This study examined the association between the subjective food intake ability (FIA) using a questionnaire with 30 types of foods and the objective Mixing Ability Index (MAI) using a two-coloured wax cube. A total of 147 subjects (32 males, 115 females, mean age: 54.9 +/- 20.7) were enrolled in this study. The FIA for 30 food types and the key food intake ability (KFIA) for five key food types were obtained using a self-assessed questionnaire to evaluate the subjective chewing ability. The objective chewing ability was evaluated by asking the subjects to chew a wax cube for 10 strokes. The MAI was calculated by image analysis of the chewed wax cube. The Pearson's correlation between the subjective FIA and objective MAI was analysed according to age and number of post-canine teeth lost. The FIA for the 30 foods and five key food types showed a moderate correlation with the MAI (r = 0.51, 0.55, respectively, P < 0.01). The KFIA of the denture wearing group (r = 0.44, P < 0.01) and over 60-year-old group (r = 0.49, P < 0.01) showed a significantly higher correlation with the MAI than the other groups. In conclusion, there was a moderate correlation between the subjective FIA and objective MAI in Korean adults.
本研究使用问卷评估 30 种食物的主观食物摄入能力（FIA），并使用双色蜡块评估客观混合能力指数（MAI），以研究两者之间的相关性。共有 147 名受试者（32 名男性，115 名女性，平均年龄：54.9 +/- 20.7）参与了本研究。通过自我评估问卷获得了 30 种食物的 FIA 和 5 种关键食物的关键食物摄入能力（KFIA），以评估主观咀嚼能力。客观咀嚼能力通过让受试者咀嚼蜡块 10 次来评估。通过对咀嚼后的蜡块进行图像分析来计算 MAI。根据年龄和失牙后犬齿数量，分析了主观 FIA 和客观 MAI 之间的 Pearson 相关性。30 种食物和 5 种关键食物的 FIA 与 MAI 呈中度相关（r = 0.51，0.55，均 P < 0.01）。义齿佩戴组（r = 0.44，P < 0.01）和 60 岁以上组（r = 0.49，P < 0.01）的 KFIA 与 MAI 的相关性明显高于其他组。总之，韩国成年人的主观 FIA 与客观 MAI 呈中度相关。
