The association between oral frailty (OFr) and body action has been investigated, but its association with systemic function remains unclear. Therefore, this cross-sectional study examined the association between OFr with decreased bone mineral density (BMD) and renal function in residents of Shika town, Ishikawa Prefecture, Japan aged ≥40 years. This study included 400 inhabitants. The OFr total score was assessed using three oral domains in the Kihon Checklist (a self-reported comprehensive health checklist), the number of teeth, and brushing frequency per day. Measurements were the estimated glomerular filtration rate (eGFR) and the osteo-sono assessment index (OSI). Using a two-way analysis of covariance ( = 0.002), significantly lower OSI was indicated in the eGFR < 60 and OFr group than in the eGFR of < 60 and non-OFr group after adjusting for age, body mass index, and drinking and smoking status as confounding factors. Multiple logistic regression analysis confirmed this relationship ( = 0.006). Therefore, lower BMD seems to be associated with lower renal function only when accompanied by OFr. Further longitudinal studies are needed to confirm these results.
口腔脆弱（OFr）与身体活动之间的关联已得到研究，但其与全身功能的关联仍不明确。因此，这项横断面研究调查了日本石川县鹿贺町年龄≥40岁居民中OFr与骨密度（BMD）降低及肾功能之间的关联。该研究纳入了400名居民。使用基本检查表（一份自我报告的综合健康检查表）中的三个口腔领域、牙齿数量和每日刷牙频率来评估OFr总分。测量指标为估计肾小球滤过率（eGFR）和骨声评估指数（OSI）。在将年龄、体重指数以及饮酒和吸烟状况作为混杂因素进行校正后，采用双向协方差分析（=0.002）表明，eGFR<60且存在OFr的组中OSI显著低于eGFR<60且不存在OFr的组。多元逻辑回归分析证实了这种关系（=0.006）。因此，似乎只有在伴有OFr时，较低的骨密度才与较低的肾功能相关。需要进一步的纵向研究来证实这些结果。
