2. Figure
Trajectories of physical activity (PA) in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Plotted lines represent the trajectory class identified for the estimated pattern of PA scores by age and number of CARDIA participants in each class. Trajectory 1 is defined as below PA guidelines (n=1813; 57.1%); trajectory 2, meeting PA guidelines (n=1094; 34.5%); and trajectory 3, 3 times PA guidelines (n=268; 8.4%).
