We investigated the influence of different types of lifetime occupation on knee osteoarthritis (OA) and pain based on a nationwide survey in Korea.
We conducted a cross-sectional study using Korea National Health and Nutrition Examination Survey (KNHANES) from 2010 to 2012. Men ≥50 years old were divided into four occupational groups: white-collar (WC) workers, pink-collar (PC) workers, blue-collar (BC) workers, and agribusiness and low-level (AL) workers. The risks for knee OA and pain development according to occupation were compared to the risks in WC workers, using multiple logistic regression analyses.
Different occupations were associated with different levels of risk for knee OA and knee pain. The risk for knee OA was higher in BC workers and in AL workers than in WC workers, in order of higher risk. The risk for severe knee OA was likewise higher in AL workers and in BC workers, in order of higher risk. The risk for chronic knee pain was higher in AL workers, BC workers, and PC workers, in order of higher risk. The risk for moderate to severe chronic knee pain was higher in AL workers and BC workers, in order of higher risk.
The results suggest that occupation might affect the development of knee OA and presence of chronic knee pain in men ≥50 years old. WC workers are least affected by knee OA and chronic knee pain, and AL and BC workers are at clearly higher risk for knee OA and chronic knee pain.
我们基于韩国全国性调查，研究了不同类型的终身职业对膝骨关节炎（OA）和疼痛的影响。
我们使用韩国国家健康和营养检查调查（KNHANES）在 2010 年至 2012 年进行了一项横断面研究。≥50 岁的男性被分为四组职业：白领（WC）工人、粉领（PC）工人、蓝领（BC）工人和农业及低水平（AL）工人。使用多因素逻辑回归分析比较了不同职业与膝 OA 和疼痛发展的风险。
不同的职业与膝 OA 和膝痛的风险水平不同。与 WC 工人相比，BC 工人和 AL 工人患膝 OA 的风险更高，风险依次递增。同样，严重膝 OA 的风险在 AL 工人和 BC 工人中更高，风险依次递增。慢性膝痛的风险在 AL 工人、BC 工人和 PC 工人中更高，风险依次递增。中重度慢性膝痛的风险在 AL 工人和 BC 工人中更高，风险依次递增。
结果表明，职业可能会影响≥50 岁男性膝 OA 和慢性膝痛的发展。WC 工人受膝 OA 和慢性膝痛的影响最小，而 AL 和 BC 工人患膝 OA 和慢性膝痛的风险明显更高。
