The Influence of Substance Use on Sleep Duration Among South Korean Adolescents by Sex: A Secondary Analysis.
Article in Journal for specialists in pediatric nursing : JSPN, 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
purposeAlthough insufficient sleep influences cognitive function and physical and mental health in adolescents, many still get less sleep than the recommended duration. Adolescent substance use, including alcohol and tobacco, influences sleep disturbance. However, sex differences in the relationship between substance use and sleep health have not been extensively studied. This study aimed to examine the effect of substance use on sleep duration among South Korean adolescents by sex. DESIGN AND
methodsThis secondary data analysis used the 4th Wave of the Korean Children and Youth Panel Survey 2018 and applied a multiple regression analysis. Tobacco use and alcohol consumption were assessed by asking whether the participants had ever smoked or drunk alcohol during the previous year. Sleep duration was calculated based on the participants' reports related to sleep and awake times on weekdays and weekends.
resultsFor male adolescents, substance use, either tobacco use or alcohol consumption, did not significantly affect sleep duration, whereas for female adolescents, alcohol consumption was found to influence sleep duration. Age and subjective health were additional influential factors for adolescents' sleep duration, regardless of sex. PRACTICE IMPLICATIONS: Interventions for alcohol consumption should be considered to enhance sleep health in female South Korean adolescents. Further studies are needed to understand the underlying mechanisms of sleep health, particularly the effects of substance use, among male adolescents.
