Association between the composite dietary antioxidant index and chronic kidney disease: evidence from NHANES 2011–2018

Abstract

There is growing evidence that antioxidant-rich diets protect against chronic kidney disease (CKD).

Interactive association of the dietary oxidative balance score and cardiovascular disease with mortality in older adults: evidence from NHANES

“…For example, the Composite Dietary Antioxidant Index (CDAI) as an individual's comprehensive measure of antioxidant capacity has been linked to reduced risks of diabetes, CVD, chronic kidney disease, cancer and mortality. 18,37–40 The CDAI score is derived from a limited set of six dietary nutrients, specifically vitamins A, C, and E, along with manganese, selenium, and zinc, all of which possess antioxidant properties. 41 However, it should be noted that our diet not only provides us with antioxidant nutrients but also pro-oxidant ones.…”

Association between composite dietary antioxidant index and kidney stone prevalence in adults: data from National Health and Nutrition Examination Survey (NHANES, 2007–2018)

“…To mitigate potential confounding bias in our analyses, we selected covariates based on clinical expertise and previous research ( 27 ). The NHANES datasets provided information, including age (years), sex (male or female), race/ethnicity (Mexican American, other Hispanic, non-Hispanic White, non-Hispanic Black, or other), education level (below high school, high school, or above high school), total energy intake (kcal/day), serum calcium (mmol/L), estimated glomerular filtration rate (eGFR; ml/min/1.73 m2), and supplement use (%).…”

Association between the Composite Dietary Antioxidant Index and Nonalcoholic Fatty Liver Disease: Evidence from National Health and Nutrition Examination Survey 2005-2016

“…The nutritional estimates did not include any nutrients obtained from dietary supplements or medications. The average of the two 24-hour intakes was taken as the daily dietary intake for the present study 22 .…”

“…In this formula, represents the individual daily intake of antioxidant components; represents the mean of ; represents the standard deviation for [22][23][24] De nition of Outcome NAFLD was de ned according to the USFLI which was developed using the NHANES database, which was moderately improved accuracy compared to the Fatty Liver Index (FLI) in the multiethnic US population 12 . And it has been validated and used in several previous studies [25][26][27] .…”
