노인의 근감소증과 비만 및 근감소 관련 변인의 관련성 연구

Abstract

In this study, 80 elderly people aged 65 years or older living in Gyeongnam, South Korea were divided into a sarcopenia group (N=37) and a normal group (N=43) using an index determined by dividing the appendicular skeletal muscle mass (ASM), measured using dual-energy X-ray absorptiometry, by the square of height (ASM/Ht2). Obesity-related variables (waist and hip circumferences, body fat ratio, and blood pressure) and muscle reduction-related variables (ASM/Ht2, grip strength, static balance, and 6-minute walking speed) were measured and compared between the two groups. The conclusions are as follows:BR 1. The ASM, waist circumference, hip circumference, left and right grip strengths, and 6-minute walking speed were higher in the normal group than in the sarcopenia group, whereas the body fat ratio was higher in the sarcopenia group (p.05).BR 2. The more obese people showed a smaller ASM, and the people with a larger ASM showed larger waist and hip circumferences and physical (e.g., muscle) strength (p.05).BR 3. We found a difference in the presence or absence of circulatory system diseases according to the presence or absence of sarcopenia(p.05).BR To summarize the results of this study, sarcopenia in the elderly is highly correlated with body fat and muscle reduction-related variables. Among the muscle reduction-related variables, grip strength, which corresponds to muscle strength, and 6-minute walking distance, which corresponds to endurance, were found to be highly correlated with sarcopenia. This highlights the importance of obesity and fitness management in sarcopenia.
