The Jackson Heart Study (JHS) provides a rare and valuable research resource maintained under the joint stewardship of the JHS institutions and the National Heart, Lung and Blood Institute (NHLBI). The NHLBI and the researchers it supports have a responsibility to the public and to the scientific community, using these resources, to encourage as rapid scientific progress as possible, subject to appropriate terms and conditions.  This website segment provides researchers with terms and conditions for the use of JHS data for ancillary studies and manuscripts, and as well for the collection of additional data from the JHS cohort. By navigating this section of the website, researchers will find ancillary studies guidelines, proposal form, forms required for data access, a checklist, as well as guidelines and forms for publications and presentations. The Publications and Presentations Guidelines include specific steps and schematics for the manuscript proposal process as well as the manuscript submission and approval process. A one-page summary of the ancillary studies and publication and presentation guidelines is also available for quick reference.  Researchers will find a link to the JHS Study Components which includes  a listing of the data collected in Exams 1 and 2 and projected for Exam 3. Exams 1 and 2 Manuals and Forms are also accessible via this link. Additionally, researchers will find a dynamic list of JHS Investigators and collaborators that is frequently updated. There is a link to a description of our Genetics focus and ancillary and sub- studies in progress. There is also a link to JHS publications.  A series of  figures illustrate  selected demographics and risk factors related to the JHS cohort. The details of obtaining data are included under “Data Access”.
