DESCRIPTION (provided by applicant): This project proposes to examine the association between heat exposure and traumatic injury risk in agricultural workers, assess a potential mechanism for increased injury risk in crop workers exposed to heat stress and its relation to productivity, and examine the feasibility of using a biomarker of heat acclimation to detect workers at risk for heat-related illness (HRI) and injury, with the ultimate goal of prevention. Th career development plan and research outlined in this proposal will allow Dr. Spector to build upon her background in epidemiology, biostatistics, and occupational health; combine her interests in occupational injury and HRI prevention; and develop new skills in 1) effectively using workers' compensation data to explore hypotheses; 2) testing hypotheses in working populations; and 3) translating research into practice. The local environment for public health research in Washington is outstanding, and Dr. Spector's proposed mentorship committee includes accomplished mentors with established, multidisciplinary research programs. Under the primary mentorship of Dr. Fenske, Director of the Pacific Northwest Agricultural Safety and Health (PNASH) Center, Dr. Spector will: 1) estimate the association between heat exposure and injury risk in agricultural workers using established climate models and WA workers' compensation data; 2) estimate associations between heat stress, psychomotor performance, and productivity in adult outdoor crop workers in field harvest conditions; 3) assess the feasibility of using urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) as a biomarker of heat acclimation in field conditions; 4) and address NIOSH's r2p mission through dissemination of findings to the agricultural community and industry. We expect, based on previous work, that heat stress is associated with increased injury risk and decreased psychomotor performance and productivity, particularly in poorly acclimated workers, and that increases in heat strain are associated with increases in 8-OHdG. The results, protocols, and dissemination products developed during the course of this project will be valuable outputs that we expect will improve our ability to estimate future productivity losses and health effects related to climate change, wil help us to engage employers in HRI prevention efforts, and will enable us to better measure the effectiveness of HRI prevention interventions. The ultimate goal of this work is to reduce traumatic injuries and improve the health and well-being of agricultural workers (NORA AFF Strategic Goals 4 & 5) in a changing climate. This harmonizes with Dr. Spector's ultimate career goal of preventing occupational injuries and illnesses and their consequences in at-risk occupational populations.

描述（申请人提供）：本项目拟研究农业工人热暴露与创伤性损伤风险之间的关系，评估暴露于热应激的作物工人伤害风险增加的潜在机制及其与生产力的关系，并研究使用热适应生物标志物检测工人热相关疾病（HRI）和伤害风险的可行性，最终目的是预防。本建议书中概述的职业发展计划和研究将使Spector博士能够建立在流行病学、生物统计学和职业健康的背景之上;联合收割机结合她对职业伤害和HRI预防的兴趣;并在以下方面发展新技能：1）有效利用 工人的薪酬数据，以探索假设; 2）在工作人口中检验假设; 3）将研究转化为实践。华盛顿公共卫生研究的当地环境是杰出的，斯佩克特博士提议的导师委员会包括具有既定的多学科研究项目的有成就的导师。在太平洋西北农业安全与健康中心（PNASH）主任Fenske博士的主要指导下，Spector博士将：1）使用已建立的气候模型和西澳工人的赔偿数据估计农业工人的热暴露和伤害风险之间的关联; 2）估计田间收获条件下成年户外作物工人的热应激，心理表现和生产力之间的关联; 3）评估使用尿8-羟基-2 '-脱氧鸟苷（8-OHdG）作为田间条件下热适应的生物标志物的可行性; 4）并通过向农业社区和工业界传播发现来解决NIOSH的r2 p使命。我们预计，根据以前的工作，热应激与受伤的风险增加，心理表现和生产力下降，特别是在适应不良的工人，并在热应变的增加与8-OHdG的增加。在这个项目的过程中开发的结果，协议和传播产品将是有价值的产出，我们预计将提高我们估计未来生产力损失和与气候变化相关的健康影响的能力，将有助于我们让雇主参与HRI预防工作，并使我们能够更好地衡量HRI预防干预措施的有效性。这项工作的最终目标是在不断变化的气候条件下减少创伤性伤害，改善农业工人的健康和福祉（诺拉农业基金会战略目标4和5）。这与斯佩克特博士的最终职业目标相一致，即预防职业伤害和疾病及其在高危职业人群中的后果。
