| Research Abstract |
For the purpose of extracting potential risk factors for aspiration and suffocation in the elderly, a survey on swallowing functions was conducted among the elderly who sustained themselves in daily life. For evaluation of oral functions, measurement of tongue pressure was also conducted. A potential decline in swallowing functions was observed in about 12% of this object. Such a trend was stronger in those aged 75 and over, who showed "prolonged eating time" and "a propensity for soft diet" among the oral stage items significantly more frequently than those aged 65 to 74.
The results demonstrated that in the elderly aged 75 and over, decreased chewing functions, which are essential in the formation of a bolus, was important as a potential risk factor for aspiration and suffocation. Additionally, tongue pressure was found to significantly correlate with tongue muscle strength, indicating that tongue pressure measurement was useful in evaluating tongue functions.
