Effect of an mHealth Intervention Using a Pedometer App With Full In-Person Counseling on Body Composition of Overweight Adults: Randomized Controlled Weight Loss Trial (Preprint)

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, <i>t</i>=–11.242, <i>P</i><.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.

Subjects were 23 obese men and women who received a behavioral weight control program and were randomly assigned to one of two experimental conditions: (1) subjects were weighed at the beginning of each treatment session and were encouraged to weigh themselves at home for “continuous feedback” or (2) subjects were not weighed at group meetings and were instructed to avoid weighing themselves at home in order to “concentrate on behavioral change.” At posttreatment and at 4-wk. follow-up, the groups did not differ for change in bodyweight or change in percentage overweight. There was, however, a tendency for subjects who did not weigh themselves to lose more weight and to display lower attrition than weighed subjects at posttreatment and at the 4-wk. and 6-mo. follow-ups.

Evaluation Survey

Background: Regular physical activity is crucial for healthy aging, but older adults are the least active age group. This study explored the feasibility, acceptability, and efficacy of a multilevel mHealth intervention for increasing physical activity of older adults living in a retirement community. Methods: Participants included 54 older adults (mean age = 81.2 y, 77.8% female, 98.1% white) living in a retirement community. Participants received a Fitbit Zip and access to a multilevel mHealth physical activity intervention (MapTrek Residential) for 8 weeks. Physical activity (in steps per day) and intervention compliance (days worn) were measured objectively with the Fitbit for 12 weeks (8-wk intervention plus 4-wk follow-up). Psychosocial outcomes (social support, self-efficacy, and outcome expectations) were assessed at baseline and 8 weeks. Acceptability outcomes were assessed with an open-ended process evaluation survey and focus groups. Descriptive statistics and linear mixed models were used to examine intervention effects. Results: Participants increased daily steps from 5438 steps per day at baseline (95% CI, 4620 to 6256) to 6201 steps per day (95% CI, 5359 to 7042) at week 8 (P < .0001) but this was not maintained at 12 weeks (P = .92). Conclusions: Our multilevel mHealth physical activity intervention was effective for increasing physical activity older adults over 8 weeks. Additional research focused on maintaining physical activity gains with this approach is warranted.

233 Background: Excess weight is one of the few modifiable risk factors for incident breast cancer. Many programs can achieve a 7% weight loss but few can maintain it over time. Training women to use self-help resources over the internet has potential for reducing intervention costs and ensuring program maintenance. Methods: 50 overweight/obese (BMI≥27.5 kg/m2) women at increased risk of breast cancer (Gail score≥1.7) were identified from a mammography registry and enrolled in the HELP pilot study and randomized with 2:1 probability to a 12-week lifestyle intervention or a comparison group. Twelve telephone-based coaching calls trained participants to use a free, publicly available website to set goals and track performance for dietary intake and physical activity. The comparison group received information but no training. At baseline and 12 weeks, participants were weighed, fitted with an accelerometer for physical activity pattern, and completed questionnaires. Results: At baseline, participants were 60.9±0.79 years of age with a BMI of 33.1±0.60 kg/m2; 39% were daily internet users. Thirty-three were randomized to the intervention group with 91% completing follow-up. Fifty-four percent were able to use the website reliably and found it to be helpful, including 44% of previously nondaily internet users. At 12 weeks, intervention group participants who found the website helpful had lost 5.6±0.7 kg, or 6.7% of initial weight, intervention participants who did not find it helpful lost 0.8±0.9kg or 1.1% of initial weight and the comparison group gained 1.0±0.94 kg (89% follow-up) The between-group difference weight change was 4.2 kg (p<.0001). 74% of intervention group participants lost weight, compared to only 34% of women assigned to the comparison group. Conclusions: A 12-session telephone coaching program to train women to use publicly available web-based weight loss programs effectively achieved a large short-term weight loss among the majority of participants. Further follow-up is needed to identify how well the initial weight loss is maintained without further intervention assistance.

Bariatric Patients

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.
