Both men and women with lower hemoglobin had significantly higher HbA1c at a given fasting glucose level, and this result was consistent across the fasting glucose quintiles within the non‐diabetic range. Women had a lower mean hemoglobin value compared with men, and women had higher HbA1c levels at a given fasting glucose level consistently across the fasting glucose deciles. There was also a gender‐specific association between age and HbA1c (<italic>P</italic> < 0.001 for interaction).</p> </sec> <sec id="jdi12123-sec-0004" sec-type="section"> <title>Conclusions</title> <p>HbA1c values were affected by hemoglobin level and gender in non‐anemic Koreans.
