South Asian people have higher levels of blood glucose than white European people, according to findings reported by researchers from the University of Leicester in the United Kingdom (Mostafa SA et al. Diabetes Care. 2012;35:1746-1748).
In the study, the investigators analyzed blood samples from 4688 white European individuals and 1352 South Asian individuals from India, Pakistan, Bangladesh, and Sri Lanka. They found that the latter had higher levels of blood glucose on 3 different measures that are used to diagnose type 2 diabetes—hemoglobin A1c, fasting plasma glucose, and 2-hour plasma glucose—even after taking into account risk factors that influence sugar levels.
