Experiences and perceptions of dietitians for obesity management: a general practice qualitative study.

BACKGROUND: Multi-component lifestyle interventions are the first line treatment for obesity. Dietitians are ideally placed healthcare professionals to deliver such interventions. However, only a small proportion of patients with obesity are referred by general practice to dietitians, and the reasons for this are not clear. The present study aimed to explore general practice healthcare professionals' (GPHCPs) experiences and perceptions of dietitians in the context of obesity management. METHODS: A convenience sample of GPHCPs practicing in the UK was recruited via a targeted social media strategy, using virtual snowball sampling. Data were collected using semi-structured interviews and analysed using framework analysis. RESULTS: In total, 20 participants were interviewed (11 general practice nurses and nine general practitioners). Experiences of referring patients with obesity for dietetic intervention resulted in two main themes: (i) access barriers and (ii) the dietetic consult experience. Three themes emerged from participants' perceptions of a role for general practice dietitians: (i) utilising dietetic expertise; (ii) access to dietitian; and (iii) time. Participants experienced barriers to accessing dietitians for obesity management and felt that having a dietitian working within their general practice team would help address this. Having a dietitian embedded within their general practice team was perceived to have the potential to alleviate GPHCPs' clinical time pressures, offer opportunities for upskilling, and may improve patient engagement with obesity management. CONCLUSIONS: GPHCPs perceived that embedding a dietitian within their general practice team would be valuable and beneficial for obesity management. Our findings provide support for the funding of general practice dietitian roles in the UK.

Perceptions, Attitudes, and Barriers to Obesity Care in Mexico: Data From the ACTION-IO Study.

OBJECTIVE: The Awareness, Care, and Treatment in Obesity Management-International Observation (ACTION-IO) study (ClinicalTrials.gov identifier NCT03584191) aimed to identify perceptions, attitudes, behaviors, and barriers to effective obesity care in people with obesity (PwO) and health care professionals (HCPs). This study presents the results from Mexico. METHODS: An online survey was conducted. In Mexico, eligible PwO were ≥18 years of age with BMI ≥30 kg/m2 based on self-reported height and weight. Eligible HCPs had direct patient care. RESULTS: The survey was completed by 2,000 PwO and 400 HCPs in Mexico. Many PwO (71%) and HCPs (94%) categorized obesity as a chronic disease. Sixty-three percent of PwO felt motivated to lose weight, but many HCPs perceived that PwO were not interested in losing weight (76%) or motivated to lose weight (69%). Lack of financial means to support weight-loss efforts was a barrier for PwO (34%) to discussing weight with HCPs. Sixty-five percent of PwO had discussed weight with HCPs in the past 5 years. PwO (80%) and HCPs (89%) considered lack of exercise as the main barrier to weight loss. Few PwO (34%) had successfully lost ≥5% of their body mass over the past 3 years. CONCLUSIONS: This ACTION-IO study in Mexico identified discrepancies in the perceptions of PwO and HCPs, highlighting opportunities for further education and patient-centered approaches.

Difference in Insulin Resistance Assessment between European Union and Non-European Union Obesity Treatment Centers (ESPE Obesity Working Group Insulin Resistance Project).

INTRODUCTION: The obesity epidemic has become one of the most important public health issues of modern times. Impaired insulin sensitivity seems to be the cornerstone of multiple obesity related comorbidities. However, there is no accepted definition of impaired insulin sensitivity. OBJECTIVE: We hypothesize that assessment of insulin resistance differs between centers. METHODS: The ESPE Obesity Working Group (ESPE ObWG) Scientific Committee developed a questionnaire with a focus on the routine practices of assessment of hyperinsulinemia and insulin resistance, which was distributed through Google Docs platform to the clinicians and researchers from the current ESPE ObWG database (n = 73). Sixty-one complete responses (84% response rate) from clinicians and researchers were analyzed: 32 from European Union (EU) centers (representatives of 14 countries) and 29 from Non-EU centers (representatives from 10 countries). Standard statistics were used for the data analysis. RESULTS: The majority of respondents considered insulin resistance (IR) as a clinical tool (85.2%) rather than a research instrument. For the purpose of IR assessment EU specialists prefer analysis of the oral glucose tolerance test (OGTT) results, whereas non-EU ones mainly use Homeostatic Model Assessment of Insulin Resistance (HOMA-IR; p = 0.032). There was no exact cutoff for the HOMA-IR in either EU or non-EU centers. A variety of OGTT time points and substances measured per local protocol were reported. Clinicians normally analyzed blood glucose (88.52% of centers) and insulin (67.21%, mainly in EU centers, p = 0.0051). Furthermore, most participants (70.5%) considered OGTT insulin levels as a more sensitive parameter of IR than glucose. Meanwhile, approximately two-thirds (63.9%) of the centers did not use any cutoffs for the insulin response to the glucose load. CONCLUSIONS: Since there is no standard for the IR evaluation and uniform accepted indication of performing, an OGTT the assessment of insulin sensitivity varies between EU and non-EU centers. A widely accepted standardized protocol is needed to allow comparison between centers.

