  1. Note: Means in the same row having letters that do not share subscripts differ at p < .01 in the Tukey-Kramer honestly significant difference test. The higher the physical activity score, the greater intensity and amount of reported exercise over the past 30 days using a scoring system of 0 (do not participate regularly in planned exercise) to 7 (spend over 3 hours weekly in heavy exercise).
