Abstract Background: The NIH-developed Diabetes Prevention Program (DPP) is successful in achieving clinically significant weight loss in individuals with overweight/obesity when delivered one-on-one. However, due to high cost of implementation, the long-term effectiveness remains limited. In response, a group-based version of the program, called the National DPP, was developed. The average weight loss following participation in this program was only about 3.5% with low long-term weight loss maintenance. Purpose: We aimed to optimize weight loss outcomes of the National DPP by integrating the habit formation tool of if-then plans into the program. Results at 3 and 12 months of participation showed no between-group differences between standard and enhanced DPP but higher weight loss in both groups compared to the National DPP. This paper reports the long-term weight loss maintenance data following participation in the program. Methods: Of the 172 participants enrolled at the beginning of the study, data from 110 participants was available and analyzed at 24 months, i.e. 12 months following the end of the 12-month intervention. Results: No between-group difference in weight loss maintenance was seen. Pooled results showed a significant weight regain from 12 to 24 months, i.e. an average of 7.85lbs of the 20.36lbs lost. However, participants from both groups were still 12lbs or 6.13% lighter at 24 months than at baseline. Conclusion: If-then plans did not result in a higher percentage of weight loss at 24-month follow-up. However, at 24 months, both groups maintained a significant portion of the weight lost at the end of intervention.

Abstract Background Current evidence suggests that some of the most effective weight loss approaches are changes in dietary and physical activity behaviors through lifestyle modification programs. The Group Lifestyle Balance (GLB) program is a group-based behavior modification program aimed at changing diet and physical activity for weight loss. It was developed to be more cost-effective and easier to disseminate than its individually administered parent program, the Diabetes Prevention Program (DPP). However, the average weight loss following participation in the GLB is only approximately 3.5%, with low long-term weight loss maintenance. Purpose We aimed to optimize the weight loss outcomes of the GLB to increase the efficacy already afforded by its cost-effectiveness and ease of dissemination. We did this by integrating the habit formation tool of if-then plans into the program. This program is called the enriched GLB or the McGill Comprehensive Health Improvement (CHIP) Healthy Weight Program. Results at 3 and 12 months of participation have already been published elsewhere. They showed no between-group differences between the standard and enriched GLB but higher weight loss in both groups compared to the DPP. This paper reports the long-term weight loss maintenance data following participation in the program. Methods Of the 172 participants enrolled at the beginning of the study, data from 110 participants were available and analyzed at 24 months, i.e., 12 months after the end of the 12-month intervention. Results No between-group difference in weight loss maintenance was observed. Pooled results showed a significant weight regain from 12 to 24 months, i.e., an average of 7.85 lbs. of the 20.36 lbs. lost. However, participants from both groups were still 12.51lbs or 6.13% lighter at 24 months than at baseline. Conclusion If-then plans did not result in a higher percentage of weight loss at 24-month follow-up compared to the standard GLB. However, at 24 months, both groups did show a maintenance of a significant portion of the weight lost at the end of intervention.

Frequent self-weighing is associated with weight loss maintenance. Several years ago, we investigated frequent self-weighing’s effect on weight loss and found the participants lost a significant amount of weight. Three years after this trial's end, participants were contacted for an update on their weight and self-weighing frequency. Weight change and self-weighing frequency since the end of the study were assessed. We hypothesized that participants who maintained frequent self-weighing behavior would have maintained their weight loss. Out of 98 participants enrolled in the RCT, 37% (n = 36) participated in this follow-up study. Total weight loss during the trial for the follow-up participants was 12.7 ± 19.4 lbs (p<0.001). Three years after intervention, participants regained 0.9 ± 4.34 lbs, a value that was not statistically different from zero (p=0.75). This did not differ by gender (p=0.655). Over 75% of these participants continued to weigh themselves at least once a week. Frequent self-weighing may be an effective, low-cost strategy for weight loss maintenance. Future research should further investigate the role of self-weighing in long-term weight gain prevention.

