Objective In 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. Methods The 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. Results The 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. Conclusions The “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.

IntroductionInsomnia during pregnancy presents significant medical care challenges and heightens the risk of adverse outcomes for both pregnant women and fetuses. This study undertook a meta-analysis to assess the global prevalence of insomnia during pregnancy, examining both the overall prevalence and regional variations.MethodThe aim of this study was to perform a meta-analysis of articles indexed in PubMed, Embase, and Web of Science from the inception of these databases up to February 29, 2024. The study systematically reviewed the global prevalence of gestational insomnia and explored potential moderating factors, encompassing research type, publication date, regional influences, maternal age, pregnancy status, depressive symptoms, and anxiety symptoms.ResultForty-four studies, encompassing a total of 47,399,513 participants, were included in the analysis. The overall prevalence of insomnia symptoms during pregnancy was 43.9%. Regional factors and depression emerged as the main factors affecting insomnia, with Europe (53.6%) surpassing North America (41.0%), followed by South America (50.6%) and Asia (40.7%). High depression rates (56.2%) correlated with increased insomnia prevalence compared to low depression rates (39.8%). The type of research and publication date showed no significant impact on the prevalence of insomnia symptoms.ConclusionThe meta-analysis results indicated that the prevalence of insomnia symptoms was higher during pregnancy, especially among pregnant women who were in a highly depressed state or located in the European region.Systematic review registrationPROSPERO, identifier CRD42018104460.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
