Peer Support Groups for Weight Loss

The patient experience in a virtual peer support group for patients with type 2 diabetes and obesity during the corona virus disease 19 pandemic: interview themes from a pilot study

BACKGROUND

Type 2 diabetes and obesity are lifelong conditions that require extensive lifestyle modifications. During the corona virus disease 19 (COVID-19) pandemic, in-person medical care was risky. Many patients suffered from isolation and loneliness. One remedy which would address both the need for obesity and diabetes-related self-management and social isolation is peer support groups. There is considerable evidence for the effectiveness of peer-led programs in weight management and in diabetes self-management. No prior study has evaluated the impact of a virtual peer support group for diabetes.

OBJECTIVES

To determine the feasibility and acceptability of a virtual peer support group for patients with type 2 diabetes and obesity [body mass index (BMI) > 30 kg/m2].

METHODS

Patients at an urban, Midwestern healthcare system enrolled in an 18-month remote (Zoom) (November 2021-May 2023) peer support group. Weekly meetings featured peer discussions on topics related to diabetes self-management. Semi-structured interviews post-intervention underwent independent thematic analysis by two coders until a set of common themes emerged.

RESULTS

All participants expressed satisfaction and enjoyment with the study. The opportunity to connect with peers, increase awareness of the importance of diabetes management behaviors, and learn new skills were cited as meaningful. Many participants lived alone, making the social support offered by the group especially valuable.

CONCLUSIONS

A long-term stand-alone virtual diabetes peer support group filled an important social and emotional need among its members, especially among those who were most isolated. To achieve long-term behavioral change and healthier outcomes, the support group may need to be paired with individual counseling.

A smartphone-based application to improve breastfeeding duration and self-efficacy: a randomized controlled clinical trial

A novel breastfeeding mobile app was created. We aim to determine if patients who utilize the app will have longer breastfeeding duration, improved breastfeeding self-efficacy scores at 1-year follow-up, and higher exclusive breastfeeding rates at 6 months postpartum. Participants were randomized, with 45 to the intervention and 48 to the control groups. Surveys were administered at 32-36-week gestation and 1 year postpartum. On average, women in the intervention group breastfed for 10.1 (SD ± 3.5) months compared to 8.9 (SD ± 4.1) months in the control group (p = .320). A Kaplan-Meier survival curve demonstrated a higher proportion of participants who breastfed for longer durations in the intervention group (p = .241). The change in self-efficacy was not statistically different in the two groups. The exclusive breastfeeding rate at 6 months postpartum is 81.3 percent in the intervention group and 60.0 percent in the control group (p = .277). While there is no statistical difference in breastfeeding outcomes, participant feedback suggests that features such as feeding-trackers, real-time lactation support, and moderated peer groups may enhance its impact. Future research should focus on refining these elements, recruiting larger samples, and minimizing loss-to-follow-up to fully assess the potential of mobile-based breastfeeding interventions.

Sex moderates diet quality differences in integrated collaborative care for comorbid obesity and depression: Post-hoc analysis of the RAINBOW RCT

OBJECTIVES

To investigate (1) whether an evidence-based behavioral weight loss intervention was associated with improved diet quality in adults with obesity and depression compared with usual care; and (2) whether the associations were modified by sex.

DESIGN

In the RAINBOW RCT, 409 participants were randomized in 1:1 ratio to receive a 12-month intervention integrating a Diabetes Prevention Program-based behavioral weight loss treatment with problem-solving therapy for depression (n = 204) or usual care (n = 205). Participants completed 24-h dietary recalls at baseline, 6, 12, 18, and 24 months. Dietary outcomes included the DASH score as the composite measure of diet quality and its components. Between-group differences in dietary outcomes were examined among all participants and by sex, using repeated-measures mixed-effects linear models.

