How perceived stress and social support shape non-communicable disease risks beyond traditional factors: a machine learning perspective.
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
backgroundPsychosocial factors such as perceived stress and social support have been increasingly recognized as significant contributors to non-communicable diseases (NCDs). However, their predictive value in comparison to traditional risk factors remains insufficiently explored. This study used machine learning-based random forest models to compare the relative importance of psychosocial factors and traditional risk factors in predicting NCD risk.
methodsCross-sectional data were collected from March to June 2021 from a sample of 2567 participants aged 40 years or older in Ningbo City, China. Random forest models were constructed to predict the occurrence of NCDs, including hypertension, diabetes, hyperlipidemia, and chronic respiratory diseases. Model performance was evaluated using accuracy, sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). The importance of features was assessed using both mean decrease in Gini and permutation importance metrics.
resultsThe results demonstrated that random forest models exhibited satisfactory performance in predicting various types of NCDs, achieving accuracies ranging from 0.662 to 0.805 and AUC values from 0.642 to 0.728. Moreover, subjective social support and perceived stress consistently ranked as the fourth, fifth, or sixth most influential factors after age, BMI, and waist circumference but ahead of smoking and salt intake.
conclusionsThe findings unveiled the pivotal roles of psychosocial factors, such as perceived stress and subjective social support, in the prevention and management of NCDs. Notably, these psychosocial factors frequently ranked among the top predictors, demonstrating predictive importance comparable to that of established traditional risk factors. It is recommended that prevention and management guidelines for NCDs incorporate solid components targeting these psychosocial factors.
