研究背景久坐行为（SB）在成人骨关节炎（OA）患者中普遍存在，它与许多不良的健康后果有关。SB和OA患者日常生理和心理健康结果之间的关联，然而，却很少受到关注。PurposeUsing accelerometer和自我报告数据，本研究探讨了OA患者在SB中花费的时间量如何与他们的疼痛和日常生活中的影响相关，而与身体活动无关。143名患有膝关节OA的老年人（平均年龄= 65岁）佩戴加速度计测量SB和身体活动，并使用手持电脑每天三次报告他们的疼痛和影响。进行多层次分析，探讨前瞻性的人内关联SB和随后的疼痛或影响在同一天内，跨天，独立的体力activity.ResultsThe SB每天花费的时间预测疼痛少，但更糟的影响，在当天结束时，以上和超越的影响，体力活动，以及人口统计学和个体差异，一般健康和抑郁症。此外，跨日滞后分析表明，在SB的第一天花费的时间预测更高的负面影响第二天早上。最后，SB的平均水平也与较差的平均影响在between-person level.ConclusionsSB可能与疼痛少，在短期内，但从患者的情绪健康减损。未来的干预应旨在减少每日SB，以改善OA患者的情绪健康。
BackgroundSedentary behavior (SB), which has been linked with numerous adverse health outcomes, is prevalent among adults with osteoarthritis (OA). The associations between SB and daily physical and psychological health outcomes for OA patients, however, have received little attention.PurposeUsing accelerometer and self-report data, the current study examined how the amount of time OA patients spent in SB was associated with their pain and affect in daily life, independent of physical activity.MethodsOver 22 days, 143 older adults (mean age = 65 years) with knee OA wore an accelerometer to measure SB and physical activity, and also reported their pain and affect three times a day using a handheld computer. Multilevel analyses were conducted to examine the prospective within-person associations between SB and subsequent pain or affect within the same day and across days, independent of physical activity.ResultsThe time spent in SB daily predicted less pain but worse affect at the end of that day, above and beyond the effects of physical activity, as well as demographics and individual differences in general health and depression. Moreover, cross-day lagged analyses indicated that time spent in SB on 1 day predicted higher negative affect the next morning. Finally, the average level of SB was also associated with worse average affect at the between-person level.ConclusionsSB may be related to less pain in the short term but detract from patients’ emotional well-being. Future intervention should aim to reduce daily SB to improve OA patients’ emotional well-being.
