Miami Healthy Heart Initiative (MHHI) a Randomized Study of Behavioral Risk Factors for Cardiovascular Disease in Latino and Hispanic Patients With Poorly Controlled Diabetes

Disparities in the epidemiology of cardiovascular disease (CVD) risk factors among Latinos have been extensively described; however, traditional medical models of CVD risk reduction have not been very effective in Latinos. One promising strategy is the use of community-based community health workers (CHWs). CHWs have long been used in Latin-America as an integral part of their health care delivery system. Further, preliminary data from our prior pilot diabetes self-management CHW program have shown improvements in lipids. However, because of a lack of effectiveness data from studies using rigorous experimental designs, the adoption of the CHW model has been quite limited both locally and nationally. In MHHI, our goal is to examine the effectiveness of a CHW intervention in CVD risk reduction among Latinos.

The investigators propose to examine the effectiveness of a multilevel CHW intervention as an adjunct to routine primary care in reducing CVD risk factors among diabetic Latinos Miami. The UM Jay Weiss Center which has substantial experience in Community Health Worker Program will take the lead role in the development and implementation intervention of the CHW program.

The study design is a randomized controlled trial (RCT) of 300 Latino patients ages 35-70 with poorly controlled diabetes (AIC >=8.0) followed at the Ambulatory Care Clinic (ACC) of Jackson Memorial Hospital (JMH).

Primary Objective: To determine if the CHW intervention results in lowering of CVD risk factors including blood pressure, LDL cholesterol, and diabetes control (AIC) as measured by the Total Framingham Risk Score (FRS).

Secondary Objectives: To determine if the CHW intervention results in improvements in the following putative mechanisms that may influence the FRS:
