Electronic device usage pattern is associated with sleep disturbances in adolescents: a latent class analysis.

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
This study aimed to identify individual differences in adolescents' electronic device usage patterns and explore their unique associations with sleep disturbances. From May to June 2019, students from 18 middle schools in Fuzhou were invited to fill out questionnaires about sleep health and electronic device usage, including screen time, usage timing, usage purpose, pre-sleep usage, and the presence of devices in bedrooms. Latent class analysis was employed to identify distinct usage patterns, and their associations with sleep disturbances were subsequently explored. Four usage patterns were identified among a total of 19,229 adolescents: (1) "minor exposure-learning," (2) "weekends dominance-game playing," (3) "weekends and pre-sleep dominance-learning," and (4) "excessive exposure-game playing." Compared to Pattern 1, a higher likelihood of insufficient sleep was found during weekdays and weekends in Pattern 3 (weekdays-odds ratio (OR) 1.15, 95% confidential interval (CI) 1.0-1.28; weekends-OR 1.19, 95% CI 1.09-1.30) and Pattern 4 (weekdays-OR = 1.48, 95% CI 1.31-1.68; weekends-OR = 1.40, 95% CI 1.27-1.53) but only during weekends in Pattern 2 (OR = 1.18, 95% CI 1.07-1.30). Besides, Patterns 2-4 were related to delayed bedtime, insomnia symptoms, and recurrent sleep paralysis or nightmares.
conclusionFour electronic device usage patterns were found among adolescents. Compared with the pattern of minimal screen exposure and a learning purpose, other patterns were more likely to be associated with sleep disturbances. These findings carry significant implications for healthy electronic device usage and potential strategies to improve adolescents' sleep health. WHAT IS KNOWN: • As screen use among adolescents increases, promoting healthy digital habits is crucial for reducing sleep disruptions and enhancing well - being. • Existing recommendations on adolescents' electronic device use mainly focus on usage duration and lack systematic advice. WHAT IS NEW: • Latent class analysis (LCA) identified four electronic device usage patterns among Chinese adolescents, based on screen time, usage timing, purpose, pre-sleep usage, and device presence in bedrooms. • Reducing usage, especially pre-bedtime, using devices for education, and keeping them out of the bedroom were less linked to sleep issues.
