노인여성에서 신체구성과 혈류동태 지표들의 관련성 및 공통성

Abstract

The main purpose of this study is to find the relations and common factors regarding the body composition and hemodynamic variables. The subjects were 257 elderly Korean women (mean age 69.32 years). Body composition measurement items were minerals, muscle mass(MM), fat mass(FM), body fat percentage(BFP), waist-hip ratio(WHR) and body mass index(BMI). Hemodynamic factors were systolic blood pressure(SBP), diastolic blood pressure(DBP), resting heart rate(HR), pulse wave korotkoff sound systolic time(TP-KS), pressure rate product(PRP), stroke volume(SV), cardiac output(CO), cardiac index(CI) and total peripheral resistance(TPR). Data assessment for Pearson`s correlations and common factors was analyzed using SPSS (ver. 19.0). The results are as follows. First, there was no significant correlations between body compositions and hemodynamic variables in elderly Korean women. Second, MM and WHR were significantly related to all of body compositions. There were statistically significant positive relationships between MM and obesity. Third, hemodynamic variables such as SBP, HR, PRP, CO were TPR modulators which affect blood circulations throughout whole-body. Fourth, arteriosclerosis index(TP-KS) displayed a negative relationship with HR, however there were no any significant correlations between TP-KS, body compositions and hemodynamic variables. Fifth, measuring body compositions and hemodynamic items such as FM, minerals, CO, DBP, HR can be used to help figure out most of the body composition and hemodynamic conditions in elderly Korean women. In summary, the relationships between body compositions and hemodynamic variables were no significance, which suggests that the body compositions and hemodynamic elements in elderly Korean women should be interpreted and took care of as a independent factor for elderly health management. Controling muscle mass and abdominal obesity would be helpful for managing all of body composition and elderly health. Mild obesity in elderly Korean women may have positive effects on keeping muscle mass and expanding lifespan. Senile arteriosclerosis may be more affected by other components than body compositions and hemodynamic variables.
