Relation Between Phase Angle and Tongue Pressure in Older Women
Objectives: The phase angle (PhA) obtained via bioelectrical impedance analysis (BIA) can evaluate skeletal muscle quality and nutritional status. A decrease in the phase angle was reported to be associated with physical activity level; however, the relationship with oral function is unclear. This study aimed to evaluate the relationship between PhA and tongue pressure in older women.
Methods: The study included 16 female outpatients aged ≥65 (78 ± 5) years who visited the Department of Prosthodontics, Tokyo Dental College, Suidobashi Hospital. Body composition data including PhA were measured using BIA (S-10, InBody, Korea); tongue pressure was measured using TPM-01 (JMS, Japan). The participants were divided into low and high PhA (L-PhA and H-PhA, respectively) groups based on PhA value of 4.66, which is the average PhA value of community-dwelling Japanese older women reported by Uemura et al. Tongue pressure was compared between the two groups using the Wilcoxon rank-sum test. The level of significance was set at 0.05. This study was approved by the Ethics Committee of Tokyo Dental College (Approval no. 1069). This work was supported by JSPS KAKENHI Grant Numbers JP21K7073.
Results: The age (mean ± SD) was 79 ± 5 years in the L-PhA group and 77 ± 4 years in the H-PhA group. The PhA (mean ± SD) was 4.3 ± 0.3 in the L-PhA group and 5.0 ± 0.2 in the H-PhA group. The tongue pressure (median) was 31.3 in the L-PhA group and 35.5 in the H-PhA group, showing a significant difference.
Conclusions: The study findings suggest that older women with L-PhA have lower tongue pressure.
