Patient perceptions about obesity management in the context of concomitant care for other chronic diseases.

Background: Approximately 15% of Canadian adults live with two or more chronic diseases, many of which are obesity related. The degree to which Canadian obesity treatment guidelines are integrated into chronic disease management is unknown. Methods: We conducted a 12-min online survey among a non-probability sample of 2506 adult Canadians who met at least one of the following criteria: 1) BMI ≥30 kg/m2; 2) medical diagnosis of obesity; 3) undergone medically supervised treatment for obesity; or 4) a belief that excess/abnormal adipose tissue impairs their health. Participants must have been diagnosed with at least one of 12 prevalent obesity-related chronic diseases. Data analysis consisted of descriptive statistics. Results: One in four (26.4%) reported a diagnosis of obesity, but only 9.2% said they had received medically supervised obesity treatment. The majority (55%) agreed obesity makes managing their other chronic diseases challenging; 39% agreed their chronic disease(s) have progressed or gotten worse because of their obesity. While over half (54%) reported being aware that obesity is classified as a chronic disease, 78% responded obesity was their responsibility to manage on their own. Only 33% of respondents responded they have had success with obesity treatment. Interpretation: While awareness of obesity as a chronic disease is increasing, obesity care within the context of a wider chronic disease management model is suboptimal. More work remains to be done to make Canadian obesity guidelines standard for obesity care.

Weight bias internalization and beliefs about the causes of obesity among the Canadian public.

BACKGROUND: Explicit weight bias is known as negative attitudes and beliefs toward individuals due to their weight status and can be perpetuated through misconceptions about the causes of obesity. Individuals may also experience weight bias internalization (WBI) when they internalize negative weight-related attitudes and self-stigmatize. There is a paucity of research on the beliefs about the causes of obesity and the prevalence of WBI among public Canadian samples. The aim of this study was to describe these attitudes and beliefs about obesity among a large Canadian sample across the weight spectrum. METHODS: A Canadian sample of adults (N = 942; 51% Women; mean age group = 45-54 years; mean body mass index [BMI] = 27.3 ± 6.7 kg/m2) completed an online questionnaire. Participants completed the Modified Weight Bias Internalization Scale, the Anti-Fat Attitudes Questionnaire, and the Causes of Obesity Questionnaire. RESULTS: Mean WBI score within the entire sample was 3.38 ​​ ± 1.58, and females had higher mean scores as compared to males (p < 0.001). Mean scores were also higher among individuals with a BMI of > 30 kg/m2 (4.16 ± 1.52), as compared to individuals with a BMI of 25-30 kg/m2 (3.40 ± 1.50), and those with a BMI of 20-25 kg/m2 or below 18.5 kg/m2 (2.81 ± 1.44) (p < 0.001 for all). Forty four percent of Canadians believed behavioural causes are very or extremely important in causing obesity, 38% for environmental causes, 28% for physiological and 27% for psychosocial causes. Stronger beliefs in behavioural causes were associated with higher levels of explicit weight bias. No BMI differences were reported on the four different subscales of the Causes of Obesity Questionnaire. CONCLUSIONS: Weight bias internalization is prevalent among Canadians across all body weight statuses, and the public endorses behavioural causes of obesity, namely physical inactivity and overeating, more than its other causes. Findings warrant the reinforcement of efforts aimed at mitigating weight bias by educating the public about the complexity of obesity and by highlighting weight bias as a systemic issue that affects all Canadians living in diverse body weight statuses.

European Association for the Study of Obesity Position Statement on Medical Nutrition Therapy for the Management of Overweight and Obesity in Adults Developed in Collaboration with the European Federation of the Associations of Dietitians.

