“…Contrary to what has been observed in adults, 18, 24 we did not observe statistically significant associations of physical activity levels or sitting-time with weight-loss maintenance despite there being potentially meaningful mean differences between groups. The majority of participants, similar to adults, 25 were highly inactive and sedentary, regardless of group assignment.…”

“…Additionally, several post-operative behavioral factors have been shown to influence weight-loss outcomes. These factors include adherence to food intake guidelines such portion size, 16, 17 physical activity and inactivity, 18 and self-weighing. 17 Whether these post-operative factors influence weight-loss maintenance in the post-bariatric surgery setting among adolescents has yet to be examined.…”

Factors associated with long-term weight-loss maintenance following bariatric surgery in adolescents with severe obesity

Background/Objectives Bariatric surgery produces robust weight-loss, however, factors associated with long-term weight-loss maintenance among adolescents undergoing Roux-en-Y gastric bypass surgery (RYGB) are unknown. Subjects/Methods Fifty adolescents (mean±SD age and BMI = 17.1±1.7yrs and 59±11kg/m2) underwent RYGB, had follow-up visits at 1-yr and at a visit between 5–12yrs following surgery (FABS-5+ visit; mean±SD 8.1±1.6yrs). A non-surgical comparison group (n=30; mean±SD age and BMI = 15.3±1.7yrs and BMI=52±8kg/m2) was recruited to compare weight trajectories over-time. Questionnaires (health-related and eating behaviors, health responsibility, impact of weight on quality of life, international physical activity questionnaire (IPAQ), and dietary habits via surgery guidelines) were administered at the FABS-5+ visit. Post-hoc, participants were split into 2 groups: long-term weight loss maintainers (n=23; baseline BMI=58.2kg/m2; 1-yr BMI=35.8kg/m2; FABS-5+ BMI=34.9kg/m2) and re-gainers (n=27; baseline BMI=59.8kg/m2; 1-yr BMI=36.8 kg/m2; FABS-5+ BMI=48.0kg/m2) to compare factors which might contribute to differences. Data were analyzed using generalized estimating equations adjusted for age, sex, baseline BMI, baseline diabetes status, and length of follow-up. Results The BMI of the surgical group declined from baseline to 1-yr (−38.5±6.9%), which, despite some regain, was largely maintained until FABS-5+ (−29.6±13.9 % change). The BMI of the comparison group increased from baseline to the FABS-5+ visit (+10.3±20.6%). When the surgical group was split into maintainers and re-gainers, no differences in weight-related and eating behaviors, health responsibility, physical activity/inactivity, or dietary habits were observed between groups. However, at FABS-5+, maintainers had greater overall QOL scores than re-gainers (87.5±10.5 vs. 65.4±20.2, p<0.001) and in each QOL sub-domain (p<0.01 all). Conclusions Long-term weight outcomes for those who underwent weight loss surgery were superior to those who did not undergo surgical treatment. While no behavioral factors were identified as predictors of success in long-term weight-loss maintenance, greater QOL was strongly associated with maintenance of weight loss among adolescents who underwent RYGB surgery.

“…Intervention staff also encouraged participants in this arm to engage in specific behavioral strategies associated with long-term weight control including breakfast eating, reducing sedentary time, and developing a consistent eating and activity routine. [26–28] In addition to this one-time group session, all Standard participants received monthly informational emails from a research assistant that included problem solving strategies to promote physical activity and reduce caloric intake plus access to healthy, low calorie recipes.…”

Weight loss maintenance is a significant challenge in obesity treatment. During maintenance the “costs” of adhering to weight management behaviors may outweigh the “benefits.” This study examined the efficacy of a novel approach to weight loss maintenance based on modifying the cost-benefit ratio. Individuals who achieved a 5% weight loss (N=75) were randomized to one of three, 10-month maintenance interventions. All interventions were delivered primarily via the Internet. The Standard arm received traditional weight maintenance strategies. To increase benefits, or rewards, for maintenance behaviors, the two cost-benefit intervention conditions received weekly monetary rewards for self-monitoring and social reinforcement via e-coaching. To decrease behavioral costs (boredom) and increase novelty, participants in the cost-benefit conditions also monitored different evidence-based behaviors every two weeks (e.g., Weeks 1 & 2: steps; Week 3 & 4: red foods). The primary difference between the cost-benefit interventions was type of e-coach providing social reinforcement: Professional (CB Pro) or Peer (CB Peer). Study procedures took place in Providence, RI from 2013–2014. Retention was 99%. There were significant group differences in weight regain (p=.01). The Standard arm gained 3.5±5.7kg. In contrast, participants in CB Pro and CB Peer lost an additional 1.8±7.0kg and 0.5±6.4kg, respectively. These results suggest that an Internet delivered cost-benefit approach to weight loss maintenance may be effective for long-term weight control. In addition, using peer coaches to provide reinforcement may be a particularly economic alternative to professionals. These data are promising and provide support for a larger, longer trial.

“…Vatier et al () found that decreases in reported television (TV) watching from pre‐op to 1‐year post‐RYGB were inversely associated with changes in fat mass, independently of PA. In another study, self‐reported sitting time was inversely associated, independently of MVPA, with total weight loss and weight loss maintained in patients 2–16 years post‐RYGB (Herman et al, ). Only one study to date has examined the relationship between objectively measured SB and bariatric surgery outcomes, showing a positive association between SB time and current weight in patients 6–18 months post‐op (Chapman et al ., ).…”

Physical activity (PA) and sedentary behaviors (SB—i.e. activities involving low energy expenditure and a sitting/reclining posture) may each have significant implications for weight loss and other bariatric surgery outcomes. While early studies suggested that patients typically comply with clinical recommendations to adopt habitual PA, these data were based on retrospective questionnaires. Conversely, recent studies incorporating mobile health (mHealth) technologies (e.g., objective monitors), which assess PA and SB in real-time and in the natural environment, show that most patients are inactive and highly sedentary preoperatively, and only make modest changes in these behaviors postoperatively. In addition to using mHealth technologies for obtaining accurate and detailed information on PA and SB, they are increasingly being employed to intervene on patients’ PA and SB and/or evaluate intervention outcomes. Researchers and clinicians are encouraged to consider the benefits of using mHealth technology when studying and treating PA and SB in bariatric surgery patients.
