BACKGROUND
This study's objective was to quantify exposure-response relationships between job physical exposure (JPE) and incidence of lateral epicondylitis (LE).
METHODS
A cohort of 536 workers was enrolled from 10 manufacturing facilities and followed monthly for 6 years to ascertain changes in JPE and health status. JPE was individually measured and quantified using the Strain Index (SI) and TLV for HAL. Worker demographics, medical history, psychosocial factors, and current musculoskeletal disorders were obtained.
RESULTS
Fifty-six workers developed LE. In multivariate models JPE, age, family problems, and swimming were associated with increased risk of LE. SI showed an exposure-response relationship with maximum hazard ratio (HR) of 4.5(P = 0.04). TLV for HAL showed a non-statistically significant trend for increased risk of LE (P = 0.19).
CONCLUSION
JPE is associated with increased risk of LE. The SI and TLV for HAL are useful metrics for estimating JPE.
背景
本研究旨在量化工作体力暴露（JPE）与外侧上髁炎（LE）发病之间的暴露-反应关系。
方法
从 10 家制造工厂招募了一个由 536 名工人组成的队列，并对其进行了为期 6 年的每月随访，以确定 JPE 和健康状况的变化。使用应变指数（SI）和 HAL 的 TLV 对工人进行个体测量和量化。收集工人的人口统计学、病史、心理社会因素和当前肌肉骨骼疾病的数据。
结果
56 名工人患上了 LE。在多变量模型中，JPE、年龄、家庭问题和游泳与 LE 风险增加有关。SI 显示出与最大危害比（HR）为 4.5（P=0.04）的暴露-反应关系。HAL 的 TLV 显示出 LE 风险增加的非统计学显著趋势（P=0.19）。
结论
JPE 与 LE 的风险增加有关。SI 和 HAL 的 TLV 是估计 JPE 的有用指标。
