Table 4

Time-dependent changes in total and brisk-walking step counts in the intervention group.

	Baseline	6 months	9 months	15 months	value
Total steps	7171 (6087 to 8256)	10121 (9120 to 11121)	8697 (7743 to 9650)	8652 (7796 to 9508)	<0.001
Brisk walking	2217 (1422 to 3012)	3413 (2553 to 4273)	2927 (2090 to 3764)	2711 (2039 to 3382)	<0.001

Values are means (95% CI).
P value < 0.05: repeated measures ANOVA were compared with the baseline using Bonferroni’s post hoc tests. Greenhouse-Geisser correction is 0.78.
Brisk walking was defined as continuous walking for ≥10 min at a pace equivalent to ≥4 metabolic equivalents.
