Changes in insomnia symptoms among compulsory education students in China after the "Double Reduction" policy: a two-wave longitudinal study.
Article in BMC psychiatry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveIn July 2021, the "Double Reduction" policy was introduced in China, aiming to alleviate the burden of excessive homework and off-campus tutoring for students in the compulsory education stage. The purpose of this study is to explore the changes in students' insomnia symptoms and related factors after the policy implementation. Meanwhile, sex differences were further examined.
methodsThe baseline survey (T1) began in April 2021 (pre-policy), with a follow-up (T2) conducted in December 2021 (post-policy). A total of 28,398 students completed both T1 and T2 surveys and were included in this study. Insomnia symptoms were measured at both T1 and T2 using three questions from the Youth Self-Report Insomnia Scale. Demographics and anxiety and depressive symptoms were collected at T1, and policy-related indicators were assessed at T2.
resultsThe prevalence of insomnia symptoms showed a slight decrease after the "Double Reduction" policy (9.9% vs. 9.2%). After controlling for demographics and anxiety and depressive symptoms, reduced homework (OR: 0.75 [0.65-0.86]), more family time (OR: 0.50 [0.44-0.57]), and reduced academic pressure (OR: 0.77 [0.71-0.83]) post-policy were related to a lower risk of new-onset insomnia symptoms. Additionally, more family time (OR: 0.59 [0.49-0.72]) and reduced academic pressure (OR:0.70 [0.56-0.86]) were factors against persistent insomnia symptoms. There were no significant sex differences in the associations between policy-related indicators and insomnia symptoms.
conclusionsThe "Double Reduction" policy has somewhat improved the students' insomnia symptoms. Extending family time, and alleviating homework and academic burden are considered measures for maintaining sleep health in students.
