  1. aStudy visits occurred in time according to the gestational age of participants
  2. bFor walking, jogging, running, and cycling, METs were based on speed when distance and duration were provided. Assigned values are shown below
  3. Walking
  4. no speed (general) = 3.5 METs
  5. < 2.0 mph = 2.0 METs
  6. 2.0–2.4 mph = 2.8 METs
  7. 2.5–2.7 mph = 3.0 METs
  8. 2.8–3.5 mph = 3.5 METs
  9. 3.6–4.2 mph = 5.0 METs
  10. 4.3–4.9 mph = 7.0 METs
  11. ≥ 5.0 mph = 8.3 METs
  12. Jogging/Running
  13. jogging no speed (general) = 7.0 METs
  14. running no speed (general) = 8.0 METs
  15. < 4.9 mph = 6.0 METs
  16. 5.0–5.9 mph = 9.0 METs
  17. 6.0–6.9 mph = 11 .0 METs
  18. 7.0–7.9 mph = 11.5 METs
  19. 8.0–8.9 mph = 12.0 METs
  20. 9.0–9.9 mph = 12.8 METs
  21. ≥ 10 mph = 15.0 METs
  22. Cycling
  23. no speed (general) = 7.5 METs
  24. < 6.0 mph = 3.5 METs
  25. 6.0 - 9.9 mph = 5.0 METs
  26. 10.0 - 11.9 mph = 6.8 METs
  27. 12.0 - 13.9 mph = 8.0 METs
  28. 14.0 - 15.9 mph = 10.0 METs
  29. 16.0 - 19.9 mph= 12.0 METs
  30. ≥ 20.0 mph = 15.8 METs
