Supporting Weight Management during COVID-19 (SWiM-C): twelve-month follow-up of a randomised controlled trial of a web-based, ACT-based, guided self-help intervention.

Objectives: We developed a guided self-help intervention (Supporting Weight Management during COVID-19, "SWiM-C") to support adults with overweight or obesity in their weight management during the COVID-19 pandemic. This parallel, two-group trial (ISRCTN12107048) evaluated the effect of SWiM-C on weight and determinants of weight management over twelve months.

Methods: Participants (≥18 years, body-mass-index ≥25 kg/m) were randomised to the SWiM-C intervention or to a standard advice group (unblinded).

Effectiveness and cost-effectiveness of referral to a commercial open group behavioural weight management programme in adults with overweight and obesity: 5-year follow-up of the WRAP randomised controlled trial.

Background: There is evidence that commercially available behavioural weight management programmes can lead to short-term weight loss and reductions in glycaemia. Here, we aimed to provide the 5-year impact and cost-effectiveness of these interventions compared with a brief intervention.

Methods: WRAP was a non-blinded, parallel-group randomised controlled trial (RCT).

Acceptability and feasibility of an acceptance and commitment therapy-based guided self-help intervention for weight loss maintenance in adults who have previously completed a behavioural weight loss programme: the SWiM feasibility study protocol.

Introduction: The cost-effectiveness and long-term health impact of behavioural weight management programmes depends on post-treatment weight-loss maintenance. Growing evidence suggests that interventions using acceptance and commitment therapy (ACT) could improve long-term weight management. We developed an ACT-based, guided self-help intervention to support adults who have recently completed a behavioural weight loss programme.

Supporting Weight Management during COVID-19: A Randomized Controlled Trial of a Web-Based, ACT-Based, Guided Self-Help Intervention.

Introduction: Adults with overweight and obesity are vulnerable to weight gain and mental health deterioration during the COVID-19 pandemic. We developed a web-based, guided self-help intervention based on Acceptance and Commitment Therapy (ACT) that aims to support adults with overweight and obesity to prevent weight gain by helping them to manage their eating behaviours, be more physically active, and protect their emotional wellbeing ("SWiM-C"). SWiM-C is a guided self-help programme using non-specialist guides to enhance scalability and population reach while minimizing cost.

Development of a Web-Based, Guided Self-help, Acceptance and Commitment Therapy-Based Intervention for Weight Loss Maintenance: Evidence-, Theory-, and Person-Based Approach.

Background: The long-term impact and cost-effectiveness of weight management programs depend on posttreatment weight maintenance. There is growing evidence that interventions based on third-wave cognitive behavioral therapy, particularly acceptance and commitment therapy (ACT), could improve long-term weight management; however, these interventions are typically delivered face-to-face by psychologists, which limits the scalability of these types of intervention.

Objective: The aim of this study is to use an evidence-, theory-, and person-based approach to develop an ACT-based intervention for weight loss maintenance that uses digital technology and nonspecialist guidance to minimize the resources needed for delivery at scale.

Changing the narrative around obesity in the UK: a survey of people with obesity and healthcare professionals from the ACTION-IO study.

Objectives: To investigate the perceptions, attitudes, behaviours and potential barriers to effective obesity care in the UK using data collected from people with obesity (PwO) and healthcare professionals (HCPs) in the Awareness, Care, and Treatment In Obesity maNagement-International Observation (ACTION-IO) study.

Design: UK's PwO (body mass index of ≥30 kg/m based on self-reported height and weight) and HCPs who manage patients with obesity completed an online survey.

Results: In the UK, 1500 PwO and 306 HCPs completed the survey.

Patient motivation to lose weight: Importance of healthcare professional support, goals and self-efficacy.

Background: People with obesity (PwO) often struggle to achieve and maintain weight loss. This can perpetuate and/or be influenced by feelings of low motivation. This analysis from ACTION-IO data identified factors associated with PwO motivation to lose weight.

The 3Ds - Discussion, diagnosis and direction: Elements for effective obesity care by healthcare professionals.

Background: The care of people with obesity is often suboptimal due to both physician and patient perceptions about obesity itself and clinical barriers. Using data from the ACTION-IO study, we aimed to identify factors that might improve the quality of obesity care through adoption of the 3D approach (Discussion, Diagnosis and Direction [follow-up]) by healthcare professionals (HCPs).

