Abstract
- Aims To investigate the usefulness of the additional measurement of HbA<subscript>1c</subscript>, compared with performing only the oral glucose tolerance test ( OGTT), in identifying participants at increased cardiometabolic risk, in an urban Chinese population. Methods All participants from the fourth visit of the population-based Hong Kong Cardiovascular Risk Factors Prevalence Study, without known diabetes, were included. All had their glycaemic status assessed by OGTT and HbA<subscript>1c</subscript>, according to American Diabetic Association 2010 criteria. Results Based on OGTT criteria alone, 3.5% of the study cohort ( N = 1300) had diabetes and 19.2% had prediabetes. Based on HbA<subscript>1c</subscript> criteria only, 6.2% had diabetes and 61.2% had prediabetes. The measurement of HbA<subscript>1c</subscript>, in addition to the OGTT, increased the proportion of participants with diabetes to 7.8% and with prediabetes to 65.3%. Subjects with prediabetes having raised HbA<subscript>1c</subscript> but normal glycaemia ( N = 600) had waist circumference, systolic blood pressure, fasting glucose, insulin resistance index ( HOMA- IR), Gutt Index and Framingham 10-year cardiovascular risk scores intermediate between those with both normal HbA<subscript>1c</subscript> and glycaemia ( N = 350), and those with impaired fasting glucose and/or impaired glucose tolerance ( N = 249; all P < 0.01). Conclusion The measurement of HbA<subscript>1c</subscript> in our population, in addition to the OGTT, results in the detection of a large number of participants with prediabetes having raised HbA<subscript>1c</subscript> but normal glycaemia who have a cardiometabolic risk profile intermediate between impaired fasting glucose and/or impaired glucose tolerance and normal participants, and would benefit from early lifestyle intervention.