INTRODUCTION: Obesity affects nearly 1 in 4 European adults increasing their risk for mortality and physical and psychological morbidity. Obesity is a chronic relapsing disease characterized by abnormal or excessive adiposity with risks to health. Medical nutrition therapy based on the latest scientific evidence should be offered to all Europeans living with obesity as part of obesity treatment interventions. METHODS: A systematic review was conducted to identify the latest evidence published in the November 2018-March 2021 period and to synthesize them in the European guidelines for medical nutrition therapy in adult obesity. RESULTS: Medical nutrition therapy should be administered by trained dietitians as part of a multidisciplinary team and should aim to achieve positive health outcomes, not solely weight changes. A diverse range of nutrition interventions are shown to be effective in the treatment of obesity and its comorbidities, and dietitians should consider all options and deliver personalized interventions. Although caloric restriction-based interventions are effective in promoting weight reduction, long-term adherence to behavioural changes may be better supported via alternative interventions based on eating patterns, food quality, and mindfulness. The Mediterranean diet, vegetarian diets, the Dietary Approaches to Stop Hypertension, portfolio diet, Nordic, and low-carbohydrate diets have all been associated with improvement in metabolic health with or without changes in body weight. In the November 2018-March 2021 period, the latest evidence published focused around intermittent fasting and meal replacements as obesity treatment options. Although the role of meal replacements is further strengthened by the new evidence, for intermittent fasting no evidence of significant advantage over and above continuous energy restriction was found. Pulses, fruit and vegetables, nuts, whole grains, and dairy foods are also important elements in the medical nutrition therapy of adult obesity. DISCUSSION: Any nutrition intervention should be based on a detailed nutritional assessment including an assessment of personal values, preferences, and social determinants of eating habits. Dietitians are expected to design interventions that are flexible and person centred. Approaches that avoid caloric restriction or detailed eating plans (non-dieting approaches) are also recommended for improvement of quality of life and body image perceptions.

Obesidad en adultos: guía de práctica clínica adaptada para Chile / Obesity in adults: clinical practice guideline adapted for Chile

La Sociedad Chilena de Cirugía Bariátrica y Metabólica, junto a otras sociedades científicas, lideró el proceso de adaptación de la guía de práctica clínica de obesidad en adultos para Chile, tomando como base las directrices desarrolladas para Canadá. La guía canadiense buscó, entre sus principales objetivos, proponer cambios en el enfoque del manejo de la obesidad como una enfermedad crónica y para mejorar los desenlaces de salud centrados en los pacientes, en lugar de enfocarse en la pérdida de peso como principal y único objetivo. Se convocó a un grupo de 58 profesionales para el desarrollo del proyecto, quienes revisaron y utilizaron el método para el análisis de las recomendaciones originales y desarrollo de recomendaciones . Para la elaboración de nuevas recomendaciones, se llevó a cabo una búsqueda de revisiones sistemáticas en la base de datos Epistemonikos, y se utilizó metodología GRADE y el marco para la evaluación de la evidencia y la descripción de la recomendación. Se adoptaron 76 de las 80 recomendaciones de la guía canadiense, se adaptó una recomendación y se desarrollaron 12 preguntas nuevas con sus respectivas recomendaciones. El proceso de adaptación permitió acortar el tiempo necesario para elaborar una guía de práctica clínica en obesidad del adulto para nuestro país. El cambio en el enfoque hacia una aproximación sin estigma y centrada en la salud y no en el peso, es universal y posible de aplicar en diferentes países y contextos.

Exploring weight bias internalization in pregnancy.

