Eating self-efficacy as predictor of long-term weight loss and obesity-specific quality of life after sleeve gastrectomy: A prospective cohort study

Under embargo until: 15.12.2019Background: A person's confidence to control eating, eating self-efficacy (ESE), has been identified as a target for long-term weight management in nonsurgical weight loss interventions, but has to a limited extent been studied after bariatric surgery. Objective: We investigated the association between ESE, weight loss, and obesity-specific quality of life (QOL) after sleeve gastrectomy (SG). Setting: A single-center longitudinal study. Methods: Data from adult patients were collected before SG, and at mean 16 months (±standard deviation 4 mo) and 55 (±4) months postoperatively. ESE was measured by the Weight Efficacy Lifestyle Questionnaire Short-Form. Multiple regression analyses were performed with excess body mass index loss (%EBMIL) and obesity-specific QOL as dependent variables. Age, sex, and other preoperative values were covariates in all models. Results: Of 114 preoperative patients, 91 (80%) and 84 (74%) were available for follow-up 16 and 55 months after SG, respectively. Mean %EBMIL from baseline to 16 and 55 months was 76% (95% confidence interval: 71.9, 79.6) and 67% (95% confidence interval: 61.9, 72.2), respectively. Preoperative ESE scores improved significantly at both 16 and 55 months (P = .002) but did not predict postoperative %EBMIL or QOL at 55 months (β = −.08, P = .485). Greater change in ESE from 0 to 16 months predicted higher %EBMIL (β = .34, P = .013) at 55 months, and improvements in ESE from 0 to 55 months were significantly associated with higher %EBMIL (β = .46, P = .001) and obesity-specific QOL (β = .50, P < .001) 55 months after SG. Conclusion: Significant improvements in ESE were seen at 16 months, and remained high at 55 months after SG in this cohort. Patients who improved their ESE the most also experienced the highest weight loss and obesity-specific QOL 5 years postoperatively. Future research should address whether enhancement of ESE corresponds to sustained improvements in eating behavior after bariatric surgery.acceptedVersio

Short-term effects of Vertical sleeve gastrectomy and Roux-en-Y gastric bypass on glucose homeostasis

The objective of this study was to compare the biochemical changes related to glucose tolerance and lipid metabolism in non-diabetic patients shortly after vertical sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). Non-diabetic women and men with morbid obesity were studied the day before and six days after SG (N = 15) or RYGB (N = 16). Patients completed an oral glucose tolerance test (OGTT; 75 g glucose) at both visits. SG and RYGB similarly improved fasting glucose homeostasis six days after surgery, with reduced glucose and insulin concentrations. The OGTT revealed differences between the two surgery groups that were not evident from the fasting serum concentrations. Postprandial (120 min) glucose and insulin concentrations were lower after RYGB but not after SG, whereas concentrations of glucagon-like peptide-1, peptide YY, glucagon and non-esterified fatty acids were elevated after both SG and RYGB. Fasting triacylglycerol concentration did not change after surgery, but concentrations of high density lipoprotein and low density lipoprotein cholesterols were reduced in both surgery groups, with no differences between the groups. To conclude, RYGB induced a more pronounced improvement in postprandial glucose homeostasis relative to SG, possibly due to improved insulin sensitivity rather than augmented insulin concentration.publishedVersio

Seven-year trajectories of body weight, quality of life and comorbidities following Roux-en-Y gastric bypass and sleeve gastrectomy

Background/objectives There is limited long-term data comparing the outcomes of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for severe obesity, both with respect to body weight, quality of life (QOL) and comorbidities. We aimed to determine 7-year trajectories of body mass index (BMI), QOL, obesity-related comorbidities, biomarkers of glucose and lipid metabolism, and early major complications after SG and RYGB. Subjects/methods Patients scheduled for bariatric surgery at two Norwegian hospitals, preferentially performing either SG or RYGB, were included consecutively from September 2011 to February 2015. Data was collected prospectively before and up to 7 years after surgery. Obesity-specific, generic and overall QOL were measured by the Impact of Weight on Quality of Life-Lite, Short-Form 36 and Cantril’s ladder, respectively. Comorbidities were assessed by clinical examination, registration of medication and analysis of glucose and lipid biomarkers. Outcomes were examined with linear mixed effect models and relative risk estimates. Results Of 580 included patients, 543 (75% women, mean age 42.3 years, mean baseline BMI 43.0 kg/m2) were operated (376 SG and 167 RYGB). With 84.2% of participants evaluable after 5–7 years, model-based percent total weight-loss (%TWL) at 7 years was 23.4 after SG versus 27.3 after RYGB (difference 3.9%, p = 0.001). All levels of QOL improved similarly after the two surgical procedures but remained below reference data from the general population at all timepoints. Remission rates for type 2 diabetes, dyslipidemia, obstructive sleep-apnea and gastroesophageal reflux disease (GERD) as well as the rate of de novo GERD significantly favored RYGB. SG had fewer major early complications, but more minor and major late complications combined over follow-up. Conclusion In routine health care, both SG and RYGB are safe procedures with significant long-term weight-loss, improvement of QOL and amelioration of comorbidities. Long-term weight-loss and remission rates of main obesity-related comorbidities were higher after RYGB.publishedVersio

