This study aimed to examine changes in health awareness and behavior among participants of a community-led health promotion program, "InBody Challenge 2024", conducted in Nayoro City, Hokkaido. A total of 108 adult residents participated in the program, and body composition measurements were taken before and after the intervention using the InBody470 device. Participants also voluntarily engaged in lifestyle improvements such as increased physical activity and dietary modifications according to their individual needs.
At the conclusion of the program, a structured questionnaire—including both multiple-choice and open-ended items—was administered to evaluate participants’ experiences and perceived changes. Results showed that over 80% of participants reported enhanced health awareness, and nearly all expressed a desire to maintain their health-related efforts beyond the program. Reported behavioral changes included increased awareness of weight and fat management, improved dietary habits, and the establishment of regular exercise routines, suggesting overall lifestyle improvements. A key strength of the program was its use of visualized physical data, which appeared to reinforce intrinsic motivation through enhanced self-efficacy.
Gender-based analysis revealed greater improvements among male participants, while a relatively higher proportion of female participants reported little or no improvement, indicating the need for more gender-sensitive support strategies. Additionally, open-ended responses highlighted the value of personalized feedback and interest in digital tools such as mobile health applications.
These findings suggest that community-based programs integrating measurement feedback, peer support, and tailored interventions can effectively promote sustainable health behavior change.