BACKGROUND: Recent research has shown that pregnant individuals experience weight stigma throughout gestation, including negative comments and judgement associated with gestational weight gain (GWG). Weight bias internalization (WBI) is often a result of exposure to weight stigma and is detrimental to biopsychological health outcomes. The purpose of this study was to explore WBI in pregnancy and compare scores based on maternal weight-related factors including pre-pregnancy body mass index (BMI), obesity diagnosis and excessive GWG. METHODS: Pregnant individuals in Canada and USA completed a modified version of the Adult Weight Bias Internalization Scale. Self-reported pre-pregnancy height and weight were collected to calculate and classify pre-pregnancy BMI. Current weight was also reported to calculate GWG, which was then classified as excessive or not based on Institute of Medicine (2009) guidelines. Participants indicated if they were diagnosed with obesity by a healthcare provider. Inferential analyses were performed comparing WBI scores according to pre-pregnancy BMI, excessive GWG, and obesity diagnosis. Significance was accepted as p < 0.05 and effect sizes accompanied all analyses. RESULT: 336 pregnant individuals completed the survey, with an average WBI score of 3.9 ± 1.2. WBI was higher among those who had a pre-pregnancy BMI of obese than normal weight (p = 0.04, η2 = 0.03), diagnosed with obesity than not diagnosed (p < 0.001, Cohen's d = 1.3), and gained excessively versus not (p < 0.001, Cohen's d = 1.2). CONCLUSIONS: Pregnant individuals who have a higher BMI, obesity and gain excessively may experience WBI. Given that weight stigma frequently occurs in pregnancy, effective person-oriented strategies are needed to mitigate stigma and prevent and care for WBI.

Outcomes of the first global multidisciplinary consensus meeting including persons living with obesity to standardize patient-reported outcome measurement in obesity treatment research.

Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the key PROs and preferred PROMs for obesity treatment research. It comprised of 35 people living with obesity (PLWO) and healthcare providers (HCPs). Formal presentations, nominal group techniques, and modified Delphi exercises were used to develop consensus-based recommendations. The following eight PROs were considered important: self-esteem, physical health/functioning, mental/psychological health, social health, eating, stigma, body image, and excess skin. Self-esteem was considered the most important PRO, particularly for PLWO, while physical health was perceived to be the most important among HCPs. For each PRO, one or more PROMs were selected, except for stigma. This consensus meeting was a first step toward standardizing PROs (what to measure) and PROMs (how to measure) in obesity treatment research. It provides an overview of the key PROs and a first selection of the PROMs that can be used to evaluate these PROs.

Updating the Canadian clinical practice guideline for managing pediatric obesity: a protocol.

BACKGROUND: Since the first national guideline for managing obesity in adults and children in Canada was published in 2007, new evidence has emerged and guideline standards have evolved. Our purpose is to describe the protocol used to update the Canadian clinical practice guideline for managing pediatric obesity. METHODS: This guideline will update the pediatric components of the 2007 Canadian clinical practice guideline for the management of obesity. In partnership with Obesity Canada, we began preliminary work in 2019; activities are scheduled for completion in 2022. The guideline will follow standards developed by the National Academy of Medicine and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) working group. Guideline development will be informed by 5 complementary literature reviews: a scoping review that focuses on clinical assessment in pediatric obesity management and 4 systematic reviews to synthesize evidence regarding families' values and preferences as well as the safety and effectiveness of interventions (psychological and behavioural; pharmacotherapeutic; and surgical). We will use standard systematic review methodology, including summarizing and assessing the certainty of evidence and determining the strength of recommendations. Competing interests will be managed proactively according to recommendations from the Guidelines International Network. Diverse stakeholders, including families and clinicians, will be engaged throughout guideline development. INTERPRETATION: The guideline will support Canadian families and clinicians to make informed, value-sensitive and evidence-based clinical decisions related to managing pediatric obesity. The guideline and accompanying resources for end-users will be published in English and French, and we will partner with Obesity Canada to optimize dissemination using integrated and end-of-project knowledge translation.

Mapping changes in the obesity stigma discourse through Obesity Canada: a content analysis.

