Popis: Abstract Antioxidant-rich diets serve as protective factors in preventing obesity. The composite dietary antioxidant index (CDAI) represents a novel, comprehensive metric for assessing the antioxidant capacity of diets. Our objective is to investigate the relationship between the CDAI and obesity prevalence among adults in the United States. Dietary and anthropometric information about adults aged 20 years and older were obtained from the National Health and Nutrition Examination Survey (NHANES) 2007–2018. The CDAI was derived from six dietary antioxidants. Obesity is defined as a body mass index (BMI, kg/m2) ≥ 30 kg/m2, and abdominal obesity as a waist circumference (WC, cm) ≥ 102 cm for men and ≥ 88 cm for women. The relationship between CDAI and obesity, including abdominal obesity, was analyzed using logistic regression and subgroup analyses. A total of 25,553 participants were analyzed. With higher tertiles of the CDAI, both obesity (41.28% vs. 38.62 vs. 35.09%, P
