Co-Creating Active Middle School Communities to Increase Student Physical Activity

Physical Activity

physical activity, adolescent health, active transport, active leisure, middle school

The purpose of this study is to identify community-level barriers and facilitators for active transport and leisure physical activity and to co-create and test the effectiveness and longer-term sustainability of community-based physical activity intervention strategies in middle schools. Participation in this study may help the investigators and scientific community better understand and address child physical activity and health. This study will collect information about middle school children's physical activity behaviors, habits, knowledge, and activity. The UTHealth School of Public Health is leading the study together with the University of Texas at Austin.

Early adolescence is a critical window of opportunity for establishing lifelong physically active lifestyles. During this stage, youth seek autonomy and experience independent mobility. However, steep declines in physical activity occur in adolescence, a trend that continues into adulthood. This is partly due to reduced opportunities for structured exercise and sports in later life relative to childhood. Despite this, most school-based interventions heavily focus on physical education, sports participation, and active recess strategies (i.e., leisure), with less emphasis on promoting utilitarian (transport-based) physical activity. Interventions prioritizing the entire school community (including students, their families, and school neighborhood residents), and focused on increasing active transport and leisure, might have a more significant and sustainable impact over the lifespan. To be effective and contextually responsive, however, intervention development, implementation, and evaluation must be collaboratively conducted with and through local community members. This project proposes to conduct a comprehensive and community-engaged mixed methods study to design and test strategies for improving community-wide and individual-level physical activity outcomes in middle school neighborhoods. The specific aims of this study are: Aim 1. To identify community-level barriers and facilitators for physical activity in middle school communities using a comprehensive mixed methods approach (Delphi method with Group Concept Mapping, geospatial analysis, participatory GIS). Aim 2. To engage multi-sectoral and multi-generational community actors for co-creating contextually-responsive intervention strategies to improve access to active transport and leisure in middle school communities. Aim 3. To conduct a first-generation, controlled trial testing the effectiveness of the co-created intervention strategies for improving physical activity outcomes in middle school communities. Hypothesis 3.1. 12-month pre-post change in daily minutes of moderate- to vigorous-intensity physical activity (MVPA) will be higher among middle school students (grades 6-7) in school communities that implement co-created strategies relative to comparison school communities. Hypothesis 3.2 (exploratory). Community-based physical activity levels will improve at 12 months in intervention school communities, relative to comparison school communities. Hypothesis 3.3. (exploratory). The intervention will improve community-level outcomes, including enhanced community norms regarding active travel, collective efficacy for physical activity, and perceived neighborhood traffic and crime safety. If successful, these strategies can be scaled up to help increase physical activity among middle school children and communities in the U.S. Increased physical activity among middle school youth can lead to higher levels of physical activity throughout the lifespan, potentially decreasing or attenuating chronic diseases.
