"Vicious circles": the development of morbid obesity

Structured lifestyle modification as an adjunct to obesity pharmacotherapy: there is much to learn

We are at the start of an exciting new era of very effective pharmacotherapy for patients with obesity, with the latest generation of drugs approaching the efficacy of obesity surgery. Clinical trials of obesity drugs tend to emphasise the importance of participation in some form of structured lifestyle intervention for all trial participants. This usually consists of advice to reduce calorie intake and increase moderate to vigorous physical activity. There is strong evidence that structured lifestyle modification programmes improve health in patients with obesity and related disorders. However, there is no specific evidence that they improve the response to obesity medications. This is because of the way that drug trials for patients with obesity have traditionally been designed, with participants in the active drug treatment group being compared to participants on placebo drug treatment, but with both groups always receiving the same structured lifestyle intervention. While this approach is entirely reasonable, it makes it impossible to draw any inferences about the efficacy of structured lifestyle modification to augment the response to drug therapy. Given this genuine equipoise, a critical step in ensuring that our treatment of patients with obesity is robustly evidence-based is to determine whether "drug plus lifestyle" offer any advantage over "drug plus placebo" in large, well-designed and adequately powered clinical trials. We also need to determine the cost-effectiveness of these programmes.

Addressing uncertainty about the role of structured lifestyle modification for metabolic surgery patients

There is good evidence that structured lifestyle modification programmes improve health in patients with metabolic and cardiovascular disorders, but there is no specific evidence that they improve outcomes in patients undergoing metabolic or obesity surgery. Despite expert consensus guidelines stating this fact, some healthcare systems still compel patients to participate in a structured lifestyle modification programme prior to metabolic or obesity surgery. There is a well-established need for individualised multidisciplinary dietetic and physical activity care for metabolic and obesity surgery patients, and the benefits of intentional weight loss prior to surgery are well proven, but these are distinct from potentially harmful requirements for patients to undertake compulsory structured lifestyle programmes of fixed duration, frequency and intensity, which may delay surgery and reinforce obesity stigma. A critical step in rejuvenating metabolic surgery is to reframe patient participation in structured lifestyle modification programmes as an opportunity for education and empowerment, not as an indicator of motivation or suitability for metabolic surgery. Large, well-designed and adequately powered clinical trials are needed to address uncertainties in the evidence base for these programmes. Given genuine equipoise, they will need to determine whether "surgery plus lifestyle" is superior to "surgery plus placebo". Moreover, they will need to determine the cost-effectiveness of these programmes and identify some of the factors giving rise to the substantial heterogeneity in responses to structured lifestyle modification.

Effect of Laparoscopic Sleeve Gastrectomy on Quality of Life

PURPOSE

The clinical benefits of bariatric surgery are well-established, but the impact of bariatric surgery on psychosocial outcomes such as health-related quality of life (HRQL) is less clear. The aim of this study is to assess the Quality of life (QOL) as a whole and in separate domains in post-bariatric surgery patients.

METHODOLOGY

A single unit cross-sectional analysis of a prospective study is done on QOL in 51 patients undergoing laparoscopic sleeve gastrectomy at tertiary hospital. QOL was assessed by WHOQOL-BREF (World Health Organisation Quality of Life questionnaire -Brief version) questionnaire and Global Quality of Life Scale in each patient. Scores were calculated on a 0-100 scale and results compared.

RESULTS

The median scores given by patients before surgery were 14, 21, 42, 40 and 12.5 for each of the parameters physical, psychological, social, environmental and overall well-being respectively. The median scores for after surgery were 86, 87, 91, 88 and 87.5 respectively. The difference was significant (p value 0.001). Global QOL after surgery, calculated year wise, showed QOL scores of 90, 100, 95 and 80 in patients with 1 year, 2 years, 3 years and 4 years of follow-up without any significant difference (p value 0.502).

CONCLUSION

Through this study, we emphasize the need for the selection of a standardised scale by international organisations to compare the different studies. By proving the significant differences in the QOL of patients who underwent LSG [laparoscopic sleeve gastrectomy], we suggest to consider the Quality of Life as one of the criteria to consider a patient for bariatric surgery.

