Brief Summary:
The purpose of this RCT is to examine the efficacy of the Group Lifestyle Balance (GLB) program adapted for people with stroke (CVA) on primary (weight) and secondary outcomes at 3, 6, 12 months from enrollment into the program.

Condition or disease Intervention/treatment Phase
Stroke Behavioral: Group Lifestyle Balance Other: Usual Care Not Applicable

Detailed Description:
Weight gain greatly increases the risk of chronic diseases after stroke such as diabetes, metabolic syndrome, pulmonary and heart disease. Approaches to weight-loss are lacking, yet necessary, due to the unique physiological and cognitive needs of persons with CVA. There is evidence that interventions that improve physical activity and healthy eating behaviors concurrently offer greatest potential for weight-loss. The Group Lifestyle Balance (GLB) intervention is a 12-month, evidence-based weight-loss program that has been used extensively with the general population, but not with people after CVA. Investigators modified the program to meet the needs of people post stroke (GLB-CVA).

Arm Intervention/treatment
Experimental: GLB Weight-Loss Intervention
The GLB program, adapted for individuals with stroke, will be delivered to participants over a 12-month period, divided into 22 in-person, group sessions. The intervention promotes 5-7% weight-loss by reducing calories and increasing exercise (150 minutes of moderate physical activity per week).
Behavioral: Group Lifestyle Balance
The Group Lifestyle Balance (GLB) program is a self-management intervention that has been shown to result in weight-loss and reduce the risk for Type 2 diabetes through increased physical activity and healthy eating behaviors in the general population. The GLB is a direct adaptation of the Diabetes Prevention Program, both developed at the Diabetes Prevention and Support Center at the University of Pittsburgh. The GLB is designed for delivery in a group-based, community setting, and has resulted in weight-loss in a variety of settings, such as community centers, churches, worksites, and healthcare systems. The GLB curriculum used in this study has been adapted for people with stroke.

Wait-List Control
The wait-list control group will receive no intervention for 6 months after enrollment. After the 6 month control period, the wait-list control group will receive the GLB Intervention.
Other: Usual Care
Participants randomized to the wait-list control group will receive usual care for 6 months before beginning the modified GLB program.




Primary Outcome Measures :
  1. Change in weight [ Time Frame: Baseline, 3, 6, 12 months ]
    Will be obtained using the same scale over the study period that is accessible to people with and without a mobility device (e.g., walker; wheelchair).


Secondary Outcome Measures :
  1. Physical Activity [ Time Frame: Baseline, 3, 6, 12 months ]
    Accelerometers will be worn by participants for the duration of the study to objectively track physical activity participation (amount and intensity). Participants will be given the Actigraph accelerometer at the beginning of the study and will be provided with verbal and written instructions.

  2. Arm Circumference [ Time Frame: Baseline, 3, 6, 12 months ]
    Arm circumference measured at mid-upper arm following ACSM guidelines. A total of three measurements will be taken and an average of the three will be used. Measurements will be taken in centimeters.

  3. Blood Pressure [ Time Frame: Baseline, 3, 6, 12 months ]
    Using an automatic cuff (average of three readings, patient seated) diastolic and systolic scores will be recorded

  4. Cholesterol [ Time Frame: Baseline, 3, 6, 12 months ]
    Fasting venous sample will be obtained. Coordinators are trained phlebotomists.

  5. Risk of Diabetes [ Time Frame: Baseline, 3, 6, 12 months ]
    The Framingham Heart Study diabetes risk score 95 will be calculated using predictors including age, gender, fasting glucose, BMI, HDL cholesterol and triglyceride levels, blood pressure, and parental history. Risk score calculator and regression model are free and used in GLB weight-loss trials. Risk score calculator and regression model are free and used in GLB weight-loss studies. Each risk predictor is assigned points ranging from 2-10. Risk factors are combined and a total score is calculated, with higher scores designating greater 8-year risk.

  6. 10 Meter Walk Test (10MWT) [ Time Frame: Baseline, 3, 6, 12 months ]
    Assesses walking speed in (m/s) which is correlated to mobility in the community, capacity to perform ADLs, risk of falls, re-hospitalization, and risk of cognitive decline.

  7. 6 Minute Walk Test (6MWT) [ Time Frame: Baseline, 3, 6, 12 months ]
    Assesses distance walked over 6 minutes as a sub-maximal test of aerobic capacity. Endurance is essential to participate in community-based activities.

  8. Perceived Social Support [ Time Frame: Baseline and 12 months ]
    The Multidimensional Scale of Perceived Social Support (MSPSS) is comprised of 12 questions with a 4-item subscale. The MSPSS is designed to assess perception of social support from friends, family, and significant others

  9. Self-reported activities of health using the Self-Rated Abilities for Health Practice scale [ Time Frame: Baseline and 12 months ]
    Measure includes 28 items that assess health practices among people with disabilities and yields a total Health Practices score plus 4 subscales scores regarding Exercise, Nutrition, Health Practices, and Psychological Well Being. Items are rated on a 5-point scale from 0 'not at all' to 4 'completely.' Scores range from 0-28 with higher scores indicating higher exercise self-efficacy.

