The Effect of an Education Module to Reduce Weight Bias among Medical Centers Employees: A Randomized Controlled Trial.

INTRODUCTION: Weight bias, stigma, and discrimination are common among healthcare professionals. We aimed to evaluate whether an online education module affects weight bias and knowledge about obesity in a private medical center setting. METHODS: An open-label randomized controlled trial was conducted among all employees of a chain of private medical centers in Israel (n = 3,290). Employees who confirmed their consent to participate in the study were randomized into intervention or control (i.e., "no intervention") arms. The study intervention was an online 15-min educational module that included obesity, weight bias, stigma, and discrimination information. Questionnaires on Anti-Fat Attitudes (AFA), fat-phobia scale (F-scale), and beliefs about the causes of obesity were answered at baseline (i.e., right before the intervention), 7 days, and 30 days post-intervention. RESULTS: A total of 506, 230, and 145 employees responded to the baseline, 7-day, and 30-day post-intervention questionnaires, respectively. Mean participant age was 43.3 ± 11.6 years, 84.6% were women, and 67.4% held an academic degree. Mean F-scale scores and percentage of participants with above-average fat-phobic attitudes (≥3.6) significantly decreased only within the intervention group over time (p ≤ 0.042). However, no significant differences between groups over time were observed for AFA scores or factors beliefs to cause obesity. CONCLUSIONS: A single exposure to an online education module on weight bias and knowledge about obesity may confer only a modest short-term improvement in medical center employees' fat-phobic attitudes toward people with obesity. Future studies should examine if reexposure to such intervention could impact weight bias, stigma, and discrimination among medical center staff in the long-term.

Health Status, Eating, and Lifestyle Habits in the Long Term Following Sleeve Gastrectomy.

INTRODUCTION: Sleeve gastrectomy (SG) is an established bariatric procedure. However, long-term data on eating and lifestyle behaviors and their effect on weight outcomes are scarce. Therefore, this study aimed to examine these long-term behaviors and their associations to weight outcomes following SG. METHODS: A long-term follow-up study (>5 years post-surgery) of 266 adult patients admitted to a primary SG surgery during 2008-2012 and who participated in a pre-surgery study was conducted. Data on pre-surgery demographics, anthropometrics, and medical status were obtained from the patients' medical records. Data on long-term health status, anthropometrics, lifestyle and eating habits, eating pathologies, follow-up regime, and satisfaction from the surgery were collected by an interview phone calls according to a structured questionnaire. RESULTS: Data of 169 patients were available before and 7.8±1.0 years post-SG. Their baseline mean age was 41.8±11.3 years, and 71.6% of them were females. The mean post-surgery excess weight loss (EWL) was 53.2±31.2%, and 54.2% had EWL of ≥50%. Eating 3-6 meals per day, not having the urge to eat after dinner, separating liquids from solids, avoiding carbonated beverages, and performing physical activity were related to better weight-loss outcomes (P≤0.026). However, frequent need for eating sweets, binge eating, and feeling guilty or sad after eating were related to worse weight-loss outcomes (P≤0.010). Furthermore, only a minority reported taking a multivitamin and participating in follow-up meetings after more than 1 year since the surgery (≤21.3%). CONCLUSIONS: In the long term following SG, approximately half achieved EWL of ≥50%, and physical activity, certain eating patterns, and eating pathologies were related to weight outcomes.

Nutritional status following One Anastomosis Gastric Bypass.

BACKGROUND & AIMS: One Anastomosis Gastric Bypass (OAGB) has been accepted as an effective treatment for morbid obesity. However, data are scarce regarding nutritional implications of this procedure. Thus, our aim was to describe the health and nutritional status 12-20 months following OAGB surgery. METHODS: A prospective cohort study on patients who underwent OAGB surgery from January 2016 to May 2017 in a large, multi-disciplinary, bariatric clinic. Pre-surgery data including demographic details, anthropometrics, co-morbidities, blood tests and lifestyle habits were obtained from the patients' medical records. Follow-up evaluations were performed 12-20 months post-surgery and data collected included anthropometrics, blood tests, eating and lifestyle parameters, adherence to follow-up regime and gastrointestinal (GI) related side effects. In addition, patients were asked to rate their overall state of health (OSH) from 0 to 100 using a visual analogue scale (VAS). RESULTS: Eighty-six OAGB patients (72.1% women) were tested 14.7 ± 2.0 months post-operatively. Their mean age and BMI preoperatively were 46.1 ± 11.4 years and 42.0 ± 4.9 kg/m2, respectively. The mean % excess weight loss at 12-20 months postoperatively was 88.4 ± 19.3%. Lipid and glucose profiles were significantly improved at 12-20 months postoperatively compared to baseline (P < 0.001 for all). Relatively high proportions of nutritional deficiencies were found pre-operatively and postoperatively for iron (33.9% vs. 23.7%, P = 0.238), folate (30.9% vs. 11.8%, P = 0.004), vitamin D (56.6% vs. 17.0%, P < 0.001) and hemoglobin (16.7% vs. 42.9%, P < 0.001). Postoperatively, most participants reported taking multivitamin, calcium, vitamin D and vitamin B12 supplementation (≥62.8%), having participated in at least 6 meetings with a dietitian (51.8%) and presently doing physical activity (69.4%). The mean postoperative OSH VAS score was 88.2 ± 12.3, but most participants reported on flatulence (67.4%) and some reported on diarrhea (25.6%) as GI side effects of the surgery. CONCLUSIONS: Substantial improvements in health and anthropometric parameters are found in the short-term follow-up after OAGB, with a satisfactory reported quality of life and adherence to recommendations. However, a high prevalence of some GI side effects, nutritional deficiencies and specially anemia is a matter of concern.

