Abstract
OBJECTIVE This scoping review will evaluate the current published literature on decision-making in obesity management. INTRODUCTION Obesity is increasing in incidence worldwide. Although indications have been established for a variety of available treatment modalities, treatment selection must also factor in patient preferences, clinician expertise, and resource availability. Such considerations are crucial given the exponential expansion of new surgical techniques and pharmacologic options in the last decade. Although literature exists for decision-making on various obesity management topics, there are no scoping reviews systematically mapping the literature. This scoping review is timely given that the treatment of obesity has evolved into a multidisciplinary endeavor with myriad management decisions that both patients and clinicians must navigate. INCLUSION CRITERIA The review will consider for inclusion full-text primary studies, published in English from the year 2000 onwards, pertaining to decision-making in obesity management for health care providers involved in obesity management for patients aged ≥18 years. METHODS This scoping review will be conducted in accordance with the JBI methodology for scoping reviews. Embase (Elsevier), MEDLINE (PubMed), Scopus (Elsevier), Web of Science (Clarivate), CINAHL Complete (EBSCO), PsycINFO (EBSCO), and Cochrane Central (Wiley) will be systematically searched using a predefined strategy. Two independent reviewers will conduct a 3-tiered screen of identified articles, with a third reviewer resolving disputes. Data extraction will be performed using a predefined, yet flexible form. Descriptive summaries and mapping will be provided for included studies. Available evidence and knowledge gaps will be identified and summarized as they relate to specific concepts, populations, and contexts in obesity management decision-making.

Abstract
INTRODUCTION The psychological profile of obese people deciding to start obesity treatment may be different from those not choosing to seek the therapy. Previous studies have shown a higher incidence of depression in obese than in normal weight people. However, data are lacking concerning the occurrence of depressive symptoms and their severity in obese subjects who do or do not decide to start treatment for obesity. Therefore, the aim of this study was to evaluate the prevalence and severity of depressive symptoms among obese people starting treatment and not seeking treatment for obesity. MATERIALS AND METHODS Enrolled subjects were 331 adults (241 women, 90 men), including 193 obese subjects starting treatment for obesity (46.8 ± 13.2 years, BMI 37.6 ± 5.5 kg/m2) and 138 obese volunteers never seeking treatment for obesity (44.3 ± 12.5 years, BMI 34.7 ± 4.3 kg/m2). Depression levels were determined using the Beck Depression Inventory (BDI). RESULTS The level of depression was significantly higher among those starting treatment for obesity than those never seeking treatment for obesity (13.2 ± 9.2 vs. 9.5 ± 7.9 points; p < 0.001). This difference was statistically significant in women (14.4 ± 9.2 and 11.0 ± 8.2 points, respectively; p < 0.01), but not in men (7.2 ± 6.4 and 7.3 ± 7.1 points, respectively; p = 0.95). There were more women with moderate/severe depressive symptoms in the group starting treatment than in the group not seeking treatment for obesity (44.7 and 24.4%, respectively). No such difference was observed in men. CONCLUSIONS Obese subjects, especially women, with depressive symptoms are more likely to start treatment for obesity. LEVEL OF EVIDENCE Level III, case-control analytic study.

Abstract
BACKGROUND A substantial proportion of severely obese patients undergoing bariatric surgery have not developed disease as a consequence of obesity. Little is known about the effects of bariatric surgery on health-related quality of life (HRQL) in this patient group. In a prospective study at a public hospital, we compared HRQL in gastric bypass patients with and without obesity-related disease before and 2 years after surgery. METHODS HRQL was assessed in 232 severely obese patients before, 1 year, and 2 years after Roux-en-Y gastric bypass. We used a general HRQL questionnaire, the Short Form 36, and an obesity-specific questionnaire, the Obesity-related Problems scale. The patients were divided into two groups based on the presence of obesity-related disease (n = 146) or not (n = 86) before surgery. We defined obesity-related disease as having at least one of the following conditions: type 2 diabetes mellitus, hypertension, dyslipidemia, coronary heart disease, obstructive sleep apnea, gastroesophageal reflux disease, or osteoarthritis. Linear mixed models were used to analyze the HRQL outcomes. RESULTS Before surgery, patients with no obesity-related disease reported equal HRQL compared with patients with obesity-related disease. Two years after gastric bypass, substantial improvements in all subscales of Short Form 36 and in Obesity-related Problems scale were observed in both groups, and the improvements were similar in 7 out of 8 subscales of Short Form 36 as well as for the Obesity-related Problems scale. CONCLUSIONS Baseline HRQL was similar in patients with and without obesity-related disease prior to gastric bypass. After surgery, patients with no comorbidity had similar positive changes in HRQL as patients with one or several comorbidities. These findings indicate that other factors than obesity-related disease are at least as important for severely obese patients' impaired HRQL.

