Attachment 17-1: BEEA IA Introductory Letter for Randomly Selected and
Recently Exposed Group Participants
Date
To:
Mr.
From: Charles Lynch, M.D., Ph.D.
Director, Agricultural Health Study in Iowa
Thank you for your participation in the Agricultural Health Study (AHS). We appreciate
the time you have already taken over the years to complete the study interviews and
questionnaires.
A new study is underway for the AHS that is designed to measure biologic effects in
relation to different farming exposures and activities. Overall, 2,200 Agricultural Health Study
members and controls will be enrolled over the next several years of the study. The study is being
funded by the National Cancer Institute.
This study will examine the properties of blood, saliva, and urine as well as dust samples
from a subset of households that may be related to environmental or occupational factors and lifestyle characteristics. Improving our understanding of these relationships will help us in our
evaluation of possible links between pesticide exposure and disease. We are particularly
interested in cancers. We believe our long-term study of rural Iowans may help us better
understand these illnesses and eventually prevent them.
We plan to call you within a couple of weeks to determine if you are truly eligible to
participate in this study. Up to 5 call attempts will be made at different times of the day and at
different days to reach you. Among the questions we will ask are three aimed toward improving
our understanding of your cancer screening practices. The call will take 10 minutes or less.
Once we determine your eligibility for the study and you tell us that you are interested in
participating, we will schedule a home visit with you, with the possibility of completing two
additional home visits for a select number of participants. Prior to the home visit, you will receive
materials from us including two copies of the consent document, a reminder card for key
elements of the questionnaire, and urine collection materials. At the time of the home visit we
will obtain your signed consent to participate in this study. We will also conduct a 30-minute
interview to obtain information about your recent medication use, medical conditions, smoking
status, alcohol consumption, and pesticide use during the current/previous growing season. We
will ask you to provide about 4 tablespoons of blood, saliva, and a first morning sample of urine.
This will take about 30 minutes. In all, the visit would take about 1.5 to 2 hours of your time.
All of the information we collect will be used only for research purposes and will be kept
strictly confidential. However, federal regulatory agencies and the University of Iowa
Institutional Review Board (a committee that reviews and approves research studies) may inspect
and copy records pertaining to this research. Neither your name nor any personal information
will ever appear in any reports generated from this study. The physical risks associated with the
study are minimal and include those associated with blood collection. Rarely, there may be
swelling or bruising. It is also possible, but very unlikely, that there may be a risk of loss of
confidentiality of your information collected during this study. There should be no risk for
answering the questions regarding the cancer screening practices. You will not benefit from
being in this study. However, we hope that, in the future, other people might benefit from this
study because of the knowledge gained.
Privacy Act Notification: 42 U.S.C. 285a of the Public Health Service Act authorizes collection of this information. It
will be used to evaluate the role of agricultural exposures and other factors in the development of cancer, neurological
disease, birth defects and other chronic diseases. All information is voluntary and if you decide not to provide all or
any part of the requested information you will not be penalized or lose any benefits for which you otherwise qualify.
We will keep your participation in this research study confidential to the extent permitted by law.

You should not have any costs for being in this study. You will receive $100.00 for each
visit as a thank you for your participation in the main portion of the research study. You will not
receive financial incentive for answering the questions regarding cancer screening practices.
We want you to know that your participation in any activity of the Agricultural Health
Study is always voluntary. Be assured that there will be no penalties if you decide not to respond,
either to the information collection as a whole or to any particular question.
If you have any questions, concerns or do not want to participate, please contact
Deb Lande, study coordinator at 1-800-217-1954. Please specify that you are calling about
the Biomarkers of Exposures and Effects in Agriculture (BEEA) Study. If you have

Study an important and successful study of health in the agricultural community. We look
forward to speaking with you soon.

