Poor sleep is associated with bad health outcomes, worse wellbeing and decreases in performance, productivity and safety at work. Police officers are exposed to several risk factors including extended work schedules, shift work, occupational stress, dangerous and traumatic events and can, as such, develop sleep problems. The aim of the present study was to analyze the sleep quality among police officers. A systematic literature search, in PubMed/MEDLINE, PsycINFO, Scopus, ISI/Web of Science (WoS) and the Cochrane Library was conducted. Original articles, published in English, French, Italian, Spanish and Portuguese, the primary objective of which was the evaluation of the quality of sleep through the Pittsburgh Sleep Quality Index (PSQI) in Police Forces, were selected. From an initial sample of 1,149 studies, 13 articles were included in the meta-analysis (3,722 police officers). The pooled prevalence of bad sleep quality in police officers was 51% [95%CI 42⁻60%]. The pooled global score of the PSQI was 5.6 [95%CI 5.0⁻6.3], corresponding to a low average quality. At the meta-regressions, statistically significant associations could be found for work seniority (in terms of years of service) and being on shift. The poor quality of sleep in police officers could have negative consequences for workers' health and for the safety of third parts. The implementation of health and sleep hygiene promotion programs in police forces is strongly recommended.
睡眠质量差与健康状况不佳、幸福感下降以及工作绩效、生产力和安全性下降有关。警察面临着多种风险因素，包括延长工作时间、轮班工作、职业压力、危险和创伤性事件，因此可能会出现睡眠问题。本研究旨在分析警察的睡眠质量。在 PubMed/MEDLINE、PsycINFO、Scopus、ISI/Web of Science (WoS) 和 Cochrane 图书馆进行了系统的文献检索。选择了以评估睡眠质量为主要目的的英文、法文、意大利文、西班牙文和葡萄牙文的原始文章，使用匹兹堡睡眠质量指数 (PSQI) 对警察部队进行评估。从最初的 1149 项研究中，有 13 项研究被纳入荟萃分析（3722 名警察）。警察中睡眠质量差的总患病率为 51%[95%CI 42⁻60%]。PSQI 的总体得分是 5.6[95%CI 5.0⁻6.3]，表明平均睡眠质量较低。在荟萃回归分析中，可以发现工作年限（以服务年限计）和轮班工作与睡眠质量之间存在统计学上的显著关联。警察睡眠质量差可能对工人的健康和第三方的安全产生负面影响。强烈建议在警察部队中实施健康和睡眠卫生促进计划。