Abstract
Physical activity is considered fundamental in lifestyle interventions. We explore experiences of physical activity prior to, during, and following a 10- to 14-week inpatient lifestyle modification program, including high volume of physical activity, for the treatment of severe obesity. Eight participants from a prospective clinical trial were selected to participate in a complementary qualitative study. The participants' experiences with physical activity during and following the treatment program represented different opposites: "pain and pleasure," "desire and duty," and "bubble and battle." We summarized the findings into one overall theme: "the ambivalence of attending physical activity." The ambivalence is experienced as a shift in how participants experience physical activity during the intervention period and as an ongoing, dynamic, and constantly shifting experience during such activity. To address and reflect upon such experiences with the participants, and acknowledge ambivalence as a legitimate part of being physically active, might be important within obesity treatment.

Effects of lifestyle interventions that include a physical activity component in class II and III obese individuals: a systematic review and meta-analysis. PLoS One 2015; 10:e0119017. [PMID: 25830342 PMCID: PMC4382170 DOI: 10.1371/journal.pone.0119017] [Citation(s) in RCA: 82] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2014] [Accepted: 01/08/2015] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND In class II and III obese individuals, lifestyle intervention is the first step to achieve weight loss and treat obesity-related comorbidities before considering bariatric surgery. A systematic review, meta-analysis, and meta-regression were performed to assess the impact of lifestyle interventions incorporating a physical activity (PA) component on health outcomes of class II and III obese individuals. METHODS An electronic search was conducted in 4 databases (Medline, Scopus, CINAHL and Sportdiscus). Two independent investigators selected original studies assessing the impact of lifestyle interventions with PA components on anthropometric parameters, cardiometabolic risk factors (fat mass, blood pressure, lipid and glucose metabolism), behaviour modification (PA and nutritional changes), and quality of life in adults with body mass index (BMI) ≥ 35 kg/m2. Estimates were pooled using a random-effect model (DerSimonian and Laird method). Heterogeneity between studies was assessed by the Cochran's chi-square test and quantified through an estimation of the I². RESULTS Of the 3,170 identified articles, 56 met our eligibility criteria, with a large majority of uncontrolled studies (80%). The meta-analysis based on uncontrolled studies showed significant heterogeneity among all included studies. The pooled mean difference in weight loss was 8.9 kg (95% CI, 10.2-7.7; p < 0.01) and 2.8 kg/m² in BMI loss (95% CI, 3.4-2.2; p < 0.01). Long-term interventions produced superior weight loss (11.3 kg) compared to short-term (7.2 kg) and intermediate-term (8.0 kg) interventions. A significant global effect of lifestyle intervention on fat mass, waist circumference, blood pressure, total cholesterol, LDL-C, triglycerides and fasting insulin was found (p<0.01), without significant effect on HDL-C and fasting blood glucose. CONCLUSIONS Lifestyle interventions incorporating a PA component can improve weight and various cardiometabolic risk factors in class II and III obese individuals. However, further high quality trials are needed to confirm this evidence, especially beyond weight loss.

