loss trajectories after bariatric surgery. Trajectories varied mainly in magnitude and less in the pattern of weight loss over time, suggesting that very deviant patterns are rare.

Health-related quality of life after sleeve gastrectomy equal to Roux-en-Y gastric bypass patients?

PURPOSE: Sleeve gastrectomy (SG) is the most popular type of bariatric surgery. It has often been compared to Roux-en-Y gastric bypass (RYGB) in terms of clinical outcomes. However, health-related quality of life (HRQoL) has been sparsely studied after SG. The goal was to study HRQoL after SG using a generic (RAND-36) and an obesity-specific (impact of weight on quality of life-lite, IWQOL-lite) questionnaire and to compare the results with RYGB. METHODS: HRQoL and weight were measured before and 9, 15, and 24 months after surgery. RAND-36 physical health summary (PHS) and mental health summary (MHS), and IWQOL-lite total score were calculated. A mixed model analysis was conducted to study the change in HRQoL and compare SG with RYGB. RESULTS: A total of 219 patients (8.7%) underwent a SG and 2309 patients (91.3%) a RYGB. PHS, MHS, and IWQOL-lite significantly improved after SG when comparing baseline to all follow-up moments (p < 0.001 in all). There were no significant differences when comparing SG with RYGB: change in PHS (ß - 0.10, 95% CI - 1.24 to 1.04, p = 0.861), MHS (ß - 0.51, 95% CI - 1.56 to 0.52, p = 0.330), and IWQOL-lite (ß 0.310, 95% CI - 0.85 to 1.47, p = 0.601). CONCLUSION: HRQoL significantly improved after SG. In the included populations, weight loss was comparable and the extent to which HRQoL improved did not differ between SG and RYGB, when measured with the RAND-36 or IWQOL-lite. This might be partly caused by the fact that these questionnaires do not assess specific bariatric HRQoL and/or complaints.

Definitions of Long-Term Weight Regain and Their Associations with Clinical Outcomes.

INTRODUCTION: The prevalence and clinical significance of weight regain after bariatric surgery remains largely unclear due to the lack of a standardized definition of significant weight regain. The development of a clinically relevant definition of weight regain requires a better understanding of its clinical significance. OBJECTIVES: To assess rates of weight regain 5 years after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), applying six definitions and investigating their association with clinical outcomes. METHODS: Patients were followed up until 5 years after surgery and weight regain was calculated. Regression techniques were used to assess the association of weight regain with health-related quality of life (HRQoL) and the presence of comorbidities. RESULTS: A total of 868 patients participated in the study, with a mean age of 46.6 (± 10.4) years, of which 79% were female. The average preoperative BMI was 44.8 (± 5.9) kg/m2 and the total maximum weight loss was 32% (± 8%). Eighty-seven percent experienced any regain. Significant weight regain rates ranged from 16 to 37% depending on the definition. Three weight regain definitions were associated with deterioration in physical HRQoL (p < 0.05), while associations between definitions of weight regain and the presence of comorbidities 5 years after surgery were not significant. CONCLUSION: These results indicate that identifying one single categorical definition of clinically significant weight regain is difficult. Additional research into the clinical significance of weight regain is needed to inform the development of a standardized definition that includes all dimensions of surgery success: weight, HRQoL, and comorbidity remission.

Mirror exposure to increase body satisfaction: Should we guide the focus of attention towards positively or negatively evaluated body parts?

BACKGROUND AND OBJECTIVES: Though there is some evidence that body exposure increases body satisfaction, it is still unclear why exposure works and how attention should be guided during exposure. This pilot study manipulates the focus of attention during body exposure. METHODS: Female participants high in body dissatisfaction were randomly assigned to an exposure intervention that exclusively focused on self-defined attractive (n = 11) or self-defined unattractive (n = 11) body parts. Both interventions consisted of five exposure sessions and homework. Outcome and process of change were studied. RESULTS: Both types of exposure were equally effective and led to significant improvements in body satisfaction, body checking, body concerns, body avoidance and mood at post-test. Improvements for body satisfaction and mood were maintained at follow-up while body shape concerns and body checking still improved between post-test and follow-up. Body avoidance improvements were maintained for the positive exposure while the negative exposure tended to further decrease long-term body avoidance at follow-up.. The 'positive' exposure induced positive feelings during all exposure sessions while the 'negative' exposure initially induced a worsening of feelings but feelings started to improve after some sessions. The most unattractive body part was rated increasingly attractive in both conditions though this increase was significantly larger in the negative compared to the positive exposure condition. LIMITATIONS: The sample size was small and non-clinical. CONCLUSIONS: Both types of exposure might be effective and clinically useful. Negative exposure is emotionally hard but might be significantly more effective in increasing the perceived attractiveness of loathed body parts and in decreasing avoidance behavior.
