本研究的目的是阐明咀嚼能力的自我评估是否（咀嚼能力）与身体的肌肉力量显著相关，所述肌肉力量被评估为在调整混杂变量（包括年龄、性别、身高、体重、就业状况、家庭类型、教育背景、社会交往、慢性医学状况、吸烟习惯、饮酒习惯和牙列状况。共有381名年龄在67-74岁之间的人入组。咀嚼能力分为三类：咀嚼各种食物的能力，仅咀嚼稍微硬的食物的能力，或仅咀嚼软的或泥状食物的能力。测量握力，并使用生物阻抗分析来估计SMM。采用单因素方差分析和Bonferroni方法分析三组咀嚼能力之间的握力和SMM差异。以咀嚼能力为因变量，握力为主要自变量，建立有序回归模型。那些只能咀嚼软的或泥状食物的人的握力明显低于那些能咀嚼各种食物的人。咀嚼能力三组间的SMM无显著性差异。在调整SMM、牙列状态和背景因素后，咀嚼能力与握力显著相关。咀嚼能力可能与评价为握力的身体肌肉力量有关，但与评价为SMM无关。
The aim of the present study was to elucidate whether self-assessed masticatory ability (masticatory ability) is significantly related to muscle strength of the body evaluated as handgrip strength and skeletal muscle mass of the whole body (kg) (SMM) after adjusting for confounding variables, including, age, gender, height, weight, employment status, type of household, educational background, social interaction, chronic medical conditions, smoking habit, drinking habits and dentition status among the elderly. A total of 381 persons aged 67-74 years were enrolled. Masticatory ability was classified into one of three categories: ability to chew all kinds of food, ability to chew only slightly hard food or ability to chew only soft or pureed food. Handgrip strength was measured, and bioimpedance analysis was used to estimate SMM. One-way analysis of variance and Bonferroni methods were used to examine differences in handgrip strength and SMM among the three groups of masticatory ability. An ordinal regression model was conducted with masticatory ability as the dependent variable and handgrip strength as the principal independent variable. Handgrip strength was significantly lower in those individuals who could chew only soft or pureed food than in those individuals who could chew all kinds of food. No significant difference in SMM was found among the three groups of masticatory ability. Masticatory ability was significantly related to handgrip strength after adjusting for SMM, dentition status and background factors. Chewing ability may be related to muscle strength of the body evaluated as handgrip strength, but not evaluated as SMM.
