背景在吞咽的口腔准备阶段，舌头负责将食物压在上颚并挤压到咽部。舌压(TP)是舌肌力量的指标，已被观察到随着年龄的增长而下降；最大咬合力(MOF)是咀嚼能力的指标，与TP相关。然而，目前尚无研究探讨TP与MOF的关系。目的探讨健康人群TP与多器官功能衰竭(MOF)的年龄相关性。方法收集785例健康受试者(男305例，女480例)的握力(HGS)、体重指数(BMI)、总蛋白(TP)、多器官功能衰竭(MOF)和牙齿缺失等资料。所有受试者均接受单侧或双侧咬合支持，无论是否存在义齿或天然牙齿。受试者分为两组：成人组(20-50岁，n=497)和老年组(60-80岁，n=288)。进行多元线性回归分析，以确定两组中与TP相关的显著自变量。结果多因素分析显示，TP与年龄(β=-0.153)、体重指数(β=0.205)、血糖(β=0.298)、多动牙功能(β=0.239)显著相关；老年组与年龄(β=-0.266，P=0.001)、体重指数(β=0.160，P=0.005)、多动眼功能障碍(β=0.217，P=0.011)、脱牙(β=0.156，P=0.011)显著相关。结论年龄和多器官功能衰竭分别与老年和成年患者的TP有关，即使在老年开始之前，常规的语言训练也可以预防与年龄相关的TP下降。此外，MOF的恶化可能意味着老年人TP的下降。
Background The tongue is responsible for compressing food against the palate and squeezing it into the pharynx during the oral preparatory phase of swallowing. Tongue pressure (TP), an indicator of tongue muscle strength, has been observed to decline with age; maximum occlusal force (MOF), an indicator of chewing ability, is correlated with TP. However, no study has investigated the relationship between TP and MOF. Objective To investigate the correlation between TP and MOF according to age in healthy individuals. Methods We retrospectively collected handgrip strength (HGS), body mass index (BMI), TP, MOF and tooth loss data for 785 healthy participants (305 men, 480 women). All subjects had either unilateral or bilateral occlusal support, regardless of the presence of dentures or natural teeth. The participants were divided into two groups: an adult (20s-50s, n = 497) group and an elderly (60s-80s, n = 288) group. Multivariate linear regression analysis was performed to determine significant independent variables associated with TP in both groups. Results Multivariate analysis revealed that TP was significantly associated with age (beta = -0.153), BMI (beta = 0.205), HGS (beta = 0.298) and MOF (beta = 0.239) in the adult group (all P < 0.001) and with age (beta = -0.266, P < 0.001), BMI (beta = 0.160, P = 0.005), MOF (beta = 0.217, P = 0.001) and tooth loss (beta = 0.156, P = 0.011) in the elderly group. Conclusions As age and MOF are each associated with TP in both elderly and adult patients, age-related TP decline can be prevented with routine lingual exercises, even before the onset of old age. Additionally, MOF deterioration may indicate a decline in TP for elderly.
