Abstract

The purpose of this study was to assess the effect of wildland firefighting on measures of cardiovascular health. The study was carried out in two parts. Part one assessed relationships between years of wildland firefighting and cardiovascular variables (n = 28). Part two looked at cardiovascular variables pre and post a wildland firefighting season (n = 18). Independent of age, a statistically significant relationship between number of seasons firefighting and VO_2max was found (r²=.140, p=.048). A statistically significant reduction in VO_2max of -4.1 ± 5.7 ml·kg^-1 min^-1 was witnessed following fire season (95%CI=-6.9 to -1.3, p=.048). Year to date hazard pay was significantly correlated with ankle-brachial index (r=-.474, p=.040). Wildland firefighters who reported >640 h of hazard pay had a greater VO_2max reduction than those reporting less hazard pay (-1.7 ± 5.7 ml·kg^-1·min^-1 vs. -7.1 ± 4.3 ml·kg^-1·min^-1, p=.037). Wildland firefighting may negatively impact cardiorespiratory fitness and arterial health.

野外消防对动脉僵硬度和心肺健康的影响。

本研究的目的是评估野外消防对心血管健康指标的影响。研究分两部分进行。第一部分评估了野外消防年数与心血管变量之间的关系(n = 28)。第二部分研究了野外消防季节前后的心血管变量(n = 18)。与年龄无关，消防季节数与VO2max之间的关系具有统计学意义(r2=)。140年,p = .048)。火灾季节后，VO2max降低了-4.1±5.7 ml·kg-1 min-1，具有统计学意义(95%CI=-6.9 ~ -1.3, p= 0.048)。迄今为止，危险报酬与踝肱指数显著相关(r=-)。474年,p = .040)。报告超过640小时危险报酬的消防员比报告较少危险报酬的消防员的VO2max降低更大(-1.7±5.7 ml·kg-1·min-1 vs -7.1±4.3 ml·kg-1·min-1, p= 0.037)。野外消防可能对心肺健康和动脉健康产生负面影响。

期刊介绍： Archives of Environmental & Occupational Health , originally founded in 1919 as the Journal of Industrial Hygiene, and perhaps most well-known as the Archives of Environmental Health, reports, integrates, and consolidates the latest research, both nationally and internationally, from fields germane to environmental health, including epidemiology, toxicology, exposure assessment, modeling and biostatistics, risk science and biochemistry. Publishing new research based on the most rigorous methods and discussion to put this work in perspective for public health, public policy, and sustainability, the Archives addresses such topics of current concern as health significance of chemical exposure, toxic waste, new and old energy technologies, industrial processes, and the environmental causation of disease such as neurotoxicity, birth defects, cancer, and chronic degenerative diseases. For more than 90 years, this noted journal has provided objective documentation of the effects of environmental agents on human and, in some cases, animal populations and information of practical importance on which decisions are based.
