INTRODUCTION:
Previous school-based interventions have addressed adolescent health behaviors such as physical activity during leisure time, screen time, and sleep but have predominantly targeted these behaviors independently rather than simultaneously (Salam, 2016; Oh et al., 2022). The Erasmus+project FITeens introduced digital tools designed to target all three behaviors concurrently using theoretical content, videos, infographics, and interactive tasks (Garcia-Gonzales et al., 2021). This study aims to evaluate the effectiveness of a school-based intervention incorporating FITeens digital tools to promote physical activity, reduce screen time, and enhance sleep in adolescents.
METHODS:
Prior to delivering the intervention to 5–9th grade students, teachers will be introduced to the digital tools. Students will undergo an eight-week
intervention comprising lessons delivered by teachers on health-related topics combined with behavior challenges provided through the FITeens
smartphone application. Students will complete questionnaires assessing behavioral intentions and motivation related to healthy sleep habits, screen time, physical activity, and sedentary behaviors at baseline and at one-, three- and six-month follow-up.
RESULTS:
It is expected that the intervention program will show significant improvements in physical activity levels and sleep quality, as well as a
reduction in screen time, with enduring effects at three- and six-month follow-up.
CONCLUSION:
The FITeens-based intervention could promote healthier lifestyle behaviors among students by increasing physical activity during leisure time and supporting the effective limitation of screen time and bedtime routines
