Health risks are associated with changes in body composition parameters with age. In the present study, body composition parameters (appendicular skeletal muscle mass[ASMM], fat mass [FM], and water content[water])using bioelectrical impedance analysis (BIA)and total skeletal MM (TSMM) measured by 24-h creatinine excretion(Cr)were obtained in 30 male and 38 female healthy subjects. BIA-ASMM in both sexes and Cr-TSMM in females were negatively correlated with aging, and BIA-FM was negatively correlated with BIA-water in both sexes. Of note, Cr-TSMM was a more sensitive marker of MM than BIA-ASMM. Thus, decreases in BIA-ASMM and Cr-TSMM were the most consistent markers of aging and sarcopenia. This study may help promote nursing care for healthy aging.
