Abstract

Objective The current study examined how the pattern of systemic inflammation in the decades leading up to late-life relates to depression symptoms in older adults.Methods Within the Atherosclerosis Risk in Communities Study, we measured high-sensitivity C-reactive protein (CRP), a nonspecific marker of systemic inflammation, at three visits: 21 years and 14 years before, and concurrent with the assessment of depression symptoms, defined using the 11-item Center for Epidemiologic Studies Depression (CESD) scale. We categorized participants into one of four groups based on their 21-year longitudinal pattern of elevated (≥3 mg/L) versus low (<3 mg/L) CRP (stable low; unstable low; unstable elevated; stable elevated). Analyses excluded participants with suspected depression during midlife.Results A total of 4,614 participants were included (age at CESD assessment: 75.5 [SD: 5.1]; 59% female; follow-up time: 20.7 years [SD: 1.0]). Compared to participants who maintained low CRP levels (stable low), participants who had elevated CRP at two of three visits (unstable elevated; ß = 0.09; 95% confidence interval [CI]: 0.02, 0.17) and participants who maintained elevated CRP at all three visits (stable elevated; ß = 0.13; 95% CI: 0.05, 0.21) had greater depression symptoms as older adults, after adjusting for confounders. After excluding participants with late-life cognitive impairment, only participants with stable elevated CRP demonstrated significantly greater late-life depression symptoms. In a secondary analysis, stable elevated CRP was associated with increased risk for clinically significant late-life depression symptoms.Conclusion Chronic or repeated inflammation in the decades leading up to older adulthood is associated with late-life depression, even in the context of normal cognition.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Stable elevated CRP levels were associated with an increased risk for late-life depressive symptomatology.

    “Moreover, stable elevated CRP levels were associated with an increased risk for late-life depressive symptomatology [94].”

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.
