Usage and distribution for commercial purposes requires written permission., Background: Effective interventions and commercial programmes for weight loss (WL) are widely available, but most people regain weight. Few effective WL maintenance (WLM) solutions exist. The most promising evidence-based behaviour change techniques for WLM are self-monitoring, goal setting, action planning and control, building self-efficacy, and techniques that promote autonomous motivation (e.g., provide choice). Stress management and emotion regulation techniques show potential for prevention of relapse and weight regain. Digital technologies (including networked-wireless tracking technologies, online tools and smartphone apps, multimedia resources, and internet-based support) offer attractive tools for teaching and supporting long-term behaviour change techniques. However, many digital offerings for weight management tend not to include evidence-based content and the evidence base is still limited. The Project: First, the project examined why, when, and how many European citizens make WL and WLM attempts and how successful they are. Second, the project employed the most up-to-date behavioural science research to develop a digital toolkit for WLM based on 2 key conditions, i.e., self-management (self-regulation and motivation) of behaviour and self-management of emotional responses for WLM. Then, the NoHoW trial tested the efficacy of this digital toolkit in adults who achieved clinically significant (≥5%) WL in the previous 12 months (initial BMI ≥25). The primary outcome was change in weight (kg) at 12 months from baseline. Secondary outcomes included biological, psychological, and behavioural moderators and mediators of long-term energy balance (EB) behaviours, and user experience, acceptability, and cost-effectiveness. Impact: The project will directly feed results from studies on European consumer behaviour, design and evaluation of digital toolkits self-management of EB behaviours into development of new products and services for WLM and digital health. The project has developed a framework and digital architecture for interventions in the context of EB tracking and will generate results that will help inform the next generation of personalised interventions for effective self-management of weight and health., The NoHoW project has received funding from the European Union Horizon 2020 research and innovation programme under grant agreement No. 643309.

Objective Rates of adolescents with severe obesity continue to rise worldwide, with concurrent increases in metabolic and bariatric surgery (MBS) uptake. The gap between support (lifestyle, pharmacotherapy) interventions and MBS as treatment options for adolescents has been understudied. This review, couched in a socio-ecological framework, investigates how support interventions for adolescents with severe obesity could be combined or sequenced with MBS to optimize health outcomes. Methods A comprehensive search revealed 36 published articles between 1995 and 2019 that included the combination of support interventions and MBS among adolescents. Results There were no studies that specifically reported outcomes or effect sizes for the combination of lifestyle intervention with MBS. Previous studies have reported individual results for either lifestyle intervention or MBS but not for their compound effect. Conclusions As rates of adolescents with severe obesity are on the rise globally, future research should focus on how partnering support interventions with MBS can amplify positive short- and long-term health outcomes and within a socio-ecological framework. Understanding the sequence of these approaches will be of particular importance. High-risk and vulnerable populations such as ethnic minorities who have suffered a disproportionate burden of the obesity epidemic must be included in rigorously tested future trials of combination interventions to maximize health outcomes worldwide.

A decade after the first health app became available, the field of digital health has produced a range of health behavior insights and an expanding product portfolio. Despite sustained interest and growth fueled by academic and industry interests, the impact of digital health on health behavior change and related outcomes has been limited. This underperformance relative to expectations may be partially attributed to a gap between industry and academia in which both seek to develop technology-driven solutions but fail to converge around respective, unique strengths. An opportunity exists for new and improved collaborative models of research, innovation, and care delivery that disrupt the field of behavioral medicine and benefit academic and industry interests. For those partnerships to thrive, recognizing key differences between academic and industry roles may help smooth the path. Here we speak specifically to concerns particular to academics and offer suggestions for how to navigate related challenges.

Objective This randomized controlled trial was conducted to determine comparative efficacy of a 12-month community-centered weight management program (MEND2-5 for ages 2-5 or MEND/CATCH6-12 for ages 6-12) against a primary care-centered program (Next Steps) in low-income children. Methods Five hundred forty-nine Hispanic and black children (BMI ≥ 85th percentile), stratified by age groups (2-5, 6-8, and 9-12 years), were randomly assigned to MEND2-5 (27 contact hours)/MEND/CATCH6-12 (121.5 contact hours) or Next Steps (8 contact hours). Primary (BMI value at the 95th percentile [%BMIp95]) and secondary outcomes were measured at baseline, 3 months (Intensive Phase), and 12 months (Transition Phase). Results For age group 6-8, MEND/CATCH6-12 resulted in greater improvement in %BMIp95 than Next Steps during the Intensive Phase. Effect size (95% CI) was −1.94 (−3.88, −0.01) percentage points (P = 0.05). For age group 9-12, effect size was −1.38 (−2.87, 0.16) percentage points for %BMIp95 (P = 0.07). MEND2-5 did not differentially affect %BMIp95. Attendance averaged 52% and 22% during the Intensive and Transition Phases. Intervention compliance was inversely correlated to change in %BMIp95 during the Intensive Phase (P

