This cross-sectional study of 965 rural-origin university students in Southwest China found that physical activity was associated with reduced social anxiety through both direct effects and indirect pathways mediated by body image satisfaction and social capital. The statistical analysis revealed that while physical activity had a direct negative association with social anxiety (accounting for 55.5% of the total effect), additional indirect pathways operated through improved body image satisfaction (16.5%), increased social capital (18.0%), and a sequential combination of both factors (10.5%). However, the overall association was modest, with limited clinical significance as a standalone intervention.
Why it matters
The findings suggest that interventions aimed at reducing social anxiety in rural-origin university students should adopt a multi-component approach rather than focusing solely on increasing physical activity. Understanding these mediating pathways can help universities develop more effective, culturally-sensitive mental health programs that address body image perceptions and social connectedness alongside physical activity promotion.
Understand the Science
BackgroundRural-origin university students in China face distinct psychosocial challenges, with social anxiety being particularly prevalent. Although physical activity is consistently associated with reduced social anxiety, its underlying mechanisms in this population remain unclear, especially regarding the potential statistical mediating roles of body image satisfaction and social capital.MethodsA cross-sectional survey of 965 rural-origin undergraduates was conducted in Yunnan Province, China. Validated instruments assessed physical activity, body image satisfaction, social capital, and social anxiety. Correlation, regression, and associative mediation analyses tested direct and indirect associations.ResultsPhysical activity showed a direct negative association with social anxiety (55.5% of total effect). Three indirect pathways emerged: via body image satisfaction (16.5%), via social capital (18.0%), and a sequential pathway (physical activity → body image satisfaction → social capital → social anxiety; 10.5%). The overall association was modest (unstandardized coefficient = −0.016 for item-average scores), suggesting limited standalone clinical utility.ConclusionPhysical activity is associated with lower social anxiety among rural-origin university students through both direct and indirect pathways. Body image satisfaction and social capital serve as critical statistical mediators–independently and sequentially. These findings support integrated, context-sensitive interventions addressing psychosocial determinants beyond physical activity alone.
