Abstract

Objectives: This study aimed to investigate the prevalence of radiographic hand osteoarthritis (HOA) in older Japanese individuals in three distinct regions with unique geographic and occupational characteristics and explore the regional variations and factors, including occupational workload, that affect HOA.

Methods: We analysed the radiographic images and data of 1642 participants aged ≥60 years (mean, 75.6 years). After grading the radiographs of both hands using the modified Kellgren-Lawrence (KL) classification, HOA was defined as at least one joint with a KL grade ≥2, and severe HOA was defined as at least one joint with a KL grade ≥3.

Results: The overall prevalence rates of HOA and severe HOA were 95.9% and 54.2%, respectively. Regional differences were observed: residence in the mountainous region was associated with HOA and severe HOA, whereas residence in the coastal region was associated with only HOA. Occupational workload was associated with severe HOA in a dose-dependent manner, and heavy work was associated with a higher number of osteoarthritis-affected joints.

Conclusion: The present study revealed a high prevalence of HOA in older Japanese individuals and highlighted regional variations in HOA prevalence. A higher occupational workload was associated with a higher risk of severe HOA.

地区差异和职业对手部骨关节炎的影响：来自骨关节炎/骨质疏松症与残疾研究的见解。

目的：本研究旨在调查具有独特地理和职业特征的三个不同地区的日本老年人放射性手骨关节炎（HOA）的患病率，并探讨影响HOA的地区差异和因素，包括职业工作量。方法：我们分析了1642名年龄≥60岁（平均75.6岁）的参与者的x线图像和资料。采用改良的Kellgren-Lawrence （KL）分级法对双手x线片进行分级后，HOA定义为至少一个关节的KL分级≥2，重度HOA定义为至少一个关节的KL分级≥3。结果：HOA和重度HOA的总患病率分别为95.9%和54.2%。地区差异显著：山区居住与HOA和严重HOA相关，而沿海地区居住仅与HOA相关。职业工作量与严重HOA呈剂量依赖关系，而繁重的工作与受骨关节炎影响的关节数量增加有关。结论：本研究揭示了日本老年人HOA的高患病率，并强调了HOA患病率的地区差异。较高的职业工作量与较高的严重HOA风险相关。
