Objective:To investigate the correlation between age and tongue pressure in healthy individuals using a newly-developed tongue pressure measuring device.Methods:A total of 154 healthy volunteers aged 20 to 97 years, without noticeable swallowing difficulties, were selected and divided into seven age groups: 20-29 years ( n=24), 30-39 years ( n=22), 40-49 years ( n=20), 50-59 years ( n=24), 60-69 years ( n=22), 70-79 years ( n=22), and 80 years or more ( n=20). Their maximum, minimum, average and initial pressures, work done, and coefficients of variation were measured using the newly designed tongue pressure measuring device in its intermittent and continuous measurement modes. The tongue pressures were correlated with age and gender. Results:The pressure data obtained using the new device were completely consistent with those from a manometer ( R=1). In the intermittent measurement mode, the readings showed that the maximum, minimum and average tongue pressures decreased significantly with age. In the continuous measurement mode, the initial tongue pressure, average pressure and work done also decreased significantly with age, while the coefficient of variation generally increased with age. There was a negative correlation between age and average tongue pressure ( R2=0.4). The relationship could be expressed as y=-0.8595x+ 103.3 (where x is age, and y is tongue pressure). However, no significant correlation was found between gender and tongue pressure. Conclusions:Tongue pressure and its stability are negatively correlated with age in healthy individuals without swallowing dysfunction, showing no significant correlation with gender.
