Abstract: Objective: To understand the current risk status of occupational lower back pain among ICU nurses, and to analyze the relationship between knowledge hiding, non compliant tasks, and the risk of lower back pain. Methods: Convenience sampling method was used to select intensive care unit nurses working in two tertiary grade A hospitals in Urumqi from March 17, 2024 to June 23, 2024 as the research subjects. The knowledge hiding scale, non compliant task scale, and nurse lower back pain prediction scale were used for investigation. Results: The knowledge hiding score of 324 ICU nurses was 24.00 (15.00, 30.00) points, the non compliant task score was 24.00 (15.00, 30.00) points, and the nurse's risk score for lower back pain was 113.08 (104.21, 133.97) points. The score of non compliant tasks was positively correlated with the score of knowledge hiding (P<0.001), and the score of knowledge hiding was positively correlated with the score of low back pain risk prediction (P<0.001). The mediating effect of knowledge hiding between non compliant tasks and the risk of lower back pain accounted for 53.49% of the total effect. Conclusion: Knowledge hiding behavior among ICU nurses is a mediating variable between non compliant tasks and the risk of lower back pain. Hospital managers should provide ICU nurses with physical and mental attention, reduce knowledge hiding behavior, enhance knowledge exchange and sharing, and reduce the risk of back pain while avoiding non compliant tasks.

摘要： 目的：了解 ICU 护士职业性腰背痛发生风险现状，分析知识隐藏行为、不合规任务与腰背痛发生风险之间的关系。方法：采用便利抽样法，选取 2024 年 3 月 17 日至 2024 年 6 月 23 日在乌鲁木齐市 2 所三级甲等医院工作的重症监护室护士为研究对象。 采用知识隐藏量表、不合规任务量表和护士腰背痛发生预测量表进行调查。结果：342 名 ICU 护士知识隐藏行为评分为 24.00 （15.00，30.00）分、不合规任务评分为 24.00（15.00，30.00）分、护士腰背痛发生风险评分为 113.08（104.21，133.97）分。不合规任务总分与知识隐藏行为总分、腰背痛风险预测总分呈正相关（P<0.001），知识隐藏行为总分与腰背痛风险预测总分呈正相关（P< 0.001）。知识隐藏行为在不合规任务与腰背痛发生风险间的中介效应占总效应的 53.49%。结论：ICU 护士知识隐藏行为是不合规任务与腰背痛发生风险的中介变量，医院管理者应在避免不合规任务发生同时给予 ICU 护士身心上的关注，以减少知识隐藏行为，增强知识交流和共享，减少腰背痛发生风险。
