Agricultural workers in the United States (U.S.) are exposed to occupational heat stress, increasing their risk of adverse kidney outcomes. The aim of this integrative review was to explore the relationship between occupational heat stress and kidney health among U.S. agricultural workers. PubMed, EMBASE, Scopus, and Google Scholar were searched for original research articles on this relationship among U.S. agricultural workers. Studies were screened and reviewed by two independent reviewers in three phases: title and abstract screening, full text screening, and data extraction. The search yielded 278 articles; 14 were included in the final analysis. Heat stress was commonly measured using core body temperature changes, heat index, and wet-bulb globe temperature. Acute kidney injury (AKI) incidence following a single work shift was up to 43%. Occupational heat stress and piece-rate compensation increased the odds for developing AKI. The use of cooling bandanas and water mixed with electrolytes are promising interventions for mitigating the effect of heat stress on kidney health outcomes. The results confirm that occupational heat stress influences kidney health for U.S. agricultural workers. The mechanisms of this relationship have not been fully elucidated. More studies exploring heat protection interventions are needed.
美国的农业工人面临职业性热应激，这增加了他们出现不良肾脏后果的风险。本综合综述的目的是探讨美国农业工人职业性热应激与肾脏健康之间的关系。我们在PubMed、EMBASE、Scopus和谷歌学术上搜索了关于美国农业工人中这种关系的原始研究文章。研究由两名独立评审员分三个阶段进行筛选和评审：标题和摘要筛选、全文筛选以及数据提取。搜索共得到278篇文章；最终分析纳入了14篇。热应激通常通过核心体温变化、热指数和湿球黑球温度来测量。单次轮班后的急性肾损伤（AKI）发病率高达43%。职业性热应激和计件薪酬增加了患AKI的几率。使用冷却头巾以及含有电解质的混合水是减轻热应激对肾脏健康结果影响的有前景的干预措施。结果证实职业性热应激会影响美国农业工人的肾脏健康。这种关系的机制尚未完全阐明。需要更多探索热防护干预措施的研究。