'She's not obese, she's a normal 5-year-old and she keeps up with the other kids': families' reasons for not attending a family-based obesity management programme.

AIMS: To discover the reasons behind invited families' lack of engagement with a family-based childhood obesity programme in a deprived area. METHODS: Interviews were conducted with 10 families who were invited to join the programme, but declined to engage. There were two distinct subgroups of participants: those who had no interest in attending the programme and those who showed initial interest yet did not continue attending. The two subgroups were analyzed separately using inductive thematic analysis, and then compared. RESULTS: Analysis identified eight themes overall. For both groups, when the service was perceived to be not needed ('I didn't see how that would help'), the families disengaged with it. For both groups, this perception was partly related to the perceived appearance of their children: either that they were not obese ('I didn't think my son was overweight') or that they were growing into their size. There was also a similarity in both groups that they perceived that they were already following healthy lifestyles. In addition, several of the themes arising from the families who had no initial interest were related to the impact of the letter that parents received detailing the result of their child being weighed and measured at school. This angered parents ('I was disgusted'), and there was a feeling that the approach was too generic. CONCLUSION: This study identified a number of potential reasons behind why families may decline to engage with a childhood obesity programme in a deprived area. Across all families, if the programme was perceived as not needed, they would disengage. For those who did not engage at all, the initial communication of the child's body mass index (BMI) is crucial. Recommendations include taking a more personal and tailored approach for the initial communication and shifting the focus of the programmes onto healthier lifestyles.

Considering BMI, body image and desired weight change for suitable obesity management options

With prevalence of obesity increasing worldwide, understanding body image in individuals with excessive weight is important, as unawareness of weight excess can prevent weight loss attempts. We explored the associations among measured and self-reported body mass index (BMI), body image and body satisfaction among Spanish females and males with overweight or obesity, with a special focus in discriminating individuals who are and are not satisfied with their body and wish or not to change their appearance. Just unifying all individuals with excessive weight may lead to uncover or deny different realities and to develop unfitted clinical management options. Updating findings for the Spanish population, we found that most participants correctly estimated their weight, but 3 in 10 underestimated it. Similarly, their body images corresponded to adults with overweight or obesity who desired to be thinner, but in average they reported a perceived body just slightly overweight and a moderate satisfaction with their body. Complementing the existing evidence, BMI and sex-gender interacted for influencing body weight estimation and desired weight change. In addition, three different subgroups were found for desired change of weight and size, depending on their BMI and body satisfaction. Discovering and considering different subjective realities and corporeal experiences among individuals with weight excess will help professionals to develop appropriate therapeutic interventions. Thus, the personal experiences that individuals have with obesity, instead of obesity itself, should be considered for disentangling management efforts

Family-based, healthy living intervention for children with overweight and obesity and their families: a 'real world' trial protocol using a randomised wait list control design.

