To examine the associations of prolonged sedentary time (ST) with disease severity in women with fibromyalgia, and to analyse the combined association of total ST and prolonged ST with the disease severity in this population. Women ( = 451; 51.3 ± 7.6 years old) with fibromyalgia participated. Sedentary time and moderate-to-vigorous physical activity (MVPA) were measured using triaxial accelerometry and ST was processed into 30- and 60-min bouts. Dimensions of fibromyalgia (function, overall, symptoms) and the overall disease impact were assessed with the Revised Fibromyalgia Impact Questionnaire (FIQR). Body fat percentage was assessed using a bio-impedance analyser, and physical fitness was assessed with the Senior Fitness Tests Battery. Greater percentage of ST in 30-min bouts and 60-min bouts were associated with worse function, overall, symptoms and the overall impact of the disease (all, < 0.05). Overall, these associations were statistically significant when additionally controlling for MVPA and overall physical fitness. Participants with low levels of total ST and prolonged ST (>60-min bouts) presented lower overall impact compared to participants with high levels of total ST and prolonged ST (mean difference = 6.56; 95% confidence interval (CI) = 1.83 to 11.29, = 0.002). Greater percentage of ST accumulated in 30- and 60-min bouts and a combination of high levels of total and prolonged ST are related to worse disease severity. Although unable to conclude on causality, results suggest it might be advisable to motivate women with fibromyalgia to break prolonged ST and reduce their total daily ST.
为研究久坐时间延长（ST）与纤维肌痛女性疾病严重程度之间的关联，并分析总ST和久坐时间延长与该人群疾病严重程度的联合关联。纳入了患有纤维肌痛的女性（n = 451；年龄51.3±7.6岁）。使用三轴加速度计测量久坐时间和中度至剧烈身体活动（MVPA），并将ST处理为30分钟和60分钟的时间段。使用修订的纤维肌痛影响问卷（FIQR）评估纤维肌痛的维度（功能、总体、症状）和总体疾病影响。使用生物电阻抗分析仪评估体脂百分比，并通过老年人健身测试组合评估身体素质。30分钟时间段和60分钟时间段内ST占比更高与功能、总体、症状以及疾病的总体影响更差相关（均P<0.05）。总体而言，在额外控制MVPA和总体身体素质后，这些关联具有统计学意义。与总ST和久坐时间延长水平高的参与者相比，总ST和久坐时间延长水平低的参与者（>60分钟时间段）的总体影响更低（平均差异=6.56；95%置信区间（CI）=1.83至11.29，P = 0.002）。30分钟和60分钟时间段内积累的ST占比更高以及总ST和久坐时间延长水平高的组合与更差的疾病严重程度相关。尽管无法得出因果关系，但结果表明，建议激励纤维肌痛女性打破久坐时间延长的状态并减少其每日总ST。
