# An analysis of influencing factors of oral frailty in the elderly in the community

## TL;DR

This study explores factors affecting oral frailty in elderly people in China and identifies key predictors for better community care.

## Contribution

The study identifies specific factors influencing oral frailty in elderly community members and highlights their predictive value.

## Key findings

- Age, gender, education level, and physical frailty are significant factors influencing oral frailty.
- Subjective chewing difficulty and sleep quality show high predictive value for oral frailty.
- Nursing interventions targeting these factors can help reduce oral frailty progression.

## Abstract

This study aimed to investigate the current situation of oral frailty (OF) in the elderly in the community in China and analyse its influencing factors.

Using convenience sampling, 380 elderly people from three communities in our city were selected as participants in the study. The Oral Frailty Index-8, the Frailty Scale, the Oral Health Assessment Tool, the Mini-nutritional Assessment Scale and the Pittsburgh Sleep Quality Index were used to investigate and analyse OF influencing factors.

In this study, the 380 elderly participants were categorized into three groups: frailty, pre-frailty, and non-physical frailty, based on their responses to the questionnaires.The influencing factor analysis showed that age, gender, education level, frailty score, frailty stage, number of dentures, dry mouth, subjective chewing difficulty, oral health score and sleep quality were the influencing factors of OF in the elderly in the community (R2 = 0.712, F = 434.73, P < 0.05). The evaluation of the prediction results showed that the frailty score (area under the curve [AUC]: 0.751, 95% confidence interval [CI]: 0.683–0.862), subjective chewing difficulty (AUC: 0.765, 95% CI: 0.655–0.831) and sleep quality (AUC: 0.736, 95% CI: 0.652–0.781) had a higher predictive value for OF.

The main OF influencing factors in the elderly in the community are age, gender, education level, physical frailty (PF) score, PF stage, number of dentures, dry mouth, subjective chewing difficulties, oral health score and sleep quality. Nursing staff should pay attention to the OF of the elderly in the community and take targeted intervention measures in time to reduce and control OF occurrence and progression.