  10. Neighborhood walkability using Walk Score® [ Time Frame: Baseline ]
    Walk Score® is publicly available and measures the walkability of any address using a patented system. For each address, Walk Score ® analyzes hundreds of walking routes to nearby amenities and awards points based on distance to each amenity. Walk Score® also measures pedestrian friendliness by analyzing population density and road metrics such a block length and intersection density. Scores are given on a scale of 0 to 100.

  11. Resting Metabolic Rate [ Time Frame: Baseline ]
    MedGem® is an FDA cleared and validated indirect calorimetry device. It is handheld and measures oxygen consumption (V02) to determine resting metabolic rate (RMR).

  12. Behavioral Risk Factor Surveillance [ Time Frame: Baseline, 3, 6, 12 months ]
    The BRFSS is a state-based system of health surveys that collects information on health risk behaviors, preventative health practices, and health care access primarily related to chronic disease and injury. The GLB-TBI uses the two subscales of Healthy Eating and Physical Activity from the 2017 version of the BRFSS. It consists of 14 items.

  13. Participant quality of ife [ Time Frame: Baseline, 6, 12 months ]
    Quality of life will be assess using the stroke impact scale (SIS), which assesses 8 dimensions of health-related QOL specific to people post CVA including subscales (using a 5pt Likert scale) assessing strength, memory and thinking, emotion, communication, activities of daily living, mobility, hand function, and participation/role function

  14. Stressful Life Events using the Holmes and Rahe Stress Inventory [ Time Frame: Baseline and 12 months ]
    This inventory consists of 40 life events and asks the participant to recall if any of the events happened within the previous year (e.g., death of spouse; personal illness; change in sleep). Endorsement of these events are totaled and higher scores indicate a greater amount of stressful life events. Point values for the Holmes and Rahe Stress Inventory were weighted and summed for each individual based on scoring instructions. Individuals who scored 150 points or less were categorized as low susceptibility to a health breakdown in the next two years, 151-300 points were 50% chance of health breakdown, and 301 points or more were 80% chance of health breakdown.

  15. Executive Function and Cognition using the Montreal Cognitive Assessment [ Time Frame: Baseline, 3, and 12 months ]
    The MOCA is a brief, 8-section assessment of various cognitive domains including executive function, memory, language, attention, concentration, orientation, and working memory in neurologic populations.110 Each item on the MOCA is allocated a set of points adding up to 30.

  16. Habit Formation [ Time Frame: Baseline, 3, and 12 months ]
    The self-reported habit index (SRHI) measures the self-reported perceptions of habit strength for an identified behavior. It consists of 12 items for each selected behavior and uses a 7-point Likert scale from "completely disagree" to "completely agree." Higher totals represent greater perception of habit strength. The SRHI showed high reliability across four studies with alphas of .89, .92, .89, .94, .95, .94, and .85.

  17. Stroke Severity [ Time Frame: Baseline ]
    The Modified Rankin Scale (MRS) measures the degree of disability or dependence for daily activities of people who have had a stroke. The MRS is an ordinal scale with six categories ranging from zero (no symptoms) to five (complete physical dependence). A score of six signifies death.

  18. Pain Interference [ Time Frame: Baseline, 3, 6, and 12 months ]
    The Pain Interference-Short Form is taken from the Patient-Reported Outcomes Measurement Information System (PROMIS). This measure is used to assess adult self-reported consequences of pain and pain consequences (e.g. interference in social, cognitive, emotional, physical and recreational activities). This measure consists of four questions with five response option ranging from one to five. The sum of all responses creates a total raw score. This measure is normed to the US general population

  19. Sleep Disturbance [ Time Frame: Baseline, 3, 6, 12 months ]
    The Sleep Disturbance-Short Form 4a is taken from the Patient-Reported Outcomes Measurement Information System (PROMIS) and used to assess adult sleep disturbance profiles. This measure has four questions, each with five response options ranging in value from one to five. The sum of each response creates a total raw score. The measure is normed to the US general population.

  20. Waist Circumference [ Time Frame: Baseline, 3, 6, and 12 months ]
    Waist circumference will be measured at the umbilicus following ACSM guidelines. A total of three measurements will be taken and an average of the three will be the final measurement used. Measurements will be scored in centimeters.

  21. HbA1c [ Time Frame: Baseline, 3, 6, and 12 months ]
    Fasting venous sample will be obtained for hemoglobin a1c to assess average blood sugar level over the past 2-3 months. Coordinators are trained phlebotomists.

  22. Triglycerides [ Time Frame: Baseline, 3, 6, 12 months ]
    Fasting venous sample will be obtained. Coordinators are trained phlebotomists.

  23. Blood Glucose [ Time Frame: Baseline, 3, 6, 12 months ]
    Fasting venous sample will be obtained. Coordinators are trained phlebotomists.
