Purpose
This study aimed to develop and evaluate the effectiveness of a health management program using a mobile application for middle-aged men experiencing andropause. Methods: A quasi-experimental design with a non-equivalent control group pretest-posttest structure was employed. The study took place from June 27 to August 30, 2024, with participant recruitment occurring from June 27 to July 10, 2024. In total, 61 participants (30 in the experimental group and 31 in the control group) participated from July 15 to August 20, 2024. The experimental group received an application-based health management program, while the control group did not. Results: The experimental group showed significant improvements in subjective quality of life, health-promoting behaviors, and subjective health status compared to the control group (p<.001). Conclusion: This study confirms that mobile applications can effectively manage health during andropause in middle-aged men. Further research with a larger sample size is recommended to validate these findings.