RESULTS

Intervention group had mean age 50.9 (SD 12.2) years and 71% women, while control had 51.0 (11.9) years and 70% women. Changes in DASH scores did not differ between the intervention and usual care control groups through 24 months in both females and males. Compared with controls, males in the intervention group had decreased nut, seed, and legume intake at 6 (mean difference, -1.1; 95% CI, -1.9, -0.3 servings/day; P = 0.01; Pajd = 0.73) and 12 months (-1.0; -2.0, -0.0 servings/day; P = 0.048; Pajd = 0.73). Compared with controls, females in the intervention group had decreased fruit and vegetable intake at 18 (-1.8; -2.9, -0.6 servings/day; P = 0.002; Pajd = 0.08) and 24 months (-1.1; -2.2, -0.1 servings/day; P = 0.03; Pajd = 0.25), and whole grain intake at 24 months (-0.5; -0.9, -0.1 servings/day; P = 0.03; Pajd = 0.25), but increased percent calories from fat at 24 months (3.6; 0.6, 6.5; P = 0.02; Pajd = 0.25).

CONCLUSION

Diet quality not only did not improve in an effective behavioral weight loss intervention but deteriorated in females, in particular. These post-hoc findings warrant confirmation and may suggest sex-tailored behavior change techniques specifically targeting diet quality are needed in behavioral weight loss interventions aside from caloric reductions.

A qualitative study of the perceptions and experiences of participants and healthcare professionals in the DiRECT-Australia type 2 diabetes remission service

BACKGROUND

The UK Diabetes Remission Clinical Trial (DiRECT) study was replicated in an Australian primary care setting. This qualitative study aimed to explore and understand the perceptions and experiences of both participants and healthcare professionals (HCPs) involved in the DiRECT-Australia Type 2 Diabetes Remission Service.

METHODS

All participants and HCPs delivering the service were invited to participate in semi-structured interviews via online videoconferencing. The interview guides explored perceptions and experiences in DiRECT-Australia, covering aspects such as barriers and facilitators to recruitment and participation, motivations and challenges across service phases, adequacy of support provided and the overall acceptability of the service. All interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.

RESULTS

Eight DiRECT-Australia participants and six HCPs (three general practitioners, two practice nurses and one dietitian) participated. Four overarching themes were identified: (1) Enablers and barriers to recruitment and continuous participation in DiRECT-Australia; (2) Motivators and overcoming barriers across the total diet replacement, food reintroduction and weight maintenance phases; (3) Importance of participant-HCP interactions and continuous support; (4) Acceptance and long-term need for DiRECT-Australia. Adherence to total diet replacement was less challenging than anticipated by participants. Transitioning to the food reintroduction phase was difficult but overcome through HCP support. DiRECT-Australia was well accepted by both participants and HCPs, and participants expressed willingness to continue with the service, if provided on a long-term basis.

CONCLUSIONS

Both participants and HCPs were highly interested in the new diabetes remission service set up in an Australian primary care setting. The acceptability of DiRECT-Australia was underscored by participants emphasising the effectiveness of the service in achieving significant weight loss and diabetes remission. There is a need for long-term and wider implementation of the service to ensure that anyone with recent onset type 2 diabetes is offered the best possible chance to achieve remission.

Social Media for Nutrition Education-A Randomized Controlled Trial to Promote Fruit and Vegetable Intake in a University Setting: "The University of Valladolid Community Eats Healthy" Study

Social media- and internet-based interventions are nowadays widely used tools in health interventions. Although evidence of their effectiveness is still low, their applications could be very promising due to their affordability and wide reach. The current paper aims to evaluate the effectiveness of an intervention program, "The University of Valladolid Community Eats Healthy" (UVEH), to increase fruit and vegetable (FV) intake in adults from the University of Valladolid (U. Valladolid) employing three online methodologies. A sample of 211 volunteers was randomly assigned into four groups: virtual campus (VC), Facebook (FB), Instagram (IG), and control. An intervention based on the Theory of Planned Behavior was implemented for seven weeks. Data were collected at the beginning (T0) and the end of the program (T1). The Predimed questionnaire was employed to assess FV intake. Vegetable intake was statistically significantly higher in the VC group (17.4% pre vs. 72.7% post). In the rest of the groups, there was also an increase in intake. Fruit consumption increased slightly only in the VC group (23.9% pre vs. 45.5% post). Participation decreased through the weeks: FB (week 2), IG (week 3), and VC (week 4). Retention was higher in the VC (48%) and control (60%) groups. Internet-based interventions employing interactive platforms such as virtual campus can be effective in enhancing participants' dietary habits in a clinically relevant manner.

