Overview

•We examined the relationship between oral frailty and sarcopenia in older outpatients.•Approximately 40% of patients met the criteria for oral frailty.•Oral frailty and sarcopenia were not significantly related.•An association was observed between tongue function and sarcopenia. In this study, we aimed to investigate the prevalence of oral frailty and explore its relationship with oral function and sarcopenia among older outpatients. In this cross-sectional study, we retrospectively included older patients who visited a frailty outpatient clinic. We assessed total oral frailty employing, among other measures, oral diadochokinesis (/ta/ sound) for tongue–lip movement and tongue pressure. Patients who did not meet the cut-off values for three or more of these were classified as having oral frailty. Sarcopenia was assessed according to Asian Working Group for Sarcopenia 2019 criteria and analyzed for the relationship with oral function. The mean ± standard deviation age of the 111 patients was 77.2 ± 5.7 y; 63 were women (57%). Fifteen patients (14%) had either sarcopenia or dynapenia. The overall prevalence of oral frailty was 38%, with no significant difference in its prevalence between the sarcopenia/dynapenia group (44%) and the robust (no sarcopenia/dynapenia) group (35%). The following oral function assessments significantly differed between the sarcopenia/dynapenia group and the robust group: median (interquartile range) total oral frailty score, 2 (2–4) and 2 (1–3) (P = 0.019); tongue–lip motor function, 5.4 ± 1.2 and 5.9 ± 1.2 times/s (P = 0.049); and tongue pressure, 27.3 ± 8.5 kPa and 31.7 ± 8.0 kPa (P = 0.009). Approximately 40% of patients exhibited a decline in oral function regardless of the presence of sarcopenia. Sarcopenia and dynapenia may particularly affect tongue function. Although assessing patients for sarcopenia is crucial, separate evaluations of oral function should also be considered.