Health professionals' reflections on existential concerns among people with obesity

PURPOSE

This study aimed to describe health professionals' reflections on existential concerns among people with obesity when attempting to support them in their lifestyle change processes. For many of those affected by obesity, the condition becomes lifelong and causes existential concerns. The health professionals' reflections on existential concerns among people with obesity may influence central aspects of their practice and their patients' well-being.

METHODS

Eighteen health professionals with relevant health education working in three different treatment programmes for people with obesity were recruited for three focus group interviews. The interviews were analysed and interpreted using a model for interpretation of meaning at three levels with a phenomenological-hermeneutical approach.

FINDINGS

The analysis identified three themes. The health professionals reflected on existential concerns among people with obesity in terms of patients' repressed emotional difficulties and lack of self-respect. In addition, they reflected on their own experiences of powerlessness when presented with people with obesity's existential concerns.

CONCLUSION

The present study provides valuable insights into reflections on existential concerns among people with obesity, based on health professionals' descriptions. We believe that these insights add to the existing literature and have consequences for how people with obesity are met and cared for.

What is it like to live with obesity in Peninsular Malaysia? A qualitative study

Understanding the experience of people living with obesity is crucial for delivering holistic care relevant to the socio-cultural context. Although half of the Malaysian adults have excessive weight, the lived experience of people with obesity in the Malaysian context is not well studied. Using the principles of hermeneutic phenomenology, this study explores the lived experience of adults with obesity in Malaysia and their perspective on the environmental influences on obesity. Participants were adults from Peninsular Malaysia living with obesity recruited from social media, clinics and snowball sampling. Twenty-five teleconference interviews in Malay were audio-recorded and transcribed verbatim. Data were analysed inductively using a reflexive thematic analysis approach, and quotes were translated into English. We identified five themes: (1) Malaysian life is centred around food; (2) social norms shape people living with obesity's perceptions of themselves and obesity; (3) people living with obesity are physically restricted by their body; (4) people living with obesity have repeated thoughts about efforts to lose weight; and (5) stigmatization of people living with obesity leads to negative emotions. Socio-cultural influences were highly impactful on participants' lifeworld, and these influences need to be considered in clinical practice and policy for obesity management in Malaysia. Clinical management should focus on assisting patients in navigating the unsupportive food and social environment instead of overfocusing on the individual's responsibility for weight reduction.

Quality of Life after Bariatric Surgery-A Systematic Review

Background: Most studies analyzing the health-related quality of life (HRQOL) after bariatric treatment ceased at five years post-surgery or even earlier, and it is unclear whether the HRQOL benefit persists for a longer time. This paper reviews sparse evidence regarding HRQOL in patients who underwent bariatric surgery at least nine years prior. Materials and Methods: A of PubMed, Scopus and Google Scholar between 2007–2021 was carried out for the studies investigating HRQOL as an outcome measure in patients after bariatric surgery of any type and having at least a 9-year follow-up. Inconsistent reporting of weight loss or postgraduate study results unrelated to QoL were not included in the study. The study used the PICO procedure. Results: The review of 18 identified publications demonstrated that bariatric treatment seems to provide a persistent benefit in terms of HRQOL, especially its physical component score. Due to psychological predispositions, some patients appear to be less likely to benefit from bariatric treatment, whether in terms of HRQOL or bodyweight reduction. Inconsistent and imprecise studies may limit the evidence included in a review. Conclusions: The early identification of such patients and providing them with holistic care, including psychological intervention, would likely further improve the outcomes of bariatric treatment.

The influence of social relationships and activities on the health of adults with obesity: A qualitative study

Background

Obesity in adults is a leading health challenge that causes millions of deaths worldwide and represents a risk factor for developing long‐term conditions. Social relationships are one of the multiple drivers shaping obesity and obesity‐related practices. However, there is still little evidence as to the processes by which relationships influence the adoption of positive and negative obesity health‐related practices—eating, physical activity and alcohol intake. This study aims first to identify the types of relationships relevant to the adoption of practices in adults with obesity and, second, to explore the type of activities these relationships engage with or promote to produce those practices and their potential health consequences.

