Registry of people with diabetes in India with Young age at Onset (2006-2011)

YDR is a multicentric clinic based registry of youth onset diabetes operating through Regional Collaborating Centres (RCC) and their interacting Reporting Centres (RC) across India. During phase-I (1 January 2000 to 31 July 2011) of the YDR, 8 RCCs and 205 RCs participated in the data collection. The RCs ranged from single physician clinics to multi-specialty private hospitals to public funded tertiary care facilities. Patients reporting on or after 1 January 2000 at the RCs were enrolled in the registry if they satisfied the inclusion criteria, namely, age at diagnosis ≤25 years with fasting plasma glucose ≥126 mg/dL and/or 2 hours postload plasma glucose ≥200 mg/dL.
