    %   
All PA groups 10.4 27.0 35.3 27.3 100
PA group 1 1.6 29.8 43.0 27.2 100
PA group 2 17.3 39.5 31.7 11.4 100
PA group 3 45.6 42.1 7.5 4.8 100
PA group 4 0.0 13.8 42.1 44.0 100
  1. Note. PA physical activity, TV television
  2. The probabilities above were estimated from a dual-trajectory analysis of physical activity and television viewing behaviors
  3. PA group label: 1 = substantially decreasing from high PA; 2 = maintaining moderate PA; 3 = maintaining high PA; 4 = decreasing from moderate PA
  4. TV group label: 1 = decreasing from moderate TV viewing; 2 = decreasing from high TV viewing; 3 = increasing from moderate TV viewing; 4 = increasing from high TV viewing
