Associations of physical activity intensity and specific sedentary behaviors during after-school and weekend with overweight and obesity among preschool children.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThis cross-sectional study examined the association between physical activity (PA) intensity and specific sedentary behaviors (SB) among preschool children with overweight or obesity.
methodsA sample of 1,115 preschoolers aged 3-6 years in Taipei City was recruited from March to April 2022. Parents completed a validated, self-administered survey assessing the child's PA intensity (light [LPA], moderate-to-vigorous [MVPA]) and specific SB (total sedentary time [ST], screen-based sedentary time [SST], non-screen sedentary time [NSST], electronic game screen time [EST]). Child's height and weight were measured, and age- and sex-specific body mass index z-scores were calculated. Logistic regression was used in this study.
resultsOverall, 23% of the preschool children (age: 4.85 ± 0.91y; 49.9% female) were identified as having overweight or obesity. After adjusting for confounding factors, the highest quartile of total PA, LPA, and MVPA during the weekend was significantly associated with a lower risk of being overweight or having obesity compared with the lowest quartile. Furthermore, the highest quartile of ST and EST after school were associated with a higher risk of being overweight or having obesity compared with the lowest quartile.
conclusionsThe strategies to prevent overweight and obesity among preschool children should consider cumulative PA of any intensity during the weekend, even light PA. Moreover, decreasing screen time and playing video games after school might help prevent overweight/obesity.
