Evaluating short-term air pollution-related mental health resilience using a directional network.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRecent studies have shown that air pollution is among the most important triggers of mental health risks. However, little is known about the resilience strategies that reduce mental health risks among individuals exposed to pollution. The interconnections of protective and risk factors further complicate the understanding of mental health resilience. Therefore, this study developed a resilience assessment framework accounting for factor interconnections to evaluate the short-term air pollution-related mental health resilience.
methodsAligned with mental health resilience theory, a Bayesian network model and network analysis were applied to construct a quantitative network of factor interconnections, analyzing 2019-2020 data for 24,261 older adults from the Shandong Aging and Mental Health Survey. On the basis of the network, mental health resilience was assessed via multiple-criteria decision-making method. The most influential pollutants, vulnerable populations and strategies to increase mental health resilience were then proposed.
resultsAir pollution exposure directly and indirectly affected mental health outcomes, defining a directional network where fine particulate matter emerged as the most influential pollutant. The mean index for short-term air pollution-associated mental health resilience was 0.52 ± 0.18. Resilience was significantly lower among females, adults aged 65-75, and less-educated individuals (mean index: 0.518 (95% CI: 0.515-0.521), 0.517 (95% CI: 0.515-0.520), and 0.516 (95% CI: 0.513-0.519), respectively). Memory lapses for sex/education disparities, irritability and feeling afraid for age disparities demonstrated the steepest disparities across demographic subgroups and bridge nodes-critical junctures that mediate resilience dynamics between populations. In terms of conditional probability, adjusting resilience factors proved more effective than merely reducing exposure.
conclusionsThis study has illuminated a directional network linking air pollution to mental health, with a specific focus on fine particulate matter. Thus, enhancing mental health resilience against air pollution requires a coordinated yet targeted approach, prioritizing interventions for fine particular matter exposure. Furthermore, policymakers should address resilience disparities by tailoring interventions to mitigate memory lapses (which exhibit sex/education gaps) and irritability and feeling afraid (associated with age-related vulnerabilities).
