Undernutrition is associated with frailty, one of the common reasons for seeking long-term care. In older adults, nutritional status is known to be associated with oral function; however, it is not yet known if there is a similar association in middle-aged adults. The present study determined the association between nutritional status and oral function in middle-aged adults.
This cross-sectional study was conducted in 117 outpatients aged 40-64 years who underwent dental check-up at a private dental clinic. Factors associated with oral function, including oral moisture, number of teeth present, oral diadochokinesis, tongue pressure, lip-seal strength, and masticatory performance, were evaluated. Body mass index (BMI), fat-free mass index (FFMI), and skeletal muscle mass index (SMI) were analyzed as nutritional statuses. Pearson's correlation analysis was conducted to determine the correlation between nutritional statuses and other variables. Multiple linear regression analysis was performed, with adjustment for age and sex, using BMI, FFMI, or SMI as response variables and oral moisture, maximum tongue pressure, lip-seal strength, oral diadochokinetic rate, and masticatory performance as explanatory variables.
All nutritional statuses showed significant correlation with maximum tongue pressure and lip-seal strength. Multiple linear regression analysis revealed that BMI was associated with maximum tongue pressure and lip-seal strength, whereas FFMI and SMI showed significant association with sex, maximum tongue pressure, and lip-seal strength.
In middle-aged outpatients at a regional dental clinic, lip-seal strength and tongue pressure were positively associated with BMI, FFMI, and SMI.
营养不良与衰弱有关,衰弱是寻求长期护理的常见原因之一。在老年人中,营养状况与口腔功能有关;然而,中年人是否存在类似的关联尚不清楚。本研究旨在确定中年人营养状况与口腔功能之间的关系。
这是一项横断面研究,共纳入了 117 名 40-64 岁在私人牙科诊所接受牙科检查的门诊患者。评估了与口腔功能相关的因素,包括口腔湿润度、现存牙齿数、口腔交替运动速度、舌压、唇封强度和咀嚼性能。身体质量指数(BMI)、去脂体重指数(FFMI)和骨骼肌质量指数(SMI)作为营养状况进行分析。采用 Pearson 相关分析来确定营养状况与其他变量之间的相关性。采用多元线性回归分析,以 BMI、FFMI 或 SMI 作为反应变量,以口腔湿润度、最大舌压、唇封强度、口腔交替运动速度和咀嚼性能作为解释变量,调整年龄和性别后进行分析。
所有营养状况均与最大舌压和唇封强度呈显著相关。多元线性回归分析显示,BMI 与最大舌压和唇封强度相关,而 FFMI 和 SMI 与性别、最大舌压和唇封强度显著相关。
在区域性牙科诊所的中年门诊患者中,唇封强度和舌压与 BMI、FFMI 和 SMI 呈正相关。
