Brief Summary

The aim of this study was to evaluate the impact of a classroom teachers' educational intervention on 1st and 2nd grades children's physical activity level and energy expenditure during physical education classes in elementary public schools, in São Paulo, Brazil.

Detailed Description

This study is a School-based Randomized Controlled Trial. Three-step cluster sampling was used for subject selection. In the first step, 8 schools in the Vila Mariana district - São Paulo were selected and assigned randomly to physical activity intervention (3 schools) or control condition (5 schools). In the second step, all 48 classes from the 1st and 2nd grades were selected. In the third step, 352 children were randomly selected compose the observational group. In both groups, questionnaire data and SOFIT's observation were collected two times: "pre" (immediately before the intervention), and "post" (immediately after the intervention), with a six weeks interval between them. No educational intervention was taken place in the control schools while the project was running. Afterwards control schools received training.

Study Groups

Educational Intervention

Intervention was applied to classroom teachers by the RRIDA Project team. Training lasted six weeks, 12 hours devoted to physical activity and 18 hours to nutritional content. Modules of educational activities were taught in order to be replicated at PE classes to 1st and 2nd grades' children of three exposed schools. Physical activity module was based on a theoretical approach of physical activity benefits and risks for health, children's physical fitness and activity patterns, physical education and change behavior models. In each meeting the PE professionals, performed PE classes with the classroom teachers as students, focusing in strategies to keep them in movement for the most of PE class time to stimulate students' joint participation instead of individual participation or games.

Group Type: EXPERIMENTAL

Educational Intervention

Intervention Type: BEHAVIORAL

Intervention was applied to classroom teachers by the multidisciplinary team of the RRIDA Project. Training lasted six weeks, 12 hours devoted to physical activity and 18 hours to nutritional content. Modules of educational activities to classroom teachers were to be replicated at PE classes to children from 1st and 2nd grades of three exposed schools. The physical activity module was based on a theoretical approach of physical activity benefits and risks for health, children's physical fitness and activity patterns, physical education and change behavior models.

No Intervention

No educational intervention was taken place in the control schools while the project was running. Afterwards, control schools received training.
