目的：探究营养状况在养老机构老年人口腔衰弱与衰弱间的中介作用。方法：采用横断面设计，纳入南宁市两所养老机构324名老年人。使用口腔衰弱筛查工具(SOFT)、微型营养评估简表(MNA-SF)和临床衰弱量表(CFS)量表分别评估口腔衰弱、营养状况及衰弱，使用层级回归分析及Bootstrap法检验模型。结果：养老机构老年人营养状况得分为10.00 (9.00, 12.00)分、口腔衰弱得分为4.00 (3.00, 5.00)分、临床衰弱得分为5.00 (3.00, 6.00)分。Spearman相关分析口腔衰弱与衰弱呈正相关(r = 0.272, P P P Objective: This paper aims to explore the mediating role of nutritional status in the relationship between oral frailty and clinical frailty among older adults in long-term care facilities. Methods: A cross-sectional study was conducted with 324 older adults from two nursing homes in Nanning. Oral frailty, nutritional status, and frailty were assessed using the Screening for Oral Frailty Tool (SOFT), Mini-Nutritional Assessment short-form (MNA-SF), and the Clinical Frailty Scale (CFS), respectively. A hierarchical regression analysis, combined with bootstrapping, was conducted to test the model. Results: Among the institutionalized older adults, the median (interquartile range) scores were 10.00 (9.00, 12.00) for nutritional status, 4.00 (3.00, 5.00) for oral frailty, and 5.00 (3.00, 6.00) for clinical frailty. Spearman correlation analysis showed a positive correlation between oral frailty and clinical frailty (r = 0.272, P P P < 0.01). Nutritional status played a partial mediating role between oral frailty and clinical frailty, accounting for 30.51% of the total effect. Conclusion: Oral frailty, nutritional risk, and frailty are closely interrelated among older adults in long-term care facilities. I...
