Association between the composite dietary antioxidant index and sarcopenia risk in American adults: a cross-sectional NHANES study.

ABSTRACT:

Background

Given the absence of specific pharmacological treatments for sarcopenia, identifying effective lifestyle and dietary interventions is imperative. This study aims to explore the association between the composite dietary antioxidant index (CDAI) and sarcopenia, offering new insights into nutritional strategies for sarcopenia-prone populations.

Methods

This cross-sectional study analysed secondary data from the National Health and Nutrition Examination Survey cycles spanning 2001-2006 and 2011-2018. Weighted multivariate logistic regression and restricted cubic spline (RCS) analyses were employed to evaluate the non-linear association between CDAI and sarcopenia and to perform stratified analyses.

Results

In this study, encompassing 19 683 American adults, rep
