Sleep quality is directly correlated with overall health and quality of life. Firefighters have a higher workload and injury rate than those in other occupations. This study investigated the prevalence of and risk factors for poor sleep quality among firefighters in Taiwan. This cross-sectional study was conducted between November 2019 and August 2020. Sociodemographic information of the study participants was collected using a structured self-administered questionnaire. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the subjective sleep quantity and quality of firefighters during the previous month. A t test for continuous variables and χ2 test for categorical variables were performed for univariate analysis. Logistic regression analysis was conducted for multivariate analysis. Eight hundred eighty-nine firefighters completed the questionnaire during the study period, with a response rate of 88.9%. Among them, 447 (50.3%) reported poor sleep quality. Logistic regression analysis showed that female sex, longer work duration (>5 years) for firefighters, on-call shift work, and no leisure-time physical activity (LTPA) was significantly correlated with an increased risk of poor sleep quality. Advanced analysis of partaking in LTPA revealed that high-intensity LTPA is significantly associated with higher rates of poor sleep quality. In contrast, adequate rest after LTPA correlated with lower rates of poor sleep quality. Firefighters are at higher risk of poor sleep quality. Emphasis should be placed on firefighters' regular LTPA, particularly when experiencing sleep problems.
睡眠质量与整体健康和生活质量直接相关。消防员的工作量和受伤率比其他职业高。本研究调查了台湾消防员睡眠质量差的患病率和危险因素。这是一项横断面研究，于 2019 年 11 月至 2020 年 8 月进行。使用结构化的自我管理问卷收集研究参与者的社会人口统计学信息。使用匹兹堡睡眠质量指数（PSQI）中文版评估消防员在前一个月的主观睡眠量和质量。对连续变量进行 t 检验，对分类变量进行卡方检验进行单变量分析。对多变量分析进行逻辑回归分析。在研究期间，889 名消防员完成了问卷，应答率为 88.9%。其中，447 名（50.3%）报告睡眠质量差。逻辑回归分析表明，女性、消防员工作时间较长（>5 年）、轮班工作和没有闲暇时间体力活动（LTPA）与睡眠质量差的风险增加显著相关。对参与 LTPA 的进一步分析表明，高强度 LTPA 与睡眠质量差的发生率显著相关。相比之下，LTPA 后充分休息与睡眠质量差的发生率较低相关。消防员睡眠质量差的风险较高。应重视消防员的定期 LTPA，尤其是在出现睡眠问题时。