Background Rising levels of obesity require interventions that support people in long-term weight loss. The Football Fans in Training (FFIT) programme uses loyalty to football teams to engage men in weight loss. In 2011/12, a randomised controlled trial (RCT) found that the FFIT programme was effective in helping men lose weight up to 12 months. Objectives To investigate the long-term weight, and other physical, behavioural and psychological outcomes up to 3.5 years after the start of the RCT; the predictors, mediators and men’s qualitative experiences of long-term weight loss; cost-effectiveness; and the potential for long-term follow-up via men’s medical records. Design A mixed-methods, longitudinal cohort study. Setting Thirteen professional Scottish football clubs from the RCT and 16 additional Scottish football clubs that delivered the FFIT programme in 2015/16. Participants A total of 665 men who were aged 35–65 years at the RCT baseline measures and who consented to follow-up after the RCT (intervention group, n = 316; comparison group, n = 349), and 511 men who took part in the 2015/16 deliveries of the FFIT programme. Interventions None as part of this study. Main outcome measures Objectively measured weight change from the RCT baseline to 3.5 years. Results In total, 488 out of 665 men (73.4%) attended 3.5-year measurements. Participants in the FFIT follow-up intervention group sustained a mean weight loss from baseline of 2.90 kg [95% confidence interval (CI) 1.78 to 4.02 kg; p < 0.001], and 32.2% (75/233) weighed ≥ 5% less than at baseline. Participants in the FFIT follow-up comparison group (who participated in routine deliveries of the FFIT programme after the RCT) lost a mean of 2.71 kg (95% CI 1.65 to 3.77 kg; p < 0.001), and 31.8% (81/255) achieved ≥ 5% weight loss. Both groups showed long-term improvements in body mass index, waist circumference, percentage body fat, blood pressure, self-reported physical activity (PA) (including walking), the consumption of fatty and sugary foods, fruit and vegetables and alcohol, portion sizes, self-esteem, positive and negative affect, and physical and mental health-related quality of life (HRQoL). Mediators included self-reported PA (including walking) and sitting time, the consumption of fatty and sugary foods and fruit and vegetables, portion sizes, self-esteem, positive affect, physical HRQoL, self-monitoring of weight, autonomous regulation, internal locus of control, perceived competence, and relatedness to other FFIT programme participants and family members. In qualitative interviews, men described continuing to self-monitor weight and PA. Many felt that PA was important for weight control, and walking remained popular; most were still aware of portion sizes and tried to eat fewer snacks. The FFIT programme was associated with an incremental cost-effectiveness of £10,700–15,300 per quality-adjusted life-year (QALY) gained at 3.5 years, and around £2000 per QALY gained in the lifetime analysis. Medical record linkage provided rich information about the clinical health outcomes of the FFIT RCT participants, and 90% of men (459/511) who took part in the 2015/16 FFIT programme gave permission for future linkage. Conclusions Participation in the FFIT programme under both research (during the FFIT RCT) and routine (after the FFIT RCT) delivery conditions led to significant long-term weight loss. Further research should investigate (1) how to design programmes to improve long-term weight loss maintenance, (2) longer-term follow-up of FFIT RCT participants and (3) very long-term follow-up via medical record linkage.