Methods

Nineteen adults who have or had a history of obesity living in the United Kingdom were interviewed between May 2020 and March 2021. Experiences were explored through semi‐structured interviews and network mapping via videoconferencing. Data were analysed using a hermeneutic phenomenology informed thematic analysis.

Results

Three main themes were identified: (1) everyday familial routines matter, (2) chasing healthier lifestyles: comparing, modelling and connecting emotionally with friends and (3) healthcare professionals as negative influencers.

Discussion and Conclusions

Findings show how different types of relationships might shape the risk of developing and losing weight. They uncover the power of informal networks (family and friends) and highlight the potentially negative impact of formal ones (healthcare professionals). Our exploration could add to arguments about the need for stakeholders confronting obesity to be aware of the relevance of everyday social relationships in health and well‐being strategies for tackling the issue, in creating collective and individual person‐centred long‐term sustainable actions.

Patient and Public Contribution

Feedback on the tone/content of the interview questions was provided by the two first participants. The results were checked and received feedback from one of the interviewees.

The lived experience of patients with obesity: A systematic review and qualitative synthesis

Although the deleterious effects of obesity have been well documented in terms of morbidity and mortality, less is known about what it is like to live with this complex and chronic disease. This study systematically reviewed and synthesized peer-reviewed studies relating to the lived experience of patients with obesity. A total of 12,388 records were screened, resulting in the inclusion of 32 final studies. Meta-ethnographic synthesis of these 32 studies generated five "third-order constructs" or themes: the development of obesity; a life limited; stigma, judgment, shame, and blame; treatment and; experiences of specific or minority groups. These constructs describe, from the patient's perspective, the factors associated with the development and maintenance of obesity; the effects of the disease on their day-to-day lives; the impact of the stigma and judgment many patients are subjected to; and their experience of accessing, or trying to access, treatment for their healthcare needs. This synthesis reveals the dearth of studies that focus solely on the experience of the patient and highlights the tendency for participant-informed, rather than participatory, methods in obesity research. It concludes with a call for further participatory research into the experiences of people living with obesity.

"You Are Always at War With Yourself" The Perceptions and Beliefs of People With Obesity Regarding Obesity as a Disease

Obesity as a disease remains poorly understood by key stakeholders. Here, in people living with severe obesity, perceptions and beliefs relating to obesity as a disease and obesity causality were examined. Semi-structured interviews were conducted in a tertiary care obesity clinic. 23 people with obesity (10 males, 13 females) volunteered. An overall agreement that obesity is a disease was present. Perceptions related to why obesity is and is not a disease were diverse: Lack of control and addiction, biological determinism, and personal responsibility. For weight loss maintenance, the perceptions and beliefs were heterogeneous with biological factors not considered a determinant of success. Instead, exercise, support, and willpower were described as associated with success. Barriers related to remaining in a weight-reduced state included the following: Emotional eating, sustainability of diet, occupational impact, and defeatism due to misaligned expectation and outcome. In conclusion, people living with obesity tend to agree obesity is a disease yet an incomplete understanding of the disease is present.

Structured Lifestyle Modification Prior to Bariatric Surgery: How Much is Enough?

Many healthcare systems require patients to participate in a structured lifestyle modification programme prior to bariatric surgery, even though bariatric consensus guidelines do not recommend this. While there is good evidence that such programmes improve health in other conditions such as metabolic and cardiovascular diseases, there is no evidence that they improve outcomes after bariatric surgery. The distinction needs to be drawn between the well-established need for individualised multidisciplinary dietetic and physical activity care for bariatric surgical patients and the potential harms from mandating participation in compulsory structured lifestyle programmes of fixed duration, frequency and intensity, which may delay surgery, reinforce obesity stigma, or both. Large clinical trials might help to address some of the uncertainty and provide an evidence base for clinicians and policymakers.

