Office workers’ experiences of attempts to reduce sitting-time: an exploratory, mixed-methods uncontrolled intervention pilot study

Table 3 Sitting, standing and stepping time (in mins) per 8 h workday, across study timepoints

	Baseline (−1–0 weeks) N = 29	Post-intervention 1 (0–1 weeks) N = 21			Post-intervention 2 (5–6 weeks) N = 18			Post-intervention 3 (11–12 weeks) N = 16

^aMean differences from baseline pertain to participants for whom data were available at each timepoint. For this reason, values do not correspond to the difference between the mean of each baseline timepoint (Ns < 29) and the baseline mean where N = 29
