This Frontiers in Nutrition study (N=311; Northern Sichuan, China) applied TPB-aligned measures (nutrition attitude, perceived social support, IADL, self-efficacy) to model nutritional literacy in adults ≥60 years from three villages. Hierarchical regression showed education positively predicted nutritional literacy (β=0.126), denture use due to tooth damage negatively predicted it (β=−0.077), and both nutrition attitude (β=0.312) and perceived social support (β=0.243) were positive predictors, whereas daily living ability exhibited a negative coefficient (β=−0.251)—consistent with higher IADL scores reflecting worse function. SEM indicated nutrition attitude had direct (0.333) and indirect (0.050) effects on nutritional literacy; daily living ability showed direct (−0.481) and indirect (−0.101) effects, with self-efficacy partially mediating both pathways. Implication: strengthening attitudes, social support, and self-efficacy while addressing oral health and functional limitations may raise nutritional literacy in rural aging populations.
