Abstract PDF: 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, respectively. 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 policies to improve depression, anxiety, and nutritional status to enhance QoL of LOAs with sarcopenia.

Development and Effects of Combined Exercise Program for Older Adults with Sarcopenia Based on Transtheoretical Model: Seoyoun Park, Mee Ock Gu; J Korean Acad Nurs 2018;48(6):656-668. Published online January 15, 2018; DOI: https://doi.org/10.4040/jkan.2018.48.6.656

Abstract PDF: Abstract Purpose
The purpose of this study was to develop and examine the effects of combined exercise program for older adults with sarcopenia based on transtheoretical model (TTM).
Methods
A non-equivalent control group with a pretest-posttest design was used. The subjects consisted of 43 older adults with sarcopenia in precontemplation stage, contemplation stage and preparation stage of TTM (experimental group: 22, control group: 21). The developed program consisted of 36 sessions for 12 weeks including combined exercise (60 minutes) and TTM based strategies for enhancing exercise behavior (10 minutes) per session. Data were collected before, immediately after the program between July 31 to October 27, 2017. The data were analyzed using independent t-test, Mann-Whitney U test with SPSS/WIN 18.0.
Results
Compared with their counterparts in the control groups, older adults with sarcopenia in the experimental group showed a significantly greater improvement in process of exercise behavior change, pros and cons of decisional balance for exercise behavior, exercise self-efficacy, parameters of muscle, and the level of physical performance.
Conclusion
The study findings indicate that this combined exercise program for older adults with sarcopenia based on TTM model was effective and can be recommended as a nursing intervention for older adults with sarcopenia.
