Demographics: NDH and type 2 diabetes

Deprivation
BMI
1. People included: those registered at a GP practice that participated in NDA 2020-21.
2. The unlabelled ethnicity categories with very low volumes are ‘Mixed’ and ‘Other’. Ethnicity is categorised using the 2011 census categories for ethnic group.
3. The low volume ‘Unknown’ categories have not been labelled for the age and deprivation characteristic breakdowns.
4. Index of Multiple Deprivation (IMD) used to assign levels of deprivation by person’s home address where IMD 1 is for the most deprived and IMD 5 is for the least deprived areas.
5. Sum of individual percentages may not equal 100 due to rounding.
- People with NDH have very similarly distributed demographics to people with type 2 diabetes; although a greater proportion of men, and people from more deprived areas, have been diagnosed with diabetes than NDH.

- During 2020-21 healthcare services have been under increased strain as a result of the Covid-19 pandemic, and face-to-face GP appointments were limited.
- Despite these restrictions people continued to be diagnosed with NDH, and those people who were first diagnosed in 2020-21 were similar in characteristics to those diagnosed with NDH in earlier years.
- As might be expected, BMI measurements in 2020-21 were more often recorded in people with an NDH diagnosis in the current audit period.
Demographics: Year of NDH diagnosis
1. People included: with a current diagnosis of NDH at the time of the 2020-21 collection, and registered at a GP practice participating in NDA 2020-21.
2. People may have multiple dates of diagnosis recorded, and may have experienced elevated levels of blood glucose for some time before they received a non-diabetic hyperglycaemia diagnosis.
3. Figure 3 only includes earliest diagnoses made before 2021
4. Low figures for year of diagnosis in 2021 due to incomplete year in the data.
5. In NDA 2020-21, 2,091,890 people with a current diagnosis of NDH had been first diagnosed from 2010 onwards
- From 2018, the Diabetes Prevention Programme was active throughout England, coinciding with the increase in recorded NDH diagnoses in 2018.
| Year4,5 | 2010 | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 | 2021 |
| Per cent | 1.4 | 1.5 | 2.1 | 3.6 | 4.4 | 6.8 | 10.0 | 11.9 | 18.1 | 20.7 | 15.0 | 4.4 |
People continued to be diagnosed with non-diabetic hyperglycaemia in 2020 and 2021. However, the impact of Covid-19 has meant that the increasing trend in diagnoses has stopped, with fewer people being diagnosed in 2020 than in 2018.