INTRODUCTION: Family-based behavioural weight management interventions are efficacious and widely used to address childhood obesity. Curriculum and strategies vary extensively and scale-up often depends on ensuring that the intervention fits the adoption context. AIMS AND OBJECTIVES: To evaluate the impact and implementation of a 'made in British Columbia' (BC) family-based early intervention programme (EIP) for 8-12 years old with overweight and obesity and their families. METHODS AND ANALYSIS: A randomised waitlist-control trial will assess a 10-week interactive, family-based lifestyle intervention followed by four maintenance sessions, in BC, Canada. We aim to enrol 186 families. The blended intervention includes at least 26 contact hours between participants and programme providers, including interactive activities and educational materials through weekly 90-min group sessions, an online family portal, and self-directed family activities. Curricular content includes information and activities related to healthy eating, physical activity (PA), positive mental health, parenting practices and sleep hygiene. The waitlist control group will receive a modified programme with the same 10-week sessions in the family portal, and four group sessions. Families participate in data collection at baseline, postintervention (week 10) and follow-up (week 18). The primary outcome is to assess changes in child body mass index z-score at 10 weeks between the groups. Secondary outcomes include changes at 10 weeks between the groups in child and parent PA behaviour and skills, healthy eating behaviour, and mental health. Process evaluation will address reach, implementation and maintenance (baseline, 10-week and 18-week) using recruitment tracking forms, parent questionnaire, programme attendance tracking forms, leader feedback surveys, parents and children satisfaction surveys and postprogramme interviews with facilitators, stakeholders and parents. Intention-to-treat analyses will be conducted. Process evaluation will be analysed thematically. ETHICS AND DISSEMINATION: Study procedures were designed to address research and community needs and will follow ethical standards. TRIAL REGISTRATION NUMBER: NCT03643341.

Creating a long-term future for big data in obesity research.

Big data are part of the future in obesity research. The ESRC funded Strategic Network for Obesity has together generated a series of papers, published in the International Journal for Obesity illustrating various aspects of their utility, in particular relating to the large social and environmental drivers of obesity. This article is the final part of the series and reflects upon progress to date and identifies four areas that require attention to promote the continued role of big data in research. We additionally include a 'getting started with big data' checklist to encourage more obesity researchers to engage with alternative data resources.

Duodenal switch in revisional bariatric surgery: conclusions from an expert consensus panel.

BACKGROUND: Duodenal switch (BPD/DS) is gaining popularity as a secondary procedure for inadequate weight loss after an initial operation. OBJECTIVES: We aimed to generate expert consensus points on the appropriate use of BPD/DS in the revisional bariatric surgical setting. SETTING: Data were gathered at an international conference with attendees from a variety of different institutions and settings. METHODS: Sixteen lines of questioning regarding revisional BPD/DS were presented to an expert panel of 29 bariatric surgeons. Current available literature was reviewed extensively for each topic and proposed to the panel before polling. Responses were collected and topics defined as achieving consensus (≥70% agreement) or no consensus (<70% agreement). RESULTS: Consensus was present in 10 of 16 lines of questioning, with several key points most prominent. CONCLUSIONS: As a second-stage procedure, BPD/DS is most appropriate after sleeve gastrectomy (SG) for the treatment of super morbid obesity (96.7% agree) or as a subsequent operation for a reliable patient with insufficient weight loss after SG (88.5%). In a patient with weight regain and reflux and/or enlarged fundus after SG, Roux-en-Y gastric bypass is preferable and BPD/DS should be avoided (90%). BPD/DS should not be used prophylactically in patients with a history of jejunoileal bypass who are otherwise doing well (80.8%). Applicability of BPD/DS is limited by technical difficulty; 86.2% of experts would routinely recommend or consider the procedure if it were more technically feasible after failed bypass. No consensus was found on approaches to revision of BPD/DS for protein malnutrition.

Effects of an Intensive Inpatient Rehabilitation Program in Elderly Patients with Obesity.

OBJECTIVE: The aim of this study was to assess the short-term effectiveness of an intensive inpatient multidimensional rehabilitation program (MRP), including diet, exercise, and behavioral therapy, in elderly patients with severe obesity. METHODS: Forty-four elderly patients (old; age 69.3 ± 3.5 years, BMI 41.9 ± 14.9) were analyzed against 215 younger patients (young; age 48.2 ± 18.5 years, BMI 43.9 ± 9.4), who were used as controls. All patients underwent MRP, based on group therapy guided by a multidisciplinary team (physicians, dietitians, exercise trainers, psychologists). We evaluated changes in anthropometry, cardiovascular risk factors, physical fitness, quality of life, and eating behavior. RESULTS: After 3 weeks of MRP, we observed a reduction in body weight (old -3.8%, young -4.3%), BMI (old -3.9%, young -4.4%), waist circumference (old -3.4%, young -4.1%), total cholesterol (old -14.0%, young -15.0%), and fasting glucose (old -8.3%, young -8.1%), as well as improved performance in the Six-Minute-Walk Test (old +28.7%, young +15.3%), chair-stand test (old +24.8%, young +26.9%), and arm-curl test (old +15.2%, young +27.3%). Significant improvement was registered in all other analyzed domains. CONCLUSION: Our 3-week MRP provided significant clinical and functional improvement, which was similar between elderly and younger patients with severe obesity. In the long-term, this may be translated into better quality of life, through better management of obesity-associated morbidities and reduced frailty.