Development and Feasibility of an eHealth Diabetes Prevention Program Adapted for Older Adults-Results from a Randomized Control Pilot Study

Lifestyle programs that reduce health risks and support weight loss (WL) in older adults face adherence and attendance challenges due to reduced energy requirements, impaired mobility, lack of transportation, and low social support. Tailored lifestyle and weight management programs are needed to better support healthy aging for older adults. Here, we developed and piloted an age-adapted, remotely delivered modification of the Diabetes Prevention Program (DPP). The modification includes age-appropriate goals, visuals, and examples; flexible dietary composition; remote classroom and fitness-monitoring technology; and standardized online classroom materials employing pedagogical and behavior change theory. The modifications were designed to safeguard fidelity and to boost adherence, engagement, and knowledge integration, with the convenience of a fully remote WL program for diverse older adults. Six-month pilot data are presented from older adults (55-85 years, body mass index (BMI) 27-39.9 kg/m2, N = 20) randomly allocated to an online DPP intervention with weight, diet, and activity monitored remotely, or into a waitlisted control. The intervention achieved 100% attendance and adherence to self-monitoring. The intervention group mean (±SD) body weight change was -9.5% (±4.1); 90% lost ≥ 5%. By contrast, the control group gained 2.4% (±1.8). Once thought incompatible with older adults, remote interventions are feasible for older adults and can support fidelity, adherence, engagement, and clinically significant WL. Standardized materials are provided for future implementation.

Peer-led lifestyle interventions for the primary prevention of cardiovascular disease in community: a systematic review of randomised controlled trials

BACKGROUND

Peer-led lifestyle interventions have gained recognition as effective approaches for managing and preventing chronic diseases. However, there remains a critical knowledge gap regarding the impact and effectiveness of peer-led interventions specifically in the primary prevention of cardiovascular disease (CVD). Our systematic review aims to synthesise the available evidence and evaluate the impact of peer-led lifestyle interventions, providing invaluable insights that can guide the development of peer-led strategies for preventing CVD.

METHODS

Systematic database searches were conducted on Ovid Medline, Embase, Cochrane Centre for Controlled Trials, PubMed and Scopus to source peer-reviewed articles published between 2013 and 2023. Reference lists of the included publications were also manually searched.

RESULTS

Fourteen unique randomised controlled trials were identified, of which three were pilot studies. Most of the interventions were conducted among individuals at moderate to high risk of CVD and lasted for a year. There is a variety of components in intervention delivery, including group discussions and individual counselling. Peer leader training mostly covered intervention delivery, communication, and research-specific skills. Systolic blood pressure showed the most promising CVD-related improvement, while mixed results were found for several other dietary and lifestyle behavioural outcomes.

CONCLUSION

Peer-led lifestyle interventions have shown varying effectiveness in cardiovascular health outcomes. The competencies and roles of peer leaders were identified to guide future intervention development with a more comprehensive approach to the primary prevention of CVD.

Practical Lifestyle Management of Nonalcoholic Fatty Liver Disease for Busy Clinicians

Weight loss achieved through a combination of healthy eating patterns that encompass the principles of the Mediterranean diet and regular physical activity is the most evidence-based treatment for nonalcoholic fatty liver disease. Although other types of diets have demonstrated efficacy in liver fat reduction, the Mediterranean diet confers additional cardiometabolic benefits. Macronutrient composition, food choices, and timing of eating can be tailored to individual preferences, culture, and financial circumstances; however, recommended healthy eating patterns are characterized by minimally processed or unprocessed foods (vegetables, legumes, nuts and seeds, fruits, whole grains, and unprocessed meats and fish) that are low in sugar, refined carbohydrates, and saturated fat and high in fiber, polyphenols, vitamins, minerals, and healthy fats. Physical activity can independently improve steatosis, prevent fibrosis and cirrhosis, and reduce mortality.

