Abbreviations:PA Physical activity, MVPA Moderate-to-vigorous physical activity, CRF Cardio-respiratory fitness.
First number is partial correlation coefficients (r) from baseline measurements only. Second number is r from the average of all three seasons. Both are controlled for age, grade, gender and pubertal status.
r ≥ |0.09|: P < 0.05.
r ≥ |0.16|: P < 0.001.
1Screen time is only measured at baseline.
2When adjusted for MVPA: r = 0.08; p = 0.09.
