To the Editor: This retrospective population‐based study aimed to determine the incidence of type 2 diabetes from 2012 to 2019 in Western Australian youth aged under 16 years, and to examine temporal trends between 2000 and 2019, using data from the Western Australian Children’s Diabetes Database (WACDD).1 The data extracted for eligible patients diagnosed with type 2 diabetes, according to standard criteria,2 included diagnosis year, age, sex and self‐reported Aboriginal or Torres Strait Islander status. Poisson regression was used to determine incidence rates and trends by calendar year, sex, and Aboriginal or Torres Strait Islander status. This study received ethics approval from the Western Australian Child and Adolescent Health Service Human Research Ethics Committee (RGS0000002386).
