Background: The cut-off value of tongue pressure on the ability to perform activities of daily living could be a
useful indicator for preventing deterioration of the ability to perform activities of daily living. This study aimed to
investigate the relationships among swallowing function, including tongue pressure, nutrition status, and physical
function and ability to perform activities of daily living and establish a cut-off value in hospitalized old-old and very
old patients.
Methods: A total of 98 hospitalized patients aged ≥ 75 years were recruited in this cross-sectional study. Swallowing
function (tongue pressure and Dysphagia Risk Assessment for the Community-dwelling Elderly), nutrition status
(body mass index, albumin, and Mini Nutritional Assessment Short Form version), physical function (timed up and
go test), and ability to perform activities of daily living (Barthel index) were measured. Patients were divided into
two groups based on the ability to perform activities of daily using Barthel index (Group 1, high ability, and Group
2, low ability).
Results: Group 2 had lower swallowing function, nutrition status, and physical function compared with Group 1
(p<0.05). In the multiple logistic regression analysis, tongue pressure was an independent explain at or for Barthel
index (p<0.05), and the cut-off value of tongue pressure for the ability to perform activities of daily living could be
set using receiver operating characteristic curves.
Conclusion: The cut-off value of tongue pressure could be a useful indicator for maintaining or improving the
ability to perform activities of daily living in hospitalized old-old and very old patients.