The Effect of Pre-Surgery Information Online Lecture on Nutrition Knowledge and Anxiety Among Bariatric Surgery Candidates.

INTRODUCTION: Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS. METHODS: An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records. RESULTS: Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 ± 11.4 years and 41.3 ± 4.9 kg/m2, respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre-BS committee (P ≤ 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time-points (P < 0.001 for all). CONCLUSION: Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647.

Health and Nutritional Status of Vegetarian Candidates for Bariatric Surgery and Practical Recommendations.

INTRODUCTION: Data on vegetarianism and bariatric surgery (BS) are scarce. We herein describe the health and nutritional status of vegetarian patients who plan to undergo BS and propose combined recommendations for vegetarian patients who undergo BS, based on our clinical experience and current scientific literature in both nutrition fields. METHODS: Cross-sectional analysis of a prospectively maintained database of all primary laparoscopic sleeve gastrectomies (LSG) performed at a bariatric center of excellence between January 2014 and November 2016 was carried out querying patients who declared a vegetarian or vegan lifestyle before surgery. Preoperative data collected included demographics, anthropometrics, dietary patterns, supplementation use, physical activity, smoking habits, co-morbidities, and blood tests. Each vegetarian was matched to five different omnivores based on age, gender, and BMI. RESULTS: During the study period, 1470 patients underwent primary LSG surgery (63.7% females). Twenty-one declared a vegetarian or vegan lifestyle (1.4%) pre-surgery. Most were classified as lacto-ovo (57.1%) and were driven from ethical reasons (85.7%). No differences were found between vegetarian and omnivore LSG candidates regarding co-morbidities and nutritional deficiencies, except for lower prevalence of impaired fasting glucose (14.3 vs. 47.1%;P = 0.007), lower ferritin levels (54.3 ± 50.5 vs. 96.8 ± 121.8 ng/ml; P = 0.052) and higher transferrin levels (313.9 ± 42.7 vs. 278.4 ± 40.4 mg/dl; P = 0.009) among the vegetarian cohort. Preoperative use of vitamin B12 and iron supplementation was higher among vegetarian LSG candidates than their omnivore counterparts (57.1 vs. 6.7%;P < 0.001 and 23.8 vs. 6.7%; P = 0.015, respectively). CONCLUSIONS: Vegetarians have comparable health status and nutritional deficiencies, lower iron stores, and higher supplementation use before surgery compared to omnivore LSG candidates.

Poor Health Behaviors Prior to Laparoscopic Sleeve Gastrectomy Surgery.

INTRODUCTION: Identifying eating and lifestyle behaviors prior to bariatric surgery may assist in better selecting and preparing patients and might lead to improved success rate. The current study aimed to assess eating behaviors and lifestyle trends among laparoscopic sleeve gastrectomy (LSG) candidates and to compare those trends between genders. METHODS: This descriptive study was conducted in the bariatric clinic at the Haifa Assuta Medical Center. Data was gathered from medical records of LSG candidates that were evaluated before surgery in our institution between 2008 and 2011. The data included demographics, comorbidities, anthropometrics, weight management history, and lifestyle parameters. Eating pattern and eating habits were determined by eating habits questionnaires. RESULTS: A total of 266 LSG surgery candidates (71.4 % female) with an average age of 40.7 ± 10.9 years and pre-surgery BMI of 42.4 ± 4.8 kg/m2 were studied. More than half of the patients have family history of obesity and their onset of obesity was before the age of 18 years (54.5 and 57.9 %, respectively). Most of the patients reported on poor eating habits and sedentary lifestyle: 65.1 % do not eat regular meals, 70.3 % skip over breakfast, 61.9 % presented loss of control eating, 45 % frequently consume sweets, and 80.1 % were classified as none active. There were no differences in eating patterns or lifestyle parameters between genders. CONCLUSION: High occurrence of unhealthy eating habits and a non-active lifestyle were detected in morbid obese candidates for LSG surgery. More efforts should be directed towards nutritional and lifestyle education prior to the surgery.
