OBJECTIVE
Recent findings suggest that laboring in hot occupational environments is related to kidney damage in agricultural workers. We examined hydration status and kidney function in 192 Florida agricultural workers.
METHODS
Blood and urine samples were collected over 555 workdays during the summers of 2015 and 2016. Urine-specific gravity (USG), serum creatinine, and other kidney function markers were examined pre- and post-shift on each workday. Multivariable mixed modeling was used to examine the association of risk factors with hydration status and acute kidney injury (AKI).
RESULTS
Approximately 53% of workers were dehydrated (USG ≥1.020) pre-shift and 81% post-shift; 33% of participants had AKI on at least one workday. The odds of AKI increased 47% for each 5-degree (°F) increase in heat index.
CONCLUSION
A strikingly high prevalence of dehydration and AKI exists in Florida agricultural workers.
目的
最近的研究结果表明，在炎热的职业环境中劳作与农业工人的肾脏损伤有关。我们研究了 192 名佛罗里达农业工人的水合状态和肾功能。
方法
在 2015 年和 2016 年的夏季，采集了超过 555 个工作日的血液和尿液样本。在每个工作日的班前和班后，检测尿比重（USG）、血清肌酐和其他肾功能标志物。采用多变量混合模型来研究危险因素与水合状态和急性肾损伤（AKI）之间的关联。
结果
大约 53%的工人在班前和班后均出现脱水（USG≥1.020）；81%的工人至少有一天出现 AKI。热指数每升高 5 度（°F），AKI 的发生几率增加 47%。
结论
佛罗里达农业工人中存在脱水和 AKI 的高患病率。