Being active when living within a large body: experiences during lifestyle intervention

Background: In-depth understanding of the experiences of both well-being and suffering in relation to being severely obese and becoming active through lifestyle intervention is lacking.Aim: to explore and describe adults' existential experiences of being active, when living within a large body-before and during a lifestyle intervention.Methods: A longitudinal design of repeated individual interviews with 16 adults with BMI ≥40, based on hermeneutic phenomenology, existential philosophy and a theory of well-being was performed. The study was approved by the Danish health authorities.Results: Two dimensions of experiences were found; "Living within a downward spiral" and "Striving for enjoyment and settlement". The themes describing suffering were: 'Sense of being thwarted and defeated ' and "Tackling energy depletion and impact of sense of self". The themes describing well-being were: "Hoping for renewal and energised resoluteness" and "Enduring discomfort and feeling safe".Conclusions: Interacting existential experiences can be facilitators or barriers for physical activity. It seems relevant for health care providers to address the individual's lifeworld experiences of well-being, lack of well-being and suffering. Well-being as a sense of feeling "at home" when physically active may break down an inactivity spiral. Promoting well-being is a legitimate aim of lifestyle intervention.

Health-Related Quality of Life in Bariatric and Metabolic Surgery

PURPOSE OF REVIEW

This review describes the latest evidence for the impact of bariatric surgery on health-related quality of life (HRQL).

RECENT FINDINGS

The impact of bariatric surgery on HRQL is less well-understood than its clinical effectiveness on weight and co-morbidities. Poor-quality study design and different HRQL measures challenge systematic reviews and meta-analyses. Available limited evidence suggests that physical aspects of HRQL may improve more than mental health aspects of HRQL after bariatric surgery, reaching maximal benefits 1-2 years post-surgery. Comparative HRQL analyses between bariatric procedures cannot be made due to a lack of randomised data. Qualitative research highlights the tensions patients experience after bariatric surgery, which provides insights to observed changes in HRQL. Standardized HRQL measures are being developed and agreed to improve future evidence synthesis. Two multi-centre randomised trials of bariatric surgical procedures including detailed HRQL assessment are in progress. It is hoped that the combination of comparative high-quality HRQL data and information from qualitative studies will provide new insights into patient well-being and health after bariatric surgery.

Aspects of well-being when struggling with obesity

Purpose: We aimed to gain deeper insight into how people struggling with obesity handle their life situation by addressing how well-being might unfold. For many people, obesity becomes a lifelong condition characterized by repeated weight fluctuations while their weight increases gradually. From an existential perspective, constantly waiting for weight loss can cause an experience of not reaching one’s full potential. How people with obesity experience well-being, within their perceived limitations, is less reflected in previous research.

Methods: We established a qualitative study using in-depth interviews with seven men and 14 women with obesity (body mass index ³35 kg/m²) aged 18–59 years. The study had an exploratory design including a phenomenological–hermeneutic perspective, with a lifeworld approach.

Results: Three themes describing aspects of well-being were developed: coming to terms with the body, restoring the broken relational balance and reorienting the pivot in life. The thematic findings were abstracted into a main theme: striving to make living bearable. The movement towards well-being can be seen as a struggle towards an experience of balance to make bearable living.

Conclusions: We suggest that well-being as a dialectic between vulnerability and freedom might become a health-facilitating experience for people struggling with obesity.

Transforming Health Experience and Action through Shifting the Narrative on Obesity in Primary Care Encounters

We sought to understand the impact of primary care conversations about obesity on people's everyday life health experience and practices. Using a dialogic narrative perspective, we examined key moments in three very different clinical encounters, the patients' journals, and follow-up interviews over several weeks. We trace how people living with obesity negotiate narrative alternatives that are offered during clinical dialogue to transform their own narrative and experience of obesity and self. Findings provide pragmatic insights into how providers can play a significant role in shifting narratives about obesity and self and how such co-constructed narratives translate into change and tangible health outcomes in people's lives.

Living with obesity - existential experiences

Aims and objectives: The aim was to gain in-depth understanding about individuals’ existential experiences of living with obesity.

Background: People living with obesity face great vulnerability and existential challenges. The different treatments offered do not seem to meet the individual needs of persons with obesity. A deeper understanding of existential experiences from an individual perspective is needed to individualize treatment.

Design: An exploratory phenomenological–hermeneutical design was used to gain a greater understanding of the existential experiences involved in living with obesity.

Methods: The participants represented a convenient sample. 18 qualitative interviews were conducted and subjected to phenomenological–hermeneutical analysis.

Results: Four themes emerged: shaped by childhood; captured by food; depressed by the culture; and judged by oneself.

