Association between composite dietary antioxidant index and increased urinary albumin excretion: a population-based study.

ABSTRACT:

Introduction

The Albumin-Creatinine Ratio (ACR) is a key biomarker for early kidney disease detection and is predictive of chronic kidney disease (CKD) progression and associated cardiovascular risks. Antioxidant diets, indicated by the Composite Dietary Antioxidant Index (CDAI), may reduce oxidative stress and alter albumin urinary excretion rates. This study explores the relationship between CDAI and albuminuria.

Materials and methods

Data on intake of vitamins A, C, E, zinc, selenium, and beta-carotene from the NHANES database (2007-2018) were used to compute CDAI scores. To measure urinary albumin, the ACR levels were assessed. The association between CDAI and ACR was analyzed through multivariate logistic regression, subgroup analysis, and interaction tests, incorporati
