The Claim
In non-diabetic pregnant women, higher hemoglobin levels are associated with higher HbA1c values, with a statistically significant but weak positive correlation (r = 0.174, P = 0.037), indicating that red blood cell mass may influence HbA1c independently of blood glucose levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In pregnant women without diabetes, having more hemoglobin in the blood is linked to slightly higher HbA1c levels — a marker usually tied to blood sugar — suggesting that blood cell levels might affect this test even if sugar isn't high.
See the scientific wording
In non-diabetic pregnant women, higher hemoglobin levels are associated with higher HbA1c values, with a statistically significant but weak positive correlation (r = 0.174, P = 0.037), suggesting that red blood cell mass may influence HbA1c independently of glycemia.
What the research says
1 studyStudy: Glycated hemoglobin and red blood cell indices in non-diabetic pregnant women
The study found that in pregnant women without diabetes, those with higher hemoglobin levels also had higher HbA1c levels, just like the claim says. This suggests that blood cell factors, not just blood sugar, can affect HbA1c.