Long-term outcomes after vertical sleeve gastrectomy for severe obesity

Background: Severe obesity is a chronic disease entailed by increased risk of obesityrelated comorbidities, impaired quality of life (QOL) and early death. Causes and consequences are multifactorial and reflect an interplay between biological, psychosocial and environmental factors. Bariatric surgery has evolved as a treatment option, providing weight loss and improvements in health. Vertical sleeve gastrectomy (VSG) is the latest and most frequently performed bariatric procedure worldwide, but data on long-term efficacy is scarcely reported. Little is known about factors that can explain the variability in long-term outcome after bariatric surgery. It is necessary to identify predictors of sustained weight loss and QOL improvements for a tailored patient-centric support. Objectives: The main objective of studies I-III was to report long-term outcomes in terms of weight, obesity-related comorbidities and QOL after VSG. Firstly, we report five-year complication and revision rates, weight loss and changes in comorbidities (primarily type 2 diabetes, hypertension and gastroesophageal reflux disease (GERD)). Secondly, previous studies found that self-efficacy may be a predictor of behavioral change and long-term health outcome. We therefor assessed the association between self-efficacy related to eating, weight loss and obesity-specific QOL five years after VSG. Thirdly, long-term reports on QOL after VSG are particularly limited. We assessed QOL broadly, covering obesity-specific and generic health-related QOL, as well as overall life satisfaction, and examined the association between weight loss and all levels of QOL five years after VSG. Methods: Demographic, clinical and patient-reported data from three separate patient cohorts was collected prospectively up to five years after VSG. In studies I and III, the data was extracted from the local obesity surgery registry in Førde Central Hospital, while the data in study II was collected at Voss Hospital. Eating self-efficacy was measured by the Weight Efficacy Lifestyle Questionnaire Short-Form. Health-related QOL and overall life satisfaction were measured by the Impact of Weight on Quality of Life-Lite, the Obesity-Related Problem Scale, Short-Form-36 and Cantril’s ladder. All outcomes on QOL at five years were compared to population norms. Results: In studies I-III, 168, 114 and 127 VSG patients were included with five-year participation rates of 82, 74 and 64%, respectively. Mean weight loss was profound and significant in all cohorts from baseline to five years, but modest, significant weight regain was seen between one/two and five years after VSG. In study I, complication and revision rates were low, and most obesity-related comorbidities significantly improved from baseline to five years, with a notable exception of GERD. The prevalence of preoperative GERD increased from 12 to 35% at five years after surgery. Remission rates of type 2 diabetes and hypertension were 63 and 60% at five years, respectively. In study II, changes in eating self-efficacy from baseline to one year predicted weight loss at five years, as opposed to preoperative eating self-efficacy. Improvement in eating self-efficacy from baseline to five years was associated with greater weight loss and better obesity-specific QOL at five years after surgery. In study III, clinically and statistically significant improvements from baseline to five years occurred in all three levels of QOL, with significant yet modest deteriorations seen between one and five years after surgery. Greater weight loss five years after surgery was significantly associated with improvements in obesity-specific QOL and physical health-related QOL, but not with mental health-related QOL and overall life satisfaction. All mean scores on QOL at five years after VSG were below population norms. Conclusions: VSG is a safe and effective treatment of severe obesity. A majority of patients studied obtained enduring weight loss and improvements in health and QOL. Particular attention needs to be paid to symptoms of GERD after VSG. Still, over one third of patients experienced subsequent weight regain of 10 kg or more, and average QOL deteriorated between one or two and five years after VSG. Hence, an important minority of patients report less beneficial long-term outcomes after VSG, and some patients exhibit further deterioration in QOL compared to preoperative reports. The observed associations between eating self-efficacy, long-term weight loss and QOL, may inform tailored patient support following bariatric surgery

Translation, adaptation, validation and performance of the American Weight Efficacy Lifestyle Questionnaire Short Form (WEL-SF) to a Norwegian version: a cross-sectional study

