Abstract Bariatric surgery is the most effective treatment for severe obesity (body mass index >40), helping individuals lose, on average, 25%–29% of their body weight over the first year. However, many patients begin to plateau and regain weight within 12–24 months, and 20% of patients begin to regain weight within 6 months postsurgery. As physical activity (PA) is an important predictor of weight loss and maintenance postsurgery, there is a need for scalable, effective lifestyle interventions to help bariatric patients increase PA in order to maximize their weight loss and maintenance. To assess feasibility of using mobile health (mHealth) tools to support PA postsurgery, we conducted a quality-improvement optimization pilot of BariFit, an mHealth intervention that combines commercial devices and custom text messages. Fifty-one bariatric patients enrolled in a 16-week optimization pilot of BariFit. To assess feasibility, pre–post changes in PA were assessed using activPAL. In addition, the pilot randomized, using a 2 × 2 factorial design, two adaptive approaches to daily step goals (variable and 60th percentile goals) and provision of rest days (yes/no), and microrandomized provision of SMS-delivered activity suggestions five times a day for each participant. Adherence to using study equipment was over 95% at 16 weeks. Participants increased PA by 1,866 steps from baseline to end-of-study (p < .007). Participants who received variable step goals averaged 1,141 more steps per day (p = .096) than those who received 60th percentile goals. Activity suggestions had no effect. mHealth interventions are feasible for supporting PA postbariatric surgery.

Abstract Background Bariatric surgery is the most effective treatment for obesity. During long-term follow-up, weight loss (WL) is variable between subjects. The aim of this study is to assess the change in percentage of total weight loss (%TWL) and excess weight loss (%EWL) and to describe the factors associated with greater or lesser WL over time. Methods Longitudinal study including patients treated with laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (LSG) and followed at Hospital Universitario San Ignacio, Bogotá (Colombia). Baseline data was recorded before surgery. Follow-up was performed at 3 (n=192), 6 (n=190), 9 (n=188), 12 (n=186), 24 (n=99) and 36 (n=30) months. Generalized Estimating Equation (GEE) analysis was used to assess the change in %TWL and %EWL over time. Results 196 patients were included (82.4% female, BMI 41.3±5.2 kg/m2). The tendency to increase on %TWL (31.6±6.6) and %EWL (80.2 RIQ 70.7-97.3) was evident in the first year, stabilizing after that. Nutritionist follow-up, baseline BMI>40 kg/m2 and WL≥10kg before surgery were associated with an average higher increase of %TWL (2.39% p=0.014, 0.41% p<0.001 and 0.37% p=0.003, respectively). Subjects who performed physical activity >30 minutes/day after surgery reduced %TWL in 0.74% (p=0.009). Similar findings were described on %EWL. Conclusion Follow-up during the first year after bariatric surgery is critical to achieving %TWL and %EWL goals. This study suggests that modifiable factors such as nutritional follow-up, WL before surgery and time of physical activity are associated with a significant change in %TWL and %EWL during follow-up by a multidisciplinary team.

Background In clinical practice, it is difficult to convey the benefits of sustained physical activity to adult patients with excess weight or obesity. For this purpose, a goal-setting walking prescription may be an effective strategy. Objective This study aimed to determine the efficacy of the intervention of a pedometer app in setting a goal to reach 10,000 steps per day in adults. Methods Overweight adults (n=98; mean body mass index 32.53 [SD 4.92] kg/m2) were randomized to one of two conditions (control or intervention). Both groups downloaded a pedometer app that recorded their daily step counts and were given a daily walking goal of 10,000 steps. Subjects participated in a 24-week in-person behavioral weight control program and were asked to monitor their daily levels using the pedometer app. Baseline data were recorded and followed up weekly. Only the intervention group had structured information delivery, a personalized physical activity prescription, and follow-up on number of steps per day. Results The results show that regardless of sex or age, prescribing walking increased the number of steps per day by 4806 step on average (standardized β coefficient=–0.813, SE=427.586, t=–11.242, P<.001). Conclusions These results could have implications for improving self-monitoring in overweight adults during periods of weight loss. Health professionals should analyze the implementation of tools that permit them to prescribe, follow up, and encourage the achievement of a goal of physical activity in overweight or obese patients.

Purpose. Obesity has reached epidemic proportions in the U.S. and has nearly doubled worldwide since 1980. Bariatric surgery is on the rise, but little focus has been placed on the psychosocial impacts of surgery. The purpose of this study was to explore experiences of patients who have undergone bariatric surgery at least two years before to gain an understanding of the successes and challenges they have faced since surgery. Methods. This study used a phenomenological approach, to investigate the meaning and essence of bariatric patients with food after surgery. Semi-structured interviews were conducted on a sample of nine participants who had undergone surgery at least two years prior. Findings. Two main themes regarding food intake emerged from the data: (a) food after the first year post-surgery and (b) bariatric surgery is not a magic pill. Upon further analysis, food after the first year post-surgery had four subthemes emerge: diet adherence after the first year post-surgery, food intolerances, amount of food, and tendencies toward coping with food do not magically disappear. Conclusion. Findings revealed that post-operative diet and exercise adherence becomes increasingly difficult as weight loss slows. Many participants find that only after the first year after surgery the work really begins.
