Community Team Lifestyle Immersion Program for Chronic Disease Prevention and Control

African Americans continue to bear disproportionate chronic disease morbidity and mortality, and tend to report lower benefits from clinical trials that include lifestyle modifications in addition to pharmaceutical management. This project uses hypertension as an index case for other chronic ailments such as heart disease, diabetes, kidney failure, and obesity, especially as their control measures are similar. Several clinical trials over the last five decades have emphasized the importance of supportive lifestyle modification in the control of chronic disease that include a healthy diet, physical activity, quitting tobacco use, reducing alcohol use to the minimum, self-management of the disease, and adequate sleep. Although socioeconomic factors can impact disease management outcomes, African Americans may require additional motivational support to first accept the notion of change of lifestyle and to adhere to the changes that may be a major shift in their eating and exercise habits. The need to positively impact chronic disease, particularly hypertension, morbidity and morbidity in the African American population deserves both pharmaceutical and non-pharmaceutical approaches. This intervention incorporates elements of the American Heart Association prescription for health, Life's Simple 7 (LS7) lifestyle modification, the Dietary Approaches to Stop Hypertension (DASH) eating plan, provides the knowledge and skills necessary for success, and introduces the motivation boost of participating in teams of 4-6 participants. The primary intervention outcome is adherence to the seven elements of LS7, measured by LS7 Scores at enrollment, and at 6- and 12-months follow-up. Secondary outcomes will include changes in SBP/DBP, BMI, Waist girth, and A1C. The study shall compare Team versus Individual study arms for participants recruited and managed in the health center and the home settings separately and combined. Intermediate outcomes will include, and not limited to biomarkers such as urine sodium, serum Plasminogen activator inhibitor-1 (PAI-1) for hypertension, Interleukin 6 (IL6), and C-reactive protein (CRP) for obesity.

The goal is to enroll 220 participants, half from health institutions (Nashville General Hospital & Mathew Walker Comprehensive Health Center) and the other half from the community (MDHA residence, Health Fairs, Churches etc.). Half of the participants will be people already diagnosed with hypertension (BP 140/90 or higher, or on hypertension medication) and half will be those at increased risk of developing hypertension with BP measurement 130/80 and above.

The study will be implemented in three phases:

Phase 1: Health Behavior Assessment. Phase 2: Intervention Development. Phase 3: Intervention Effectiveness Evaluation.
