A study on the influence of family social capital on participation in adolescent extracurricular sports and public health.

Introduction: With increasing academic pressure, extracurricular tutoring and interest classes are growing rapidly. This trend is especially evident in youth sports interest classes. Families allocate limited resources to these activities, directly influencing their social capital. This study examines how family social capital affects adolescent participation in extracurricular sports and its broader implications for public health. Methods: This study uses longitudinal data from the China Family Tracking Survey (CFPS, 2010-2018, Results: Adolescents from high-social-capital families had significantly higher sports participation (85%) than those from low-social-capital families (25%). They also had lower obesity rates (10% vs. 30%) and reduced anxiety and depression by 25% and 20%, respectively. Parental engagement increased the likelihood of sports participation by 15%, and educational resources positively impacted adolescent wellbeing. Regional disparities were evident, with urban adolescents participating at 70%, compared to 40% in rural areas. Discussion: The findings show that higher family social capital improves adolescents' physical and mental health. It helps reduce public health risks such as obesity, anxiety, and depression. Additionally, it increases the participation of young people in various physical activities. This study emphasizes the need to improve family social capital and address regional inequalities. These efforts can promote public health and provide equitable access to extracurricular opportunities.
