Introduction

: Reproducible instruments measuring physical activity and sedentary behaviors are a priority for monitoring and promoting healthy lifestyles for boys and girls. This study evaluated the test-retest reproducibility of the "Prevención de la Obesidad Infantil en Barcelona (Childhood Obesity Prevention in Barcelona) [POIBA]-How do we move?" questionnaire in Colombian school children.

Materials and methods

: One hundred twenty-five third-grade primary students from a public educational institution in Colombia participated in the "POIBA-How do we move?" questionnaire, which was conducted twice. The survey measured physical activity during travel to and from school, school hours (physical education classes and recess), extracurricular activities (sports with a coach), and leisure time. To assess reproducibility, categorical questions and questions with a quantitative scale were evaluated using kappa and weighted kappa indices and an intraclass correlation coefficient with a mixed-effects model.

Results

: In the questions about physical activity at school and sports practice, kappas higher than 0.70 predominated. The questions about commuting to and from school had kappa coefficients close to 0.90. The kappa coefficients for the screen-time questions were around 0.5, and the intraclass correlation coefficients for questions about going to bed and getting up were between 0.40 and 0.72.

Conclusions

: The "POIBA-How do we move?" questionnaire is a valuable tool for evaluating the physical activity of school children in a Latin American context. The questions concerning physical activity during commuting to and from school, school hours, and sports environment had the highest reproducibility indices.