Am J Med 2013; 126:236-42, 242.e1-2. [PMID: 23410564 PMCID: PMC3574274 DOI: 10.1016/j.amjmed.2012.10.010] [Citation(s) in RCA: 73] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2012] [Revised: 08/22/2012] [Accepted: 10/01/2012] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Severe obesity (body mass index [BMI] ≥40 kg/m(2)) is a serious public health concern. Although bariatric surgery is an efficacious treatment approach, it is limited in reach; thus, nonsurgical treatment alternatives are needed. We examined the 4-year effects of an intensive lifestyle intervention on body weight and cardiovascular disease risk factors among severely obese, compared with overweight (25 ≤BMI <30), class I (30 ≤BMI <35), and class II obese (35 ≤BMI <40) participants. METHODS There were 5145 individuals with type 2 diabetes (45-76 years, BMI ≥25 kg/m(2)) randomized to an intensive lifestyle intervention or diabetes support and education. The lifestyle intervention group received a behavioral weight loss program that included group and individual meetings, a ≥10% weight loss goal, calorie restriction, and increased physical activity. Diabetes support and education received a less intense educational intervention. Four-year changes in body weight and cardiovascular disease risk factors were assessed. RESULTS Across BMI categories, 4-year changes in body weight were significantly greater in lifestyle participants compared with diabetes support and education (Ps <.05). At year 4, severely obese lifestyle participants lost 4.9%±8.5%, which was similar to class I (4.8%±7.2%) and class II obese participants (4.4%±7.6%), and significantly greater than overweight participants (3.4%±7.0%; P <.05). Four-year changes in low-density-lipoprotein cholesterol, triglycerides, diastolic blood pressure, HbA(1c), and blood glucose were similar across BMI categories in lifestyle participants; however, the severely obese had less favorable improvements in high-density-lipoprotein cholesterol (3.1±0.4 mg/dL) and systolic blood pressure (-1.4±0.7 mm Hg) compared with the less obese (Ps <.05). CONCLUSION Lifestyle interventions can result in important long-term weight losses and improvements in cardiovascular disease risk factors among a significant proportion of severely obese individuals.

Abstract
OBJECTIVE To determine if length of first stay impacts on weight loss and cardiovascular fitness, at 1 and 2 years in severely obese patients enrolled in intermittent residential programs. METHODS In a retrospective follow-up study, we assessed weight loss and changes in cardiovascular fitness (VO₂ peak) at 1 and 2 years in 179 severely obese adults who participated in two intermittent residential programmes. Both programmes consisted of five stays at the Røros Rehabilitation Centre over a 2-year period, but programme A consisted of a much longer first stay compared with programme B (8 vs. 2 weeks). RESULTS Of 179 participants (BMI 44 ± 6 kg/m²), 162 completed 1-year and 117 2-year evaluation. Programme A led to significantly larger weight reduction (-20.7 ± 10.8 vs. -13.5 ± 8.1 kg and -16.0 ± 12.7 vs. -7.9 ± 11.2 kg, p < 0.0001) and improvement in VO₂ peak (7.8 vs. 3.6 ml/kg/min (p < 0.0001) and 5.6 vs. 2.5 ml/kg/min (p < 0.01)) at both 1 and 2 years, compared with programme B. Intention-to-treat analysis showed similar results. CONCLUSION A residential intermittent programme with a longer initial stay is associated with better weight loss and improvement in cardiovascular fitness at both 1 and 2 years. A longer follow-up is needed to clearly establish the sustainability of these programmes.

Abstract
Obesity (or being overweight) is now considered a by-product of membership of developed societies. Moreover, it is considered a growing ‘global’ health problem. This article reports on a small qualitative study of adults who fell into one or other of these categories in Norway in 2010, and who have been faced with decisions about lifestyle versus surgical remedies. This decision making is contextualized and the principal criteria examined. Embodiment, bodywork, self- and social identity, stigma, deviance and issues around the idea of personal responsibility and public health emerge as key themes. The concluding paragraphs commend incorporation of a macro- or social structural perspective to the conceptualization and investigation of obesity.

