Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sedentary behaviour and physical inactivity are risk factors for noncommunicable diseases related to the work environment. The accumulation of sitting time during the workday is related to musculoskeletal symptoms and worse cardiometabolic indicators.

The purpose of this study is to determine the effect of the "Stand up for your Health®" computer app on sitting time, musculoskeletal symptoms, cardiometabolic markers, and physical activity in office workers. Also, to determine the adherence to the intervention program by identifying barriers and facilitators referred by the participants.

In this 2-arm randomized controlled trial, both groups will be recruited from educational establishments and will be measured at baseline, 3rd, and 6th months. The experimental group will be implementing the "Stand Up for Your Health®" computer app plus educational information, while the control group will only receive educational information.

The same measurements will be completed in both groups during a 6 months follow-up period: sedentary behaviour using the Actigraph accelerometers and the Occupational Sitting and Physical Activity Questionnaire (OSPAQ); musculoskeletal symptoms will be assessed by a pressure pain algometer and the Standardized Nordic Questionnaire of Perception of musculoskeletal Symptoms; and cardiometabolic markers and anthropometric measurements will also be assessed according to protocol.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Randomized parallel-group trial. The groups will be recruited from higher education institutions. The length of this study will be six months. Measurements shall be made for both groups at baseline, 3rd, and 6th months.

The intervention group will receive the computer prompt "Stand up for your Health®" and information about sedentary behaviour. The computer prompt appears when the workers accumulate one hour the work front to screen. The break is two minutes, and one video with exercises starts with instructions for workers during this time.

The control group will receive only information through the leaflet.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Computer prompt + Education (CP+E)

The intervention group consists of the implementation of the desktop application "Stand up for your Health®" following the model proposed by the Guide to Physical Activity at Work plus education through an information leaflet

Group Type EXPERIMENTAL

Computer prompt "Stand up for your Health®"

Intervention Type BEHAVIORAL

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.

Only Education (OE)

The control group will receive only education through an information leaflet also following the guidelines of the Work Physical Activity Guide on indications to control the time sitting at work.

Group Type NO_INTERVENTION

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* office workers over 18 years of age,
* Full-time employees (≥35 hours per week);
* Spend most of their workday sitting (\> 60%). This will be initially self-reported and used as selection criteria prior to the initial consent and measurement visit. This will be later confirmed using accelerometers;
* Work in the same office place during the week; and
* Able to walk without using an assistive device or requiring the assistance of another person.
