Hypothesis-generating cross-sectional data on metabolic indices and circadian syndrome

Associations between multiple metabolic indices and circadian syndrome: a cross-sectional study with mediation analysis of the C-reactive protein triglyceride glucose index.

Inflammatory markers and metabolic measures interact to influence circadian rhythm disruption, suggesting new targets for prevention research.

This large cross-sectional study (n=6507) identifies significant non-linear associations between multiple metabolic indices and circadian syndrome, with the CRP-triglyceride glucose index (CTI) showing patterns consistent with mediation (20.8-86.5% of total effect). The findings support a 'metabolic-inflammatory axis' contributing to circadian syndrome but require prospective confirmation.

Why it surfaced

Large Chinese cohort study (n=6507) on circadian syndrome and multiple metabolic markers. Hypothesis-generating cross-sectional design limits clinical applicability; mediation analysis provides mechanistic clues. Score limited by cross-sectional design and Chinese-specific population (CHARLS).
