Association between composite dietary antioxidant index and hyperlipidemia in adults based on the NHANES.

ABSTRACT: Hyperlipidemia, a major risk factor for cardiovascular diseases, can potentially be alleviated by dietary antioxidants. This study explored the relationship between hyperlipidemia and the Composite Dietary Antioxidant Index (CDAI), which measures antioxidant intake from carotenoids, selenium, zinc, and vitamins A, C, and E. Analyzing data from 27,493 participants aged 20 and older from the National Health and Nutrition Examination Survey (NHANES) conducted between 2001 and 2018, we used weighted regression models to assess this association while adjusting for multiple covariates. Restricted cubic splines were also applied to check for any non-linear relationships. Findings revealed that higher CDAI scores significantly correlated with lower hyperlipidemia prevalence. Specifically, each uni
