Study Data

Strong Heart Study data are shared with researchers following Resource and Data Sharing Policies, which include review and approval from the Strong Heart Steering Committee and Strong Heart Study participating tribes.   The participating tribes of the Strong Heart Study continue to follow established protocols for Resource and Data Sharing to efficiently review and approve data requests which include those from ancillary and sub-studies, as well as authors of approved paper proposals.   

Please refer to the following sections for additional information:

Data and Summary Statistics Request Policy


  1. SHS data will be distributed only to substudies or ancillary studies that have been approved by the SHS Steering Committee (SC) and are funded. Approval of a study by the SC does not mean that the PI of the study will have the needed data. The SHS SC reserves the right to not distribute the data to the study PI and to designate a SHS center to perform the needed analysis.
  2. The SC will notify the Coordinating Center (CC) of the approval of any substudies and ancillary studies immediately after the approval by sending a copy of the approval letter from the Chair of SC to the CC.
  3.  When funding of a substudy or ancillary study is secured, the investigator will notify the SHS CC and data request will be submitted to the CC at appropriate stages. At each stage the requestor can only request the data needed at that time.
  4. A requestor must complete the online SHS Data Request form and the SHS Data Distribution Agreement form, and then must upload both completed forms and attach a copy of the protocol explaining the study and intended uses of the requested SHS data through the REDCap survey form.
  5. The requestor must detail the specifics of the data request (variable names, Phase, Center, etc.) on the data request form.
  6. The CC will check the availability of the requested data and notify the requestor if any data are not available.
  7. Unless a data request is complex or requires additional work (for example, development of new derived variables), the CC will make the data available for secure transmission usually in approximately 2 weeks after approval of the request by the CC. The requestor must contact Ms. Kimberly Hollabaugh to arrange the details of the transmission.
  8. If the request is complex, more time may be required; the requestor will be given an estimate of the earliest transmission date.
  9. For each paper resulting from a substudy or ancillary study using SHS data, the requestor will comply with the SHS publication policy.
  10. The CC will maintain a list of approved data requests and the status of progress in fulfilling the requests. The list will be maintained on the SHS website.


Summary statistics of SHS data may be requested by submitting a detailed description to the SHS Steering Committee for review and approval. The description must include the purpose of the request and describe in detail the summary statistics needed. If the request is approved, the SC will forward the request to the CC. The CC will review the request, notify the requestor of the time needed to calculate the statistics and deliver them in a timely manner. No raw or derived data will be distributed to requestors for the purpose of calculating summary statistics.
