  1. Abbreviations: BMI, body mass index; DBP, diastolic blood pressure; PAPS, physical activity promotion system; SBP, systolic blood pressure; WC, waist circumference; WHtR, waist-to-height ratio. Data are expressed as mean±s.d. or number (%). Statistics were analyzed using the Student’s t-test and chi-square test.
  2. Higher PAPS scores indicate a better fitness level. Higher dietary habit scores indicate the presence of more desirable habits.
  3. an=349 (control) and n=418 (intervention).
  4. bn=349 (control) and n=414 (intervention).
  5. cn=345 (control) and n=408 (intervention).
  6. dn=348 (control) and n=385 (intervention).
