Table 4 Physical activity data from the International Physical Activity Questionnaire (IPAQ) at baseline and 12 weeks for the control and pedometer groups

Variable	Pedometer		Control		P-value
	Baseline	Week 12	Baseline	Week 12	Week 12
Walking (MET·min/wk)	244.5 ± 122.2	589.3 ± 167.2* ^a	224.6 ± 102	201.4 ± 114.6^b	0.036
Moderate activity (MET·min/wk)	161.5 ± 44.5	214.3 ± 67.5	177.2 ± 45.5	174.6 ± 54.5	0.234
Vigorous activity (MET·min/wk)	57.8 ± 34	59.5 ± 26	62.8 ± 23.3	61.3 ± 138.3	0.146
Total activity (MET·min/wk)	365.8 ± 195.4	689 ± 295.5	455.8 ± 203.5	389 ± 175.5	0.274

Values are represented as mean ± s.e.m
P-values represent the between group comparison of the control vs pedometer group at week 12.
There were no significant differences at baseline between groups.
*Significant difference (P < 0.05) within group (Baseline versus 12 weeks)
Significant difference (P < 0.05) between control group and pedometer group at 12 weeks is indicated by different letters.