Background. Researchers have emphasized a need to identify predictors that can explain the variability in weight management after bariatric surgery. Eating self-efficacy has demonstrated predictive impact on patients’ adherence to recommended eating habits following multidisciplinary treatment programs, but has to a limited extent been subject for research after bariatric surgery. Recently an American short form version (WEL-SF) of the commonly used Weight Efficacy Lifestyle Questionnaire (WEL) was available for research and clinical purposes. Objectives. We intended to translate and culturally adapt the WEL-SF to Norwegian conditions, and to evaluate the new versions’ psychometrical properties in a Norwegian population of morbidly obese patients eligible for bariatric surgery. Design. Cross-sectional Methods. A total of 225 outpatients selected for Laparoscopic sleeve gastrectomy (LSG) were recruited; 114 non-operated and 111 operated patients, respectively. The questionnaire was translated through forward and backward procedures. Structural properties were assessed performing principal component analysis (PCA), correlation and regression analysis were conducted to evaluate convergent validity and sensitivity, respectively. Data was assessed by mean, median, item response, missing values, floor- and ceiling effect, Cronbach’s alpha and alpha if item deleted. Results. The PCA resulted in one factor with eigenvalue > 1, explaining 63.0% of the variability. The WEL-SF sum scores were positively correlated with the Self-efficacy and quality of life instruments (p < 0.001). The WEL-SF was associated with body mass index (BMI) (p < 0.001) and changes in BMI (p = 0.026). A very high item response was obtained with only one missing value (0.4%). The ceiling effect was in average 0.9 and 17.1% in the non-operated and operated sample, respectively. Strong internal consistency (r = 0.92) was obtained, and Cronbach’s alpha remained high (0.86–0.92) if single items were deleted. Conclusion. The Norwegian version of WEL-SF appears to be a valid questionnaire on eating self-efficacy, with acceptable psychometrical properties in a population of morbidly obese patients

Educating the nurses of tomorrow: exploring first-year nursing students’ reflections on a one-week senior peer-mentor supervised inspiration practice in nursing homes

Abstract Background Worldwide, the healthcare system stresses a severe deficit of nurses because of elevated levels of work-induced stress, burnout and turnover rates, as well as the ageing of the nursing workforce. The diminishing number of nursing students opting for a career in nursing older people has exacerbated this shortage. A determining factor in the choice of a career within the field of residential care for nursing students is educational institutions offering students learning opportunities with positive learning experiences. Therefore, educational institutions must develop programmes that employ student active learning methods during clinical periods. Although much focus has been given to the development of new educational programs, insufficient consideration has been given to the value of peer mentoring and students’ interactions during the clinical placement at nursing homes. The aim of the present study is to explore first-year nursing students’ perceptions and experiences with peer mentoring as an educational model during their inspiration practice week at nursing home. Methods The study employed a qualitative exploratory and descriptive research design. Data collection took place in October 2022 using focus group interviews. A total of 53 students in their first year of the bachelor’s programme at the Oslo Metropolitan University participated in eight focus group interviews. The data were analysed following the principles of inductive content analysis. Results The analysis resulted in one main category, ‘Being inspired—keep learning and moving forward’, representing first-year nursing students’ common perceptions of being mentored by third-year students. The main category is supported by two categories: ‘Closeness to the mentor’ and ‘Confidence in mentors’ professional knowledge and teaching and supervision methods’, which are interpreted as the drivers that enabled first-year students to learn more about nurses’ roles and responsibilities in the nursing home. Conclusion Mentorship enhances the learning transfer from third-year nursing students over to first-year nursing students by providing them with real-world exposure and guidance from their more experienced peers. This hands-on approach allows them to bridge the gap between theory and practice more effectively, boosting first-year nursing students’ confidence and competence in nursing and caring for older people living in nursing homes

Eating self-efficacy as predictor of long-term weight loss and obesity-specific quality of life after sleeve gastrectomy: A prospective cohort study

