Abstract

Background: The high prevalence of poor sleep quality (PSQ) in the general population leads to negative health outcomes. Since estimates of PSQ prevalence in the Chinese general population vary widely, this meta-analysis aimed to refine these estimates and to identify moderating factors.

Methods: A comprehensive literature search was undertaken in both international (PubMed, PsycINFO, Web of Science, and EMBASE) and Chinese (Wanfang, and the China National Knowledge Infrastructure databases) databases from inception to 23 November 2023. Studies were required to have used standard scales such as the Chinese version of the Pittsburgh Sleep Quality Index (PSQI). The pooled prevalence of PSQ and 95% confidence intervals (CIs) were calculated using a random-effects model. Subgroup and meta-regression analyses were performed to identify sources of heterogeneity.

Results: In 32 studies with a combined 376,824 participants, the pooled prevalence of PSQ was 19.0% (95% CI 15.8-22.8%; range 6.6-43.6%). Across 22 studies that reported PSQI data, the pooled mean score was 4.32 (95%CI 3.82-4.81; SD = 0.502). The pooled mean sleep duration across 8 studies was 7.62 (95% CI 7.23-8.00; SD = 0.194) hours. Subgroup analyses showed that lower education (Q = 4.12, P = 0.042), living in less developed regions (Q = 60.28, P < 0.001), and lower PSQI cutoff values (Q = 9.80, P = 0.007) were significantly associated with PSQ. Meta-regression analyses showed that study quality was inversely associated with estimated PSQ prevalence (β = - 0.442, P = 0.004).

Limitations: Although measures such as subgroup and meta-regression analyses were performed, substantial heterogeneity remained. Information related to sleep quality, such as comorbid physical diseases or psychiatric disorders, substance use, occupational types, and employment status, were not reported in most studies.

Conclusion: One in five people in the general population of China may have PSQ and people with lower education or living in western regions may be more susceptible.

中国普通人群睡眠质量差的患病率：流行病学研究的荟萃分析。

背景：睡眠质量差（PSQ）在普通人群中的高流行率导致了不良的健康后果。由于对中国普通人群中不良睡眠质量发生率的估计差异很大，本荟萃分析旨在完善这些估计值并确定调节因素：方法：我们在国际（PubMed、PsycINFO、Web of Science 和 EMBASE）和国内（万方数据库和中国国家知识基础设施数据库）数据库中进行了全面的文献检索，检索时间从开始到 2023 年 11 月 23 日。研究必须使用标准量表，如中文版匹兹堡睡眠质量指数（PSQI）。采用随机效应模型计算PSQ的汇总患病率和95%置信区间（CI）。为了确定异质性的来源，还进行了分组和元回归分析：在 32 项共 376824 名参与者的研究中，汇总的 PSQ 患病率为 19.0%（95% CI 15.8-22.8%；范围 6.6-43.6%）。在 22 项报告 PSQI 数据的研究中，汇总的平均得分为 4.32 (95%CI 3.82-4.81; SD = 0.502)。8 项研究的汇总平均睡眠时间为 7.62 (95%CI 7.23-8.00; SD = 0.194) 小时。亚组分析表明，教育程度较低（Q = 4.12，P = 0.042）、生活在欠发达地区（Q = 60.28，P 限制：虽然进行了分组分析和元回归分析等措施，但仍存在很大的异质性。大多数研究没有报告与睡眠质量有关的信息，如合并躯体疾病或精神疾病、药物使用、职业类型和就业状况等：结论：在中国的普通人群中，每五个人中就有一人可能患有 PSQ，而教育程度较低或生活在西部地区的人群可能更易患 PSQ。

期刊介绍： The original papers published in the European Archives of Psychiatry and Clinical Neuroscience deal with all aspects of psychiatry and related clinical neuroscience. Clinical psychiatry, psychopathology, epidemiology as well as brain imaging, neuropathological, neurophysiological, neurochemical and moleculargenetic studies of psychiatric disorders are among the topics covered. Thus both the clinician and the neuroscientist are provided with a handy source of information on important scientific developments.
