Brief Summary

This study evaluated whether a three-month smartphone-supported daily walking intervention could improve physical activity, psychological well-being, and body composition in adults with cardiometabolic disease. Participants had cardiovascular disease and/or type 2 diabetes and used the Walk15 smartphone platform to monitor daily step count. The intervention aimed to increase daily walking by approximately 1,000 steps per day through individualized step goals, self-monitoring, and digital feedback. Outcomes were assessed before and after the intervention and included daily step count, body composition, handgrip strength, sleep duration, eating behaviors, subjective well-being, vigor, stress, anxiety, health, and happiness.

Outcome Measures

Primary Outcomes (1)

• Change in Daily Step Count

  Daily step count was assessed using the Walk15 smartphone platform, which synchronized step-count data from participants' smartphones and wearable devices. Change was calculated as the difference between baseline daily step count and post-intervention daily step count.

  Baseline to 3 months

EXPERIMENTAL

Participants received a three-month smartphone-supported walking intervention delivered through the Walk15 platform. Individualized step goals were established based on baseline activity levels, and participants were encouraged to increase daily walking by approximately 1,000 steps per day. Daily step counts were monitored using smartphone-connected wearable devices and synchronized with the Walk15 platform.

Behavioral: Smartphone-Supported Daily Walking

Interventions

Smartphone-Supported Daily Walking BEHAVIORAL

Participants received a three-month smartphone-supported walking intervention delivered through the Walk15 platform. Individualized step goals were established based on baseline daily step counts. Participants were encouraged to increase daily walking by approximately 1,000 steps per day, progressing gradually during the first month. Daily step counts were monitored using smartphone-connected wearable devices and synchronized with the Walk15 platform. Participants received feedback through the platform to support adherence. No dietary modifications, weight-loss program, or structured exercise training were prescribed.
