Data were obtained from 21\u00a0476 participants in the Fuqing Cohort Study who completed a FFQ. Dietary quality was assessed using the Healthy Eating Index (HEI), Diet Quality Index (DQI) and Diet Balance Index (DBI). Logistic regression models were used to examine associations among dietary quality, inflammatory markers and glycemic status. Mediation models were employed to evaluate potential mediating effects of eleven systemic inflammatory markers. All three dietary indices were inversely associated with diabetes risk. Compared with participants in the lowest dietary quality category, the adjusted OR (95 % CI) of the highest dietary quality category were 0\u00b7863 (0\u00b7768, 0\u00b7970) for HEI, 0\u00b7719 (0\u00b7640, 0\u00b7807) for DQI and 0\u00b7852 (0\u00b7754, 0\u00b7961) for DBI. Single-mediator analyses showed potential indirect effects of the HEI on diabetes risk via total white blood cell count, neutrophil, monocyte counts, neutrophil-to-lymphocyte ratio and systemic immune-inflammation index, with mediated proportions of 10\u00b767 %, 11\u00b732 %, 4\u00b705 %, 3\u00b722 % and 3\u00b726 %, respectively. In the parallel multiple mediation model including all mediators, a potential indirect effect (OR = 0\u00b7980; 95 % CI: 0\u00b7759, 0\u00b7963) was observed, with a mediated proportion of 8\u00b783 %. Higher dietary quality, as assessed by the HEI, DQI and DBI, is inversely associated with hyperglycaemia risk and linked to lower levels of systemic inflammatory markers. The adverse association of poor dietary quality with diabetes risk may be partially mediated by systemic inflammatory factors.<\/jats:p>","DOI":"10.1017\/s0007114526108605","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T09:35:13Z","timestamp":1792056913000},"page":"1-11","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Effects
