Hispanic Community Health Study Study of Latinos

Study Objectives

The Hispanic Community Health Study (HCHS) Study of Latinos (SOL) is an observational study of Hispanic/Latino populations living in the United States. The study aims to define the prevalence of disease and rate of development of new disease within these groups and to determine the role of risk factors and acculturation on the development of new disease. The study is sponsored by the National Heart, Lung, and Blood Institute (NHLBI) and six other institutes, centers, and offices of the National Institutes of Health (NIH).

Between 2008 and 2011, 16,000 participants were enrolled in this study from four field centers (Miami, FL; Chicago, IL; Bronx, NY; San Diego, CA). On their first study visit each of the subjects filled out surveys about their current health status. They also underwent a battery of tests which included blood tests, a dental exam, a hearing test, a sleep examination and lung function testing. The study participants are followed with phone surveys that occur yearly to determine if they've experienced any changes in their health status.

Between 2014 and 2017, each of the participants is invited to undergo a second visit, which will also include a battery of new tests. As part of this visit, the participants will have an echocardiogram. These echocardiograms will be used to identify the prevalence of structural heart disease amongst the study participants and serve to enhance understanding about the biological mechanisms that lead to heart disease in these populations. This manual will serve to instruct on the proper conduct of the visit 2 echocardiogram by the HCHS-SOL field centers.
