| Outline of Final Research Achievements |
Focusing on the tongue and mass muscle of the child, a questionnaire was sent to the parents of 209 infants who attend the nursery school, and the infant measured the grip strength, body composition, bite force, tongue pressure and tongue thickness. The
The tongue pressure (kPa) was 3 years old: 11.8 ± 7.7, 4 years old: 16.7 ± 7.5, 5 years old: 22.1 ± 9.5, 6 years old: 25.4 ± 8.2, and significantly correlated with age. In addition, tongue pressure showed significant correlation with height, weight, grip strength and skeletal muscle mass. There was no significant correlation with occlusal force and tongue thickness. It was suggested that children with problems with oral function may have low tongue pressure. In addition, tongue pressure was associated with grip strength, suggesting an association with physical function and general muscle strength.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、幼児期に比較的多い食の問題について、解決策の一つとなるような指標づくりをt業音波エコー装置を用いる事によって行った。食の問題点は歯列の完成や口腔機能と密接に関係しているが、今回の結果から特に舌の圧力が有意に相関を得た。全身筋力、特に握力と舌圧との相関は高い結果となったため、今後、食に問題行動を生じる幼児に対しては、専門家の行う舌圧測定のみならず握力測定が全身の筋肉の習熟度の判定に用いることが出来ることが示唆された。
