Summary

The goal of this randomized clinical trial is to determine the effect of the computer prompt to break sitting time in office workers.

The main question is: What is the effect of the computer prompt "Stand Up for Your Health®" plus education on sitting time, musculoskeletal symptoms, cardiometabolic markers, and physical activity in office workers compared with only education? In addition, to determine the level of adherence to the intervention program by identifying barriers and facilitators referred by the participants.

The participants will be divided into two groups, the experimental and the control group. The participants in the experimental group will use the computer prompt on their desktop and receive information about sedentary behaviour, and the control group will receive only information. All participants will wear accelerometers for one week. The musculoskeletal symptoms and cardiometabolic markers will be measured at baseline, 3rd and 6th month.

Interventions

BEHAVIORAL

Computer prompt "Stand up for your Health®"

The intervention group consists on the implementation of a desktop application "Stand up for your Health®" computer prompt following the model proposed by the Guide to Physical Activity at Work (34). This app works by showing reminders and asking users to pause their work activity and take an active break. Pauses can be customized and programmed according to the user's preference, allowing control of the time of each pause, between pauses, and the possibility of delaying or interrupting the pause. In this study, the "Stand up for your Health®" app will be scheduled to appear every 60 minutes on the workers' computers and each break will last for 2 minutes. During this resting period, the worker will see a notice or reminder on their screen with a countdown clock. The application allows you to postpone or interrupt directions.
