Key result
Poor glycemic control in type 2 diabetes is linked to ~25% lower hemoglobin levels.
Why the study?
The study aimed to compare hemoglobin levels among normal controls and type 2 diabetes patients with different HbA1c levels and to identify undetected anemia in type 2 diabetes.
Is high HbA1c associated with low hemoglobin levels in patients with Type 2 diabetes?
Cross-Sectional (n=150)
No
Is high HbA1c associated with low hemoglobin levels in patients with Type 2 diabetes?
Absolute Event Rate: 9.8% vs 13%
Higher HbA1c levels in Type 2 diabetes are associated with lower hemoglobin levels, highlighting the need to screen for anemia in poorly controlled diabetes.
No takes yet. Share an insight, caveat, or question.
HbA1c >7% was associated with lower hemoglobin in T2D; hypothesis-generating and requires prospective confirmation before screening changes.
Rashid et al. (2018) conducted a cross-sectional in Type 2 diabetes mellitus (n=150). Poor glycemic control (HbA1c > 7%) vs. Good glycemic control (HbA1c 5.6-7%) and normal controls (HbA1c ≤5.6%) was evaluated on Hemoglobin levels. Poor glycemic control (HbA1c >7%) in type 2 diabetes was associated with lower mean hemoglobin levels (9.8±1.3) compared to good control (13±0.5).
