This model, produced by Public Health England and the National Cardiovascular Intelligence Network, estimates the total number of adults with both Type 1 and Type 2 diabetes in England. The data shows that whilst 3.8 million people are estimated to have diabetes, approximately 90 per cent of diabetes cases are Type 2.
To help visualise local diabetes prevelance over time and in comparison with other areas, using the data published by PHE this tool produced by the LGA allows you to view local authority prevelance data.
Diabetes refers to a condition where the amount of glucose in your blood is too high. There are two main types of diabetes: type 1 diabetes and type 2 diabetes. Type 1 diabetes develops when the body is unable to produce any insulin.Type 2 diabetes develops when the body is unable to produce enough insulin or the body’s cells don’t react to insulin. It is estimated that approximately 90% of diabetes is type 2. The diabetes prevalence model provides estimates of total (diagnosed and undiagnosed) diabetes prevalence for people aged 16 years and over in England. It does not make a distinction between the type of diabetes.
The model was developed using data from the latest three years of Health Surveys for England (HSE), 2012, 2013 and 2014. The estimates take into account the age, sex, and ethnic group distribution, as well as deprivation of the area. Estimates are created using resident populations and GP registered populations. The 2014 Office for National Statistics (ONS) population projections were used for the resident population based estimates. The numbers of patients registered by GP practice in April 2015 were used for the registered population based estimates. Full details of the model methodology can be found in the technical document on the National Cardiovascular Intelligence Network (NCVIN) website.
Diabetes prevalence estimates have been produced for local authorities, clinical commissioning groups (CCG) and for the whole of England and are provided for 2015, 2016, 2017, 2018, 2019, 2020, 2025, 2030 and 2035.
