Chinese Dietary Indices and Glioma: New Insights of a Case–Control Study in the Chinese Population

Identifying modifiable factors in primary prevention strategies is a typical goal of glioma epidemiology. Among many risk factors, diet was always considered as one. Most the relevant studies thus far were concentrated on West. It crucial to investigate connection between Chinese and gliomas given stark variations western eastern diets. A food frequency questionnaire including 114 items used intake study subjects. The Dietary Quality Index (CDQI), Balance (CDBI), Antioxidant (DAI), Inflammation (DII), Healthy Eating (CHEI) calculated based data provided by evaluate dietary quality, balance, antioxidants, inflammation adherence guidelines 506 patients controls, respectively. After adjusting covariates, CHEI (OR = 0.90, 95% CI: 0.88–0.93) DAI 0.61, 0.54–0.70) correlated reduced risk, CDBI-based undernutrition 1.08, 1.06–1.12) overnutrition 1.14, 1.09–1.20) DII 2.20, 1.81–2.68) an elevated risk. Moreover, restrictive cubic spline analysis showed that there significant nonlinear dose–response relationships CHEI, CDBI, DAI, DII, glioma. Therefore, adhering connected with lower associated increased
