Although knee bending has been indicated to have worse effects on developing knee osteoatrhritis (OA), we are not aware of the relation of sitting upright, a Japanese own style of sitting, with knee OA.In the present study, the Japanese Buddhist priests who acquired the position at two major temples in Shiga prefecture, Japan, between 1965 and 1985 were selected as the cohort. As control, male subjects who previously responded to the health care examination held by the local community and who were recorded as having no custum of sitting upright.History-taking and physical examination were performed and radiogrphs were taken for both cohort and control subjects. Osteoarthritis was defined in two separate manners : those satisfying the ACR classification criteria or those who had radiographic K-L score of grades 2 or more were defined as having knee OA.Odds ratio and 95% confidence interval were calculated by logistic regression analysis.Our study showed that the custom of sitting upright had no significant relation with knee OA.The results were essentially similar when the analysis was adjusted for confounders such as age, height, weigt and history of knee trauma.

虽然屈膝对膝骨性鼻炎(OA)的发生有较大影响，但我们尚不清楚直立坐姿与膝骨性鼻炎的关系。在本研究中，选择1965-1985年间在日本滋贺县两个主要寺庙获得这一职位的日本佛教僧侣作为队列。对照组为以前参加过当地社区健康检查的男性受试者，被记录为没有直立坐姿的男性受试者。对队列受试者和对照组受试者进行病史记录和体格检查，并拍摄X线片。骨性关节炎有两种不同的定义方式：符合美国膝关节骨性关节炎分类标准的患者和X线K-L评分在2级或以上的患者被定义为膝关节骨性关节炎。通过Logistic回归分析计算奇数比和95%可信区间。我们的研究表明，直立坐的习惯与膝关节骨性关节炎没有显著关系。当调整年龄、身高、体重和膝关节外伤史等混杂因素时，结果基本相似。
