Passive sedentary behavior (SB) may lead to adverse health outcomes; however, it remains unclear whether the factors relevant to passive SB differ between older adults with and without knee osteoarthritis (KOA). This cross-sectional study examined factors associated with passive SB among 688 community-dwelling older women with ( = 128) and without ( = 560) KOA. Passive SB (min/day) was assessed using the Japanese-translated version of the Measure of Older Adults' Sedentary Time questionnaire. Demographic, lifestyle, and psychosocial factors; pain; and physical performance were evaluated in multiple regression models with an interaction term concerning SB between the two groups. The mean (SD) total SB for those without and with KOA was 490.4 (200.9) min/day and 487.4 (185.8) min/day, respectively, and the majority of SB was passive, with no difference between groups. Passive SB was associated with an obese status and less time spent in group activities. However, no KOA-specific SB factors were identified. Therefore, effective interventions to promote social participation and weight loss, especially for individuals with obesity, may reduce passive SB, regardless of KOA. Longitudinal studies are warranted to identify causal relationships.
被动久坐行为（SB）可能导致不良健康后果；然而，对于患有和不患有膝骨关节炎（KOA）的老年人，与被动 SB 相关的因素是否不同，目前仍不清楚。这项横断面研究调查了 688 名社区居住的老年女性（KOA 组=128 人，无 KOA 组=560 人）中与被动 SB 相关的因素。使用日本翻译的老年人久坐时间问卷评估被动 SB（min/天）。在多回归模型中评估了人口统计学、生活方式和心理社会因素；疼痛；以及物理性能，其中考虑了两组之间 SB 的交互项。无 KOA 和有 KOA 的参与者的总 SB 平均值（SD）分别为 490.4（200.9）min/天和 487.4（185.8）min/天，且大部分 SB 为被动 SB，两组之间无差异。被动 SB 与肥胖状态和参与群体活动的时间减少有关。然而，没有发现特定于 KOA 的 SB 因素。因此，促进社会参与和减肥的有效干预措施可能会减少被动 SB，无论是否存在 KOA。需要进行纵向研究以确定因果关系。
