Poor oral conditions in older adults are not limited to oral problems, which lead to physical problems. Prior research insufficiently has probed the relationship between oral health and physical function. This study investigated the relationship between oral health status and grip strength in older adults living in the community.
This study used data from the 2014-2018 Korean National Health and Nutrition Survey. Oral health status was assessed by the type of dental prosthesis, the number of teeth. Grip strength was determined as the highest value among the three consecutive measurements of the dominant hand. The covariates included age, income, education, alcohol drinking, smoking, body mass index, sedentary time, comorbidity and number of caries teeth. Multiple logistic regression analysis was performed to examine the association between oral health status and grip strength.
Data on 6,437 older adults (men 2766; women 3671) were analyzed. The mean age was 72.9 ± 0.1 years. In the crude model of logistic regression analysis, both men and women had an association between full denture use and low grip strength compared to high grip strength. After controlling for covariates, the remaining 0-9 teeth was associated with low grip strength compared to high grip strength in men [odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.03-1.88]. The use of full dentures was also associated with low grip strength compared to high grip strength in men (OR = 1.47, 95% CI = 1.09-1.98). No significant associations were found in women.
Low handgrip strength was associated with using full dentures and remaining 0-9 teeth in older men. Low grip strength, one of the key characteristics of sarcopenia and frailty, may serve as an important indicator of poor oral health, especially among men in late life.
老年人的口腔状况不仅限于导致身体问题的口腔问题。先前的研究对口腔健康与身体功能之间的关系研究不足。本研究调查了社区中老年人的口腔健康状况与握力之间的关系。
本研究使用了 2014-2018 年韩国国家健康与营养调查的数据。口腔健康状况通过义齿类型和牙齿数量来评估。握力是通过对惯用手进行三次连续测量得出的最高值来确定的。协变量包括年龄、收入、教育、饮酒、吸烟、体重指数、久坐时间、合并症和龋齿数量。采用多 logistic 回归分析来检验口腔健康状况与握力之间的关联。
对 6437 名老年人（男性 2766 人；女性 3671 人）的数据进行了分析。平均年龄为 72.9±0.1 岁。在逻辑回归分析的粗模型中，与握力高相比，男性和女性使用全口义齿与握力低均存在关联。在控制了协变量后，与握力高相比，男性剩余 0-9 颗牙齿与握力低相关（比值比[OR] = 1.39，95%置信区间[CI] = 1.03-1.88）。使用全口义齿与握力低也与男性握力高相关（OR = 1.47，95% CI = 1.09-1.98）。在女性中未发现显著关联。
握力低与老年男性使用全口义齿和剩余 0-9 颗牙齿有关。握力低是肌肉减少症和虚弱的关键特征之一，可能是口腔健康不良的一个重要指标，尤其是在生命后期的男性中。
