Association of Hemoglobin and Blood Pressure in a Chinese Community-Dwelling Population.

This study investigated the relationship between hemoglobin (Hb) level and blood pressure in a Chinese community-dwelling population with normal glucose metabolism. Hb, fasting plasma glucose, glycated Hb A1c, hepatic and renal function, lipid, electrolytes, and anthropometric parameters were measured. Hb level was found to be positively correlated with systolic (SBP; r = 0.075, p < 0.001) and diastolic (DBP; r = 0.272, p < 0.001) blood pressure in the cohort. The relationship was not affected by age, BMI, serum creatinine (Cr), and low-density lipoprotein (LDL) in both males and females. Multivariate stepwise regression showed that age (β = 0.556, p < 0.001), BMI (β = 1.107, < 0.001), Hb (β = 0.082, p < 0.001), Cr (β = -0.032, p < 0.001), and LDL (β = 1.023, p < 0.001) were independent factors for SBP, and Hb (β = 0.168, p < 0.001), BMI (β = 0.519, p = 0.001), and LDL (β = 0.331, p < 0.001) for DBP. Hb level is positively associated with both SBP and DBP in a Chinese community-dwelling population with normal glucose metabolism.
