Abstract：
BACKGROUND: Due to the nature of their job, firefighters face many ergonomic risk factors and are exposed to several musculoskeletal disorders (MSDs). The aim of this systematic review and meta-analysis was to investigate the prevalence of MSDs among firefighters.
METHODS: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The literature search was conducted in the databases of PubMed, Scopus, Web of Science, Science Direct, SID, ISC and Google Scholar without applying a time limitation until the end of July 2022. The random effects model was used for meta-analysis, and the I2 index was used to check heterogeneity among studies. The data were analyzed using STATA version 14 software.
RESULTS: The primary literature searches in the databases identified 1,291 articles, 26 of which were entered the meta-analysis stage after screening, study selection, and quality assessment, including 36,342 firefighters. Based on the results of a meta-analysis, the overall prevalence of MSDs among firefighters was 46.39% (95% CI: 32.45-60.32, I2 = 99.7%, P < 0.001). The prevalence of MSDs was also investigated at neck (18.36%), low back (34.32%), shoulder (18.68%), hands (7.43%), upper back (10.15%), knee (19.97%) and foot (6.66%).
CONCLUSIONS: Considering the relatively high prevalence of MSDs among firefighters and their higher exposition to specific job-related risk factors of MSDs compared to other professions, it is suggested to provide firefighters with appropriate training, implement ergonomic interventions, and regularly screen them to reduce MSDs.

摘要：
背景：由于他们的工作性质，消防员面临许多人体工程学危险因素，并暴露于多种肌肉骨骼疾病（MSD）。本系统评价和荟萃分析的目的是调查消防员中MSD的患病率。
方法：本研究基于系统评价和荟萃分析（PRISMA）指南的首选报告项目进行。文献检索在PubMed的数据库中进行，Scopus,WebofScience,科学直接，SID,ISC和GoogleScholar在2022年7月底之前没有时间限制。随机效应模型用于荟萃分析，I2指数用于检查研究之间的异质性。使用STATA版本14软件分析数据。
结果：在数据库中进行的主要文献搜索确定了1,291篇文章，其中26例在筛选后进入荟萃分析阶段，研究选择，和质量评估，包括36342名消防员.根据荟萃分析的结果，消防员中MSD的总体患病率为46.39%(95%CI:32.45-60.32,I2=99.7%,P<0.001)。颈部也调查了MSD的患病率(18.36%)，低背部（34.32%），肩部（18.68%），手(7.43%)，上背部(10.15%),膝盖（19.97%）和脚（6.66%）。
结论：考虑到消防员中MSD的患病率相对较高，并且与其他职业相比，他们对MSD的特定工作相关风险因素的披露更高，建议为消防员提供适当的培训，实施人体工程学干预措施，并定期筛选它们以减少MSD。
