Associated factors of anxiety and depressive symptoms among coal miners in Shanxi, China: a cross-sectional study.
Article in BMC public health, 2025. 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 AND
objectivesCoal miners are exposed to a significant risk of anxiety and depression due to challenging work environment. However, there is a lack of studies comprehensively examining the associated factors of anxiety and depressive symptoms among coal miners. Our study aimed to identify these associated factors among Chinese coal miners in Shanxi Province.
methodsIn August and September 2022, a cross-sectional study was conducted using a cluster sampling method to enroll all workers from the L coal mines in Linfen City, China. Data were collected using a self-designed and administered online questionnaire, which included the Generalized Anxiety Disorder-7 (GAD-7) and the Center for Epidemiologic Studies Depression Scale 10-item (CESD-10) to assess anxiety and depressive symptoms, along with questions on sociodemographics, work-related factors, health status, and lifestyle factors. Logistic regression was used to identify associated factors for anxiety and depressive symptoms. Sensitivity analysis was conducted using linear regression.
resultsA total of 1,027 participants were included in the analysis. Among them, 278 (27.07%) exhibited anxiety symptoms, and 238 (23.17%) showed depressive symptoms. In the multivariable logistic regression, associated factors identified for both anxiety and depressive symptoms included having direct or indirect safety accident experience (adjusted odds ratio [aOR] for anxiety: 1.76, 95% confidence interval [CI]: 1.29 ~ 2.40; aOR for depression: 1.72, 95% CI: 1.25 ~ 2.38), presence of occupational diseases (aOR for anxiety: 4.00, 95% CI: 1.51 ~ 11.10; aOR for depression: 3.36, 95% CI: 1.25 ~ 9.23), self-reported non-optimal health status (aOR for anxiety: 1.68, 95% CI: 1.19 ~ 2.37; aOR for depression: 2.01, 95% CI: 1.41 ~ 2.85), current alcohol consumption (aOR for anxiety: 1.83, 95% CI: 1.27 ~ 2.66; aOR for depression: 1.64, 95% CI: 1.12 ~ 2.41), and sleep duration of less than 7 hours (aOR for anxiety: 1.84, 1.36 ~ 2.50; aOR for depression: 1.71, 95% CI: 1.25 ~ 2.36). In addition, working in a management position (aOR: 1.99, 95% CI: 1.02 ~ 3.96) was positively associated with anxiety symptoms.
conclusionsOur study identified key factors associated with anxiety and depressive symptoms among Chinese coal miners. Management was more likely to experience anxiety symptoms. These findings underscore the need for targeted mental health interventions within the coal mining industry to improve their well-being.
