Summary
Glycosylated hemoglobin (HbA1) levels did not significantly change with gestational age in normal pregnancies. This study found no significant correlation between HbA1, gestational age, total hemoglobin, or glycemia.
Area of Science:
- Obstetrics and Gynecology
- Endocrinology
- Clinical Chemistry
Background:
- Gestational diabetes mellitus (GDM) screening relies on glucose monitoring.
- Glycosylated hemoglobin (HbA1) reflects long-term glycemic control.
- Understanding HbA1 trends during normal pregnancy is crucial for diagnostic interpretation.
Purpose of the Study:
- To investigate the relationship between HbA1 levels and gestational age in healthy pregnant women.
- To assess correlations between HbA1, total hemoglobin, and post-glucose load glycemia.
Main Methods:
- Prospective and transverse study design.
- Recruited 60 healthy pregnant women, categorized into 5 gestational age groups.
- Measured HbA1, total hemoglobin, and serum glucose 1 hour after a 50g oral glucose challenge test.
Main Results:
- No statistically significant differences in mean HbA1 levels were observed across the different gestational age groups.
- Correlation analysis revealed no significant association between HbA1 and gestational age.
- No significant correlation was found between HbA1, total hemoglobin, and glycemia levels.
Conclusions:
- HbA1 levels remain stable throughout normal pregnancy.
- Gestational age is not a significant factor influencing HbA1 in uncomplicated pregnancies.
- These findings support the use of HbA1 as a consistent glycemic marker irrespective of gestational age in normal pregnancies.
