Objective.本横断面研究在社区样本中检测职业任务与放射学和症状性骨关节炎（OA）的相关性。来自约翰斯顿县骨关节炎项目的参与者（n = 2729）自我报告了在有史以来最长的工作中执行10项特定职业任务的频率（从不/很少/有时vs经常/总是），以及终身暴露于需要花费超过50%的时间执行5项特定任务或每周10次举起22磅，44磅或110磅的工作。多变量logistic回归模型分别检查了每项职业任务与影像学和症状性膝关节和髋关节OA的相关性，控制了年龄、种族、性别、体重指数、既往膝关节或髋关节损伤和吸烟。影像学髋关节和膝关节OA与任何职业任务均无显著相关性，但几种职业任务与症状性膝关节和髋关节OA的几率增加相关：举起> 10磅、爬行和站立时做重活（OR 1.4-2.1）。更多的职业行走和站立以及更少的坐姿也与症状性膝关节OA相关，更多的弯曲/扭转/伸展与症状性髋关节OA相关。在最长的工作时间内暴露于大量体力要求较高的职业任务与症状性膝关节和髋关节OA的可能性更大相关。结论。我们的研究结果证实了体力要求高的职业任务与症状性膝关节和髋关节OA的相关性，包括几种增加两个关节组OA几率的特定活动。这些任务代表了通过预防性干预措施查明和针对高危个人的可能性。（2010年2月15日首次发布; J Rheumol 2010;37：842-50; doi：10.3899/jrheum.090302）
Objective. This cross-sectional study examined associations of occupational tasks with radiographic and symptomatic osteoarthritis (OA) in a community-based sample.Methods. Participants from the Johnston County Osteoarthritis Project (n = 2729) self-reported the frequency of performing 10 specific occupational tasks at the longest job ever held (never/seldom/sometimes vs often/always) and lifetime exposure to jobs that required spending > 50% of their time doing 5 specific tasks or lifting 22, 44, or 110 pounds 10 times weekly. Multivariable logistic regression models examined associations of each occupational task separately with radiographic and symptomatic knee and hip OA, controlling for age, race, gender, body mass index, prior knee or hip injury, and smoking.Results. Radiographic hip and knee OA were not significantly associated with any occupational tasks, but several occupational tasks were associated with increased odds of both symptomatic knee and hip OA: lifting > 10 pounds, crawling, and doing heavy work while standing (OR 1.4-2.1). More occupational walking and standing and less sitting were also associated with symptomatic knee OA, and more bending/twisting/reaching was associated with symptomatic hip OA. Exposure to a greater number of physically demanding occupational tasks at the longest job was associated with greater odds of both symptomatic knee and hip OA.Conclusion. Our results confirm an association of physically demanding occupational tasks with both symptomatic knee and hip OA, including several specific activities that increased the odds of OA in both joint groups. These tasks represent possibilities for identifying and targeting at-risk individuals with preventive interventions. (First Release Feb 15 2010; J Rheumatol 2010;37:842-50; doi: 10.3899/jrheum.090302)
