1
All values are mean ± SE. EU, exercise units calculated on the basis of frequency and intensity of activity.
2
Sex-by-time interaction for walking score, P = 0.02 (likelihood ratio test).
3
Within sex, P for trend < 0.05.
4
Significantly different from men, P < 0.05 (t test).
5
Main effect of time within sex, P < 0.00001 (one-factor ANOVA).
