This longitudinal study evaluated renal function and acute kidney injury (AKI) over time in US agricultural workers.
We followed Florida agricultural workers from January 2020 to August 2022, collecting blood and urine preworkday and postworkday during five visits.
Preworkday estimated glomerular filtration rate function in all participants was lower in summers but relatively consistent over time. In participants who worked almost exclusively in fernery operations (piece-rate compensation), we observed a high incidence of postworkday AKI in 2020 (21%) that increased to 43% by the end of the study. In comparison, 11% of nursery workers (hourly compensation) had AKI, and this rate was fairly stable.
AKI risk over time differs according to the type of agricultural work. Piece rate workers who are incentivized to forgo rest breaks and hydration to earn higher wages demonstrate steadily increasing rates of AKI.
本纵向研究评估了美国农业工人随时间推移的肾功能和急性肾损伤（AKI）情况。
我们从 2020 年 1 月至 2022 年 8 月对佛罗里达州的农业工人进行了随访，在五次访问期间收集了工作日前后的血液和尿液样本。
所有参与者的工作日前估计肾小球滤过率功能在夏季较低，但随时间相对稳定。在几乎仅在蕨类植物种植场（计件薪酬）工作的参与者中，我们观察到 2020 年工作日后 AKI 的高发率（21%），到研究结束时增加到 43%。相比之下，11%的苗圃工人（计时薪酬）出现了 AKI，且该比率相当稳定。
根据农业工作类型的不同，AKI 的风险随时间而异。为了获得更高的工资而被激励放弃休息和补水的计件工人，AKI 的发病率稳步上升。
