ARTICLE HIGHLIGHTS
Research background

The relationship between hemoglobin (Hb) and hemoglobin A1c (HbA1c) remains unclear.

Research motivation

To elucidate the relationship between Hb and HbA1c in a nondiabetic population aged ≥ 16 years in America.

Research objectives

To elucidate the relationship between Hb and HbA1c.

Research methods

The relationship was estimated using a multivariate regression.

Research results

Hb levels are negatively correlated with HbA1c.

Research conclusions

Normal Hb levels are negatively correlated with HbA1c in nondiabetic Americans aged ≥ 16 years.

Research perspectives

From a clinical point of view, HbA1c decreases by 0.08% for every 1 g/dL increase in Hb.
