Summary

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

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.
