다국어 초록 (Multilingual Abstract)

This study aimed to examine differences in sarcopenia related indicators based on age and sex among older adults residing in Bundang-gu. Participants were 36 men and women aged 62 years or older (16 men and 20 women). In accordance with the 2019 AWGS criteria, body composition, SARC-CalF screening tool, handgrip strength, Short Physical Performance Battery (SPPB), Timed Up and Go (TUG) test, International Physical Activity Questionnaire–Korean version (IPAQ-K), health related quality of life (K-SF-36), and subjective socioeconomic status were assessed. Nonparametric statistical methods were applied: sex differences were analyzed using the Mann–Whitney U test with effect sizes (Cohen’s r), and age-related differences were examined using one-way ANOVA and Kruskal–Wallis tests. The significance level was set at α = .05 for all analyses. Results showed no statistically significant differences in sarcopenia indicators across age groups, whereas significant differences were observed between sexes. These findings suggest that Bundang-gu’s high income level, high educational attainment, favorable environmental infrastructure, and overall quality of life may have mitigated age-related health disparities. In contrast, sex differences appear to be influenced by a combination of biological, gender role, and cultural factors. However, due to the small sample size, the findings cannot be readily generalized. Future studies should include larger and more diverse populations across different regions to further validate age and sex specific sarcopenia indicators within varying socioeconomic contexts.