Conclusions: The burden of being obese can be experienced as being objectified and alienated as a human being. We need to turn towards a life-world perspective, seeing each human being as a living body to overcome objectification and alienation, and then move them towards becoming subjects in their own lives, through giving space for self-love. Health care workers need to assist persons living with obesity to reduce objectification and alienation. It is important to develop intervention that has an individual, holistic approach.

Patients' experiences of life after bariatric surgery and follow-up care: a qualitative study

OBJECTIVES

Bariatric surgery is the most clinically effective treatment for people with severe and complex obesity, however, the psychosocial outcomes are less clear. Follow-up care after bariatric surgery is known to be important, but limited guidance exists on what this should entail, particularly related to psychological and social well-being. Patients' perspectives are valuable to inform the design of follow-up care. This study investigated patients' experiences of life after bariatric surgery including important aspects of follow-up care, in the long term.

DESIGN

A qualitative study using semistructured individual interviews. A constant comparative approach was used to code data and identify themes and overarching concepts.

SETTING

Bariatric surgery units of two publicly funded hospitals in the South of England.

PARTICIPANTS

Seventeen adults (10 women) who underwent a primary operation for obesity (mean time since surgery 3.11 years, range 4 months to 9 years), including Roux-en-Y gastric bypass, adjustable gastric band and sleeve gastrectomy, agreed to participate in the interviews.

RESULTS

Experiences of adapting to life following surgery were characterised by the concepts of 'normality' and 'ambivalence', while experiences of 'abandonment' and 'isolation' dominated participants' experiences of follow-up care. Patients highlighted the need for more flexible, longer-term follow-up care that addresses social and psychological difficulties postsurgery and integrates peer support.

CONCLUSIONS

This research highlights unmet patient need for more accessible and holistic follow-up care that addresses the long-term multidimensional impact of bariatric surgery. Future research should investigate effective and acceptable follow-up care packages for patients undergoing bariatric surgery.

How Ethical Is Our Current Delivery of Care to Patients with Severe and Complicated Obesity?

Despite overwhelming evidence that bariatric interventions reduce morbidity and mortality and are cost-effective, access for affected patients is limited. We sought to describe the extent to which health policy makers and publically funded health services have an ethical obligation to provide bariatric care. We conducted a narrative review of the literature pertaining to the efficacy, safety, and cost-effectiveness of bariatric surgical interventions, in the context of the core principles of medical ethics. We found that in relation to autonomy (i.e., the right to self-determination), beneficence, non-maleficence, and justice (i.e., the obligation to provide fair and equitable treatment to all patients), the current provision of bariatric surgical care fell short of meeting internationally recognized medical ethical standards. These findings have important implications for government policy and healthcare resource allocation. Respecting the individual’s right of self-determination, to do good, prevent harm, and provide equity in access to services is paramount, even when that individual is obese.

Acceptability and feasibility of weight management programmes for adults with severe obesity: a qualitative systematic review

OBJECTIVES

To improve our understanding of the acceptability of behavioural weight management programmes (WMPs) for adults with severe obesity.

DESIGN

A systematic review of qualitative evidence.

DATA SOURCES

Medline, Embase, PsycINFO, CINAHL, SCI, SSCI and CAB abstracts were searched from 1964 to May 2017.

ELIGIBILITY CRITERIA

Papers that contained qualitative data from adults with body mass index (BMI) ≥35 kg/m² (and/or the views of providers involved in their care) and considered issues about weight management.

DATA EXTRACTION AND SYNTHESIS

Two reviewers read and systematically extracted data from the included papers which were compared, and contrasted according to emerging issues and themes. Papers were appraised for methodological rigour and theoretical relevance using Toye's proposed criteria for quality in relation to meta-ethnography.

RESULTS

33 papers met our inclusion criteria from seven countries published 2007-2017. Findings were presented from a total of 644 participants and 153 programme providers. Participants described being attracted to programmes that were perceived to be novel or exciting, as well as being endorsed by their healthcare provider. The sense of belonging to a group who shared similar issues, and who had similar physiques and personalities, was particularly important and seemed to foster a strong group identity and related accountability. Group-based activities were enjoyed by many and participants preferred WMPs with more intensive support. However, some described struggling with physical activities (due to a range of physical comorbidities) and not everyone enjoyed group interaction with others (sometimes due to various mental health comorbidities). Although the mean BMI reported across the papers ranged from 36.8 to 44.7 kg/m², no quotes from participants in any of the included papers were linked to specific detail regarding BMI status.