Social media-based interventions for adults with obesity and overweight: a meta-analysis and meta-regression

Social isolation and loneliness are growing public health concerns in adults with obesity and overweight. Social media-based interventions may be a promising approach. This systematic review aims to (1) evaluate the effectiveness of social media-based interventions on weight, body mass index, waist circumference, fat, energy intake and physical activity among adults with obesity and overweight and (2) explore potential covariates on treatment effect. Eight databases, namely, PubMed, Cochrane Library, Embase, CINAHL, Web of Science, Scopus PsycINFO and ProQuest, were searched from inception until December 31, 2021. The Cochrane Collaboration Risk of Bias Tool and Grading of Recommendations, Assessment, Development and Evaluation criteria evaluated the evidence quality. Twenty-eight randomised controlled trials were identified. Meta-analyses found that social media-based interventions had small-to-medium significant effects on weight, BMI, waist circumference, body fat mass and daily steps. Subgroup analysis found greater effect in interventions without published protocol or not registered in trial registries than their counterparts. Meta-regression analysis showed that duration of intervention was a significant covariate. The certainty of evidence quality of all outcomes was very low or low. Social media-based interventions can be considered an adjunct intervention for weight management. Future trials with large sample sizes and follow-up assessment are needed.

Evaluation of dietary habits and cooking confidence using virtual teaching kitchens for perimenopausal women

BACKGROUND

The transition to menopause is a time when women are at increased risk for chronic and cardiovascular diseases, and weight gain. This study evaluates the efficacy of virtual teaching kitchen (TK) interventions on cooking confidence and consumption of a healthy diet in women over 45.

METHODS

This teaching kitchen intervention is a synchronous online series of classes for perimenopausal women, with 45 min of live cooking and 15 min of nutrition discussion. From September 2020 through January 2022, participants completed online pre- post-intervention surveys addressing weight, eating habits, cooking confidence and self-efficacy. Analysis used paired samples t-test and Wilcoxon signed rank sum test for normally and non-normal distributed data respectively.

RESULTS

Of the 609 unique participants, 269 women completed both pre and post surveys after attending classes. Participants self-reported a statistically significant decreased weight (p < 0.001), increased daily consumption of fruit/vegetables (p < 0.039), fish (p < 0.001) and beans (p < 0.005), and decreased daily consumption of red meat (p < 0.001), sugary beverages (p < 0.029) and white grains (p < 0.039). There was significant improvement in cooking self-efficacy and confidence.

CONCLUSIONS

Virtual teaching kitchens were effective in improving culinary and dietary habits among peri- and post-menopausal women. This early evidence suggests that teaching kitchens can effectively reach larger populations for healthy behavioral modification.

Randomised controlled trial of breast cancer and multiple disease prevention weight loss programmes vs written advice amongst women attending a breast cancer family history clinic

BACKGROUND

Overweight and obesity are common amongst women attending breast cancer Family History, Risk and Prevention Clinics (FHRPCs). Overweight increases risk of breast cancer (BC) and conditions including¹ cardiovascular disease (CVD) and type-2 diabetes (T2D). Clinics provide written health behaviour advice with is likely to have minimal effects. We assessed efficacy of two remotely delivered weight loss programmes vs. written advice.

METHOD

210 women with overweight or obesity attending three UK FHRPCs were randomised to either a BC prevention programme (BCPP) framed to reduce risk of BC (n = 86), a multiple disease prevention programme (MDPP) framed to reduce risk of BC, CVD and T2D (n = 87), or written advice (n = 37). Change in weight and health behaviours were assessed at 12-months.

RESULTS

Weight loss at 12 months was -6.3% (-8.2, -4.5) in BCPP, -6.0% (-7.9, -4.2) in MDPP and -3.3% (-6.2, -0.5) in the written group (p = 0.451 across groups). The percentage losing ≥10% weight in these groups were respectively 34%, 23% and 14% (p = 0.038 across groups).

DISCUSSION

BCPP and MDPP programmes resulted in more women achieving ≥10% weight loss, but no evidence of additional benefits of MDPP. A multicentre RCT to test the BCPP across UK FHRPCs is warranted. Clinical Trial Registration ISRCTN16431108.

