很少有流行病学研究调查保管员的工作暴露与受伤风险之间的关系。对 581 名学校管理员进行了为期 4 年的调查，研究了伤害风险与职业体力需求（例如推/拉、举重）和学校环境特征（例如学校类型、季节）之间的关系。在最终的泊松回归模型中，受伤风险与以剂量反应方式进行推/拉任务所花费的时间相关，在暴露的最高四分位中风险增加至五倍（风险比 - 5.15，95% CI 1.00，26.5）。与夏季相比，受伤风险还与学年期间的工作、在草地与砾石场地的学校工作以及在独立教室的学校工作有关。结果有助于确定干预措施，例如地板清洁的替代方法，以减少保管工作的推/拉需求，并支持独立教室和草地表面替代方案的决策。相关性声明：本研究探讨了与学校保管人员受伤风险相关的人体工学因素（物理需求暴露、学校环境特征）。研究结果有助于学校采取有针对性的干预措施，以减少与伤害相关的身体需求，并设计学校环境以减少接触。
Few epidemiological studies have investigated the relationship between work exposures and injury risk among custodians. The relationship between injury risk and occupational physical demands (e. g. pushing/pulling, lifting) and school environment characteristics (e. g. school type, season) was investigated among a cohort of 581 school custodians over a 4-year period. In the final Poisson regression models, the risk of injury was associated with time spent in pushing/pulling tasks in a dose-response manner increasing to a five-fold risk among the highest quartile of exposure (risk ratio - 5.15, 95% CI 1.00, 26.5). Injury risk was also associated with working during the school year compared to the summer, working in a school with grass vs. gravel grounds and working in a school with detached classrooms. Results help to target interventions such as alternative methods for floor cleaning to reduce the pushing/pulling demands of custodial work and to support decisions for alternatives to detached classrooms and grass surfaces.Statement of Relevance: This study examines ergonomic factors (physical demand exposures, school environment characteristics) associated with injury risk among custodial school workers. The findings help schools to target interventions to reduce the physical demands associated with injuries and to design school environments to reduce exposures.
