Researchers have studied the relationship between HbA1c concentrations, cardiovascular morbidity and all-cause mortality among older insulin-treated patients with type 2 diabetes (T2D), using data from 4589 adults >65 years on insulin treatment, sourced from 532 UK General Practices. There was a a U-shaped relationship between all-cause mortality and HbA1c, with the lowest risk seen in the HbA1c range of 6.5–7.4% and marked increased in risk with HbA1c > 11%. The highest mortality risks of 31 and 40% were significantly associated with the lowest (<6.5%) and highest (11.5% and above) HbA1c categories. Individualisation of diabetes care is important and outcomes seem to be best with HbA1c levels targeted to 6.5–7.4%. More detail provided here