Insights Into Patients' Perceptions of Health-Related Social Needs and the Role of the Adult Primary Care Clinic

INTRODUCTION/OBJECTIVES

While it is well established that unmet healthrelated social needs (HRSN) adversely affect health outcomes, there has been limited evaluation in adult primary care of patients' perceptions of how these needs impact their health and the role of the primary care provider (PCP). The objective of this study is to identify patients' perceptions of HRSN and how PCPs could help address them. Secondary objectives include exploring the impact of goal setting and a 1-time cash transfer (CT).

METHODS

This qualitative study used semi-structured baseline and follow-up interviews with patients in internal medicine clinics. Adult primary care patients were included if they screened positive as having 1 of 3 HRSN: financial resource strain, transportation needs, or food insecurity. All participants completed an initial interview about their HRSN and health, and were asked to set a 6-month health goal. At enrollment, participants were randomized to receive a $500 CT or a $50 participation reward. At 6-months, patients were interviewed again to investigate progress toward meeting their health goals, [when applicable] how the CT helped, and their beliefs about the role of PCPs in addressing HRSN.

RESULTS

We completed 30 initial and 25 follow-up interviews. Participants identified their HRSN, however most did not readily connect identified needs to health. Although participants were receptive to HRSN screening, they did not feel it was their PCP's responsibility to address these needs. Verbal goal-setting appeared to be a useful tool, and while the CTs were appreciated, patients often found them inadequate to address HRSN.

CONCLUSIONS

Given the importance of identifying the social conditions that shape patients' health, providers, and health systems have an opportunity to re-evaluate their role in helping patients address these barriers. Future studies could examine the effect of more frequent disbursement of CTs over time.

Psychosocial Aspects of Metabolic and Bariatric Surgeries and Endoscopic Therapies

Obesity is a prevalent progressive and relapsing disease for which there are several levels of intervention, including metabolic and bariatric surgery (MBS) and now endoscopic bariatric and metabolic therapies (EBMTs). Preoperative psychological assessment focused on cognitive status, psychiatric symptoms, eating disorders, social support, and substance use is useful in optimizing patient outcomes and minimizing risks in MBS. Very little is known about the psychosocial needs of patients seeking EBMTs, though these investigations will be forthcoming if these therapies become more widespread. As MBS and EBMT inherently alter the gastrointestinal (GI) tract, considerations for the longer-term GI functioning of the patient are relevant and should be considered and monitored.

Nutrition and Exercise for Wellness and Recovery: A Randomized Controlled Trial of a Community-Based Health Intervention

OBJECTIVE

The purpose of this study was to examine the efficacy of the Nutrition and Exercise for Wellness and Recovery (NEW-R) intervention for improving competency and behaviors related to diet, physical activity, and weight management.

METHODS

Participants with psychiatric disabilities were recruited from four community mental health agencies and a hospital-based psychiatric outpatient clinic and randomly assigned to the NEW-R intervention (N=55) or control condition (N=58). Outcome measures included the Perceived Competence Scale, Health-Promoting Lifestyle Profile (HPLP), and weight change; random-effects regression models were used. A follow-up analysis examined the interactions of group, time, and site.

RESULTS

Fifty of the 55 intervention participants and 57 of the 58 control participants completed the study. The two groups did not differ significantly on any measured baseline characteristic. The intervention group had statistically significant improvements, compared with the control group, in perceived competence for exercise and healthy eating, total HPLP score, and scores on two HPLP subscales (nutrition and spiritual growth). No significant difference between groups was found for weight loss. A study condition × time × site effect was observed: at the three sites where mean weight loss occurred, NEW-R participants lost significantly more weight than did control participants.

CONCLUSIONS

NEW-R offers promise as an intervention that can initiate the change to healthy lifestyle behaviors and boost perceived competence in a healthy lifestyle. It may also be effective for weight loss when administered in supportive settings.

Discovering Engagement Personas in a Digital Diabetes Prevention Program

Digital health technologies are shaping the future of preventive health care. We present a quantitative approach for discovering and characterizing engagement personas: longitudinal engagement patterns in a fully digital diabetes prevention program. We used a two-step approach to discovering engagement personas among n = 1613 users: (1) A univariate clustering method using two unsupervised k-means clustering algorithms on app- and program-feature use separately and (2) A bivariate clustering method that involved comparing cluster labels for each member across app- and program-feature univariate clusters. The univariate analyses revealed five app-feature clusters and four program-feature clusters. The bivariate analysis revealed five unique combinations of these clusters, called engagement personas, which represented 76% of users. These engagement personas differed in both member demographics and weight loss. Exploring engagement personas is beneficial to inform strategies for personalizing the program experience and optimizing engagement in a variety of digital health interventions.

