The Eastern Caribbean Health Outcomes Research Network (ECHORN)is a regional research network dedicated to research, training, and collaboration to reduce chronic disease in Caribbean communities. The network is anchored by the ECHORN Cohort Study, which follows 3,000 adults in Puerto Rico, the US Virgin Islands, Trinidad and Tobago, and Barbados. The cohort study examines risk and protective factors for preventing, developing, and treating diabetes, hypertension, and other non-communicable diseases. Study teams have collected a wealth of data about community health in each region, including information about residents’ nutritional intake, health behaviors, social experiences, access to healthcare, and overall health. These findings are publicly available through Explore ECHORN, a secure, online data platform where community members can search through and download study information. The ECHORN team hopes that making this data free and available for public use will support a healthy Caribbean.