European Practical and Patient-Centred Guidelines for Adult Obesity Management in Primary Care.

The first contact for patients with obesity for any medical treatment or other issues is generally with General Practitioners (GPs). Therefore, given the complexity of the disease, continuing GPs' education on obesity management is essential. This article aims to provide obesity management guidelines specifically tailored to GPs, favouring a practical patient-centred approach. The focus is on GP communication and motivational interviewing as well as on therapeutic patient education. The new guidelines highlight the importance of avoiding stigmatization, something frequently seen in different health care settings. In addition, managing the psychological aspects of the disease, such as improving self-esteem, body image and quality of life must not be neglected. Finally, the report considers that achieving maximum weight loss in the shortest possible time is not the key to successful treatment. It suggests that 5-10% weight loss is sufficient to obtain substantial health benefits from decreasing comorbidities. Reducing waist circumference should be considered even more important than weight loss per se, as it is linked to a decrease in visceral fat and associated cardiometabolic risks. Finally, preventing weight regain is the cornerstone of lifelong treatment, for any weight loss techniques used (behavioural or pharmaceutical treatments or bariatric surgery).

Estresse de aculturação e carga alostática entre mulheres imigrantes mexicanas / Acculturation stress and allostatic load among Mexican immigrant women / Estrés aculturativo y carga alostática en las mujeres inmigrantes mexicanas

Objetivos este estudo de caso-controle comparou os níveis de estresse e carga alostática (CA) entre mulheres mexicanas nos EUA ( n = 19) e no México ( n = 40). Método medidas de estresse incluíram a Escala de Estresse Percebido (EEP) e a Escala de Estresse Social das Mulheres Hispânicas (EESMH). Uma medida composta por 8 indicadores de CA (pressão arterial sistólica e diastólica, índice de massa corporal (IMC), relação cintura-quadril, colesterol total, hemoglobina glicada (hemoglobina A1C), triglicerídeos e proteína C-reativa) foi calculada. Resultados não houve diferenças significativas entre os grupos na CA entre mulheres mexicanas imigrantes e não imigrantes ( t = 1,55, p = 0,126). Uma análise fatorial de componentes principais foi realizada nos 8 indicadores de CA; uma solução de 2 fatores explicou 57% da variância. As diferenças entre grupo nos dois fatores CA foram analisadas usando MANOVA. O IMC e a relação cintura-quadril foram menores, mas a pressão arterial e os triglicerídeos foram maiores no grupo dos EUA e foram mediados pelo tempo nos EUA. O maior estresse de aculturação foi significativamente relacionado ao aumento da relação cintura-quadril ( r = 0,57, p = 0,02). Considerações finais os resultados sugerem que algumas medidas de CA aumentam com o tempo nos EUA e o estresse de aculturação pode ser um fator significativo.

Objectives this case-control study compared levels of stress and allostatic load (AL) among Mexican women in the US ( n =19) and Mexico ( n = 40). Method measures of stress included the Perceived Stress Scale (PSS) and the Hispanic Women's Social Stressor Scale (HWSSS). A composite measure of 8 indicators of AL (systolic and diastolic blood pressure, body mass index (BMI), waist-to-hip ratio, total cholesterol, glycated hemoglobin (hemoglobin A1C), triglycerides and C-reactive protein) was calculated. Results there were no significant group differences in AL between Mexican and Mexican immigrant women ( t = 1.55, p = .126). A principal component factor analysis was conducted on the 8 AL indicators; a 2-factor solution explained 57% of the variance. Group differences in the two AL factors were analyzed using MANOVA. BMI and waist-to-hip ratios were lower, but blood pressure and triglycerides were higher in the US group and were mediated by time in the US. Greater acculturation stress was significantly related to increased waist-to-hip ratio ( r = .57, p = .02). Final remarks findings suggest some measures of AL increased with time in the US, and acculturation stress may be a significant factor.

