Grip strength is a simple indicator of physical strength and is closely associated with systemic health. Conversely, oral health has also been reported to have an important association with systemic health. The present study aimed to assess the effect of oral health status on relative handgrip strength. The data pertaining to 11,337 participants were obtained by means of the seventh Korea National Health and Nutrition Survey (2016 to 2018). Oral health status was evaluated on the basis of the presence of periodontitis and number of remaining teeth (PT, present teeth). Relative handgrip strength was evaluated by means of a digital dynamometer and the value pertaining to the lower 25% of measurements was used as the quartile by gender. The association between oral health status and relative handgrip strength was evaluated by means of multiple regression analysis and multiple logistic regression analysis with covariate correction. Analysis of the crude model revealed a significant association in the group of patients with periodontal disease (odds ratio = 1.69, 95% confidence interval: 1.51-1.89). However, analysis with adjusted covariates revealed that the association was not statistically significant. Moreover, statistical analysis after adjustment for covariates revealed a consistent correlation between PT and relative handgrip strength as categorical and continuous variables. Hence, the present study observed a significant association between oral health status and relative handgrip strength among the Korean adult population.
握力是身体力量的一个简单指标，与全身健康密切相关。相反，据报道口腔健康也与全身健康有着重要关联。本研究旨在评估口腔健康状况对相对握力的影响。通过第七次韩国国家健康与营养调查（2016年至2018年）获取了11337名参与者的数据。根据牙周炎的存在情况和剩余牙齿数量（PT，现存牙齿）评估口腔健康状况。通过数字测力计评估相对握力，并将测量值中处于较低25%的值用作按性别划分的四分位数。通过多因素回归分析和经协变量校正的多因素逻辑回归分析评估口腔健康状况与相对握力之间的关联。粗模型分析显示牙周病患者组存在显著关联（比值比 = 1.69，95%置信区间：1.51 - 1.89）。然而，经协变量调整后的分析显示该关联无统计学意义。此外，协变量调整后的统计分析显示，作为分类变量和连续变量的PT与相对握力之间存在一致的相关性。因此，本研究观察到韩国成年人群中口腔健康状况与相对握力之间存在显著关联。
