农作物工人因繁重的体力劳动产生的内热而患热相关疾病（HRI）的风险很高，特别是在炎热和潮湿的条件下工作时。本研究的目的是确定HRI症状的危险因素，在华盛顿作物工人使用音频计算机辅助自我访谈（A-CASI）的工具，经过了可靠性和有效性评估。2013年夏季，对华盛顿州的97名作物工人进行了横断面A-CASI调查。在人口统计学，培训，工作，水合作用，服装，健康和环境领域的潜在HRI风险因素被事先选择进行评估。使用混合效应逻辑回归来识别与热应激相关的自我报告症状和在炎热条件下工作时经历的HRI（头晕/头晕或出汗过多）的风险因素。年龄的增加与HRI症状的几率较低相关（比值比[OR] 0.92; 95%置信区间[CI] 0.87-0.98）。计件工资与小时工资相比（OR 6.20; 95%CI 1.11-34.54），需要步行3分钟以上才能到达厕所，而不到3分钟（OR 4.86; 95%CI 1.18-20.06），与HRI症状的几率较高相关。在这项对华盛顿农作物工人HRI症状危险因素的描述性研究中，年龄降低（和工作经验减少）、计件工资和距离厕所较远与自我报告的HRI症状相关。在使用具有代表性的工作人群的客观措施进行评估的HRI预防工作中，应考虑可改变的工作场所因素。
Crop workers are at high risk of heat-related illness (HRI) from internal heat generated by heavy physical work, particularly when laboring in hot and humid conditions. The aim of this study was to identify risk factors for HRI symptoms in Washington crop workers using an audio computer-assisted self-interview (A-CASI) instrument that has undergone reliability and validity evaluation. A cross-sectional A-CASI survey of 97 crop workers in Washington State was conducted during the summer of 2013. Potential HRI risk factors in demographic, training, work, hydration, clothing, health, and environmental domains were selected a priori for evaluation. Mixed effects logistic regression was used to identify risk factors for self-reported symptoms associated with heat strain and HRI (dizziness/light-headedness or heavy sweating) experienced at work in hot conditions. An increase in age was associated with a lower odds of HRI symptoms (odds ratio [OR] 0.92; 95% confidence interval [CI] 0.87–0.98). Piece rate compared to hourly payment (OR 6.20; 95% CI 1.11–34.54) and needing to walk for more than three minutes to get to the toilet, compared to less than three minutes (OR 4.86; 95%CI 1.18–20.06), were associated with a higher odds of HRI symptoms. In this descriptive study of risk factors for HRI symptoms in Washington crop workers, decreased age (and less work experience), piece rate pay, and longer distance to the toilet were associated with self-reported HRI symptoms. Modifiable workplace factors should be considered in HRI prevention efforts that are evaluated using objective measures in representative working populations.