To:
Mr. [Subject's name]
From: Charles Lynch, M.D., Ph.D.
Director, Iowa Field Station

Thank you for your participation in the Biomarkers of Exposures and Effects in Agriculture
(BEEA) Study.
When you signed a consent form for this study, you indicated that you were interested in receiving
the results of the clinical tests run on your blood. A standard panel of complete blood cell count was
performed on a blood sample collected from you on [month/day/year]. As you can see from the
accompanying report, your levels of platelets (PLT), white blood cells (WBC), and red blood cells
(RBC) were all within the normal range for people in your sex and age group. Platelets are important in
assisting your blood to clot when you bleed. Mean platelet volume (MPV) is the average size of
platelets found in your blood. White blood cells are important in fighting infectious organisms. Your
red blood cells carry oxygen to your tissues and contain hemoglobin (HB) to help them perform this
task.
These red blood cells are a major constituent of your blood, and the volume of your blood occupied
by these cells is measured by the hematocrit (HCT). The mean cell volume (MCV), mean cell
hemoglobin (MCH), and mean cell hemoglobin concentration (MCHC) are also each specific to your
red blood cells. The red blood cell distribution width (RDW and RDWSD) is a measure of variability in
red blood cell size. Nucleated red blood cells (NRBC) are immature cells that normally do not enter
your blood. All of these red blood cell indices were within the normal range in your blood.
Your white blood cells consist of neutrophils (NEUT), lymphocytes (LYMPH), monocytes
(MONO), eosinophils (EOS), basophils (BASO), and immature granulocytes (IMMATURE GRAN).
Immature granulocytes are considered normal up to 2% of your WBC count. Thus, these WBC types
were all within the normal range in your blood.
Liver function tests are lab blood tests designed to provide information about the state of your liver.
The parameters measured included total protein, albumin, alkaline phosphatase, total bilirubin, direct
bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Results of these tests
were normal.
In summary, the results of your routine blood tests are all normal. If you have any questions or
concerns, please contact Dr. Charles Lynch at (319-384-1558). Please specify that you are calling about
the Biomarkers of Exposures and Effects in Agriculture (BEEA) Study.

by these cells is measured by the hematocrit (HCT). The mean cell volume (MCV), mean cell
hemoglobin (MCH), and mean cell hemoglobin concentration (MCHC) are also each specific to your
red blood cells. The red blood cell distribution width (RDW and RDWSD) is a measure of variability in
red blood cell size. Nucleated red blood cells (NRBC) are immature cells that normally do not enter
your blood. All of these red blood cell indices were within the normal range in your blood [with the
exception of the [type(s) of measure], which was/were slightly [above/below] the normal range].
Your white blood cells consist of neutrophils (NEUT), lymphocytes (LYMPH), monocytes
(MONO), eosinophils (EOS), basophils (BASO), and immature granulocytes (IMMATURE GRAN).
Immature granulocytes are considered normal up to 2% of your WBC count. Thus, these WBC types
were all within the normal range in your blood [with the exception of the [type(s) of measure], which
was/were slightly [above/below] the normal range]. [INCLUDE THE FOLLOWING IF PERFORMED:
A drop of your blood was used to make a peripheral smear. This was examined and reported to have
[report what was stated on report]].
Liver function tests are lab blood tests designed to provide information about the state of your liver.
The parameters measured included total protein, albumin, alkaline phosphatase, total bilirubin, direct
bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Results of these tests
were normal [with the exception of the [type(s) of measure], which was/were slightly [above/below] the
normal range].
In summary, the results of your routine blood tests are essentially normal. Your [types of measure]
were slightly [above/below] the normal range, but we ran many tests here and are not surprised to find
[number] out of the normal range. The normal range represents a 95% confidence interval. Thus, if you
ran 20 tests, we would expect one to be outside the normal range by chance alone. This is what I believe
has occurred with your [type of measure]. If you have any questions or concerns, please contact Dr.

To:
Mr. [Subject's name]
From: Charles Lynch, M.D., Ph.D.
Director, Iowa Field Station

Thank you for your participation in the Biomarkers of Exposures and Effects in Agriculture
(BEEA) Study.
When you signed a consent form for this study, you indicated that you were interested in receiving
the results of the clinical tests run on your blood. A standard panel of complete blood cell count was
performed on a blood sample collected from you on [month/day/year]. As you can see from the
accompanying report, your levels of platelets (PLT), white blood cells (WBC), and red blood cells
(RBC) were all within the normal range for people in your sex and age group [with the exception of the
[type(s) of measure], which was/were [above/below] the normal range]. Platelets are important in
assisting your blood to clot when you bleed. Mean platelet volume (MPV) is the average size of
platelets found in your blood. White blood cells are important in fighting infectious organisms. Your
red blood cells carry oxygen to your tissues and contain hemoglobin (HB) to help them perform this
task.
These red blood cells are a major constituent of your blood, and the volume of your blood occupied
by these cells is measured by the hematocrit (HCT). The mean cell volume (MCV), mean cell
hemoglobin (MCH), and mean cell hemoglobin concentration (MCHC) are also each specific to your