Mobile health assisted self-monitoring is acceptable for supporting weight loss in rural men: a pragmatic randomized controlled feasibility trial

BACKGROUND

Addressing overweight and obesity among men at-risk for obesity-related diseases and disability in rural communities is a public health issue. Commercial smartphone applications (apps) that promote self-monitoring for weight loss are widely available. Evidence is lacking regarding what support is required to enhance user engagement with and effectiveness of those technologies. Pragmatically comparing these apps effectiveness, including rural men's desired forms of support when using them, can lead to greater weight loss intervention impact and reach. This study assessed the feasibility and acceptability of a mobile technology application applied differently across two groups for weight loss.

METHODS

In a two-armed, pragmatic pilot feasibility study, 80 overweight and obese men aged 40-69 were randomized using a 1:1 ratio to either an enhanced Mobile Technology Plus (MT+) intervention or a basic Mobile Technology (MT) intervention. The MT+ group had an enhanced smartphone app for self-monitoring (text messaging, discussion group, Wi-Fi scale) whereas the MT group received a basic app that allowed self-monitoring logging only. Assessments were collected at baseline, 3 and 6 months. App logs were analyzed to track engagement and adherence to self-monitoring. Acceptability was assessed via focus groups. Analysis included descriptive statistics and qualitative content analysis.

RESULTS

Of 80 men recruited, forty were allocated to each arm. All were included in the primary analysis. Recruitment ended after 10 months with a 97.5 and 92.5% (3 month, 6 month) retention rate. Over 90% of men reported via survey and focus groups that Lose-It app and smart scale (MT+) was an acceptable way to self-monitor weight, dietary intake and physical activity. Adherence to daily app self-monitoring of at least 800 dietary calories or more (reported respectively as MT+, MT) was positive with 73.4, 51.6% tracking at least 5 days a week. Adherence to tracking activity via recorded steps four or more days weekly was positive, 87.8, 64.6%. Men also adhered to self-weighing at least once weekly, 64, 46.3%. At 6 months, an observed mean weight loss was 7.03 kg (95% CI: 3.67, 10.39) for MT+ group and 4.14 kg (95% CI: 2.22, 6.06) for MT group, with 42.9 and 34.2% meeting ≥5% weight loss, respectively. No adverse events were reported.

CONCLUSIONS

This National Institutes of Health-funded pilot study using mobile technologies to support behavior change for weight loss was found to be feasible and acceptable among midlife and older rural men. The interventions demonstrated successful reductions in weight, noting differing adherence to lifestyle behaviors of eating, monitoring and activity between groups, with men in the MT+ having more favorable results. These findings will be used to inform the design of a larger scale, clinical trial.

TRIAL REGISTRATION

The trial was prospectively registered with ClinicalTrials NCT03329079 . 11/1/2017.

Digital Lifestyle Medicine: Designing, Delivering, and Scaling for Impact

Digital Lifestyle Medicine (DLM) is a consumer-centric model of care which elevates the importance of daily behaviors in preventing and reversing chronic disease using virtual and digital modalities to reach patients in the context where lifestyle behaviors occur and empower them to stay well. DLM is health care reimagined, designed to inspire patients to live their best life by enabling skill-building, self-efficacy, and sustainable behavior change supported by peers, scientific-evidence, and a multidisciplinary team of lifestyle medicine (LM) clinicians. Importantly, it requires insights and collaboration from healthcare experts and technology entrepreneurs to provide a profoundly different "user experience" layered with context, relevance, and scalability. Using examples from our DLM practice, we describe how key components of LM practice, including a multidisciplinary care team, behavior change support, health coaching, and peer support, are prime for digital delivery. We conclude by providing preliminary patient outcomes to date, key success factors, and opportunities for enhancement and expansion to inform the adoption and successful implementation of DLM across the collective of LM practice.

