Factors Affecting the Quality of Life in Low-Income Older Adults with Sarcopenia: A Cross-Sectional Study

Purpose: This study aimed to identify the factors influencing quality of life (QoL) of low-income older adults (LOAs) with sarcopenia. Methods: A convenience sample of 125 older adults was recruited from Jeonbuk Province, South Korea. Data were collected using a self-report questionnaire that included nutritional status, the Depression Anxiety Stress Scale-21, and the World Health Organization Quality of Life Instrument-Older Adults Module. Additionally, grip strength and appendicular skeletal muscle mass, were evaluated, along with the short physical performance battery. Results: Sarcopenia and severe sarcopenia were observed in 43.2% and 56.8% of participants, re-spectively. Using multiple regression analysis, depression (β =-.40, p < .001), nutritional status (β = .24, p = .003), and anxiety (β =-.15, p = .042) were identified as factors affecting the QoL of the older adults in low-income groups with sarcopenia, the explanatory power of these variables was 44%. Conclusion: The results of this study can be used to develop a nursing intervention program and establish poli-cies to improve depression, anxiety, and nutritional status to enhance QoL of LOAs with sarcopenia.