were normal [with the exception of the [type(s) of measure], which was/were [above/below] the normal
range].
{Add the following paragraph regarding lymphocyte subset test results if abnormal: Lymphocyte
subset blood tests were performed. These consist of B-cells and types of T-cells, which are important in
maintaining your health status. These were all within the normal range in your blood [with the
exception of the [type(s) of measure], which was/were [above/below] the normal range]}.

In summary, some of the results of your routine blood tests are outside of clinically-defined normal
ranges. In particular this applies to [list abnormal tests]. There are many reasons why such abnormal
tests could occur. When you enrolled in this study you indicated that you wanted any such test results
sent to:
[List name and address of Health Care Provider]
We have done this and included this letter and its accompanying results in the mailing to your health
care provider. We recommend that you consult with your health care provider to discuss your blood test
results further. If you have any questions or concerns, please contact Dr. Charles Lynch at (319-3841558). Please specify that you are calling about the Biomarkers of Exposures and Effects in

Date:
To:
Mr.
From: Charles Lynch
Director, Agricultural Health Study in Iowa
We are writing to ask you to consider participating in an important study that our group is doing
in Iowa and North Carolina, looking at the possible health effects of farming. The participants in
the study are both farmers and non-farmers.
The study, called Biomarkers of Exposure and Effect in Agriculture (BEEA), is funded by the
National Cancer Institute.
Farmers are exposed to chemicals and other substances that may affect their health. In our study
we are measuring the possible effects of those different exposures. We want to know if they
affect farmers’ risk of getting cancer and other chronic diseases.
A comparison group of non-farmers, who are similar in age and live in the same area as the
farmers in the study, can help us understand if any health changes we might see in the farmers are
related to farming or something else.
You are receiving this letter because we randomly picked your name from a list of men age 50
and older who are registered voters in your area. We hope to enroll 200 non-farmers in the next
several years in our study.
We will call you in the next couple of weeks to see if you are eligible and want to be in the study.
The call will take 10 minutes or less. If you do volunteer for the study, the caller will schedule a
home visit.
Prior to the home visit we will send you materials including a consent form, a card highlighting
key elements of the visit, a questionnaire, and a container you would use for collecting a urine
sample.
The home visit takes about 90 minutes. During the visit, a trained professional will:
•
•
•
•

Ask you about your work history, general health, and any recent use of tobacco, alcohol,
or medications;
Take a blood and a saliva sample;
Take a sample of dust from your home; and
Ask you to read and sign a consent form that describes your rights as a study participant
and confirms that you want to be in the study.

You will receive $100 as a thank you for your participation in the home visit portion of the
research study. You will not have any costs for being in this research study.
The only physical risks from participating in the study are possible swelling or bruising from the
blood draw, which occurs rarely.
Privacy Act Notification: 42 U.S.C. 285a of the Public Health Service Act authorizes collection of this information. It
will be used to evaluate the role of agricultural exposures and other factors in the development of cancer, neurological
disease, birth defects and other chronic diseases. All information is voluntary and if you decide not to provide all or
any part of the requested information you will not be penalized or lose any benefits for which you otherwise qualify. We
will keep your participation in this research study confidential to the extent permitted by law.

All of the information we collect will be used for research purposes only and will be kept strictly
confidential. Federal agencies and the University of Iowa Institutional Review Board (a
committee that reviews and approves research studies) may inspect and copy records from the
study. Your name and personal information won’t be in any reports that come out of this study.
It’s possible, although very unlikely, that the privacy of your information could be compromised.
You won’t directly benefit from being in the study. However, we hope that people will benefit in
the future from knowledge that comes from the study.
Your participation in any part of this study is voluntary. There would be no penalties for not
responding to the questionnaire or to any question.
If you have questions, concerns or don’t want to participate, please call Deb Lande, study
coordinator, at 1-800-217-1954). Please say that you are calling about the Biomarkers of
Exposures and Effects in Agriculture (BEEA) Study.
