Longitudinal changes and tracking of in-school physical activity in primary school children: four-year longitudinal study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere is little evidence on the tracking of physical activity during school hours. In addition, tracking physical activity in schools provides important evidence for understanding children's physical activity and conducting intervention studies. Therefore, this study examined longitudinal changes and tracking of in-school physical activity in primary school children.
methodsIn this study, physical activity was investigated longitudinally in primary school children for 4 years. The baseline participants consisted of 103 second-grade students (7-8 years old) who participated. Step counts and moderate-to-vigorous physical activity (MVPA) in school and during first recess and lunch/second recess were examined using an accelerometer (Kenz Lifecorder GS 4-second version; Suzuken Co. Ltd, Nagoya, Japan).
resultsAfter excluding missing data (moving school; n = 8, physical activity; n = 8), 87 (43 boys and 44 girls) of whom were included in the final analysis. Step counts and MVPA during school and physical education in boys did not decrease across the school years. By contrast, in girls, step counts during school did not decrease across the school years, however MVPA did decrease. In addition, for both sexes, step counts and MVPA during first recess decrease across the school years. During lunch/second recess, only step counts decrease across the school years in both sexes. In addition, the tracking coefficients for step counts and MVPA for boys in school and during first recess and lunch/second recess were found across many school years. Contrarily, girls had fewer significant tracking coefficients between school years than boys. There were also few significant tracking coefficients between grades for physical education step counts and MVPA for both boys and girls.
conclusionsOur results suggested that in-school step counts for both boys and girls does not decrease across the school years. However, given that girls demonstrated reduced levels of in-school MVPA across the school years, it is important to promote strategies to increase MVPA in this group.
