The aim of this study was to test the short-term efficacy of the Sit Less, Walk More (SLWM) workplace intervention.Methods:
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.Results:
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).Conclusions:
The SLWM workplace intervention can improve worker health and lost-productivity.
