The aim of this study was to test the short-term efficacy of the Sit Less, Walk More (SLWM) workplace intervention.
This was a quasi-experimental design. A total of 99 office workers from two workplaces participated in this study. The 12-week intervention included five components: monthly newsletters, motivational tools, pedometer challenge, environmental prompts, and walking route. The comparison group received monthly newsletters only.
Generalized estimating equation analyses showed that the intervention group demonstrated significant improvements in weight (P = 0.029), waist circumference (P = 0.038), diastolic blood pressure (P < 0.001), walking (P < 0.001), moderate-intensity physical activity (P = 0.014), and total physical activity (P
= 0.003) relative to the comparison group. A significant improvement in lost-productivity was observed in both groups (P
= 0.003 to 0.008).
The SLWM workplace intervention can improve worker health and lost-productivity.
