The Association between Sarcopenia with Body Fat Composition and Basal Metabolic Rate in Community-Dwelling Elderly in Bali
Background: Age-related changes in body composition follow advancing age. Changes will also occur in the basal metabolic rate (BMR) and fat composition. Sarcopenia, which is closely related with changes in body fat composition, can also affect elderly people. The purpose of this study is to investigate the association between sarcopenia, body fat composition and BMR in community-dwelling elderly in bali. Materials and Methods: This study uses analytic cross-sectional study design. Sarcopenia data was collected using SARC-F, body fat composition, BMR and BMR/BSA. Bioimpedance Analysis (BIA) was used to determine the makeup of body fat. The Spearman correlation test and multivariate analysis were used to analyze the data. Result: This research had 108 individuals in total. The mean age is 67.56±5.69 years. A total of 49 subjects (45.4%) were male and 59 subjects (54.6%) were female. Correlation test obtained a positive correlation between sarcopenia (SARC-F) with fat% (r = 0.16, p = 0.01) and subcutaneous arm fat (r = 0.148, p = 0.02). While BMR and BMR/BSA have a negative correlation with sarcopenia (SARC-F). After multivariate analysis, it was found that BMR had a negative correlation with sarcopenia (SARC-F) (r = -0.217, p = 0.025). Conclusion: Compared to elderly people who do not have sarcopenia, sarcopenic elderly exhibit alterations in body fat composition and BMR. As determined by the SARC-F, BMR and body fat composition are also linked to sarcopenia.
