SEARCH Phase 3 Objectives 
Five of the original six SEARCH 1 and 2 centers were funded to participate in SEARCH3: 
(Carolinas, Ohio, Colorado, California, and Washington).  The objectives of SEARCH Phase 3 
include a registry component and a cohort component.  Each component will be performed at all 
five clinical centers.  In SEARCH Phase 3, many of the measurements which were collected 
during SEARCH Phases 1 and 2 will continue to be collected; additionally, there will be unique 
measurements collected for each component of SEARCH Phase 3. 
Registry Study 
The SEARCH for Diabetes in Youth Registry Study will continue to ascertain newly diagnosed 
incident diabetes cases in youth age < 20 years across five geographically dispersed Study 
Centers in order to accomplish the Specific Aims shown below.  The study will continue to 
identify incident cases from September 30, 2010 through September 29, 2015, and will 
periodically re-ascertain cases from earlier years. 
Aim 1:  To continue to ascertain newly diagnosed (2010 - 2014) incident diabetes cases in 
youth age < 20 years in order to assess temporal trends in diabetes incidence and temporal 
trends in presentation of diabetes for the period 2002-2014, by age, sex, race/ethnicity, and 
diabetes type. 
Specific characteristics to be examined are: age at onset of diabetes, markers of disease 
severity (diabetic ketoacidosis, residual insulin secretion, HbA
1c
), immunogenetic markers 
(diabetes autoantibodies, HLA risk genotypes), markers of insulin sensitivity (insulin 
sensitivity score, waist circumference, body mass index), cardiovascular risk factors (lipid 
profile, blood pressure, microalbuminuria). 
Aim 2:  To provide consultation and support to inform the development of low-cost 
sustainable public health surveillance systems of childhood diabetes in the U.S., with a focus 
on challenges in ascertainment of cases with T2D and cases among older youth (ages 15 
years or older) with any form of non-gestational diabetes.

Aim 3:  Assess total and cause-specific mortality among 2002-2008 incident cases for the 
period from the date of diabetes diagnosis through December 31, 2010.   
Cohort Study 
An in-person research visit with SEARCH participants incident in 2002 or later, with a duration 
of diabetes > 5 years, and with data from a baseline study visit (expec
