Barriers and predictors of physical fitness among volunteer firefighters

项目摘要 心血管疾病是消防员因公死亡的主要原因。消防员引发急性健康 在保护我们的社区的同时，我们还可以降低包括受伤、疲劳、热应激和心血管紧张在内的风险。 适当的身体健康是减少这些风险的重要组成部分。身体素质差，包括低 心肺健康和高体重指数，可能导致不良心血管疾病的风险增加， 呼吸系统和癌症（结肠直肠，前列腺）的结果，所有消防员的主要关注。美国 美国有110万名消防员，其中67%是志愿消防员。然而，大多数消防员健康研究都是 在职业（付费）消防员中进行。当志愿消防员训练，并执行相同的任务， 职业消防员，他们在可能导致较低的体能维护的关键方面有所不同。志愿 消防员总是随时待命，不会在消防站花费很长时间， 预计将保持培训，同时平衡其主要就业和家庭生活，减少机会， 消防部门促进健康计划。在这个建议中，我们调查了物理的预测因素和障碍， 志愿消防员的健康状况，这对于制定针对这一问题的健康促进计划至关重要。 被低估的多数人 拟议的混合方法项目将在新泽西的研究基础设施内进行 消防员癌症评估和预防研究，并将使用以前收集的调查数据， 消防和行为因素，以及关于个人和消防部门水平因素的焦点小组数据， 志愿消防员的身体素质。志愿消防员将被比作职业消防员， 国家消防员癌症队列研究建议的项目有三个具体目标：（1）确定 与消防员身体健康相关的因素，并评估志愿者和职业之间的差异 消防员;（2）定性探讨潜在的个人和消防部门的水平对身体的影响 志愿消防员之间的健身;和，（3）采用混合方法分析，通过三角定量 以及关于志愿消防员身体健康相关因素的定性数据。多变量 回归分析将用于评估行为因素和消防员服务暴露对 志愿消防员与职业消防员的身体健康状况比较。专题分析将 用于深入了解志愿者身体健康的障碍和促进因素 消防员。一个融合的混合方法分析将整合定量和定性的结果，以探讨 健康行为和志愿者消防特征如何以及为什么影响身体健康。通过 调查志愿消防员身体素质的预测因素和障碍， 和健康促进战略。

PROJECT SUMMARY Cardiovascular disease is the leading cause of on-duty deaths among firefighters. Firefighters incur acute health risks including injury, fatigue, heat stress, and cardiovascular strain while protecting our communities. Appropriate physical fitness is an essential part of reducing these risks. Poor physical fitness, including low cardiorespiratory fitness and high body mass index, can contribute to increased risks of adverse cardiovascular, respiratory, and cancer (colorectal, prostate) outcomes, all major concerns among firefighters. The United States has 1.1 million firefighters, 67% of whom are volunteer firefighters. However, most firefighter heath research is conducted among career (paid) firefighters. While volunteer firefighters train for, and perform the same tasks as career firefighters, they differ in key ways that may lead to lower physical fitness maintenance. Volunteer firefighters are always on call for emergency responses, do not spend extended time in the fire station, and are expected to maintain training while balancing their primary employment and family life, reducing opportunity for fire-department promoted health programs. In this proposal, we investigate the predictors and barriers of physical fitness among volunteer firefighters, which are critical for developing health promotion programs targeted at this understudied majority. The proposed mixed-methods project will be conducted within the research infrastructure of the New Jersey Firefighter Cancer Assessment and Prevention Study, and will use previously collected survey data on firefighting and behavioral factors, and focus group data on individual- and fire-department level factors affecting physical fitness among volunteer firefighters. Volunteer firefighters will be compared to career firefighters from the national Fire Fighter Cancer Cohort Study. The proposed project has three specific aims: (1) To identify factors associated with physical fitness among firefighters and assess differences among volunteer and career firefighters; (2) To qualitatively explore potential individual- and fire-department level influences on physical fitness among volunteer firefighters; and, (3) To employ a mixed-methods analysis by triangulating quantitative and qualitative data regarding factors associated with physical fitness among volunteer firefighters. Multivariable regression analysis will be used to assess effects of behavioral factors and firefighter service exposures on physical fitness among volunteer firefighters compared with those for career firefighters. Thematic analysis will be used to generate an in-depth understanding of the barriers and promoters of physical fitness among volunteer firefighters. A convergent mixed-methods analysis will integrate quantitative and qualitative findings to explore how and why health behaviors and volunteer firefighting characteristics influence physical fitness. By investigating the predictors and barriers of physical fitness among volunteer firefighters, specific physical fitness and health promotion strategies can be informed.
