We found that among UK residents in Wolverhampton, South Asians have higher haemoglobin A1c values than white people whether glucose intolerance is impaired or not.3 4 But they had lower (impaired glucose tolerance) or similar (normal glucose tolerance) fasting glucose concentrations and similar postprandial glucose concentrations during a 75 g oral glucose tolerance test. The South Asians were also younger, although increasing age is associated with higher haemoglobin A1c concentration.5
