Prevalence of Sedentary Behavior and Physical Inactivity Among High School Students in Shenzhen

This study investigates the prevalence and structural drivers of sedentary behavior and physical inactivity among high school students in Shenzhen, China. Drawing on observational data, policy documents, and interviews with students, teachers, and parents, the research reveals a complex interplay between academic pressure, urban infrastructure, gender norms, and institutional practices. Despite the existence of national physical education mandates and an expanding network of public sports facilities, students—particularly girls and those from migrant or low-income backgrounds—face significant barriers to meaningful physical engagement. The school timetable, exam-centered culture, limited after-school offerings, and socio-spatial inequality in facility access all contribute to entrenched patterns of stillness. Gender and family expectations further constrain activity, while urban planning fails to prioritize adolescent needs. The study proposes a multi-level intervention strategy, emphasizing curricular reform, community collaboration, and inclusive urban design to foster a more active and equitable environment for youth development in China’s rapidly urbanizing educational context.