Methods: An online survey was completed by HCPs in 11 countries.

Cognitive and behavioural strategies employed to overcome "lapses" and prevent "relapse" among weight-loss maintainers and regainers: A qualitative study.

While many behavioural weight management programmes are effective in the short-term, post-programme weight regain is common. Overcoming "lapses" and preventing "relapse" has been highlighted as important in weight-loss maintenance, but little is known on how this is achieved. This study aimed to compare the cognitive and behavioural strategies employed to overcome "lapses" and prevent "relapse" by people who had regained weight or maintained weight-loss after participating in a weight management programme.

British Obesity and Metabolic Surgery Society Guidelines on perioperative and postoperative biochemical monitoring and micronutrient replacement for patients undergoing bariatric surgery-2020 update.

Bariatric surgery is recognized as the most clinically and cost-effective treatment for people with severe and complex obesity. Many people presenting for surgery have pre-existing low vitamin and mineral concentrations. The incidence of these may increase after bariatric surgery as all procedures potentially cause clinically significant micronutrient deficiencies.

Clinical and cost-effectiveness of a diabetes education and behavioural weight management programme versus a diabetes education programme in adults with a recent diagnosis of type 2 diabetes: study protocol for the Glucose Lowering through Weight management (GLoW) randomised controlled trial.

Introduction: People with type 2 diabetes (T2D) can improve glycaemic control or even achieve remission through weight loss and reduce their use of medication and risk of cardiovascular disease. The Glucose Lowering through Weight management (GLoW) trial will evaluate whether a tailored diabetes education and behavioural weight management programme (DEW) is more effective and cost-effective than a diabetes education (DE) programme in helping people with overweight or obesity and a recent diagnosis of T2D to lower their blood glucose, lose weight and improve other markers of cardiovascular risk.

Methods And Analysis: This study is a pragmatic, randomised, single-blind, parallel group, two-arm, superiority trial.

Third-wave cognitive behaviour therapies for weight management: A systematic review and network meta-analysis.

This systematic review and network meta-analysis synthesized evidence on the effects of third-wave cognitive behaviour therapies (3wCBT) on body weight, and psychological and physical health outcomes in adults with overweight or obesity. Studies that included a 3wCBT for the purposes of weight management and measured weight or body mass index (BMI) pre-intervention and ≥ 3 months post-baseline were identified through database searches (MEDLINE, CINAHL, Embase, Cochrane database [CENTRAL], PsycINFO, AMED, ASSIA, and Web of Science). Thirty-seven studies were eligible; 21 were randomized controlled trials (RCT) and included in the network meta-analyses.

Third-wave cognitive behaviour therapies for weight management: systematic review and network meta-analysis protocol.

Introduction: Behavioural and cognitive behavioural programmes are commonly used to assist with weight management, but there is considerable scope to improve their effectiveness, particularly in the longer term. Third-wave cognitive behaviour therapies (CBTs) have this potential and are increasingly used. This systematic review will assess the effect of third-wave CBTs for weight management on weight, psychological and physical health outcomes in adults with overweight or obesity.

A systematic review of the physical activity assessment tools used in primary care.

Background: Primary care is an ideal setting for physical activity interventions to prevent and manage common long-term conditions. To identify those who can benefit from such interventions and to deliver tailored support, primary care professionals (e.g.

Guidelines for the follow-up of patients undergoing bariatric surgery.

Bariatric surgery can facilitate weight loss and improvement in medical comorbidities. It has a profound impact on nutrition, and patients need access to follow-up and aftercare. NICE CG189 Obesity emphasized the importance of a minimum of 2 years follow-up in the bariatric surgical service and recommended that following discharge from the surgical service, there should be annual monitoring as part of a shared care model of chronic disease management.

NICE-Accredited Commissioning Guidance for Weight Assessment and Management Clinics: a Model for a Specialist Multidisciplinary Team Approach for People with Severe Obesity.

Despite increasing prevalence of obesity, no country has successfully implemented comprehensive pathways to provide advice to all the severely obese patients that seek treatment. We aimed to formulate pathways for referral into and out of weight assessment and management clinics (WAMCs) that include internal medicine/primary care physicians as part of a multidisciplinary team that could provide specialist advice and interventions, including referral for bariatric surgery. Using a National Institute of Health and Care Excellence (NICE)-accredited process, a Guidance Development Group conducted a literature search identifying existing WAMCs.
