Abstract

Although intermittent increases in inflammation are critical for survival during physical injury and infection, recent research has revealed that certain social, environmental and lifestyle factors can promote systemic chronic inflammation (SCI) that can, in turn, lead to several diseases that collectively represent the leading causes of disability and mortality worldwide, such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease and autoimmune and neurodegenerative disorders. In the present Perspective we describe the multi-level mechanisms underlying SCI and several risk factors that promote this health-damaging phenotype, including infections, physical inactivity, poor diet, environmental and industrial toxicants and psychological stress. Furthermore, we suggest potential strategies for advancing the early diagnosis, prevention and treatment of SCI.

    “The fact that differences exist in the extent to which older adults exhibit SCI52,64 is thought to be indicative of inter-individual differences in exposure to these and other related pro-inflammatory factors, although studies documenting within-person associations between these risk factors and SCI are limited.”

    Early-life psychological stress-from abuse, neglect, maltreatment, bullying or low socioeconomic conditions-can intensify neural threat responses, increase inflammatory activity, change immune competence, and produce SCI across the lifespan.

    “exposure to psychological stress early in life—for example, in the form of abuse, neglect, maltreatment, bullying or living in a low socioeconomic environment—can heighten neural responses to threat that can upregulate inflammatory activity170, alter immuno-competence and lead to SCI throughout the lifecycle27,169”

    There are currently no standard biomarkers for indicating the presence of health-damaging chronic inflammation.

    “there are presently no standard biomarkers for indicating the presence of health-damaging chronic inflammation.”
  • The authors state this as an assumption.

    An evolutionary mismatch between human physiology and industrialized lifestyles is a major cause of systemic chronic inflammation.

    “This is believed to have created an evolutionary mismatch in humans—characterized by an increasing separation from their ecological niche—and this mismatch, in turn, has been hypothesized to be a major cause of SCI65,66,82,89,92.”
  • The authors state this as an assumption.

    Maternal inflammation during pregnancy passes an inflammatory code through epigenetic modifications to offspring, leading to elevated SCI risk in childhood and adulthood and intergenerational transmission of risk.

    “In this model (Fig. 2), SCI and disease risk are hypothesized to be perpetuated transgenerationally.”

    A majority of older adults experience down-regulation of immune response components, leading to increased susceptibility to viral infections and weakened vaccine responses.

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

  • Reductions in CRP levels can be achieved by lifestyle interventions that promote better overall health.

    “Reductions in CRP levels can be instead achieved by lifestyle interventions that promote better overall health (Furman et al., 2019).”

    From Treatment of periodontitis and <scp>C</scp> ‐reactive protein: A systematic review and meta‐analysis of randomized clinical trials (2023) · cites this paper as Furman et al., 2019

    The Physical activity section says muscle contraction can reduce systemic inflammation and links low activity to higher CRP levels. That supports physical activity as a route to lower CRP, but it does not directly report CRP reductions from a lifestyle intervention; the Future directions section says studies showing reduced chronic inflammation after targeting lifestyle factors remain limited. (LLM, conf=0.81)

    Experimental — accuracy not yet measured
  • Systemic inflammation as assessed by high CRP levels raises the future risk of chronic diseases and their complications like diabetes, renal and CVDs.

    “Systemic inflammation as assessed by high CRP levels raises the future risk of chronic diseases and their complications like diabetes, renal and CVDs (Libby et al., 2018; Furman et al., 2019).”

    From Treatment of periodontitis and <scp>C</scp> ‐reactive protein: A systematic review and meta‐analysis of randomized clinical trials (2023) · cites this paper as Furman et al., 2019

    The section “Systemic chronic inflammation and non-communicable disease risk” links systemic chronic inflammation to type 2 diabetes, chronic kidney disease and CVD, and reports that elevated CRP predicts cardiovascular events. It does not establish that high CRP predicts future diabetes or kidney disease; it also describes the CRP–CVD finding as an association rather than proof that CRP raises risk. (LLM, conf=0.86)

  • Inflammation promotes oxidation through inflammatory mediators.

    “At the same time, inflammation promotes oxidation through inflammatory mediators.205,206”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [206]

    The ‘Systemic chronic inflammation and non-communicable disease risk’ section says systemic chronic inflammation can damage tissues by inducing oxidative stress. That supports the inflammation-to-oxidation link, but the passage does not say that inflammatory mediators are the mechanism. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Periodontitis is a source of low-grade chronic systemic inflammation via haematogenous dissemination of periodontal bacteria or spillover of inflammatory mediators, contributing to systemic inflammatory burden and increasing risk of chronic diseases like CVD.

    “Periodontitis is a local inflammation and a source of low-grade chronic inflammation, which results from haematogenous dissemination of periodontal bacteria or spillover of inflammatory mediators from periodontal tissues to the bloodstream [4, 9], thus contributing to the systemic inflammatory burden, increasing the risk of several chronic diseases like CVD, type II diabetes mellitus (T2DM), renal”

  • Chronic inflammation greatly increases the risk for LOAD.

    “Chronic inflammation has been shown to greatly increase the risk for LOAD (Furman et al., 2019).”

    From Plcg2M28L Interacts With High Fat/High Sugar Diet to Accelerate Alzheimer’s Disease-Relevant Phenotypes in Mice (2022) · cites this paper as Furman et al., 2019

    The section “Systemic chronic inflammation and non-communicable disease risk” lists neurodegenerative diseases among the risks associated with systemic chronic inflammation. It also reports lower Alzheimer’s disease risk among rheumatoid arthritis patients treated with etanercept. Neither passage establishes that chronic inflammation greatly increases the risk of late-onset Alzheimer’s disease (LOAD) specifically; page numbers are not available in our copy. (LLM, conf=0.86)

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-05.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-05.

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.