CONCLUSIONS

Although group-based interventions were favoured, people with severe obesity might be especially vulnerable to physical and mental comorbidities which could inhibit engagement with certain intervention components.

A qualitative study exploring the views of individuals with knee osteoarthritis on the role of physiotherapists in weight management: A complex issue requiring a sophisticated skill set

OBJECTIVES

The aim of the present study was to explore the attitudes of individuals with knee osteoarthritis (OA) towards the role of physiotherapists in weight management in knee OA.

METHODS

The study took the form of a qualitative semi-structured telephone interview study. Participants included 13 purposively sampled individuals with symptomatic knee OA who were overweight or obese by body mass index. Each participated in a semi-structured telephone interview exploring their perspectives regarding the potential role of physiotherapists in weight management in knee OA. Data were transcribed and analysed using a thematic approach.

RESULTS

Three main themes were identified, which highlighted that individuals with knee OA: (a) recognize that weight management is complex; (b) consider that a special skill set is required by clinicians for weight management; and (c) expressed ambivalence towards physiotherapists' role in weight management, with a focus on the role of exercise prescription.

CONCLUSIONS

Although participants were open to physiotherapists taking on a weight management role within a multidisciplinary team, they were uncertain about whether physiotherapists had the skills and scope of practice needed to address this complex issue. The findings highlight the importance of engagement by physiotherapists in meaningful dialogue with patients, to understand better their experiences, expectations and preferences, and establish if, when and how to integrate patients in weight management discussions in the treatment plan for their knee OA.

Bariatric surgery, lifestyle interventions and orlistat for severe obesity: the REBALANCE mixed-methods systematic review and economic evaluation

BACKGROUND

Adults with severe obesity [body mass index (BMI) of ≥ 35 kg/m2] have an increased risk of comorbidities and psychological, social and economic consequences.

OBJECTIVES

Systematically review bariatric surgery, weight-management programmes (WMPs) and orlistat pharmacotherapy for adults with severe obesity, and evaluate the feasibility, acceptability, clinical effectiveness and cost-effectiveness of treatment.

DATA SOURCES

Electronic databases including MEDLINE, EMBASE, PsycINFO, the Cochrane Central Register of Controlled Trials and the NHS Economic Evaluation Database were searched (last searched in May 2017).

REVIEW METHODS

Four systematic reviews evaluated clinical effectiveness, cost-effectiveness and qualitative evidence for adults with a BMI of ≥ 35 kg/m2. Data from meta-analyses populated a microsimulation model predicting costs, outcomes and cost-effectiveness of Roux-en-Y gastric bypass (RYGB) surgery and the most effective lifestyle WMPs over a 30-year time horizon from a NHS perspective, compared with current UK population obesity trends. Interventions were cost-effective if the additional cost of achieving a quality-adjusted life-year is < £20,000-30,000.

RESULTS

A total of 131 randomised controlled trials (RCTs), 26 UK studies, 33 qualitative studies and 46 cost-effectiveness studies were included. From RCTs, RYGB produced the greatest long-term weight change [-20.23 kg, 95% confidence interval (CI) -23.75 to -16.71 kg, at 60 months]. WMPs with very low-calorie diets (VLCDs) produced the greatest weight loss at 12 months compared with no WMPs. Adding a VLCD to a WMP gave an additional mean weight change of -4.41 kg (95% CI -5.93 to -2.88 kg) at 12 months. The intensive Look AHEAD WMP produced mean long-term weight loss of 6% in people with type 2 diabetes mellitus (at a median of 9.6 years). The microsimulation model found that WMPs were generally cost-effective compared with population obesity trends. Long-term WMP weight regain was very uncertain, apart from Look AHEAD. The addition of a VLCD to a WMP was not cost-effective compared with a WMP alone. RYGB was cost-effective compared with no surgery and WMPs, but the model did not replicate long-term cost savings found in previous studies. Qualitative data suggested that participants could be attracted to take part in WMPs through endorsement by their health-care provider or through perceiving innovative activities, with WMPs being delivered to groups. Features improving long-term weight loss included having group support, additional behavioural support, a physical activity programme to attend, a prescribed calorie diet or a calorie deficit.