Objective To date the application of eHealth strategies among adults and adolescents undergoing metabolic and bariatric surgery (MBS) has not been systematically reviewed. This study comprehensively examines eHealth intervention studies among MBS patients within the RE-AIM framework to assess reach, effectiveness, adoption, implementation and maintenance of these efforts. Methods A search was conducted using PubMed, EMBASE, CINAHL, PsycNET and SCOPUS of original research relating to eHealth strategies for MBS patients published in peer-reviewed journals and revealed 38 published articles between 2011 and 2019. Results Studies varied widely in terms of design (qualitative to randomized controlled trials) and eHealth delivery method (telemedicine to blog post content) with a balance of pre- or post-MBS use. No studies included adolescents and very few reported (1) a conceptual framework to support study design/outcomes; and (2) race/ethnicity composition. Conclusions Although some studies report that eHealth strategies/interventions are effective in producing post-MBS weight loss and other positive health outcomes, most are pilot studies or have study design limitations. There is an opportunity for development of (1) tailored eHealth interventions to support pre- and post-MBS sustained behavior change and improved outcomes; and (2) rigorous studies that employ robust conceptual frameworks so dissemination and implementation efforts can be mapped to construct-driven outcomes.

OBJECTIVES:Implementation of a large-scale, child weight management program in low-income, ethnically diverse communities provided an important opportunity to evaluate its effectiveness under service level conditions (i.e. provision as a primary care child weight management service). METHODS:MEND 7-13 is a community-based, multi-component, childhood obesity intervention designed to improve dietary, physical activity and sedentary behaviors. It comprises twice weekly sessions for 10 consecutive weeks (35 contact hours) and is delivered to groups of children and accompanying parents/caregivers. The evaluation used an uncontrolled, repeated measures design. Overall, 3782 children with overweight or obesity attended 415 MEND 7-13 programs in eight US states, of whom 2482 children (65.6%) had complete data for change in zBMI. The intervention targeted low-income, ethnically diverse families. Changes in anthropometric, cardiovascular fitness and psychological outcomes were evaluated. A longitudinal multivariate imputation model was used to impute missing data. Peer effects analysis was conducted using the instrumental variables approach and group fixed effects. RESULTS:Mean changes in BMI and zBMI at 10 weeks were -0.49 kg/m2 (95% CI: -0.67, -0.31) and -0.06 (95% CI: -0.08, -0.05), respectively. Benefits were observed for cardiovascular fitness and psychological outcomes. Mean peer reduction in zBMI was associated with a reduction in participant zBMI in the instrumental variables model (B = 0.78, P = 0.04, 95% CI: 0.03, 1.53). Mean program attendance and retention were 73.9% and 88.5%, respectively. CONCLUSION:Implementing MEND 7-13 under service level conditions was associated with short-term improvements in anthropometric, fitness and psychological indices in a large sample of low-income, ethnically diverse children with overweight and obesity. A peer effect was quantified showing that benefits for an individual child were enhanced, if peers in the same group also performed well. To our knowledge, this is the first US study to evaluate outcomes of an up-scaled community-based, child weight management program and to show positive peer effects associated with participation in the intervention.

To evaluate behavior modification of diet and parent feeding practices in childhood obesity interventions.Secondary analysis of randomized, controlled trial comparing Mind, Exercise, Nutrition … Do It! (MEND2-5 and MEND/Coordinated Approach to Child Health [CATCH6-12]) vs Next Steps at baseline and 3 and 12 months.Austin and Houston, TX.A total of 549 Hispanic and black children randomized to programs by age groups (2-5, 6-8, and 9-12 years) INTERVENTIONS: Twelve-month MEND2-5 and MEND/CATCH6-12 vs Next Steps.Diet (MEND-friendly/unfriendly food groups and Healthy Eating Index-2010) and parent feeding practices (parental overt control, discipline, limit setting, monitoring, reinforcement, modeling, and covert control; and food neophobia).Mixed-effects linear regression.Changes in diet quality, consumption of MEND-unfriendly foods, and parent feeding practices did not differ between programs. In both interventions, MEND-unfriendly vegetables, grains, dairy and protein, added fat and desserts/sugar-sweetened beverages declined in 2-5- and 6-8-year-olds (P.001). Healthy Eating Index-2010 improved in 2-5- (treatment; P = .002) and 6-8-year-olds (P = .001). Parental overt control decreased and limit setting, discipline, monitoring, reinforcement, and covert control increased with both interventions in 2-5- and 6-8-year-olds (P0.01-0.001).Diet quality, consumption of MEND-unfriendly foods, and parent feeding practices were altered constructively in 2 pediatric obesity interventions, especially in 2-5- and 6-8-year-olds.
