Composite dietary antioxidant index of antioxidant vitamins and sarcopenia risk: insights from the UK biobank and NHANES cohorts.

ABSTRACT:

Background

The composite dietary antioxidant index (CDAI), reflecting total dietary intake of antioxidant vitamins, may indicate overall antioxidant capacity. This study examined its association with the risk of probable sarcopenia, defined by handgrip strength, in older adults.

Methods

Participants aged over 60 from the UK Biobank (N = 22,921) and National Health and Nutrition Evaluation Surveys (NHANES) 2011-2014 (N = 2,641) cohorts were categorized into probable sarcopenia and non-probable sarcopenia groups. Multivariable logistic regression models assessed the associations between CDAI (both continuous and quartile) and its components (vitamin A, vitamin C, vitamin E, and carotene) with probable sarcopenia risk in cohorts, with sex subgroup and sensitivity analyses to va