A Review of Telemedicine Interventions for Weight Loss

Purpose of Review

Telemedicine has become popular as an alternative for in-person weight loss treatment during the COVID-19 pandemic. This review focuses on weight loss interventions utilizing real-time telemedicine.

Recent Findings

Telemedicine interventions are usually run as a weekly counseling and educational session or as a complement to a primarily Web-based intervention. A wide variety of healthcare professionals may provide the intervention. Common content includes portion control, increased physical activity, and relapse prevention. Self-monitoring is associated with intervention success. Modalities considered include online chats, text messages, phone calls, and videoconferences. Videoconferencing may be especially useful in capturing the interpersonal connection associated with in-person care but is understudied compared to other modalities. While many interventions show improvements in weight and weight-related outcomes, small sample sizes limit generalizability. Technology access and digital literacy are both necessary.

Summary

Telemedicine interventions can successfully help patients with obesity lose weight. Telemedicine interventions provide a safe, remote alternative and may expand treatment access to hard-to-reach populations. Further research is needed on telemedicine weight loss treatments for seniors, men, and ethnic minorities, as well as on the impact of long-term interventions.

Group versus one-to-one multi-component lifestyle interventions for weight management: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Multi-component lifestyle interventions that incorporate diet, physical activity and behaviour change are effective for weight management. However, it is not clear whether delivery in a group or one-to-one format influences weight loss efficacy. The present study aimed to systematically review the evidence of the effectiveness of group compared to one-to-one multi-component lifestyle interventions for weight management.

METHODS

MEDLINE, EMBASE, CINAHL, CENTRAL and ISRCTN databases were searched from inception up to February 2020 for randomised controlled trials comparing group versus one-to-one multi-component lifestyle interventions for weight loss in adults with a body mass index ≥ 25 kg m^-2 . The primary outcome was weight loss (kg) at 12 months and the secondary outcome was attainment of ≥5% weight loss at 12 months. Risk of bias was assessed using the Cochrane Risk of Bias Tool. Meta-analysis used random effects and estimated risk ratios and continuous inverse variance methods. Heterogeneity was investigated using I² statistics and sensitivity analyses.

RESULTS

Seven randomised controlled trials with 2576 participants were included. Group interventions were favoured over one-to-one interventions for weight loss at 12 months (-1.9 kg, 95% confidence interval = -1.3 to -2.6; I²  = 99%). Participants of group interventions were more likely to attain ≥5% weight loss at 12 months relative to one-to-one interventions (relative risk = 1.58, 95% confidence interval = 1.25-2.00; I²  = 60%).

CONCLUSIONS

Group multi-component lifestyle interventions are superior for weight loss compared to one-to-one interventions with respect to adult weight management. Further research is required to determine whether specific components of group interventions can explain the superiority of weight loss outcomes in group interventions.

Creating Healthy Change in the Preconception Period for Women with Overweight or Obesity: A Qualitative Study Using the Information-Motivation-Behavioural Skills Model

Worldwide, half of women begin a pregnancy with overweight or obesity, which increases the risk of pregnancy and birth complications and adversely affects the lifelong health of the offspring. In order for metabolic changes to influence the gestational environment, research suggests that weight loss should take place before conception. This study aimed to understand women’s emotional and social contexts, knowledge, motivations, skills and self-efficacy in making healthy change. Semi-structured interviews conducted with twenty-three women with overweight or obesity, informed by the Information–Motivation–Behavioural Skills (IMB) model, were analysed using reflexive thematic analysis. Information-related themes identified included poor health risk knowledge, healthy food decisions and health versus convenience. The Motivation themes comprised taking responsibility, flexible options, social expectations, interpersonal challenges and accountability. Behavioural Skills entailed themes such as the mental battle, time management, self-care and inspiration. An environmental factor was identified in affordability—limiting access to healthier alternatives. Women wanted simple, flexible options that considered family commitments, time and budgetary constraints. Unprompted, several mentioned the importance of psychological support in managing setbacks, stress and maintaining motivation. Strategies for enhancing self-efficacy and motivational support are required to enable longstanding health behaviour change. Findings will inform intervention mapping development of an eHealth solution for women preconception.
