Change to inclusion of drug prescription and diabetic ketoacidosis (DKA) data for Wales
In the Interactive data visualisation published on 16 June 2022 Wales drug prescription data was not included in the diabetes diagnosis validation process. In v2.0 of the visualisation this data has been included resulting in a larger cohort used for the analysis, particularly for Wales. For further details on the diagnosis validation process see main report.
In addition, v2.0 no longer includes analysis on DKA hospital inpatient admissions for Wales. This is because it was only possible to obtain data NHS hospital admission data from hospitals in England and therefore any DKA hospital inpatient admission results for Wales would not have been representative of diabetes care in Wales.

NHS England are currently reviewing the routine production of NDA State of the Nation reports. Please note that data will still be released via dashboards and standalone data files whilst this review is being conducted.
To help inform this review we would be grateful if users can provide feedback on their use of the State of the Nation reports using the feedback survey available in the ‘Related links' section of this page.

Table 3: Adolescents and young adults with type 1 diabetes, by social deprivation*,**, England, 2017-21
| Deprivation | Type 1 Diabetes | England**** | ||
| Number | % | % of known*** | % | |
| Total | 57,060 | - | - | - |
| Most deprived | 11,595 | 20.3 | 22.4 | 20.7 |
| 2nd most deprived | 10,670 | 18.7 | 20.6 | 20.0 |
| 3rd most deprived | 10,340 | 18.1 | 20.0 | 19.3 |

| Least deprived | 9,700 | 17.0 | 18.7 | 21.8 |
| Unknown | 5,235 | 9.2 | - | - |
- A greater proportion of adolescents and young adults with type 1 diabetes lived in the most deprived areas compared to that found in the general population.
* Totals may not sum due to data suppression. See Additional Information for more details.
** Based on latest known social deprivation quintile when aged between 15 and 25 years old at start of audit year.
*** People whose social deprivation quintile is ‘Unknown’ excluded from calculation.
**** Based on linking ONS 2020 mid-year population estimates for people aged between 15 and 25 years old in England to Index of Multiple Deprivation.
Table 4: Adolescents and young adults with type 1 diabetes, by BMI status*,**,***, England, 2017-21
| BMI status | All Type 1 Diabetes | |||
| Total | Number | % | % of known**** | |
| Underweight | 47,080 | 1,705 | 3.6 | 3.7 |
| Healthy weight | 23,660 | 50.3 | 51.7 | |
| Overweight | 12,195 | 25.9 | 26.7 | |
| Obese | 8,175 | 17.4 | 17.9 | |
| Unknown | 1,345 | 2.9 | - | |
- Half (50.3%) of adolescents and young adults with type 1 diabetes were of a healthy weight according to their BMI.
- However, from the age of 18 years old the percentage of adolescents and young adults with type 1 diabetes who were living with overweight or obesity increased with age.
- Conversely the percentage of those who were of a healthy weight decreased with age.
Please note that methods for assigning BMI categorises differ between children (up to 18 years old) and adults. In adults, categories are assigned on BMI ranges. For children, their BMI is compared to reference values for children of the same sex and similar age that took part in national surveys. Therefore differences in BMI results between children and adults may be due to differences in methodology and should be treated with caution.
* Based on latest BMI when aged between 15 and 25 years old at date of BMI measurement. Only people with a BMI date are included in this analysis.
** It is not possible to include a national breakdown for comparison from the latest Health Survey for England (2019) as this source only reported a BMI breakdown for people aged 16-24 years old and the BMI categories for this age group were derived using adult methodology only.
*** Totals may not sum due to data suppression. See Additional Information for more details.
**** People whose BMI is ‘Unknown’ when aged between 15 and 25 years excluded from calculation.
