Potential Benefits of the Proposed Research to the Participants and Others
There are no direct benefits to study participants. In some cases, however, test results
may help to more clearly define the type of diabetes an individual may have. Test results
may also identify the presence or increased risk for some of the complications associated
with diabetes. If the participant gives their consent, test results will be shared with their
healthcare provider. In some cases, based on SEARCH test results, the healthcare
provider may choose to make changes to the treatment plan.
Participation in this study may also result in potential benefits to society. This is a large,
multi-center study that will be well-represented by young people from a variety of
racial/ethnic backgrounds. The information obtained in this study will help clinicians to
better understand the prevalence and incidence of childhood diabetes, the characteristics
of various types of diabetes, the frequency of the occurrence of complications associated
with diabetes, and the impact diabetes has on the lives of these young people. This
information will also be important in the planning of the distribution of medical and
financial resources for the care of young people with diabetes in the future.
Potential risks to study participants are minimal and reasonable in relation to the
anticipated benefits to society from the knowledge that will be gained from this study.

Importance of the Knowledge to be Gained
Diabetes is the third most common chronic disease of childhood and adolescence. In the
past, childhood diabetes was thought to consist almost exclusively of Type 1 diabetes.
Over the past two decades, however, an increasing number of cases of Type 2 diabetes
have been reported within this population. Overall, the total number of diabetes cases
affecting people less than 20 years of age that are developing diabetes seems to be
increasing over time.
This is a large, multi-center study that will be well-represented by youth from a variety of
racial/ethnic backgrounds. The information obtained in this study will help clinicians and
researchers better understand the prevalence and incidence of childhood diabetes, the
characteristics of persons with various types of diabetes, the frequency of the occurrence
of complications associated with diabetes, the impact diabetes has on the lives of these
young people, and the factors that relate to high quality diabetes care for children/youth.
This information will also be important in the planning of the distribution of medical and
financial resources for the care of young people with diabetes in the future.
Potential risks to study participants are minimal and reasonable in relation to the
importance of the knowledge that is expected to be gained from this study.

Data and Safety Monitoring Plan
Even though this study is not a clinical trial, an internal Protocol Oversight Committee
(POC) has been established for SEARCH to: 1) oversee personnel training and
certification procedures to assure consistency of measurements among all SEARCH
centers; 2) review the quality of the data collected, as well as the laboratory results; and
3) review any adverse events that might occur. In addition, an external monitor reviews
the activities of the studies, based on reports from the POC. The external monitor will
provide interim and annual safety reports to the Director of the Coordinating Center and
the POC. The interim reports will be quarterly and will clarify issues of interest for the
monitor. They will be interactive in nature. Issues raised by the monitor will be queried
by the POC to the relevant clinics; and clinic responses will clarify handling of issues,
with copies of event reports signed by the Principal Investigator sent to the POC, the
Coordinating Center, and to the monitor.
The annual report will summarize the findings of the monitor over the year period, will
be on academic letterhead, and will be dated and signed by the monitor. It will include
comments about event rates, types of events and relatedness to the study, and other issues
which the monitor thinks transmit the safety profile of the study to the Principal
Investigators, and to local IRB's.

REPOSITORY
Testing related to diabetes is limited to basic testing as mentioned in Section 6A and 6B.
These tests enable medical personnel to evaluate the diabetes status of participants.
SEARCH investigators recognize that new information may become available during or
following the collection of data that may make it desirable to perform additional biochemical
tests on participants who are no longer available for further data collection.
Since new genetic markers continue to be identified, markers currently available will be
enhanced by those developed in the future. These markers will add to the basic knowledge
of diabetes. Genetic analyses not currently funded in the SEARCH study, may be more
efficiently performed on select, well-characterized group(s) of participants. Thus, genetic
material will be available to answer specific questions.

Sample Types
Two types of samples to be collected and stored are:
a)
Biochemical: serum, plasma, and/or urine
b)
Samples for DNA extraction (buffy coat)
Genetic analyses may be done on the SEARCH population to identify specific markers
related to certain types of diabetes. Genetic markers may add to the understanding of
diabetes.

Consent for Sample Storage
The consent process will allow study participants to consent or refuse to have samples
stored in the repository laboratory. Consent will be structured in such a way that