Objetivos este estudio de casos y controles ha comparado los niveles de estrés y carga alostática (CA) en mujeres mexicanas en los EE.UU. ( n = 19) y México ( n = 40). Método las medidas de estrés incluyeron la Escala de Estrés Percibido (EEP) y la Escala de Estrés Social de las Mujeres Hispanas (HWSSS, por sus siglas en inglés). Se calculó una medida compuesta de 8 indicadores de CA (presión arterial sistólica, presión arterial diastólica, índice de masa corporal (IMC), relación cintura/cadera, colesterol total, hemoglobina glicosilada (HbA1c), triglicéridos, y proteína C reactiva). Resultados no hubo diferencias significativas de CA entre los grupos de mujeres mexicanas e inmigrantes mexicanas ( t = 1,55, p = 0,126). Se realizó un análisis factorial de componente principal de los 8 indicadores de CA; una solución de 2 factores explicó el 57% de la varianza. Las diferencias de grupo en los dos factores de CA se analizaron utilizando MANOVA. El IMC y la relación cintura/cadera disminuyeron, pero la presión arterial y los triglicéridos aumentaron en el grupo de los EE.UU. y estuvieron influenciados por el tiempo de residencia en los EE.UU. Un mayor estrés aculturativo se relacionó significativamente con el aumento de la relación cintura/cadera (r = 0,57, p = 0,02). Comentarios finales los hallazgos sugieren que algunas medidas de CA aumentan con el tiempo de residencia en los EE.UU. y el estrés aculturativo puede ser un factor importante.

IFSO Worldwide Survey 2016: Primary, Endoluminal, and Revisional Procedures.

BACKGROUND AND AIM: The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), being a Federation of 62 national societies, is the ideal network to monitor the number and type of procedures at a global level. The IFSO survey, enriched with a special section on revisional procedures, aims to report the number and types of bariatric procedures performed worldwide in 2016 and analyzes the surgical trends from 2008 to 2016. METHODS: The 2016 IFSO Survey form was emailed to all IFSO societies. Each Society was requested to indicate the number and type of bariatric procedures performed in the country. Trend analyses from 2008 to 2016 were also performed. RESULTS: The total number of bariatric/metabolic procedures performed in 2016 was 685,874; 634,897 (92.6%) of which were primary and 50,977 were revisional (7.4%). Among the primary interventions, 609,897 (96%) were surgical and 25,359 (4%) were endoluminal. The most performed primary surgical bariatric/metabolic procedure was sleeve gastrectomy (SG) (N = 340,550; 53.6%), followed by Roux-en-Y gastric bypass (N = 191,326; 30.1%), and one-anastomosis gastric bypass (N = 30,563; 4.8%). CONCLUSIONS: In 2016, there was an increase in the total number both of surgical and endoluminal bariatric/metabolic procedures. Revisional procedures represent about 7% of the total bariatric interventions. SG remains the most performed surgical procedure in the world.

Primary Care Provider Knowledge and Practice Patterns Regarding Childhood Obesity.

BACKGROUND: We aimed to evaluate current childhood obesity management by providers and improve management of pediatric obesity through a provider-focused educational intervention. METHODS: We surveyed family medicine and pediatric providers regarding documentation and intervention, knowledge gaps, and educational needs for childhood obesity. An educational program was implemented regarding detection, documentation, and follow-up/referral of pediatric obesity and comorbid conditions. We reviewed charts for 50 overweight or obese children before and after intervention. RESULTS: The survey identified lack of time (73%) and perception of parents (77%) as the most frequent provider barriers to pediatric obesity care. Provider referrals increased from 6% to 16% after intervention, and laboratory testing increased from 14% to 26%. No changes were noted in discussion of weight status, diagnosis/documentation, or billing. CONCLUSION: Provider education can improve appropriate ordering of laboratory studies and referrals for overweight children. Different intervention approaches may improve billing and documentation practices for pediatric obesity.

Obesity Management Task Force of the European Association for the Study of Obesity Released "Practical Recommendations for the Post-Bariatric Surgery Medical Management".

Bariatric patients may face specific clinical problems after surgery, and multidisciplinary long-term follow-up is usually provided in specialized centers. However, physicians, obstetricians, dieticians, nurses, clinical pharmacists, midwives, and physical therapists not specifically trained in bariatric medicine may encounter post-bariatric patients with specific problems in their professional activity. This creates a growing need for dissemination of first level knowledge in the management of bariatric patients. Therefore, the Obesity Management Task Force (OMTF) of the European Association for the Study of Obesity (EASO) decided to produce and disseminate a document containing practical recommendations for the management of post-bariatric patients. The list of practical recommendations included in the EASO/OMTF document is reported in this brief communication.
