OBJECTIVES: To evaluate relationships between white blood cell (WBC) count and @entity650 ( @entity650 ) and prevalent frailty. DESIGN: Cross-sectional study. SETTING: Two population-based studies, the @entity1 's Health and Aging Studies (WHAS) I and II, Baltimore, Maryland. @entity1 : Five hundred fifty-eight @entity1 aged 65 to 101 from WHAS I and 548 @entity1 aged 70 to 79 from the merged WHAS I and II cohorts. MEASUREMENTS: Frailty was determined using validated screening criteria. WBC counts and @entity650 levels were measured using standard laboratory methods. Odds ratios (ORs) for frailty were evaluated across tertiles of baseline WBC counts and @entity650 levels, adjusting for age, race, education, body mass index, and smoking status. RESULTS: In WHAS I, those in the top tertile of WBC count and @entity650 had ORs of 4.25 (95% confidence interval (CI)=1.89-9.58) and 3.98 (95% CI=1.76-9.00), respectively, for frailty (both P<.001). In the combined models, @entity1 in the top tertile of WBC count had an OR of 3.15 (95% CI=1.34-7.41), adjusting for @entity650 (P<.01), and those in the top tertile of @entity650 had an OR of 2.81 (95% CI=1.19-6.64), adjusting for WBC count (P<.05). Furthermore, @entity1 in the top tertiles of WBC count and @entity650 had an OR of 9.85 (95% CI=3.04-31.99), and those in the middle/top tertiles had an OR of 5.40 (95% CI=1.83-15.92) (P<.001, trend test) for frailty. These results were validated in the merged WHAS I and II. CONCLUSION: Higher WBC counts and @entity650 levels were independently associated with prevalent frailty in community-dwelling older @entity1 .
