Effectiveness of an Information-Motivation-Behavioral Skills Model-Based Sarcopenia Prevention Program for Older
Purpose:
To evaluate the effectiveness of an information-motivation-behavioral skills (IMB) model-based sarcopenia prevention program.
Method:
A quasi-experimental study was conducted with 50 older adults from senior centers in South Korea, divided into experimental (n = 25) and control (n = 25) groups. The 12-session intervention program spanned 6 weeks, comprising structured physical activity exercises, nutritional education focusing on protein and vitamin D intake, and motivational strategies aimed at sustaining behavior change. Data were analyzed, applying logistic regression, t tests, and Mann-Whitney U tests for group comparisons.
Results:
The experimental group showed significant improvements in physical performance (odds ratio [OR] = 2.37, 95% confidence interval [1.42, 107.74], p = .002) and sarcopenia-related quality of life (t = 8.02, p < .001). However, no significant changes in muscle mass (OR = 3.12, p = 1.000) or muscle strength (OR = 2.00, p = .153) were observed.
Conclusion:
The IMB model-based program improved physical performance and quality of life in older adults, making it a viable nursing intervention for sarcopenia prevention. Further studies should explore long-term adherence and intervention effectiveness over extended periods.
