Effects of a Smartphone-Supported Daily Walking Intervention on Psychological Well-Being and Body Composition in Adults With Cardiometabolic Disease (DAILY-WALK)

June 23, 2026 updated by: Daiva Majauskiene, Klaipėda University

Psychological Benefits of Increased Daily Walking Precede Meaningful Changes in BodyComposition in Adults With Cardiometabolic Disease

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.

Detailed Description

This was a three-month quasi-experimental longitudinal study in adults aged 20 to 65 years with physician-confirmed cardiovascular disease and/or type 2 diabetes mellitus. The intervention was delivered through the Walk15 smartphone platform. Participants received individualized step goals based on baseline activity levels and were encouraged to increase daily walking gradually, aiming for approximately 1,000 additional steps per day. Daily step counts were monitored through smartphone-connected wearable devices and synchronized with the Walk15 platform. No dietary modifications, weight-loss program, or structured exercise training were prescribed. The study assessed changes in physical activity, psychological well-being, lifestyle behaviors, muscle strength, and body composition from baseline to the end of the three-month intervention.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Smartphone-Supported Daily Walking Intervention Arm Type
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
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.

Outcome Measure
Measure Description
Time Frame
Change in Daily Step Count
Time Frame: Baseline to 3 months
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
