To investigate the association between occupational risk factors and the incidence of knee disorders in a young adult population.
Israeli recruits to the Israel Defense Forces go through a rigorous medical investigation. Study participants were classified by prior knee condition status and divided into 5 categories of prospective occupational exposure to physical activity according to their assigned military duties, and were then followed for 30 months for the development of severe knee disorders (SKD). Logistic regression analysis was used to estimate the occupational risks for incident SKD, adjusted for any previous mild or moderate disorder, body mass index, and body height at induction.
The study population consisted of 76,491 males. SKD developed in 615 (0.8%). Compared to administrative workers as referents, a higher risk of developing SKD was manifest among high intensity combat occupations, (odds ratios [OR] 2.15), those in moderate intensity combat occupations (OR 2.57) and maintenance (OR 1.59). Drivers did not demonstrate increased risk of knee disorders compared to referents.
Occupational factors during military service are associated with incident SKD, even when taking into account previous knee disorders, body mass index, and height, which also had independent effects in our study population.
调查年轻成年人群中职业风险因素与膝关节疾病发病率之间的关联。
以色列国防军的新兵要接受严格的医学检查。研究参与者根据既往膝关节状况进行分类，并根据其分配的军事任务分为5类预期职业体力活动暴露水平，然后随访30个月，观察严重膝关节疾病（SKD）的发生情况。采用逻辑回归分析估计发生SKD的职业风险，并对既往任何轻度或中度疾病、体重指数和入伍时的身高进行校正。
研究人群包括76491名男性。615人（0.8%）发生了SKD。与行政工作人员作为对照相比，高强度战斗职业（优势比[OR]2.15）、中等强度战斗职业（OR 2.57）和维修人员（OR 1.59）发生SKD的风险更高。与对照相比，司机未显示膝关节疾病风险增加。
即使考虑到既往膝关节疾病、体重指数和身高，兵役期间的职业因素仍与SKD的发生有关，这些因素在我们的研究人群中也有独立影响。
