  1. Significant values are in bold.
  2. BMI Body mass index, BPD Bronchopulmonary dysplasia, MVPA Moderate to vigorous physical activity, VPA vigorous physical activity. Bronchopulmonary dysplasia was defined as oxygen use at 36 weeks postmenstrual age. Data are expressed as mean ± SD. Comparisons between full-term vs preterm group were done by linear regression or Fisher’s exact test. *P-value < 0.05.
