Interventions/Control_1
Participants in the intervention group will receive an intervention designed to support use of the Online Kayoinoba app. First, they will attend one standardized smartphone-use training session. They will then receive eight weekly face-to-face instructional sessions over the 8-week intervention period. At each visit, a specialist will provide a 60-minute lecture on the proper use of the Online Kayoinoba app and its functions. The content will include app installation, how to earn points, the walking function, exercise videos, dietary check, communication functions, health check, and an overall review of these functions. In addition, the same health education provided to the control group will also be delivered. After the intervention period, an approximately 67-week follow-up period will be conducted. During follow-up, a newsletter containing information useful for health and daily living will be mailed every 4 weeks to support continued study participation. In the intervention group, the in-app group chat will also be used once a week after Visit 9 to encourage participants to open the app regularly.
Interventions/Control_2
Participants in the control group will first receive one smartphone-use training session identical to that provided to the intervention group. They will then attend eight weekly visits over the 8-week intervention period to receive health education. The educational content will cover frailty awareness, exercise, nutrition, sleep, social participation, and a general review related to frailty prevention and management. After the intervention period, participants will enter an approximately 67-week follow-up period. During follow-up, a newsletter containing information useful for health and daily living will be mailed every 4 weeks to support continued study participation. To minimize contamination, face-to-face instructional sessions will be conducted separately for the intervention and control groups.
