Association between visceral adiposity index and cognitive dysfunction in US participants derived from NHANES data: A cross-sectional analysis.

ABSTRACT: This study examines the cross-sectional association between the Visceral Adiposity Index (VAI) and domain-specific cognitive performance in US older adults. We analyzed data from 1323 participants aged ≥ 60 years in the National Health and Nutrition Examination Survey (NHANES) 2011 to 2014. Cognitive function was assessed with CERAD Word‑List Learning (memory/learning), Animal Fluency Test (semantic fluency/executive function), and the Digit Symbol Substitution Test (DSST; processing speed/attention). We fitted a sequence of multiple linear regression models: model 1 (crude), model 2 (adjusted for demographic covariates), model 3 (further adjusted for lifestyle factors), and model 4 (additionally adjusted for clinical comorbidities). Effect estimates are presented as β coefficients with 95
