Prevalence of insufficient outdoor activity and caregiver-related correlates among school-aged children in Beijing, China: a cross-sectional analysis.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Daily outdoor activity time among school-age children worldwide is on a downward trend. This study updated the daily outdoor activity status of Chinese school-age children and analyzed the factors associated with insufficient outdoor activity among school-age children. Methods: This study utilized baseline data from a sugar-sweetened beverage consumption behavior cohort conducted among primary and secondary schools in Beijing, China. The baseline survey was conducted from October to November 2024, and 3,370 school-age children with complete data related to outdoor activity were included in the analysis. Binary logistic regression model was used to analyze the main factors associated with insufficient outdoor activity among school-age children. Results: The overall prevalence of insufficient outdoor activity was 82.9% among Beijing school-aged children (< 2 h/day).Residential location, grade, weight status, pre-activity beverage consumption patterns, and caregivers' daily outdoor activity duration were closely correlated with inadequate outdoor activity, with notable heterogeneity observed across residential area, gender and grade subgroups. Caregivers' limited outdoor activity participation emerged as the most stable correlate across all stratifications. Conclusion: This study reveals a high prevalence of insufficient outdoor activity among Beijing schoolchildren and identifies distinct population-specific associated factors. The findings provide empirical evidence for developing targeted subgroup interventions and optimizing family-school collaborative strategies to improve outdoor activity levels and promote long-term health among urban school-aged children.
