Data are presented as mean±SD or n (%). Physical activity is based on the American Heart Association Life's Simple 7.
Poor health is defined as 0 min of moderate and vigorous physical activity.
Intermediate health is defined as 1 to 149 min of moderate physical activity, 1 to 75 min of vigorous activity, or 1 to 149 min of combined moderate and vigorous physical activity.
Ideal health is defined as ≥150 min of moderate physical activity, ≥75 min of vigorous physical activity, or ≥150 min of combined moderate and vigorous physical activity.
Incident coronary heart disease excluding missing values (n=3862).
