Overview

There are marked ethnic disparities in the prevalence of prediabetes and diabetes in Australian primary care, highlighting the need for ethnicity-specific screening and prevention strategies.

Key Points

  • This study aims to investigate ethnic differences in the prevalence of prediabetes and diabetes and their associated risk factors in Australia.
  • Analyzed electronic health records of 60,887 adults from the General Practitioner Research Network (2014-2024) database.
  • Classified glycaemic status using ADA criteria based on fasting plasma glucose, HbA1c, or 2-hour oral glucose tolerance test.
  • Estimated adjusted odds ratios for prediabetes and diabetes using logistic regression, controlling for age, sex, and body mass index.
  • Prediabetes prevalence varied from 12.2% among Hispanics to 23.7% among South & Central Asians.
  • Diabetes prevalence was highest among Pacific Peoples (11.6%) and lowest among Hispanics (5.8%).
  • Middle Eastern and North Africans had 3.16 times higher adjusted odds of diabetes compared to Europeans (AOR 3.16, 1.94-5.05).
