This retrospective cohort study aims to characterise the prevalence of Type 2 diabetes between 1991 and 2013 in the UK and determine whether corresponding glucose control and survival had changed in the diabetic population during this period.
For this retrospective cohort study, people diagnosed with Type 2 diabetes between 1991 and 2013 were identified from the Clinical Practice Research Datalink (CPRD) and the annual point prevalence calculated. Mean HbA1c by year was estimated.
The prevalence of diagnosed Type 2 diabetes trebled in the UK between 1991 and 2013. Improved survival in people with diagnosed Type 2 diabetes is likely to account, at least in part, for the increase in prevalence observed.
