A comparison of HbA_1c concentration in people with Type 2 diabetes at sea level and high altitude in China: an observational study

Haemoglobin A1c interpretation; more than mean blood glucose to be considered

“…A number of data analyses have been undertaken, most recently looking at the effect of iron deficiency anaemia and ethnicity , and reporting non‐glycaemic effects on HbA 1c . This issue of Diabetic Medicine contains two articles studying the effects of altitude on the measured HbA 1c , an interesting variable not previously considered, even though altitude is commonly known to affect the haemoglobin concentration. The first article looked at data from 3613 Peruvians in two longitudinal studies, comparing biochemical data on people at sea level with that on people from high altitude; all participants had no previous diagnosis of diabetes.…”
