Inflammation and Frailty in Older Women
Abstract
OBJECTIVES: To evaluate relationships between white blood cell (WBC) count and interleukin‐6 (IL‐6) and prevalent frailty. DESIGN: Cross‐sectional study. SETTING: Two population‐based studies, the Women's Health and Aging Studies (WHAS) I and II, Baltimore, Maryland. PARTICIPANTS: Five hundred fifty‐eight women aged 65 to 101 from WHAS I and 548 women aged 70 to 79 from the merged WHAS I and II cohorts. MEASUREMENTS: Frailty was determined using validated screening criteria. WBC counts and IL‐6 levels were measured using standard laboratory methods. Odds ratios (ORs) for frailty were evaluated across tertiles of baseline WBC counts and IL‐6 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 IL‐6 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, participants in the top tertile of WBC count had an OR of 3.15 (95% CI=1.34–7.41), adjusting for IL‐6 ( P< .01), and those in the top tertile of IL‐6 had an OR of 2.81 (95% CI=1.19–6.64), adjusting for WBC count ( P< .05). Furthermore, participants in the top tertiles of WBC count and IL‐6 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 IL‐6 levels were independently associated with prevalent frailty in community‐dwelling older women.

In the citing paper
“A range of inflammatory cytokines have been independently associated with frailty including interleukin-6 (IL-6), C-reactive protein (CRP), tumour necrosis factor-α (TNFα) and CXC chemokine ligand-10 (CXCL-10), a potent pro-inflammatory mediator (52, 54-58).”
From Frailty in elderly people (2013) · cites this paper as [55]
In the citing paper
“There is evidence that inflammation has a key role in the pathophysiology of frailty through an abnormal, low-grade inflammatory response that is hyper-responsive to stimuli and that persists for a prolonged period following removal of the initial inflammatory stimulus (19, 52-57).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