Background: Obesity increases risk of diabetes, heart disease and cancer; a healthy weight reduces these risks, however weight loss efforts are prone to failure. Developing methods to promote weight loss maintenance is an important public health goal. We report on weight loss maintenance in individuals who followed a nutrient-dense, plant-rich (NDPR) diet. NDPR guidelines focus on increasing micronutrient density and avoidance of processed, highly palatable foods. Methods: Patients of a private family medical practice and members of a NDPR diet internet community (2273) completed an online survey providing information on length of time following a NDPR diet and body weight at several time points. Results: In respondents with pre-diet BMI ≥ 25 who had been following a NDPR diet for at least 2 years, those who reported adhering to NDPR guidelines in at least 80% of meals lost significantly more weight than those reporting lower adherence. Weight lost during year 1 was maintained at 2 and 3 years, and in respondents with initial BMI in the obese range (≥ 30), those losses were significantly greater in respondents who reported at least 80% adherence compared to 50-79% (56 lb. vs. 34 lb.) at 3 years. Between 1 year and 3 years, a low rate (19%) of weight regain ( ≥ 5 lb.) was reported among respondents 80-100% adherent to NDPR guidelines. Conclusions: Weight loss and maintenance for a period of 3 years was observed in this self-selected group, and respondents who reported 80-100% adherence lost significantly more weight than those who reported 50-79% adherence to NDPR guidelines. Individuals achieved substantially greater weight loss than that commonly observed in weight loss intervention studies. An intervention study, which would provide further insight into the influence of the NDPR guidelines on weight loss and maintenance, is warranted.

BACKGROUND Digital behavior change interventions (DBCIs) offer a promising channel for providing health promotion services. However, user experience of the technologies largely determines user engagement, which is necessary for their effectiveness. OBJECTIVE To evaluate user experiences with the NoHoW Toolkit (TK), a DBCI targeting weight loss maintenance (WLM), over a 12-month period using mixed methodology and to identify the main strengths and weaknesses of the TK as well as external factors affecting its adoption. Secondly, the objective was to describe objectively measured usage of the TK and its association with user experience. METHODS An 18-month, 2 x 2 factorial randomized controlled trial was delivered, including three intervention arms receiving an 18-week active intervention and a control arm. User experience of the TK was assessed quantitatively through electronic questionnaires after 1, 3, 6 and 12 months of use, including also thematically analyzed open-ended items. Focus group interviews were conducted at month 6 and thematically analyzed to gather deeper insight into user experience. Usage logs of the TK were used to evaluate the number of visits to the TK, the total duration spent in the TK, and intervention completion. RESULTS The level of usability of the TK was rated as satisfactory. User acceptance was rated as modest, declining during the trial in all arms, as did the objectively measured usage of the TK. The most appreciated features were weekly emails, graphs, goal setting, and interactive exercises. Four themes were identified in the qualitative data: 1) engagement with features, 2) usage decline, 3) external factors affecting the user experience, and 4) suggestions for improvements. CONCLUSIONS The long-term user experience of the TK highlighted the need to optimize the technical functioning, appearance and content of a DBCI before and during the trial, in a way a commercial app would. The users should be made aware of how they should use the intervention and what the use requires, especially in the case of more intensive intervention content.

Abstract Background Sex influences health and related behaviors due to biological and psychosocial/socioeconomic factors. Assessing sex-specific responses to integrated treatment for comorbid obesity and depression could inform intervention targeting. Purpose To test (a) whether sex moderates the effects of integrated collaborative care on weight and depression outcomes through 24 months and (b) whether treatment response at 6 months predicts 12 and 24 month outcomes by sex. Methods Secondary data analyses on weight and depression severity (SCL-20) measured over 24 months among 409 adults with obesity and depression in the Research Aimed at Improving Both Mood and Weight trial. Results Men achieved significantly greater weight reductions in intervention versus usual care than women, whereas women achieved significantly greater percentage reductions in SCL-20 than men at both 12 and 24 months. In logistic models, at 80% specificity for correctly identifying participants not achieving clinically significant long-term outcomes, women who lost &lt;3.0% weight and men who lost &lt;4.1% weight at 6 months had ≥84% probability of not meeting 5% weight loss at 24 months. Similarly, at 80% specificity, women who reduced SCL-20 by &lt;39.5% and men who reduced by &lt;53.0% at 6 months had ≥82% probability of not meeting 50% decrease in SCL-20 at 24 months. Conclusions Sex modified the integrated treatment effects for obesity and depression. Sex-specific responses at 6 months predicted clinically significant weight loss and depression outcomes through 24 months. Based on early responses, interventions may need to be tailored to address sex-specific barriers and facilitators to achieving healthy weight and depression outcomes at later time points.