BACKGROUND: Stigmatization of persons living with obesity is an important public health issue. In 2015, Obesity Canada adopted person-first language in all internal documentation produced by the organization, and, from 2017, required all authors to use person-first language in abstract submissions to Obesity Canada hosted conferences. The impact of this intentional shift in strategic focus is not known. Therefore, the aim of this study was to conduct a content analysis of proceedings at conferences hosted by Obesity Canada to identify whether or how constructs related to weight bias and obesity stigma have changed over time. METHODS: Of 1790 abstracts accepted to conferences between 2008-2019, we excluded 353 abstracts that featured animal or cellular models, leaving 1437 abstracts that were reviewed for the presence of five constructs of interest and if they changed over time: 1) use of person-first versus use of disease-first terminology, 2) incorporation of lived experience of obesity, 3) weight bias and stigma, 4) aggressive or alarmist framing and 5) obesity framed as a modifiable risk factor versus as a disease. We calculated and analyzed through linear regression: 1) the overall frequency of use of each construct over time as a proportion of the total number of abstracts reviewed, and 2) the ratio of abstracts where the construct appeared at least once based on the total number of abstracts. RESULTS: We found a significant positive correlation between use of person-first language in abstracts and time (R2 = 0.51, p < 0.01 for frequency, R2 = 0.65, p < 0.05 for ratio) and a corresponding negative correlation for the use of disease-first terminology (R2 = 0.48, p = 0.01 for frequency, R2 = 0.75, p < 0.001 for ratio). There was a significant positive correlation between mentions of weight bias and time (R2 = 0.53 and 0.57, p < 0.01 for frequency and ratio respectively). CONCLUSION: Use of person-first language and attention to weight bias increased, while disease-first terminology decreased in accepted abstracts over the past 11 years since Obesity Canada began hosting conferences and particularly since more explicit actions for expectations to use person-first language were put in place in 2015 and 2017.

Complexity and Stigma of Pediatric Obesity.

Weight stigma is rooted in a fundamental misunderstanding of the origins of obesity, wherein the interplay of behavioral, environmental, genetic, and metabolic factors is deemphasized. Instead, the widespread societal and cultural presence of weight stigma fosters misconceptions of obesity being solely a result of unhealthy personal choices. Weight stigma is pervasive in childhood and adolescence and can affect individuals throughout their life. Although the prevalence of pediatric obesity remains high throughout the world, it becomes increasingly important to understand how weight stigma affects weight and health outcomes in children and adolescents with overweight or obesity, including in those with rare genetic diseases of obesity. We identified and reviewed recent literature (primarily published since 2000) on weight stigma in the pediatric setting. Articles were identified with search terms including pediatric obesity, weight bias, weight stigma, weight-based teasing and bullying, and weight bias in health care. In this narrative review, we discuss the stigma of pediatric obesity as it relates to the complex etiology of obesity as well as describe best practices for avoiding bias and perpetuating stigma in the health care setting.

Reducing weight bias in obesity management, practice and policy

Policy makers developing obesity policies should assess and reflect on their own attitudes and beliefs related to obesity. Public health policy makers should avoid using stigmatizing language and images. It is well established that shaming does not change behaviours. In fact, shaming can increase the likelihood of individuals pursuing unhealthy behaviours and has no place in an evidence-based approach to obesity management. Avoid making assumptions in population health policies that healthy behaviours will or should result in weight change. Weight is not a behaviour and should not be a target for behaviour change. Avoid evaluating healthy eating and physical activity policies, programs and campaigns in terms of population level weight or BMI outcomes. Instead, emphasize health and quality of life for people of all sizes. Because weight bias contributes to health and social inequalities, advocate for and support people living with obesity. This includes supporting policy action to prevent weight bias and weight-based discrimination. Policy makers should know that most people living with obesity have experienced weight bias or some form of weight-based discrimination. Public health policy makers should consider weight bias and obesity stigma as added burdens on population health outcomes and develop interventions to address them. To avoid compounding the problem, we encourage policy makers to do no harm, and to develop people-centered policies that move beyond personal responsibility, recognize the complexity of obesity, and promote health, dignity and respect, regardless of body weight or shape. Health care providers should ensure their clinical environment is accessible, safe and respectful to all patients regardless of their weight or size. Make efforts to improve health and quality of life rather than solely focusing on obesity management. Ask permission before weighing someone, and never weigh people in front of others; instead, place weighing scales in private areas. Health care providers should consider how their office's physical space accommodates people of all sizes and ensure they have properly sized equipment (e.g., blood pressure cuffs, gowns, chairs, beds) ready in clinical rooms prior to patients arriving. Because weight bias impacts morbidity and mortality, advocate for and support people living with obesity. This includes action to create supportive healthcare environments and policies for people of all sizes.

