The relationship between oral frailty (OF) and bone mineral density is unclear. This cross-sectional study analyzed the relationship between mineral intake and bone mineral density in middle-aged and older people with pre-oral and OF. The participants, which included 240 people aged 40 years and older, completed the three oral questions on the Kihon Checklist (KCL), which is a self-reported comprehensive health checklist, the brief-type self-administered diet history questionnaire (BDHQ), and the osteo-sono assessment index (OSI). A two-way analysis of covariance on oral function and OSI indicated that the intake of potassium, magnesium, phosphorus, squid/octopus/shrimp/shellfish, carrots/pumpkins, and mushroom was significantly lower in the OF and low-OSI groups than in the non-OF and high-OSI groups. A multiple logistic regression analysis for OF showed that potassium, magnesium, phosphorous and carrots/pumpkins were significantly associated with OF in the low-OSI group but not in the high-OSI group. These results demonstrated that the decrease in mineral intake due to OF was associated with decreased bone mineral density, suggesting that the maintenance of oral function prevents a decrease in bone mineral density.
口腔脆弱与骨密度之间的关系尚不清楚。本横断面研究分析了中年及以上存在口腔前期脆弱和口腔脆弱人群的矿物质摄入量与骨密度之间的关系。参与者包括 240 名年龄在 40 岁及以上的人，他们完成了 Kihon Checklist（KCL）的三个口头问题，这是一个自我报告的综合健康清单，简短的自我管理饮食历史问卷（BDHQ）和骨声评估指数（OSI）。口腔功能和 OSI 的双向方差分析表明，在口腔脆弱和低 OSI 组中，钾、镁、磷、鱿鱼/章鱼/虾/贝类、胡萝卜/南瓜和蘑菇的摄入量明显低于非口腔脆弱和高 OSI 组。口腔脆弱的多因素逻辑回归分析表明，钾、镁、磷和胡萝卜/南瓜在低 OSI 组中与口腔脆弱显著相关，但在高 OSI 组中不相关。这些结果表明，由于口腔脆弱导致的矿物质摄入减少与骨密度降低有关，这表明维持口腔功能可以防止骨密度降低。
