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

摘要

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 anthro-pometric 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 (beta = 0.556, p < 0.001), BMI (beta = 1.107, <0.001), Hb (beta = 0.082, p < 0.001), Cr (beta = -0.032, p < 0.001), and LDL (beta = 1.023, p < 0.001) were independent factors for SBP, and Hb (beta = 0.168, p < 0.001), BMI ((beta = 0.519, p = 0.001), and LDL (beta = 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.
