背景：身体功能的恶化使老年人容易跌倒，因此众所周知，这促使老年人需要长期护理。在这方面，口腔功能可能与运动功能的丧失有关。这项横断面研究评估了增加老年人跌倒风险的口腔因素。方法：我们调查了672名年龄≥ 65岁的农村自立老人。我们评估了每个受试者跌倒的风险和任何相关的焦虑。还评估了口腔相关状况（牙齿数量、咬合支持、咀嚼性能、咬合力和舌压）和身体运动功能（步态速度、膝关节伸展力和单腿站立）。使用Mann-Whitney U检验、卡方检验和逻辑回归模型进行统计分析。结果：在所有受试者中，23%的人有跌倒史，40%的人对跌倒感到焦虑。这两个因素在女性受试者中显著更高，她们也有较慢的步态速度和更大的咬合横向差异。有跌倒史的受试者年龄较大，身体运动功能受损，咬合力下降，左/右咬合不平衡。我们发现，对于摔倒的焦虑也有类似的趋势。结论：这些结果显示，保持健康的牙齿咬合和促进健康的口腔功能，可能会减少跌倒的风险。
Background: Deteriorated physical function makes older adults prone to fall, and it is therefore known to prompt elders to require long-term care. In this regard, oral function can be related to the loss of motor function. This cross-sectional study assessed the oral factors that increase the risk of falling among older adults. Methods: We surveyed 672 self-reliant elderly individuals aged >= 65years who were dwelling in a rural area. We assessed each subject's risk of falling and any related anxiety. Oral-related conditions (number of teeth, occlusal support, masticatory performance, occlusal force, and tongue pressure) and physical motor functions (gait speed, knee extension force, and one-legged standing) were also assessed. Statistical analyses were performed using Mann-Whitney's U-test, the chi(2) test, and a logistic regression model. Results: In all subjects, 23% had a history of falling, while 40% had anxiety over falling. Both factors were significantly higher among female subjects, who also had slower gait speeds, and greater lateral differences in occlusion. The subjects with histories of falling were older, had impaired physical motor function, and exhibited a decrease in occlusal force and left/right occlusal imbalances. We recognized similar trends for anxiety about falling. Conclusions: These results revealed that the risk of falling might be lessened by maintaining healthy teeth occlusion and promoting healthy oral function.
