Retinal detachment (RD) has been associated with exposure to heavy lifting. Many occupations within the construction industry are likely to involve lifting tasks. We investigated the association between occupational heavy lifting and rhegmatogenous RD in a retrospective cohort study of Swedish construction workers.
We studied Swedish construction workers who participated in an industry-wide health and safety program from 1971 to 1993. Individual occupation codes were linked to a job exposure matrix, assigning intensity of exposure to heavy lifting to each worker. The Swedish National Patient Register was used to identify cases of RD that occurred during follow-up through the end of 2012. We used Poisson regression modeling to calculate incidence rates of RD associated with heavy lifting, age and other covariates. A subcohort of those age ≤25 years at enrollment was studied to reduce bias from missing exposure information from work prior to enrollment.
Of 256 241 construction workers, 17% were classified with high exposure to heavy lifting in their occupation. Within the cohort, 1588 cases of RD were identified. Average exposure intensity of heavy lifting was not associated with risk of RD. However, RD risk increased with increasing cumulative exposure to heavy lifting, both in the full cohort and subcohort of those who were ≤25 years old at entry into the construction-worker cohort.
Construction workers' risk of RD appeared to increase with time spent exposed to heavy lifting.
视网膜脱离（RD）与重物抬举暴露有关。建筑行业的许多职业可能都涉及举重任务。我们在一项对瑞典建筑工人的回顾性队列研究中调查了职业性重物抬举与孔源性 RD 之间的关联。
我们研究了 1971 年至 1993 年期间参加了一项全行业健康和安全计划的瑞典建筑工人。个体职业代码与职业暴露矩阵相关联，为每个工人分配重物抬举的暴露强度。瑞典国家患者登记处用于通过 2012 年底的随访来识别 RD 病例。我们使用泊松回归模型计算与重物抬举、年龄和其他协变量相关的 RD 发生率。研究了年龄≤25 岁的参与者亚组，以减少因在参加建筑工人队列之前的工作中暴露信息缺失而导致的偏倚。
在 256241 名建筑工人中，17%的人在其职业中被归类为高暴露于重物抬举。在该队列中，共发现了 1588 例 RD。平均重物抬举暴露强度与 RD 风险无关。然而，无论是在全队列还是在≤25 岁进入建筑工人队列的参与者亚组中，RD 风险都随着重物抬举的累积暴露量的增加而增加。
建筑工人患 RD 的风险似乎随时间推移暴露于重物抬举而增加。
