Comparison of comorbidities in patients with pre-diabetes to those with diabetes mellitus type 2.

A cross sectional study performed on 309 pre-diabetes and 309 type 2 diabetes patients, selected from General Practices in Cork. The prevalence of complications was calculated and the data analysed to determine is there a statistically significant difference in prevalence of complications. The prevalence of co-morbidities in the type 2 diabetic group are Ischaemic Heart Disease 55 (17.8%), Chronic Kidney Disease 17 (5.5%), cerebrovascular disease 16 (5.2%), peripheral vascular disease 40 (12.9%), eye disease 20 (6.5%), peripheral neuropathy 27 (8.7%) and autonomic neuropathy 11 (3.6%). The prevalence of co-morbidities in the pre-diabetic group are Ischaemic Heart Disease 64 (20.6%), Chronic Kidney Disease 12 (3.9%), cerebrovascular disease 11 (3.5%), PVD 24 (7.7%), eye disease 1 (0.3%), peripheral neuropathy 8 (2.6%) and autonomic neuropathy 17 (5.5%). The prevalence of many of the co-morbidities assessed is statistically the same in pre-diabetes patients with only peripheral vascular disease, eye disease and cerebrovascular disease having a statistically significant higher prevalence in type 2 diabetes.
