  1. The models were adjusted for age, height, marital status, education, and parental Mets.
  2. β represents the mean BP changes in males and females due to each follow-up examination, each unit changes in LTPA, and influential factors status.
  3. BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; LTPA, leisure time physical activity.
  4. Significant values are in [bold].
