ABSTRACT
BACKGROUND:
We evaluated the prevalence of sarcopenia, presarcopenia, and severe sarcopenia in healthy Korean elderly women.METHODS:
We measured the muscle mass and muscle function of 196 ambulatory women over the age of 65 years who visited the University Hospital Menopause Clinic. Appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry to measure skeletal muscle mass index (SMI). Assessment of hand grip strength (HGS) of the dominant hand was performed to measure the muscle strength, and 4-m straight on-way path was used to measure gait speed for physical performance. The values used to define the presarcopenia, sarcopenia, and severe sarcopenia were based on the cutoff values proposed by the Asian Working Group for Sarcopenia (AWGS).RESULTS:
The mean age of women was 71.2 years, and the mean SMI in 196 women was 5.94 kg/m2. The average HGS was 20.3 kg, and the mean gait speed was 1.08 m/sec. In 41 out of the 196 women (20.9%), the SMI was reduced to less than 5.4 kg/m2. Fifty-nine women (30.1%) had HGS of less than 18 kg, and gait speed was less than 0.8 m/sec in 12 women (6.1%). Twenty-six women (13.3%) were classified into the presarcopenia stage, and 15 women (7.6%) were classified into the sarcopenia stage. There was no case of severe sarcopenia.CONCLUSIONS:
One out of five relatively healthy women aged more than 65 years showed a decrease in muscle mass, and 7.6% of women showed a decrease in muscle mass and strength. The sarcopenia stage was also intensified with aging.
