Fine and Gray\u2019s competing risk model, multivariable linear regression, and Cox proportional hazards models were employed.

Five inflammation biomarkers (NLR, PLR, SII, SIRI, and IBI) were positively associated with both MetS and CRC risk.

Systemic low-grade inflammation has been proposed as a mediator, yet composite inflammation indices are underexplored. What this study adds: In 335\u2009544 UK Biobank participants, MetS was associated with a higher risk of CRC (HR\u2009=\u20091.11, 95% CI 1.03\u20131.20). Five systemic inflammation biomarkers (NLR, PLR, SII, SIRI, and IBI) were associated with both MetS and CRC. Mediation analysis indicated partial mediation, with IBI contributing the largest proportion (16.6%). How this study might affect research, practice, or policy: Incorporating systemic inflammation indices, particularly IBI, may improve early risk stratification for CRC among individuals with MetS. These findings support the development of prevention strategies targeting low-grade inflammation, while guiding future mechanistic and translational research.<\/jats:p>\n
