Abstract

Glycated haemoglobin (HbA(1c)) has been proposed as an alternative to the oral glucose tolerance test for diagnosing diabetes. We compared the cardiovascular risk profile of individuals identified by these two alternative methods. We assessed the prevalence of cardiovascular risk factors in individuals with undiagnosed diabetes according to the World Health Organization classification or by the newly proposed HbA(1c) level >or= 6.5% among 6258 participants of the Danish Inter99 study. Receiver operating curve analysis assessed the ability of fasting: 2-h plasma glucose and HbA(1c) to distinguish between individuals at high and low risk of ischemic heart disease, predicted by the PRECARD program. Prevalence of undiagnosed diabetes was 4.1% [95% confidence interval (CI) 3.7-4.7%] by the current oral glucose tolerance test definition, whereas 6.6% (95% CI 6.0-7.2%) had diabetes by HbA(1c) levels. HbA(1c)-defined individuals were relatively older with higher proportions of men, smokers, lipid abnormalities and macro-albuminuria, but they were leaner and had lower blood pressure. HbA(1c) was better than fasting- and 2-h plasma glucose at distinguishing between individuals of high and low predicted risk of ischaemic heart disease; ho...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
