Data – England and UK
Around 113,000 (rounded off) women with Type 1 in England
Around 145,000 women with Type 1 diabetes in the UK
Calculations – England
The prevalence for all women with diabetes is 5.3 per cent (1).
Applying this to their population bases for all women of 21,399,000 (2) gives 1,134,147 women with diabetes in England.
(Note HSE give this caveat for their population bases - These population estimates are based on ONS mid-year estimates for the relevant year. Numbers aged 65+ adjusted to exclude people living in institutions (shaded cells). Figures are presented to the nearest 1,000).
Using the estimate of 10 % of people with diabetes have Type 1 gives 113,000 (rounded off) women with Type 1 in England.
Please note this does not include undiagnosed. I would recommend not trying to include undiagnosed figures as there is no gender split in the APHO figures where we get undiagnosed figures from and also most of undiagnosed is Type 2 not Type 1 so not as relevant here.
Calculations – UK
In the UK there are 2,900,000 people with diabetes diabetes (QOF). Using the 90:10 split then 10 per cent have Type 1 which is 290,000 people.
Without an estimate of gender split it is reasonable to use 50 per cent but note that there are slightly more men than women with diabetes so this is a very rough estimate.
50 per cent of 290,000 is 145,000, therefore there are roughly 145,000 women with Type 1 diabetes in the UK.
Note
England figures are a bit more accurate, but we should be clear for both figures that these are rough estimates.
