Impact of wearable fitness technology on adolescent physical activity engagement and health literacy in schools: A longitudinal study

Project Abstract

This longitudinal mixed-method study investigates how wearable fitness technology influences adolescent physical activity engagement and health literacy within school settings over one academic year, integrating quantitative activity metrics with qualitative insights from students, teachers, and parents. The study employs a randomized cluster design across multiple secondary schools, enrolling 1,200 students aged 13–18 who are provided with standardized wearable devices, accompanied by school-wide curricula on physical education, digital health literacy, and self-monitoring strategies. Quantitative data include daily step counts, active minutes, heart rate zones, device wear-time adherence, and changes in moderate-to-vigorous physical activity (MVPA), collected via the wearables and corroborated with accelerometry. Health literacy is assessed through validated instruments measuring knowledge of physical activity guidelines, interpretation of wearable feedback, risk awareness, and decision-making skills regarding safe exercise practices. Secondary outcomes capture psychosocial determinants such as motivation, self-efficacy, perceived social support, and perceived autonomy, along with academic performance indicators relevant to health education. The qualitative strand comprises semi-structured interviews and focus groups with a purposive sample of students (n?60), PE teachers (n?12), and parents (n?20), complemented by classroom observations. Thematic analysis explores experiences with wearable technology, perceived barriers and facilitators to sustained activity, data literacy, privacy concerns, and the role of teacher-led facilitation in shaping engagement. The study also examines equity considerations, including device usability across diverse socioeconomic backgrounds, access to home resources, and potential disparities in intervention impact. Data analysis plans include multilevel modeling to account for clustering by school and classroom, growth curve analyses to track trajectories of activity and health literacy over time, and mediation/moderation analyses to identify mechanisms (e.g., self-efficacy, goal-setting, and social support) through which wearables influence outcomes. Qualitative data will be analyzed using a grounded theory approach to illuminate contextual factors and generate actionable themes for program refinement. Process evaluation will document implementation fidelity, adherence to privacy and safety protocols, and teacher professional development needs. Expected findings indicate that regular use of wearables, coupled with structured health literacy modules and supportive teacher facilitation, will lead to sustained increases in MVPA and enhanced health literacy skills, with larger effects among students who perceive higher autonomy and social support. Potential challenges include device fatigue, data overload, privacy concerns, and unequal access to external environments for activity tracking. The study aims to provide evidence on the feasibility, effectiveness, and equity implications of integrating wearable fitness technology into school-based health education, offering actionable recommendations for policy makers, educators, and technology developers to optimize adolescent health outcomes through scalable, literacy-enhanced, and youth-centered interventions.

Project Overview

What This Project Is About

---

A plain-language overview of how wearable fitness devices can influence how hard teens move during school hours and what they learn about staying healthy. The project follows a group of students over time to see if using wearables (like step counters or heart-rate bands) helps them be more active and understand health information better.

The Problem It Addresses

---

Youth physical activity often drops after early adolescence, and many students miss out on health facts that help them make better choices. There’s limited evidence on whether wearables in schools improve both activity levels and health literacy (the ability to understand health information). This project aims to fill that gap.

Objectives of the Project

---

1. Assess changes in daily physical activity after introducing wearables in school.
2. Evaluate improvements in students’ understanding of health concepts.
3. Explore students’ attitudes toward using wearable devices.
4. Identify factors that help or hinder the effectiveness of wearables in schools.

What You Will Do Step by Step

---

1. Review relevant literature on wearables, youth activity, and health literacy.
2. Obtain ethical approval and consent from school and participants.
3. Recruit a sample of students and provide wearables for a set period.
4. Collect data on activity (steps, active minutes) and health literacy scores through surveys.
5. Monitor device usage and engagement with health information materials.
6. Analyze changes over time and look for patterns related to demographics.
7. Interpret results in practical school settings and discuss limitations.
8. Prepare a report with recommendations for schools and policymakers.

Expected Outcome

The project is expected to show whether wearables can boost teens’ daily activity and their ability to understand health information, with practical guidance for implementing such tech in schools and for improving youth health outcomes.
