The overall prevalence of insufficient outdoor activity was 82.9% among Beijing school-aged children (< 2 h/day), with caregivers' limited outdoor activity participation emerging as the most stable correlate across all stratifications.
The prevalence of insufficient outdoor activity (less than 2 hours per day) among Beijing school-aged children was 82.9%.
Caregivers' limited outdoor activity participation was the most stable correlate of insufficient outdoor activity across all stratifications.
Residential location, grade, weight status, and pre-activity beverage consumption patterns were all correlated with insufficient outdoor activity among school-aged children.
Daily outdoor activity time among school-age children worldwide is on a downward trend, providing context for the high prevalence found in Beijing.
The findings support developing targeted subgroup interventions and optimizing family-school collaborative strategies to improve outdoor activity levels.
This research found that more than 4 out of 5 school-aged children in Beijing (82.9%) are not getting the recommended minimum of 2 hours of outdoor activity per day. The study surveyed 3,370 children from primary and secondary schools in Beijing in late 2024, making it one of the more recent assessments of this issue in urban China. Factors linked to children getting too little outdoor time included where they lived, what grade they were in, their weight status, and what they drank before physical activity. However, the single most consistent factor across all groups examined was whether their caregivers (parents or guardians) were themselves physically active outdoors. The finding about caregivers is particularly notable because it held true regardless of the child's gender, grade level, or neighborhood. This suggests that children's outdoor habits are closely tied to the modeling behavior of the adults in their lives. The study also found that the specific factors associated with insufficient outdoor activity varied depending on whether children lived in urban or suburban areas, their gender, and their school grade, indicating that a one-size-fits-all approach to encouraging outdoor activity may be less effective. This research suggests that efforts to increase outdoor activity among urban Chinese children should involve both families and schools, and that interventions targeting caregivers' own activity habits may be especially important. The very high prevalence of insufficient outdoor activity is concerning given known links between outdoor time and children's health outcomes, including vision health and physical fitness. The findings highlight a need for strategies that are tailored to specific subgroups of children rather than general population-wide approaches.
