Arm Label

Group-Based

Self-Directed

Arm Description

The Group-based Program uses an ecologically valid setting in which participants exercise, prepare foods, and eat together to facilitate the emergence of old habits and replace them with healthy alternatives. The intervention team consists of a health psychologist, registered dietitian, and health coach. They co-facilitate group meetings for 15 participants that are held weekly for 3 months, bi-weekly for 3 months, and then monthly in participant-led maintenance meetings. Each session includes: weigh-in and physical activity (20 min), cooking demonstration (20 min), and a shared vegetable dish with discussion (50 min). The maintenance phase (months 7 to 24 post randomization) consists of support and health-related topics of the participants' own choosing. Progress reports with lab results are sent to participants and primary care physicians.

The Self-Directed lifestyle program represents enhanced usual care based upon what is currently offered in primary care in the United States for lifestyle treatments for adults with metabolic syndrome. Usual care is enhanced by: 1) lifestyle education for management of metabolic syndrome provided in evidence-based tip sheets from nationally recognized organizations; 2) provision of a Fitbit for self-monitoring physical activity; 3) access to a website containing all education materials; and 4) progress report letters with lab results sent to participants and primary care physicians after completion of each assessment

Primary Outcome Measures

Remission of Metabolic Syndrome
Compare the Group-Based and Self-Directed arms on the proportion of participants who are in remission of the metabolic syndrome (MetS) at 2 years. MetS is defined by the Joint Interim Statement of the IDF, NHLBI, AHA, WHF, IAS, IASO as having 3 or more risk factors for cardiovascular disease. To be considered in remission of MetS the participant must have less than 3 of the following 5 criteria: 1) Waist circumference based on AHA/NHLBI (ATP III) cut points of ≥ 102 cm for men and ≥ 88 cm for women; 2) Fasting triglycerides ≥150 mg/dL or treatment for elevated triglycerides; 3) Fasting HDL cholesterol <40 mg/dL in men or <50 mg/dL in women, or treatment for low HDL; 4) Systolic blood pressure ≥130 m Hg, diastolic blood pressure ≥85 mm Hg, or treatment for hypertension; and 5) Fasting plasma glucose 100-125 mg/dL. Analysis will be performed on pre-determined subgroups: education, sex, site, weight, BMI, MetS severity, race, income # of comorbidities, self-efficacy, and age.

Secondary Outcome Measures

5. Study Description

Brief Summary
This is a multi-center behavioral randomized trial with the aim of comparing a group-based lifestyle intervention with a self-directed lifestyle intervention on remission of the metabolic syndrome over 2 years of follow-up.
Detailed Description
The purpose of this trial is to determine the efficacy and cost-effectiveness of the Group-Based and Self-Directed ELM lifestyle programs when offered on a national level. A multi-site randomized trial will be conducted on 600 patients with the metabolic syndrome (MetS) by five national sites, each of which will randomize 120 patients to the Group-Based or Self-Directed programs. The Group-Based program targets healthy eating, physical activity, and stress reduction and is based upon neuroscience studies showing that mindful habits provide resilience against the power of emotions to subvert intention, and social science studies showing that sustainability is enhanced by support from a health network. The Self-Directed program represents enhanced usual care based upon what is currently offered in medicine and wearable technology for treatment of adults with MetS and its components. The primary outcome is remission of MetS at 2 years. Secondary outcomes include cost-effectiveness, vegetable intake, physical activity, and mindful awareness.

Title
Impact of pandemic
Description
Compare results between participants in Wave 1 and those in Waves 2, 3, & 4. on the primary outcome at 2 years. MetS is defined by the Joint Interim Statement of the IDF, NHLBI, AHA, WHF, IAS, IASO as having 3 or more risk factors for cardiovascular disease. To be considered in remission of MetS the participant must have less than 3 of the following 5 criteria: 1) Waist circumference based on AHA/NHLBI (ATP III) cut points of ≥ 102 cm for men and ≥ 88 cm for women; 2) Fasting triglycerides ≥150 mg/dL or treatment for elevated triglycerides; 3) Fasting HDL cholesterol <40 mg/dL in men or <50 mg/dL in women, or treatment for low HDL; 4) Systolic blood pressure ≥130 m Hg, diastolic blood pressure ≥85 mm Hg, or treatment for hypertension; and 5) Fasting plasma glucose 100-125 mg/dL. Analysis will be performed on pre-determined subgroups: education, sex, site, weight, BMI, MetS severity, race, income # of comorbidities, self-efficacy, and age.
Time Frame
Measured at 24 months following treatment assignment.
Other Pre-specified Outcome Measures:
Title

Description
To evaluate the impact of ELM lifestyle programs on reversing the metabolic syndrome for specific subgroups. These subgroups include: education, sex, site, weight, BMI, metabolic syndrome severity, race, income, number of comorbidities, self-efficacy, and age.

To meet metabolic syndrome criteria the participant should have ≥ 3 of the following five criteria: Waist circumference based on AHA/NHLBI (ATP III) cut points of ≥ 102 cm for men and ≥ 88 cm for women Fasting triglycerides ≥150 mg/dL or treatment for elevated triglycerides Fasting HDL cholesterol <40 mg/dL in men or <50 mg/dL in women, or treatment for low HDL Systolic blood pressure ≥130 m Hg, diastolic blood pressure ≥85 mm Hg, or treatment for hypertension Fasting plasma glucose 100-125 mg/dL (range inclusive) Greater than 18 years of age Exclusion Criteria: Unable to walk 2 consecutive blocks without assistance, based on patient report.
