This study aims to determine whether a 6-month multilevel intervention involving problem-solving training, exercise training and support from community health workers is more effective in improving outcomes for individuals with low socioeconomic status, type 2 diabetes, obesity, and early cardiac dysfunction than receiving education and access to a community exercise facility.
This randomized controlled trial employs a 2:1 allocation ratio. The study aims to include 402 individuals from Baltimore City and Hagerstown, Maryland, characterized by low neighborhood and individual socioeconomic status, type 2 diabetes, obesity, and evidence of subclinical heart dysfunction, without a prior clinical diagnosis of heart failure. The 6-month multi-level intervention consists of three key components: 1. Problem Solving - Diabetes Self-Management Training (DECIDE): Participants will engage in a biweekly evidence-based behavioral change program known as DECIDE. This program focuses on problem-solving training, aiding individuals in managing chronic conditions by overcoming obstacles and challenges. It aims to enhance self-care, improve control of metabolic risk factors, and includes tailored education on heart failure prevention. 2. Community Health Worker Support: Participants will receive ongoing support from community health workers as part of the intervention. These workers will conduct telephone and/or home visits at least monthly, offering assistance in following areas: * Reinforcing patient education about disease self-management * Helping patients access care and addressing barriers to care and treatment * Serving as facilitators and navigators to clinical care, social services, and other community resources * Providing encouragement and support to engage, activate, and empower patients and their support systems 3. Health Coaching and Partnership with Community Facilities: Participants will engage in supervised aerobic and resistance exercise training at the local Young Men's Christian Associations (YMCAs). The participants will receive instructions on gradually increasing the activity levels throughout the 6-month intervention to achieve physical activity goals (150 minutes of moderate to vigorous exercise per week).

Change in specific problem solving skills as assessed by Health Problem-Solving Scale (HPSS) subscales.
The following Health Problem-Solving Scale (HPSS) subscales will be assessed: Impulsive/Careless Problem Solving (IPS), Avoidant Problem Solving (APS), Negative Transfer (NTR), Negative Motivation/Orientation (NMO). Subscale scores are calculated by summing the scores for each item within the respective subscales. Higher subscale scores indicate more of that problem-solving characteristic. The score range for each subscale is as follows: IPS (0-32), APS (0-28), NTR (0-44), NMO (0-20). Total score range 0-124.
Time frame: Baseline, 6 month follow up, 12 month follow up
Changes in self care measures as assessed by Summary of Diabetes Self-Care Activities Scale (SDSCA)
The Summary of Diabetes Self-Care Activities Scale (SDSCA) is a tool used to measure diabetes self-care activities. 12-items with 5 sub-scales (diet, exercise, home blood glucose testing, foot care, smoking status). The respondent is asked how many days in the past week the behavior was performed (ranges from 0 to 7); The result is an average score between 0 and 7 with higher score indicating better diabetes self-management behavior.

Changes in disease knowledge as assessed by Diabetes and Cardiovascular Disease (CVD) Knowledge Test
The Diabetes and CVD Knowledge Test comprises 16 items, featuring both multiple-choice and true-or-false questions. This assessment tool gauges individuals' comprehension of diabetes, its impact on health, and optimal strategies for managing the condition. The possible score range is 0-17. A higher score indicates a better understanding of diabetes and cardiovascular disease.
Time frame: Baseline, 6 month follow up, 12 month follow up
Changes in physical activity as assessed by Modified Physical Activity Questionnaire (MPAQ)
The MPAQ is a tool used to estimate the frequency in days (number of times per month) and in time (minutes) someone participated in physical activity (e.g. biking, walking, swimming, etc.). Hours per week for all activities are summed to determine activity hours per week averaged over the past year. A higher sum indicates more physical activity. Values can also be weighted by their estimated metabolic cost and expressed as metabolic equivalent (MET) hours per week. Higher METs are associated with better outcomes. The MPAQ also assesses inactivity, such as the average number of hours per day spent watching television or being confined to a bed or chair for more than 1 week. A higher average indicates less physical activity.

Change in Metabolic Syndrome Severity Z score
Metabolic Syndrome Severity (MetS) Z score calculates an individual's metabolic syndrome severity score by examining five key markers: waist circumference, blood pressure, triglycerides, HDL, and fasting glucose. Score typically ranges from -5 to 5. Higher scores indicate greater metabolic syndrome severity.
Time frame: Baseline and 6 month follow up
Change in self-management as assessed by the Patient Activation Measure (PAM-13).
The Patient Activation Measure is a 13-item survey that will assess an individual's knowledge, skills and confidence to managing one's health and healthcare. The PAM scores is calculated and then transformed to a scale with a range from 0-100. A higher PAM score indicates higher patient activation. The score can also be converted into four activation levels: 1 - not believing activation important, 2 - lack of knowledge and confidence to take action, 3 - beginning to take action, 4 - taking action.
