  1. Values weighted to provide nationally representative estimates and presented as mean (SE). MVPA = moderate-to-vigorous physical activity; UODA = usual occupational/domestic activity; LTSB = leisure-time sedentary behavior.
  2. aSignificantly different from < 150 minutes/week of MVPA at p < 0.0018.
  3. bSignificantly different from “mostly sitting” UODA at p < 0.0018.
  4. cSignificantly different from ≥ 3 hours/day of LTSB at p < 0.0018.
