The relationship between social media use and health risk behaviors among college students: a network analysis.
Article in BMC psychology, 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
backgroundHealth risk behaviors are crucial to developing college students’ mental and physical health. This study aimed to explore the relationship between social media use and health risk behaviors and to examine the structural relationships between the two through network analysis.
methodsThis study was a cross-sectional design with a convenience sample of 3,489 college students aged 18–22 years, and data were collected using relevant questionnaires. R 4.3.2 software was used to construct the social media use and health risk behaviors network to explore the complex relationship between the variables.
resultsIn the social media use and health risk behaviors network, there are 25 edges connecting two communities. Physiological damage, psychological addiction behaviors, and risky sexual behaviors have the greatest expected impact, with Bridge Expected Influence (BEI) values of 0.15, -0.27, and 0.22, respectively. The Directed Acyclic Graph (DAG) indicates that physiological damage occupies an upstream position (i.e., appearing earlier in the causal pathway) among all influencing factors.
conclusionPhysical damage and psychological addiction behaviors are key bridging nodes in the network, playing a central role in increasing participation in inter-symptom interactions. The DAG shows that physical damage is at the top of the network and can influence health risk behaviors through fear of missing out and cognitive failure. The bridge-centered indicators identified in this study can be used as a guide to action for the intervention of college students’ health risk behaviors, to effectively prevent and mitigate the occurrence of college students’ health risk behaviors.
