Physical activity patterns
There were no differences in groups over baseline days (Table 1). Sitting time during the intervention was 66.0 ± 137.1 min.day-1 higher for the PMW group compared to CTL (group: p = 0.02, Figure 2), however, time spent sitting in periods for more than 30 minutes at a time did not differ between groups over time (interaction: p = 0.50). Stepping time during the intervention was lower with PMW compared to CTL (by 14 min.day-1; group: p = 0.05, Figure 2). Mean time spent standing and activity score did not differ between groups over time (Table 1).
When groups were matched for pre-pregnancy BMI, outcomes were the same (as above).
