Brief Summary

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

In this trial the investigators aim to verify the potential impacts of a multi-level intervention with standing desks on behavior and cognitive function in children

Detailed Description

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

This is a cluster controlled trial conducted in a school setting. Two classes (intervention and control) of sixth grade will be selected from a large, centrally located school in Lisbon. The intervention will take place over a period of 16 weeks and will be composed of physical environmental (standing desks), social environment, and education/behavior components. Objective measurements of physical activity and sedentary behavior (ActiGraph GT3X+ accelerometer and activPAL inclinometer), school performance (students grades), attention (D2 test), memory (Rey complex figure), fluid intelligence (Raven's Progressive Matrices), visuo-spatial short term working memory (Corsi block-tapping test), processing speed and inhibitory function (Stoop test) will be assessed. Finally, anthropometry and stakeholders' perceptions will also be obtained at baseline and after the intervention.

Study Groups

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

Intervention

Sit-to-stand desks (Ergotron LearnFit®) will replace standard desks. In addition, meeting with parents and teacher's training will be conducted in order to support behavior change.
