Over 5% of men and 4% of women in England have diagnosed diabetes.
The Quality and Outcomes Framework (QOF) provides information on the registrations for diabetes. In 2006, the overall prevalence of diabetes in Great Britain was estimated to be 4%.
Not all diabetes is diagnosed. The Health Survey for England 2003 suggests that 3.1% of men and 1.5% of women aged 35 and over have undiagnosed diabetes.
For both men and women, the proportion of people with diabetes increases with age. The Health Survey for England 2006 suggests that around 1% of men aged 16 to 34 years have diagnosed diabetes compared with 13.5% of those aged 75 and over. This pattern is similar in women, although rates are slightly lower at most ages than for men.