Abstract
BACKGROUND Bariatric surgery patients are required to receive psychological clearance before they are eligible for surgery. In spite of this, there are no standard assessment practices or tests designed specifically for these evaluations. OBJECTIVE The objective of this study is to determine the reliability and construct validity of the PsyBari, a psychological test designed for bariatric surgery patients. METHODS The PsyBari was administered to 752 patients. Internal consistency reliability and exploratory factor analyses were conducted. RESULTS Items with high percentages of missing data, low communalities, and low item loadings were identified and deleted. Cronbach's α = 0.930 (0.940 for males and 0.927 for females). Six factors were obtained for each gender: for females, awareness of eating habits, early life problems due to weight, dysphoric feelings about weight, weight-related impairment, surgical anxiety, and guilty feelings related to eating; for males, physical impairment with depression, awareness of eating habits, early life problems due to weight, interpersonal support with anxiety about weight, anger, and guilty feelings about eating habits. CONCLUSIONS Results indicate that there are unique psychometric parameters when constructing tests for bariatric surgery patients. The PsyBari has good overall reliability, although two of the 11 subscales have poor reliability. Factor analyses revealed six factors for each gender. Some factors were common for both genders, some were unique for each gender, and some consisted of mixed constructs.

Abstract
BACKGROUND Few studies have looked at non-surgical alternatives for morbid obese patients. This study aims to compare 1-year weight loss and changes in risk factors and comorbidities after bariatric surgery and three conservative treatments. METHODS Patients with morbid obesity (BMI > 40 or BMI > 35 kg/m(2) plus comorbidities) on waiting list for bariatric surgery, were non-randomly allocated to (A) bariatric surgery or to one of three conservative treatments; (B) residential intermittent program; (C) commercial weight loss camp and (D) hospital outpatient program. Body weight, risk factors and comorbidities were assessed at baseline and 1 year. RESULTS Of 206 participants, 179 completed the study. All treatments resulted in significant weight loss, but bariatric surgery (40 ± 14 kg, 31 ± 9%) led to the largest weight loss (P < 0.0001). There were no differences in weight loss between B and C (22 ± 13 kg, 15 ± 8% vs. 18 ± 12 kg, 13 ± 8%), but these resulted in larger weight loss compared with D (7 ± 10 kg, 5 ± 8%). There were no differences in changes in total or LDL cholesterol, triacylglycerols or glucose between groups; however, the increase in HDL cholesterol was significantly larger in groups A and C. There were no differences in comorbidities resolution between groups A and B, C and D combined (except hypertension, which was better in group A). CONCLUSION In conclusion, although bariatric surgery leads to a greater weight loss at 1 year compared with conservative treatment, in patients with morbid obesity, clinical significant weight loss and similar improvements in risk factors and comorbidities resolution can also be achieved with lifestyle interventions.

Abstract
OBJECTIVE Rates of severe obesity (BMI ≥40 kg/m(2)) are on the rise, and effective treatment options are needed. We examined the effect of an intensive lifestyle intervention (ILI) on weight loss, cardiovascular disease (CVD) risk, and program adherence in participants with type 2 diabetes who were severely obese compared with overweight (BMI 25 to <30 kg/m(2)), class I (BMI 30 to <35 kg/m(2)), and class II (BMI 35 to <40 kg/m(2)) obese participants. RESEARCH DESIGN AND METHODS Participants in the Action for Health in Diabetes (Look AHEAD) trial were randomly assigned to ILI or diabetes support and education (DSE). DSE participants received a less intense educational intervention, whereas ILI participants received an intensive behavioral treatment to increase physical activity (PA) and reduce caloric intake. This article focuses on the 2,503 ILI participants (age 58.6 ± 6.8 years). RESULTS At 1 year, severely obese participants in the ILI group lost -9.04 ± 7.6% of initial body weight, which was significantly greater (P < 0.05) than ILI participants who were overweight (-7.43 ± 5.6%) and comparable to class I (-8.72 ± 6.4%) and class II obese (-8.64 ± 7.4%) participants. All BMI groups had comparable improvements in fitness, PA, LDL cholesterol, triglycerides, blood pressure, fasting glucose, and HbA(1c) at 1 year. ILI treatment session attendance was excellent and did not differ among weight categories (severe obese 80% vs. others 83%; P = 0.43). CONCLUSIONS Severely obese participants in the ILI group had similar adherence, percentage of weight loss, and improvement in CVD risk compared with less obese participants. Behavioral weight loss programs should be considered an effective option for this population.
