Prevalence of Diabetes Mellitus Associated Chronic Kidney Disease in Ethnically Diverse Backgrounds in Western Sydney

Background: Past research has demonstrated that ethnically diverse backgrounds have a greater risk of Diabetes Mellitus and/or Chronic Kidney Disease (CKD), which both contribute significantly to the disease burden placed on the Australian Healthcare system. The purpose of this study was to investigate the differences in DM associated CKD between ethnicities in Western Sydney, NSW Australia, which is known to be an ethnically diverse geographical region.Method: Using data from Blacktown and Mt Druitt Hospitals and a retrospective approach, individuals with diabetes and CKD were identified based on HbA1c and eGFR results. Using univariate analysis and past research, a logistic regression modelling was carried out on the data to identify relationships between ethnicity and DM associated CKD.Results: Out of 73,001 observations, 24,009 individuals were included in the analysis with 3,934 individuals with HbA1c consistent with diabetes and kidney function at eGFR at Stage 2 and above. 47% were female and 53% were males and the median age was 76 ± 12 years. Using a forward-method model building process, ethnicity was compared to a reference of Caucasian. The model showed that Pacific Islanders have the most risk (OR: 5.63, p Conclusion: The results show a clear difference in risk between ethnicities in DM associated CKD and its associated risk factors. These differences should be accounted for when considering interventions for at risk communities.
