Brief Summary

The Children Sit Less, Move More (C-SLAMM) study aims to test the feasibility and potential effect of a multi-component school and home-based pilot cluster randomized control trial on reducing sedentary behavior and increasing physical activity in children.

This pilot intervention will be an 8-week two-armed cluster RCT. Individuals (children aged 7-9 years) will be the unit of analysis and schools (cluster) randomly assigned to one of two arms: (1) Physical activity and sedentary behavior (intervention arm), or (2) current practice (control arm). The design conduct and reporting of the intervention with adhere to the Consolidation Standards of Reporting Trials (CONSORT) guidelines and is guided by the Standard Protocol Items for Randomized Trials (SPIRIT) Statement.

Detailed Description

The C-SLAMM study is an 8-week school-and home-based feasibility, two-armed pilot cluster randomized controlled trial.

A convenience sample of primary schools in Northern Ireland will be invited to take part in the study. Baseline measurements will proceed randomization, and an identical set of measures will be taken from participants in week 8 of the intervention.

Individuals (Primary 4 and Primary 5 children, aged 7-9 years) will be the unit of analysis and schools (clusters) will be randomly assigned to one of two conditions: (1) intervention condition or (2) current practice (control condition). Given the nature of the intervention, blinding of schools and participants will not be possible following randomization. The researcher responsible for subsequent data collection and analysis will not be blinded to group allocation. Any differences between the intervention and control groups will be by chance and adjusted for in the analyses. Schools randomized to control will be offered information on the intervention and associated materials at the end of the intervention.

The intervention is, adapted from the previously tested Transform-Us! trial and informed by a qualitative study was on the perceived barriers and facilitators of physical activity within the classroom, school and/or home environment (REC/20/0033).

The C-SLAMM study will use innovative behavioral, pedological, and environmental strategies within the classroom, school, and home settings to get children moving more and sitting less. Resources include health lessons, active lessons, active breaks, active homework to do with parents, active environments, and newsletters for parents. Each week teachers will be advised to incorporate elements of the intervention within the classroom setting. Teachers will modify the delivery of at least one class lesson per week (\~30 minutes) so that children will complete the lesson standing up. Teachers will be provided with a suite of standing lesson delivery methods that can be modified to any class topic. In addition, every two-hour classroom teaching block will be interrupted every 30 minutes with a 2-minute guided light-intensity activity break. This will equate to a total of six minutes interrupted sitting time every two hours. Furthermore, each class will be provided with six standing desks so that children can rotate learning activities at 'standing stations'. A novelty timer will be given to each class so that teachers can monitor 2-minute standing breaks and every 30-minutes of sitting class time.

To compare the effects of the intervention against usual practice, schools assigned to the control arm will be requested to continue with their usual practice and lesson delivery, no environmental changes will be made to their classrooms. The participants in the control schools will be asked to complete the same study measurements as those in the intervention schools at the same time points.
