In 66.6 per cent of the records from people with Type 2 diabetes but only 28.6 per cent of records from people with Type 1 diabetes was HbA1c ≤ 7.5 per cent (NICE recommended). Thus, overall, approximately 40 per cent of people with diabetes have a high risk (for future
complications) HbA1c of > 7.5 per cent.
Furthermore, 33.6 per cent of people with Type 1 diabetes and 14.3 per cent of people with Type 2 diabetes have a very high risk HbA1c value of > 10 per cent. These overall results
are very similar to those found in 2006-2007 and 2007-2008.
However, there are appreciable subgroup differences in the rates of achieving target glucose control
For Type 1 diabetes a target HbA1c of ≤ 7.5 per cent was
more likely with:
– older age;
– male gender;
– higher weight (27.8 per cent with BMI between 18.5 and 25 vs 35.9 per cent with BMI > 40);
– and least social deprivation (25.7 per cent Q1 vs 19.9 per cent Q5)
For Type 2 diabetes a target HbA1c of ≤ 7.5 per cent was associated with:
– older age;
– female gender;
– white ethnic group (White 70.4 per cent, Asian 58.5 per cent, Black 62.5 per cent, Other 58.7 per cent);
– shorter duration of diabetes (duration < 9 years over 60 per cent, 10-19 years ~ 50 per cent,
20+ years ~ 40 per cent);
– lower weight (76.1 per cent with BMI between 18.5 and 25 vs 60.7 per cent BMI > 40);
– and lower social deprivation (64.15 per cent Q1 vs 57.29 per cent Q5)
