Identification of biological rhythm disorder profiles and associated problematic digital behaviors among university students: a latent profile 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
objectiveThis study aimed to identify latent profiles of Biological Rhythm Disorders (BRDs) among university students and to examine their associations with Problematic Digital Behaviors (PDBs).
methodsA total of 2,660 students from four universities in Hunan Province were surveyed. Biological rhythm disturbances were assessed using the Questionnaire of BRDs for Adolescents, while PDBs were evaluated using the Problematic Short-Form Video Media Use Scale, Problematic Social Network Use Tendency Scale, and Internet Game Addiction Scale. Latent profile analysis (LPA) was conducted with Mplus 8.3 to classify participants into distinct biological rhythm profiles. One-way ANOVA and multinomial logistic regression in SPSS 27.0 were used to examine demographic and behavioral predictors of profile membership.
resultsLPA identified four profiles of BRDs: Stable Rhythm (n = 774, 29.1%), Mild Disturbance (n = 956, 35.9%), Overall Disturbance (n = 500, 18.8%), and Sleep-Activity Disturbance (n = 430, 16.2%). Multinomial logistic regression showed that higher levels of Internet Gaming Addiction were associated with a greater likelihood of belonging to the Overall Disturbance profile (OR = 1.09, 95% CI: 1.07–1.12), whereas Problematic Short-Form Video Use (OR = 1.10, 95% CI: 1.08–1.12) and Problematic Social Network Use (OR = 1.08, 95% CI: 1.05–1.11) was notably associated with the Sleep-Activity Disturbance profile.
conclusionsBRDs among university students exhibit notable heterogeneity. The influence of PDBs differs across rhythm disturbance profiles. Interventions promoting biological rhythm health should consider students’ sex, academic year, and digital behavior patterns to develop personalized preventive strategies.
