“…Therefore, one can have a high BMI with weak muscle strength due to sarcopenic obesity. Jang[33] reported the prevalence of sarcopenic obesity is 35% in men and 48% in women in elderly Koreans. High prevalence of sarcopenic obesity in women may explain why BMI was not found to be associated with grip strength in women in our study.…”

ObjectivesGrip strength has been used as a measure of function in various health-related conditions. Although grip strength is known to be affected by both physical and psychological factors, few studies have looked at those factors comprehensively in a population-based cohort regarding elderly Koreans. The aim of this study was to evaluate potential factors influencing grip strength in elderly Koreans.MethodsWe evaluated dominant hand grip strengths in 143 men and 123 women older than 65 years who participated in a population-based cohort study, the Korean Longitudinal Study on Health and Aging (KLoSHA). Individuals who had a history of surgery for musculoskeletal disease or trauma in the upper extremity were excluded. Factors assessed for potential association with grip strength were; 1) demographics such as age and gender, 2) body constructs such as height, body mass index (BMI), and bone mineral density (BMD), 3) upper extremity functional status using disabilities of the arm, shoulder and hand (DASH) scores, and 4) mental health status using a depression scale and the short form-36 (SF36) mental health score. Multivariate analyses were performed in order to identify factors independently associated with grip strength.ResultsGrip strengths of dominant hands in elderly Koreans were found to generally decrease with aging, and were significantly different between men and women, as expected. Multivariate analyses indicated that grip strength was independently associated with age, height and BMI in men (R2 = 21.3%), and age and height (R2 = 19.7%) in women. BMD, upper extremity functional status, or mental health status were not found to be associated with grip strength.ConclusionsThis study demonstrates that in elderly Koreans, grip strength is mainly influenced by age and height in both men and women, and additionally by BMI in men. BMD or self-reported physical or mental health status was not found to influence grip strength in elderly Koreans. This information may be helpful in future studies using grip strength as a measure of function in elderly Koreans.

“…Recently, Korea has experienced rapid ageing of population because of decreased birth rate and prolonged average lifespan, and obese population continuously increases because of reduced physical activities resulted from westernized diet and transportation development [1]. According to National Statistical Office, obesity prevalence of adults over 19 in Korea was 30.9% in 2014 and it has been maintained at the level of 31~32% for recent 7 years.…”

“…Decrease in muscle amount reduces basal metabolic rate (BMR), increases body mass, and debases various physical functions [1]. Besides, skeletal muscle is primary tissue responsible for insulin-mediated glucose disposal and it is known that skeletal muscle decrease make influence on insulin resistance separately from obesity [12].…”

“…Additionally, body mass increase triggers insulin resistance by secreting inflammation including cytokine such as interleukin-6 and tumor necrosis factor-alpha, promotes decomposition of myofibrillar protein, reduces protein composition and consequently promotes muscle consumption [13]. As such body mass increase and muscle amount decrease are connected as a vicious circle so it is reported that the presence of both symptoms increases risk of dysfunction and metabolism disorder higher than the presence of either of sarcopenia or obesity [1,7].…”

Purpose: This study was conducted to examine effects of sarcopenic obesity on metabolic syndrome in Korean elders. Methods: This study is based on the analysis of the Korea National Health and Nutrition Examination Survey (KNHANES) with 1,155 subjects (524 men, and 631 women) aged 60 or older, from 2008 to 2011. Sarcopenia was defined as an appendicular skeletal muscle (ASM), divided by weight (%) of <1 SD (standard deviation) below the sex-specific mean for young adults. Obesity was defined as a total body fat percent (men≥25%, women≥35%). Results:The prevalence of SO (sarcopenic obesity) was 13.3% among men and 22.5% among women. Both sexes showed a higher total body fat percent, and the SMI (skeletal muscle index) was the lowest in the SO group. Metabolic syndrome was highly prevalent in the SO group (52.5% men, 60.4% women). The SO group showed a higher risk for metabolic syndrome (odds ratio men 6.57 [95% CI 5.19~7.27], women 3.89 [95% CI 2.41~6.29]) than the obese group (men 3.14 [95% CI 1.76~4.14], women 2.54 [95% CI 1.38~4.65]). Conclusion: SO is a major risk factor for metabolic syndrome in Korean elders. Therefore, a nursing program should be given to the Korean elderly SO group to prevent metabolic syndrome.

“…The following conditions are involved with chronic persistent inflammation related to sarcopenia: degenerative changes in muscles, decreases in anabolic hormone production and increases in resistance, dysfunctional cytokine secretion, nutritional imbalance, and a reduction in physical activity 3) . Sarcopenia reduces normal muscle behavior, and increases the risk of fractures and falls 4) ; furthermore, it is associated with increased mortality and increased hospital admission rates 5,6) .…”

Background: Sarcopenia is a syndrome characterized by the progressive loss of skeletal muscle mass and muscle strength. Although data exist on the prevalence of sarcopenia among the community-dwelling elderly, there is no systematic research on hospitalized elderly patients in Korea, in accordance with the newly developed criteria. Methods: A cross-sectional study was conducted at the Daejin Medical Center, Bundang Jesaeng Hospital, Korea, from May 2013 to March 2015. In this study, we evaluated the levels of hemoglobin, total cholesterol, serum albumin, serum prealbumin, and serum zinc. Handgrip strength was measured with a hand grip dynamometer (FT-7110). Furthermore, the skeletal muscle mass was measured by bioelectrical impedance analysis (BIA). Sarcopenia was defined by skeletal muscle mass as measured with BIA, according to the Asian Working Group for Sarcopenia. Results: Of the hospitalized elderly subjects, 40 (46.5%) had a definite diagnosis of sarcopenia and 46 (53.5%) had no sarcopenia. The prevalence of sarcopenia of the subjects was higher in males than females (males, 46.9% vs. females, 46.3%). The correlation analysis showed that the score of skeletal muscle index (SMI) was negatively correlated with age; whereas, it was positively correlated with the BMI, body weight, and serum prealbumin level. Conclusion: The results of the study showed that sarcopenia was associated with several factors, including age, BMI, serum prealbumin level, among the study subjects. Sarcopenia can be used as a sensitive predictive marker for prognosis of the hospitalized elderly.
