A systematic review assessing the association of deteriorating oral function with nutrient intake in older adults. Methods Comprehensive evidence gathering from CBMdisc, CNKI, Wanfang Database, PubMed, Embase, Web of Science, and Cochrane Library, to examine how oral frailty relates to dietary inadequacy among seniors. Retrieval period from June 30, 2014 to June 30, 2024.Two researchers independently screened the literature, extracted data, and assessed the quality of the included studies, using Revman 5.4 and Stata 16.0 for the systematic review. Results With an aggregate sample of 7,234 subjects across eight selected studies, the analysis contained seven cross-sectional designs and a single prospective cohort. Meta-analysis results demonstrate that malnutrition susceptibility rises markedly in the elderly with compromised masticatory capacity. (OR=1.93,95% CI:1.62-2.30), with a statistically significant difference (Z=7.27, P 0.05); The study area for the Japanese subgroup showed statistical significance OR=1.43, 95% CI:1.08-1.89, P=0.01.Conclusions Although nutritional status correlates with oral frailty in the elderly population, equivocal evidence persists regarding how tooth retention and oromotor skill deterioration impact nutritional outcomes. This necessitates greater attention to the collaborative management of oral health and nutritional status, which in turn can provide clinical decision-making and intervention strategies for preventing and controlling oral frailty in the elderly.
