DATA REQUESTS

Extracts of the data files will be provided to qualified researchers approved by the Agricultural Health Study Executive Committee. Refer to Agricultural Health Study Policy 2-4.

To request data, complete the AHS Request Form (Word, PDF) and appropriate variable checklist(s). Note that a signed copy of the Pledge of Confidentiality (see p6) must be received in hard copy or by FAX, before data request can be fulfilled.

The variable checklists are in Excel format, with each tab of the spreadsheet representing a distinct data file – for example, the Private Applicator file, the Spouse file, etc. The Phase I files and variables are listed in P1_checklist.xls, and the Phase II files and variables are listed in P2_checklist.xls. Non-phase specific files and variables such as the Demographic file, Mortality file, Cancer Registry File, and Buccal Receipt File are included in the DemographicRegistryBiospecimen_checklist.xls file.

The Cancer Analytic Lag File (CALF) file combines pesticide exposure data for all applicators in the study. It contains data from both Phase I and Phase II questionnaires and selected cancer data for incident cancers.

On the first tab (i.e., worksheet) of each checklist, column B provides a listing of all the files available. Indicate from which file(s) you are requesting data by placing an X in column A next to each file of interest. On the individual file tabs, the variable names are in column B and the variable labels are in column C. Place an X in column A next to each variable being requested. Note that a number of linking and demographic variables are marked by default.