Background: A person's confidence to control eating, eating self-efficacy (ESE), has been identified as a target for long-term weight management in nonsurgical weight loss interventions, but has to a limited extent been studied after bariatric surgery. Objective: We investigated the association between ESE, weight loss, and obesity-specific quality of life (QOL) after sleeve gastrectomy (SG). Setting: A single-center longitudinal study. Methods: Data from adult patients were collected before SG, and at mean 16 months (±standard deviation 4 mo) and 55 (±4) months postoperatively. ESE was measured by the Weight Efficacy Lifestyle Questionnaire Short-Form. Multiple regression analyses were performed with excess body mass index loss (%EBMIL) and obesity-specific QOL as dependent variables. Age, sex, and other preoperative values were covariates in all models. Results: Of 114 preoperative patients, 91 (80%) and 84 (74%) were available for follow-up 16 and 55 months after SG, respectively. Mean %EBMIL from baseline to 16 and 55 months was 76% (95% confidence interval: 71.9, 79.6) and 67% (95% confidence interval: 61.9, 72.2), respectively. Preoperative ESE scores improved significantly at both 16 and 55 months (P = .002) but did not predict postoperative %EBMIL or QOL at 55 months (β = −.08, P = .485). Greater change in ESE from 0 to 16 months predicted higher %EBMIL (β = .34, P = .013) at 55 months, and improvements in ESE from 0 to 55 months were significantly associated with higher %EBMIL (β = .46, P = .001) and obesity-specific QOL (β = .50, P < .001) 55 months after SG. Conclusion: Significant improvements in ESE were seen at 16 months, and remained high at 55 months after SG in this cohort. Patients who improved their ESE the most also experienced the highest weight loss and obesity-specific QOL 5 years postoperatively. Future research should address whether enhancement of ESE corresponds to sustained improvements in eating behavior after bariatric surgery

Changes in quality of life 5 years after sleeve gastrectomy: A prospective cohort study

Objectives Sleeve gastrectomy (SG) is the most frequently performed bariatric surgery procedure worldwide, but reports on long-term quality of life (QOL) outcomes are scarce. We investigated 5-year trajectories in QOL and their associations with weight loss after SG. Design A prospective cohort study. Setting The study was conducted in a single Norwegian bariatric surgery centre. Participants Out of 150 operated patients, 127 were included. Mean age was 41 years, 68% were women and the follow-up rate at 1 year was 85% and 64% at 1 and 5 years, respectively. Outcome measures Data were collected preoperatively, and 1 and 5 years after surgery assessing three different levels of QOL. The main exposure was weight loss after SG, assessed as per cent excess body mass index (kg/m2) loss (%EBMIL). The Obesity-Related Problem (OP) scale was used to measure obesity-specific health-related QOL (HRQOL). Physical (PCS) and mental (MCS) composite summary scores of the Short Form 36 Health Survey were used to capture generic HRQOL and Cantril Ladder was used to assess overall QOL. Results All HRQOL/overall QOL measures significantly improved at 1 year, followed by modest decline from 1 to 5 years after surgery. Greater %EBMIL 5 years after surgery was significantly associated with improvements in OP and PCS scores, but not with MCS and Cantril Ladder scores. Although significant (p<0.001) and clinically relevant improvements in HRQOL/overall QOL outcomes were observed at 5 years, scores were still below the general population norms. Conclusion Most patients undergoing SG experience substantial weight loss accompanied by statistically significant and clinically relevant long-term improvements in HRQOL/overall QOL. However, an important minority of patients still report low HRQOL/overall QOL 5 years after SG. Further research should aim to identify other factors that contribute to impaired QOL after bariatric surgery, even in the presence of successful weight control

The impact of educational concerns and satisfaction on baccalaureate nursing students’ distress and quality of life during the Covid‑19 pandemic; a cross‑sectional study

Background High levels of psychological distress and poor overall quality of life (QOL) have been identified among nursing students during the COVID-19 pandemic. The pandemic necessitated improvised reconstructions of educational curriculums and restrictions in clinical placement and training at campuses, possibly reducing educational quality. Objectives We explored whether baccalaureate nursing students’ concerns and satisfaction with the educational curriculum, focusing on the conduct of clinical training, were associated with perceived psychological distress and overall QOL. Methods Baccalaureate nursing students (N=6088) from five Norwegian universities were invited to an internet-based, cross-sectional survey during the second wave of the pandemic. The survey included COVID-19 specific questions on health, education and clinical training, the Fear of COVID-19 scale (FCV-19S), The Hopkins Symptom Checklist (SCL-5) and overall QOL. Data from national surveys on satisfaction with the educational curriculum, before and during the pandemic were used for comparison. Results In total, 2605 (43%) students responded, of whom 1591 (61%) had been engaged in clinical training during the pandemic. Overall, 53% were either satisfied or fully satisfied with their educational curriculum, with the level of satisfaction being significantly lower than pre-pandemic reference values. Also, 79% were concerned or highly concerned about the educational quality. In multiple regression analyses for all students, lower levels of satisfaction and higher levels of quality concerns were associated with worse SCL-5 scores. Furthermore, satisfaction with the educational curriculum was positively associated with overall QOL. For students engaged in clinical training, only concerns about infecting others were additionally associated with psychological distress. None of the items related to clinical training were associated with overall QOL. Conclusion Nursing students’ educational satisfaction and quality concerns may significantly impact perceived psychological distress and overall QOL during a pandemic. However, with necessary adaptations implemented, concerns regarding the conduct of clinical training account for little of these associations
