UTILITY OF THE PHASE ANGLE FOR THE DIAGNOSIS OF SARCOPENIA IN GERIATRIC POPULATION

Introduction: Sarcopenia is defined as a decrease in muscle mass and function. In clinical practice there are many difficulties for early identification of sarcopenia, since it depends on the method and cut-off points used to assess each variable. The phase angle (PA) is a bioelectric variable that...

Description
Summary:Introduction: Sarcopenia is defined as a decrease in muscle mass and function. In clinical practice there are many difficulties for early identification of sarcopenia, since it depends on the method and cut-off points used to assess each variable. The phase angle (PA) is a bioelectric variable that reflects the quantity and quality of soft tissues. It reflects the body cell mass and the integrity of cell membranes. Objective: The aim of the study was to evaluate the usefulness of the phase angle as an indicator of sarcopenia in a group of institutionalized elderly people. Methods: Cross-sectional study. 331 subjects institutionalized in centers of Castilla y León and Granada (Spain) (106 men; 225 women) over 65 years old (mean age: 84.5 years) participated in the study. Appendicular skeletal muscle mass (ASMM) and its index (I-MMEA) were estimated using conventional bioimpedance analysis (BIA). Muscle strength was determined through handgrip strength. Sarcopenia was evaluated based on the algorithm of the European Working Group on Sarcopenia in Older People (EWGSOP2). Results were analyzed by Student-t-test, Chisquare test and R2 Pearson. Statistical significance was reached at p