LIMITATIONS

Reviewed studies often lacked generalisability to UK settings in terms of participants and resources for implementation, and usually lacked long-term follow-up (particularly for complications for surgery), leading to unrealistic weight regain assumptions. The views of potential and actual users of services were rarely reported to contribute to service design. This study may have failed to identify unpublished UK evaluations. Dual, blinded numerical data extraction was not undertaken.

CONCLUSIONS

Roux-en-Y gastric bypass was costly to deliver, but it was the most cost-effective intervention. Adding a VLCD to a WMP was not cost-effective compared with a WMP alone. Most WMPs were cost-effective compared with current population obesity trends.

FUTURE WORK

Improved reporting of WMPs is needed to allow replication, translation and further research. Qualitative research is needed with adults who are potential users of, or who fail to engage with or drop out from, WMPs. RCTs and economic evaluations in UK settings (e.g. Tier 3, commercial programmes or primary care) should evaluate VLCDs with long-term follow-up (≥ 5 years). Decision models should incorporate relevant costs, disease states and evidence-based weight regain assumptions.

Experiences of accessing obesity surgery on the NHS: a qualitative study

Background

Although surgical treatment is recommended for morbid obesity where other interventions have failed, there is evidence that access to NHS surgery is heavily rationed. This study aimed to investigate how patients experienced accessing referrals for obesity surgery.

Methods

Data collection was undertaken using in-depth interviews with patients and clinicians working in a specialist secondary care facility, and analysis took a constant comparative approach.

Results

Twenty-two participants with morbid obesity were followed up for a period of up to 3 years. All participants had made multiple attempts to lose weight prior to consulting their GPs yet felt this was rarely acknowledged by clinicians. Participants were frustrated when they received insufficient support to comply with primary care interventions, and when it came to obtaining a referral to secondary care, most had to raise this issue with GPs themselves.

Conclusions

There is an urgent need for interventions for morbid obesity in primary care that are accessible to patients to facilitate weight loss and prevent weight re-gain. For those at very high weights, better integration between primary and secondary care is required to ensure appropriate and timely referral for those who need assessment for surgery.

Recipients' and providers' perspectives of obesity and potential barriers to weight management programmes in patients with Rheumatoid Arthritis (RA): a qualitative study

Background

The UK rheumatology community serves an ageing and ethnically diverse population, with a growing public health concern about obesity. Overweight and obesity contribute to 2.8 million preventable deaths annually. A raised Body Mass Index (BMI) in those with Rheumatoid Arthritis (RA) can have a significant negative impact on clinical outcomes. The aim of the study was to examine patients’ and providers’ perceptions of obesity and potential barriers to participation in a future weight management programme to contribute to an appropriate intervention design.

Method

Qualitative semi-structured interviews were carried out with 11 patients with RA and one focus group was held with 8 members of a multi-disciplinary team working in one Rheumatology outpatient clinic. Framework analysis (FA) contributed to the inductive thematic analysis, and was employed to assist with the identification of the emergent codes and final themes.

Results

Three core themes were ascertained from the semi-structured interviews: i) The psychosocial impact of living with RA and obesity, ii) Challenges of living with RA and obesity and iii) Considerations for future weight management programmes. The Focus group analysis also identified three core themes: i) Micro-dynamics between patient and provider, ii) The relationship between the provider and the host institution in relation to the development of a future weight management programme and iii) The social and political context of obesity as a public health concern.

Conclusion

Perceptions of obesity and weight gain and associated barriers to participating in weight management programmes, differ significantly between patients and providers. Patients, require a holistic approach to weight management by clinicians and the acknowledgement of the significant psychosocial impact of a dual diagnosis of RA and being overweight or obese. In contrast, providers seem reluctant to address weight increase with patients and require education and support at an individual and institutional level to integrate weight management into routine care.
