The purpose of this study was to examine the relationship of hematologic parameters on metabolic syndrome risk factors in older women. Subjects of this study were 205 older women. Groups were divided into two groups according to the National Cholesterol ducation Program-Adult Treatment Panel III(NCEP-ATP III) criteria to confirm for metabolic syndrome : non-metabolic syndrome group(n=90) and metabolic syndrome group(n=115). Clinical variables included anthropometric variables, the serum lipid profile, and glucose level were determined. As a results, there were significant differences for WBC (p<.001), RBC(p<.01), and Hct(p<.01) in G2. WC was positively correlated with WBC(r=.205, p<.01), and SBP was positively correlated with SGOT(r=.139, p<.05), LDH(r=.189, p<.01) and RBC r=.172, p<.05).DBP was positively correlated with LDH(r=.141, p<.05), Uric acid(r=.155, p<.05), and RBC(r=.265, p< .001). TG was positively correlated with Uric acid(r=.180, p<.05), WBC(r=.346, p<.001), RBC(r=.219, p<.01) and Hct(r=.348, p<.001). FBS was positively correlated with SGOT(r=.139, p<.05), RBC(r=.173, p<.05), and WBC(r=.197, p<.01). In summary, this study suggests that hematologic parameters are to be considered when determining the metabolic syndrome symptoms.
