Diabetes is associated with higher incidence of anemia. To explore causes and predisposing factors for this association, researchers used two large population-representative databases — the U.S. NHANES and the U.K. Biobank.
Notable findings were as follows:
People with diabetes were more likely than people with euglycemia to have anemia (9% vs. 3%), defined as hemoglobin <13 g/dL in men and <12 g/dL in women.
In cross-sectional analyses, people with diabetes were more likely than those without to have microcytic, normocytic, and macrocytic anemia (hazard ratios, ≈4, ≈4, and ≈2, respectively) after adjustment for age, sex, smoking, and body-mass index.
In longitudinal analyses, people with diabetes were more likely to develop iron deficiency ane…
