Overview
Brief 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.

Outcomes
Primary Outcomes
Sedentary behavior
Time Frame: 16 weeks
Sedentary behavior will be assessed trough the sitting time (min/day) given by ActivPALTM micro device (PAL Technologies Limited, Glasgow, UK). The device will be attached on anterior mid-line of the participants right thigh though 3MTM TegadermTM Transparent Film Roll (4 in x 11yd). Participants will wear the inclinometer continuously for seven days, including shower and sleep time, except in swimming activities. The ActivPAL3TM software v.7.2.32 will be used to data reduction. In addition to the baseline and follow-up measurements, the inclinometer will be used during the intervention just in school time to better clarify the sit-to-stand desks use.