A critical analysis of obesity prevention policies and strategies.

OBJECTIVES: Public health policies have been criticized for promoting a simplistic narrative that may contribute to weight bias. Weight bias can impact population health by increasing morbidity and mortality. The objectives of this study were to: 1 ) critically analyze Canadian obesity prevention policies and strategies to identify underlying dominant narratives; 2) deconstruct dominant narratives and consider the unintended consequences for people with obesity; and 3) make recommendations to change dominant obesity narratives that may be contributing to weight bias. METHODS: We applied Bacchi's "what's-the-problem-represented-to-be?" (WPR) approach to 15 obesity prevention policies and strategies (1 national, 2 territorial and 12 provincial). Bacchi's WPR approach is composed of six analytical questions designed to identify conceptual assumptions as well as possible effects of policies. RESULTS: We identified five prevailing narratives that may have implications for public health approaches and unintended consequences for people with obesity: 1 ) childhood obesity threatens the health of future generations and must be prevented; 2) obesity can be prevented through healthy eating and physical activity; 3) obesity is an individual behaviour problem; 4) achieving a healthy body weight should be a population health target; and 5) obesity is a risk factor for other chronic diseases, not a disease in itself. CONCLUSION: The consistent way in which obesity is constructed in Canadian policies and strategies may be contributing to weight bias in our society. We provide some recommendations for changing these narratives to prevent further weight bias and obesity stigma.

Potential Policies and Laws to Prohibit Weight Discrimination: Public Views from 4 Countries.

CONTEXT: People viewed as "overweight" or "obese" are vulnerable to weight-based discrimination, creating inequities and adverse health outcomes. Given the high rates of obesity recorded globally, studies documenting weight discrimination in multiple countries, and an absence of legislation to address this form of discrimination, research examining policy remedies across different countries is needed. Our study provides the first multinational examination of public support for policies and legislation to prohibit weight discrimination. METHODS: Identical online surveys were completed by 2,866 adults in the United States, Canada, Australia, and Iceland. We assessed public support for potential laws to prohibit weight-based discrimination, such as adding body weight to existing civil rights statutes, extending disability protections to persons with obesity, and instituting legal measures to prohibit employers from discriminating against employees because of body weight. We examined sociodemographic and weight-related characteristics predicting support for antidiscrimination policies, and the differences in these patterns across countries. FINDINGS: The majority of participants in the United States, Canada, and Australia agreed that their government should have specific laws in place to prohibit weight discrimination. At least two-thirds of the participants in all 4 countries expressed support for policies that would make it illegal for employers to refuse to hire, assign lower wages, deny promotions, or terminate qualified employees because of body weight. Women and participants with higher body weight expressed more support for antidiscrimination measures. Beliefs about the causes of obesity were also related to support for these laws. CONCLUSIONS: Public support for legal measures to prohibit weight discrimination can be found in the United States, Canada, Australia, and Iceland, especially for laws to remedy this discrimination in employment. Our findings provide important information for policymakers and interest groups both nationally and internationally and can help guide discussions about policy priorities to reduce inequities resulting from weight discrimination.

Inequities in healthcare: a review of bias and discrimination in obesity treatment.

This review is based on an exploration of the published literature over the past 20 years in the area of weight bias, stigma and discrimination and its association with obesity treatment. National and international obesity organizations have identified obesity stigma as a key barrier to effectively addressing the obesity epidemic and have called for theory driven interventions to reduce it. Both the Canadian Obesity Network (http://www.obesitynetwork.ca) and the Obesity Society (http://www.obesity.org) have strategic directions, mission statements and collaborations that strongly oppose weight bias and recognize the potential of such bias to negatively impact obesity treatment. Comprehensive reviews of the literature in the area of weight bias have been published and have subsequently raised awareness of the potential impact of weight bias and discrimination on the health and well-being of individuals living with obesity. The purpose of this review is to highlight drivers of weight bias and to discuss its impact on obesity treatment.
