Purpose - This study surveys factors such as lifestyles, nutritional status, physical indicators, and physical fitness levels that affect the health of seniors over the age of 65 and based on the collected data attempts to create a senior health index model that provides health service information, help support seniors’ successful aging, and improve their quality of life.
Research design, data, and methodology – This paper conducted the development for senior health index model and the cross validity verification to examine the status of senior health level, and aimed at setting the health status evaluation criteria. Seniors 384 usable data were analyzed.
Results – As an attempt to segment the senior health service market, I divided the results of this study based on measurability, accessibility, disparity between groups, and the size of the potential client base. I divided the senior market into five subgroups: very healthy, healthy, normal, weak, and very weak.
Conclusions - The findings of this study may prove useful in preparing for the forthcoming super-aged society through segmentation of the senior market, understanding differences between groups with different health conditions, and discovering effective marketing strategies that meet the demands of different senior groups.
