Aim: Maximum isometric tongue pressure (MIP) seems to have a diagnostic value for oral phase dysphagia. The present study aimed to examine the association between MIP and frailty, and to assess the screening validity of MIP for physical frailty. Methods: We carried out a cross-sectional study, and enrolled participants aged ≥60 years from Japanese national medical check-ups in 2015 and 2016. The Fried frailty phenotype model was used. We analyzed odds ratios (OR) and 95% confidence intervals (CI) of physical frailty using one standard deviation increments of tongue pressure. Receiver operating characteristic curves were obtained to predict physical frailty using MIP values. Results: Out of 1603 participants, 968 were categorized as non-frail, 605 as pre-frail and 30 as frail. In logistic regression analysis, one standard deviation increment of MIP significantly differentiated frail and pre-frail: the OR for frail with one standard deviation increment in MIP was 0.37 (95% CI 0.26–0.54, P < 0.001), and the OR for pre-frail was 0.63 (95% CI 0.57–0.70, P < 0.001). The area under the receiver operating characteristic curve for predicting frailty with MIP score was as high as 0.776 (95% CI 0.689–0.862). A point of MIP 35 kPa had a sensitivity of 90.0%, specificity of 40.4%, a positive likelihood ratio of 1.5 and a negative likelihood ratio of 0.2 for predicting frailty. Conclusions: MIP performance is independently associated with frailty. MIP also can be used as a simple screening tool for frailty.
