简要总结
This pilot randomized controlled trial (RCT) will examine the effect of a tailored workplace intervention based on interrupting sitting on work productivity, well-being and cardio-metabolic risk in office workers. The experimental group in the 8-week intervention will be prompted to alternate between sitting and standing while working. The ratio between sitting and standing will begin at 3:1 (two hours per day in an eight-hour day) and increase to 1:1 (four hours per day in an eight-hour day) by the end of the second week of the eight-week intervention.

研究组 & 干预措施
Breaking up sitting time
A behaviour-change intervention to break up prolonged sitting in the workplace
干预措施: Breaking up sitting (Behavioral)
Control
The participants in the control group will continue their daily activities as normal without any form of information about the intervention.
结局指标
主要结局
Change in sitting time (objective)
时间窗: Change from baseline sitting time at 8 weeks
Evaluation of change in sitting time in the workplace using wearable accelerometers (ActivPAL3; PAL Technologies Ltd., Glasgow, UK). The ActivPAL will be worn on the right thigh.
Change in physical activity level (objective)
时间窗: Change from baseline physical activity level at 8 weeks
Evaluation of physical activity time in the workplace using wearable accelerometers (ActivPAL3; PAL Technologies Ltd., Glasgow, UK). The ActivPAL will be worn on the right thigh.
Change in sitting time (subjective)
时间窗: Change from baseline sitting time at 8 weeks
The International Physical Activity Questionnaire (IPAQ) will be used to provide a subjective measure of sitting. The scale provides a measure of reported sitting time in minutes.
Change in physical activity level (subjective)
时间窗: Change from baseline physical activity level at 8 weeks
The International Physical Activity Questionnaire (IPAQ) will be used to provide a subjective measure of physical activity level. The scale provides a measure of reported sitting time in minutes for each of three types of physical activity (vigorous, moderate, and walking).
