Outline of Final Research Achievements

The purpose of this study is to contribute to the problem solving of eating behaviors of extremely low birth weight(ELBW) infants by clarifying the relationship between eating swallowing function and skeletal muscle mass. We investigated healthy and low birth weight(LBL) infants. Survey items were sex, age, height, weight, occlusal force(OF), tongue pressure(TP), mouth rinsing function test(MRFT), grip force(GF), calf circumference, body composition. Regardless of birth weight, TP, OF, MRFT score correlated with age and skeletal muscle mass. In LBL infants, even if age factor was excluded, TP and GF correlated, and the strength of correlation was stronger than that of normal birth weight infants. Therefore, the eating swallowing function was shown to be easily affected by the GF, which is an indicator of the muscular force of the whole body. Even in ELBW infants, the importance of considering systemic development was suggested to solve the problem of eating behaviors.
