The association between adiponectin/leptin ratio and diabetes type: the SEARCH for Diabetes in Youth Study.

We tested the association of adiponectin/leptin ratio with diabetes type after adjusting for multiple factors in 1156 youths with newly diagnosed diabetes in the SEARCH study. Although adiponectin/leptin ratio is associated with diabetes type in youth, it is due to differences in adiponectin, but not leptin levels.

Participation in pediatric epidemiologic research: the SEARCH for Diabetes in Youth Study experience.

Background: We evaluated the association of demographic and clinical characteristics with participation in an epidemiologic study of diabetes mellitus among youth.

Methods: SEARCH for Diabetes in Youth is a multicenter study of physician-diagnosed diabetes in youth under the age of 20 comprising a surveillance and a cohort component. At each center, we enumerated all prevalent cases of diabetes in 2001 (n=6266) and all incident cases between 2002 and 2004 (n=3668).
