Dear (Mr./ Mrs) LAST NAME:

Thank you for your participation in the Agricultural Health Study. You and others in North Carolina and Iowa have helped scientists learn more about work and health. By continuing to follow our participants as they grow older, the study will become even more valuable to the growing understanding of our agricultural and rural communities.

We would like to ask you a few questions in a telephone interview to update the information you have already provided. What you tell us now might help scientists find answers to questions that would be very important to farmers and others – even to future generations.

The Agricultural Health Study (www.aghealth.org) is directed by the National Institutes of Health. All participation is voluntary. We will keep your answers confidential as provided by law. Identifiers will be stored in locked files or in password-protected computerized files available only to authorized research staff.

If you have any questions or concerns before we call you or if your telephone number has changed from (TELEPHONE NUMBER), please call us at 1.800.4AG.STUDY.

You are especially valuable to the study! It is very important that we include you again even if you are retired or no longer farming.

We look forward to speaking with you.

Sincerely, Sincerely,

Charles Knott, M.P.A. Michael C.R. Alavanja, Dr. P.H.

North Carolina Director Project Officer, National Cancer Institute
