Information on insulin use among people with type 2 diabetes is available from the National (insulin-treated) Diabetes Register (NDR). Around 17,000 people with type 2 diabetes began insulin treatment in 2018, equating to around 4,200 cases per 100,000 registrants with type 2 diabetes not previously using insulin. According to the NDR:
- incidence rates for insulin-treated type 2 diabetes were 1.7 times as high for females as males (5,400 and 3,200 per 100,000, respectively).
- almost all cases of insulin-treated type 2 diabetes (91%) occurred among those aged 40 and over.
Note: Incidence rates of insulin-treated type 2 diabetes for Indigenous registrants have been excluded from this report, as the NDR may underestimate the number of Aboriginal and Torres Strait Islander registrants with diabetes. For more information see the ‘Methods and classifications’ section of the Australian Institute of Health and Welfare’s Incidence of insulin-treated diabetes in Australia report.
