STUDY OBJECTIVE
• To evaluate long-term clinical outcomes and survival in young-onset type 2 diabetes (T2DM) compared with type 1 diabetes (T1DM) with a similar age of onset
Constantino M. I. et al. Diabetes Care 2013;36:3863-3869
STUDY DESIGN AND METHODS
• Records from the Royal Prince Alfred Hospital Diabetes Clinical Database were matched with the Australian National Death Index
• Mortality outcomes for all subjects until June 2011 were established
• Clinical and mortality outcomes in 354 patients with T2DM, age of onset between 15 and 30 years (T2DM15–30), were compared with T1DM
• Primary comparison was with 470 patients with T1DM with a similar age of onset (T1DM15–30) to minimize the confounding effect of age on outcome
Constantino M. I. et al. Diabetes Care 2013;36:3863-3869
RESULTS
• Median observation period was 21.4 (interquartile range 14–30.7) and 23.4
• (15.7–32.4) years for the T2DM and T1DM cohorts, respectively
• 71 of 824 patients (8.6%) died
• A significant mortality excess was noted in T2DM15–30 with an increased hazard for death
Constantino M. I. et al. Diabetes Care 2013;36:3863-3869
RESULTS
• Death for T2DM15–30 occurred after a significantly shorter disease duration and at a relatively young age
• There were more cardiovascular deaths in T2DM15–30
• Albuminuria and less favorable cardiovascular risk factors were greater in T2DM15–30
• Neuropathy scores and macrovascular complications were also increased in T2DM15–30

CONCLUSIONS
• Compared with T1DM, young-onset T2DM is the more lethal phenotype of diabetes and is associated with:
• Greater mortality• More diabetes complications• Unfavorable cardiovascular disease risk factors
