Abstract:

Objective

The purpose of this study was to analyze the association between the Kihon checklist(KCL)score and the risk factors of oral frailty among elderly individuals in Hanzhong community,and to construct a nomogram model to study the accuracy of oral frailty risk assessment for elderly individuals in Hanzhong community.

Methods

A cross-sectional survey was conducted among 385 elderly individuals in three communities of Hanzhong City from May to July 2024,with 179 eligible elderly individuals finally included.The study used convenience sampling and collected data through questionnaires,including general information,KCL scores,and related lifestyle and health status information.Multivariate logistic regression analysis was used to determine the influencing factors of oral frailty,and a nomogram model was constructed based on these factors.The "rms" package in R software was used for model construction and visualization.The performance of the model was evaluated using the receiver operating characteristic(ROC)curve,and the accuracy of the model was verified using a calibration curve.

Results

The study found that age,living alone,nutritional status,and diabetes were independent influencing factors of oral frailty(P<0.05).The constructed nomogram model showed good performance in the ROC curve analysis,with an AUC of 0.757,indicating that the model was useful to assess the risk of oral frailty of the elderly in Hanzhong community.The calibration curve showed that the model's assessment of risk was in good agreement with the actual observed results.

Conclusions

The nomogram model constructed in this study,based on the KCL score,provided an effective tool for assessing the risk of oral frailty among the elderly individuals in Hanzhong community.The model intuitively demonstrated the impact of different factor combinations on the risk of oral frailty among the elderly individuals in Hanzhong community,helping healthcare providers to allocate resources more effectively and intervene on these risk factors.
