Background: Relative age effect is defined as a phenomenon where children born early generally perform better than children born later in the same cohort. Physical activity is an important factor that mitigates the relative age effect. Socioeconomic factors (e.g., parent’s income, education level) are also associated with the adolescent’s physical...
