CFMIN/DF = chi-square statistics/degrees of freedom; RMSEA = root mean square error approximation; AIC/BCC = Bayesian parameters AIC and BIC; SRMR, CFI and TLI = standards and comparative indexes of model adequacy. PE = physical education; SED =Sedentary time; HQOL = health-related quality of life; MVPA = moderate and vigorous physical activity; PA = physical activity: Factor weights with significant values P < .05a. SEM = structural equation model.
