Introduction Type 2 diabetes is more prevalent among Aboriginal and Torres Strait Islander Peoples, especially those living in rural than urban areas. However, little is known about how diabetes is managed in different settings. Objective To investigate differences in the prevalence of diabetes and the prescription of antidiabetic medications for Aboriginal and/or Torres Strait Islander Peoples living in urban or rural Australia. Design Cross‐sectional study using de‐identified electronic medical records of 29,429 Aboriginal and/or Torres Strait Islander adults (60.4% females; mean age 45.2 ± 17.3 years) regularly attending 528 ‘mainstream’ Australian general practices (MedicineInsight) in 2018. Findings The prevalence of diabetes was 16.0%, and it was more frequent among those living in rural areas (22.0; 95% CI 19.3–24.4) than inner regional (17.6%; 95% CI 16.0–19.2) or major cities (15.8%; 95% CI 14.7–17.0; p < 0.001). The highest prevalence of diabetes was for males living in rural settings (25.0%). Of those with diabetes, 71.6% (95% CI 69.0–74.0) were prescribed antidiabetics, with a similar frequency in urban and rural areas ( p = 0.291). After adjustment for sociodemographics, the only difference in diabetes management was a higher prescription of sulfonylureas in rural areas than in major cities (OR 1.39; 1.07–1.80). Discussion The prevalence of diabetes was similar to other national data, although we found it was more frequent amongst Aboriginal and/or Torres Strait Islander males, especially those from rural areas. Conclusion Despite current recommendations, one‐in‐four Indigenous Australians with diabetes were not prescribed antidiabetics. The clinical significance of more frequent prescriptions of sulfonylureas in rural locations remains unclear.
