Risk screening for cardiovascular disease and diabetes in Latino migrant farmworkers: a role for the community health worker.

ABSTRACT

Diabetes and heart disease are two of the leading causes of death for Hispanics living in the United States (American Heart Association [AHA] in Circulation 123e18-e209. doi 10.1161/CIR.0b013e3182009701 , 2010). As the Hispanic population continues to grow, the need for low-cost, non-invasive methods to detect at risk populations for such diseases becomes more important. Once at risk individuals are detected, prevention strategies can be implemented. Studies have shown that Latino community health workers (CHWs) are effective educators, patient advocates and health promotion motivators for patients with known heart disease or diabetes. This pilot study examined the accuracy with which Latino CHWs could determine migrant farmworkers at risk for diabetes or cardiovascular disease (CVD) in rural Virginia. This quasi-experimental study supports the hypothesis that Latino CHWs can use non-invasive diabetes and CVD screening tools with similar accuracy as a registered nurse. The screening tools used were the American Diabetes Association's diabetes risk calculator and a non-laboratory screening tool for CVD risk designed by Gaziano et al. (Lancet 371923-931, 2008). The terms Latino and Hispanic will be used interchangeably.
