Aim: To assess HbA1c changes over time in young adults with Type 1 diabetes attending specialist transition clinic.

Method: All patients aged 15-25 years with Type 1 diabetes referred to transition clinic between August 2006 and January 2011 were studied. Patients with less than 3 subsequent clinic reviews were excluded. Data collected included baseline characteristics, frequency of clinic attendance and HbA1c at each visit. Statistical analysis was performed using SAS program.

Results: There were 101 patients with mean age of 18.6 +/- 2.3 years. Median HbA1c at initial consultation was 9.4 +/- 2.2%. Females had higher HbA1c at presentation than males (10+/- 2.3% vs. 8.9 +/- 1.9%). In the first 6 months, 86% attended at least one follow-up appointment with improvement in HbA1c to 8.6 +/- 2.2%. The greatest HbA1c improvement was in patients 21 years or older at the time of initial consultation (n=19, initial HbA1c 10.2+/- 1.8%, follow-up HbA1c 8.6+/- 1.1%), followed by 18-21 year-old group (n=38, initial HbA1c 9 +/- 2.4%, follow-up HbA1c 7.9 +/- 2.4%) and under 18 year-old group (n=44, initial HbA1c 9.4 +/- 2.1%, follow-up HbA1c 8.8 +/- 2.3%).

Summary: Statistical analysis of HbA1c changes over time will be presented.
