Influence of iron deficiency anemia on glycated hemoglobin levels in non-diabetic Saudi women

Abstract

Objective Studies of patients with iron deficiency anemia (IDA) have shown a relationship between high glycated hemoglobin (HbA1c) and low hemoglobin (Hb) concentration. The present study was conducted to determine the influence of IDA on HbA1c in non-diabetic women. Methods Fifty-nine Saudi women (20 to 50 years old) were enrolled and categorized into groups according to their circulating hemoglobin concentration: Non-IDA (Hb ≥7.45 mmol/L; n = 38) and IDA (Hb ≤7.44 mmol/L; n = 21). The IDA group was further subdivided according to the severity of the IDA, as follows: mild (Hb 6.83 to 7.44 mmol/L; n = 9) and moderate–severe (Hb <6.83 mol/L; n = 12). HbA1c, Hb, ferritin, fasting blood glucose, and red blood cell (RBC) count were measured in each participant. Results HbA1c did not significantly differ between the groups, but the absolute HbA1c level was significantly lower in the mild and moderate–severe anemia groups than the non-anemic group, and was positively associated with Hb, ferritin, and RBC count. In addition, the HbA1c level was inversely associated with the Hb concentration. Conclusions HbA1c is significantly associated with parameters related to IDA in non-diabetic Saudi women. Therefore, assessment of IDA-related parameters is recommended prior to making a diagnosis of diabetes.

The Combination Clinical Value of Plasma Brain Natriuretic Peptide and Serum HbAlc in the Diagnosis of Chronic Pulmonary Heart Disease

“…It has the advantages of simple operation and wide application. However, with the significant development of human diseases and the improvement of medical technology, the effect of traditional electrocardiogram still needs to improve [ 26 – 29 ]. ECG vector chart can effectively record the size and direction of electrical signals generated by the heart, effectively eliminate all kinds of heart diseases except arrhythmia, and truly and effectively describe the stereoscopic image of heart activity.…”

Exploring the Impact of Iron Deficiency Anaemia on Glycated Haemoglobin A1c Levels in Pregnant and Non-Pregnant Women: A Systematic Review

“…Many relationship between IDA and HbA1c is a subject of research, with several studies suggesting that IDA is associated with higher HbA1c levels in diabetic and nondiabetic males and non-pregnant women, [31][32][33][34][35][36][37][38][39][40] while others propose a contrary association. [41][42][43][44][45] The literature contains different systematic reviews and meta-analyses that discuss the correlation between IDA and HbA1c levels in this group. [46][47][48][49][50] However, a few studies have discussed their correlation in pregnant women with IDA.…”

Age and sex trend differences in hemoglobin levels in China: a cross-sectional study

“…It was interesting that the coefficient of the 50 ~ 60 years old section showed no statistical significance in women. Hemoglobin concentrations in postmenopausal women usually increase moderately, and it could irreversibly bind with glucose to form glycosylated hemoglobin when blood glucose levels increased [ 30 , 31 ]. Chronic hyperglycemia causes excessive production or accumulation of reactive oxygen species (ROS), and directly activates calcium-sensitive K + channels.…”
