Brief summary
This is a multisite clinical trial of healthy lifestyle programs for middle-to-older-aged adults (50 -74 years) to improve their weight and, therefore, reduce risk for chronic disease. This study will investigate whether a proven, self-directed video-based lifestyle program can be significantly enhanced with the assistance of a coach via videoconference or phone to help people as they adopt healthy eating and exercise behaviors. Additionally, the study will examine what factors might explain why some people achieve better outcomes than others. Understanding this can help to tailor the program to an individual for personalized care in the future. Importantly, this study aims to demonstrate how readily a digital lifestyle program, with or without remote coaching, can be seamlessly delivered to patients at home via the patient portal of their electronic health record. This practical use of existing telehealth tools could be a feasible and effective means to offer behavioral treatments during routine medical care.
Detailed description
This multisite clinical trial uses a 2-stage sequential randomization design to test the adaptive and nonadaptive augmentation of a validated Group Lifestyle Balance (GLB) video program (base intervention) using problem solving treatment (PST), a proven behavior therapy. The GLB video program will be delivered via the patient portal of the electronic health record system. Trained coaches will deliver PST remotely via videoconference or phone. English-speaking adults (N=1029), 50-74 years of age with a body mass index ≥27 and ≥1 cardiometabolic conditions, will be randomized at baseline to base intervention or waitlist control. Participants initially randomized to the waitlist control will be re-randomized after a 12-week control period to receive the base (Group A) or the augmented intervention (Group B), without tailoring based on early weight loss. Among participants initially randomized to the base intervention, responders defined by ≥3% weight loss at 6 weeks will continue the base intervention (Group C); nonresponders who are participants with \<3% weight loss or missing weight data by 6 weeks will be re-randomized to continue the base intervention alone (Group D) or augmented with PST coaching via videoconference (Group E). The investigators hypothesize: (1) the augmented intervention will be more effective than the base intervention both among early nonresponders to the base intervention (adaptive) and among participants in the waitlist control condition (nonadaptive) at 52 weeks; (2) the adaptive augmented intervention will be more efficacious than the base intervention and more efficacious than the waitlist control condition at 12 weeks. Aim 2 is to identify predictors of clinically significant (5%) weight loss for individual patients, using sociodemographic, clinical and behavioral engagement characteristics.

PSS contains 14 items, rated on a 5-point scale ranging from "never" to "very often." After reversing the scores on 7 positive items, a sum of score is calculated with higher score indicating higher perceived stress. Cronbach's alpha ranged from 0.84 to 0.86. |
| Assess changes in sleep disturbance score at 6, 12, 24 and 52 weeks | Baseline, 6 weeks, 12 weeks, 24 weeks, 52 weeks | Sleep disturbance is assessed on the 8-item PROMIS sleep disturbance scale short form which measures symptoms of insomnia. Each item is scaled from 1 (not at all) to 5 (very much). Sleep disturbance score=(Raw sum ×number of items on the short form) / number of items answered. The higher the score the greater sleep disturbance. |
| Assess changes in sleep impairment score at 6, 12, 24 and 52 weeks | Baseline, 6 weeks, 12 weeks, 24 weeks, 52 weeks | Sleep impairment is assessed on the 8-item PROMIS sleep-related impairment scale short form which measures symptoms of daytime sleepiness. Each item is scaled from 1 (not at all) to 5 (very much). Sleep impairment score=(Raw sum ×number of items on the short form) / number of items answered. The higher the score the greater sleep impairment. |
| Assess changes in cognitive functioning at 6, 12, 24 and 52 weeks | Baseline, 6 weeks, 12 weeks, 24 weeks, 52 weeks | Cognitive functioning will be assessed on the PROMIS version 1.0 short-form subscales of Cognitive Abilities and Cognitive Concerns. Each subscale contains 8 items. The Cognitive Abilities items target positive self-assessments of cognitive functioning such as "My memory has been as good as usual" and "I have been able to concentrate." The Cognitive Concerns items are worded negatively and express concerns in the same areas, for examples, "My thinking has been slow" and "I have had trouble shifting back and forth between different activities that require thinking." Items on both subscales use a 5-point rating from "not at all" to "very much." Items are summed to create a total score for each subscale. |
| Assess changes in cardiovascular risk at 52 weeks | Baseline, 52 weeks | The non-laboratory Framingham risk prediction model estimates individuals' 10-year risk of developing any major atherosclerotic cardiovascular disease (CVD) event. The component risk factors are age, BMI, systolic blood pressure, smoking status, presence of diabetes, and medication for high blood pressure. Participants will be asked to confirm their age and report their smoking history at baseline and current smoking status at baseline and 52 weeks. The BMI will be calculated based on participants' self-measured weight data as described above and height measurements abstracted from their EHR. Blood pressure, diagnosis of diabetes, and prescriptions for high blood pressures will also be abstracted from the EHR. |
| Assess changes in number/severity of comorbidity at 52 weeks | Baseline, 52 weeks | The Cumulative Illness Rating Scale (CIRS) is a composite index of the number and severity of medical problems by organ system. It has been validated in diverse populations and settings, including primary care patients, with published guidelines and electronic tools for application and scoring using electronic health record (EHR) data. |
| GLB videos viewed | Throughout the intervention, up to 1 year | GLB videos viewed will be automatically tracked. |
| PST coaching sessions completed | Throughout the intervention, up to 1 year | PST coaching sessions completed will be recorded by coach in REDCap. |
| Self-monitoring of weight | Through study completion, an average of 1 year | All participants will be provided a Fitbit Aria weight scale, a Fitbit Inspire 3 activity tracker, and a study tablet (Samsung Galaxy). Participants will be encouraged to weigh themselves at least 3 days a week throughout the study. Participants will be instructed to weigh themselves on their study-provided Aria scale right after waking up and emptying their bladder (and bowel, if possible) at consistent time. They should wear only a t-shirt and undergarments, and bare feet. The investigators will obtain participants' self-monitored weight data using a developed program for automated daily synchronization via the Fitbit open API. |
| Self-monitoring of activity & sleep | Through study completion, an average of 1 year | All participants will receive a study-provided Fitbit Inspire 3 activity tracker with heart rate and sleep monitor, assistance with account and device setup. Participants will be encouraged to wear their activity tracker for at least 10 hours on 3 or more days a week throughout the study. The investigators will obtain participants' self-monitored number of steps and sleep metrics using a developed program for automated daily synchronization via the Fitbit open API. |
