To explore the individual-independent relationships of sedentary time (ST) and physical activity (PA) (light and moderate-to-vigorous intensity (MVPA)), with sleep duration and body composition (waist circumference, body mass index (BMI), body fat percentage, and muscle mass index) in women with fibromyalgia, and to determine whether these associations are independent of physical fitness. This cross-sectional study involved 385 women with fibromyalgia. ST and PA were assessed by triaxial accelerometry, sleep duration was self-reported. Waist circumference was measured using an anthropometric tape, and body weight, body fat percentage, and muscle mass were estimated using a bio-impedance analyzer. In individual regression models, ST and sleep were directly associated with waist circumference, BMI, and body fat percentage ( between 0.10 and 0.25; all < 0.05). Light PA and MVPA were inversely associated with waist circumference, BMI, and body fat percentage ( between -0.23 and -0.12; all < 0.05). In multiple linear regression models, ST ( between 0.17 and 0.23), light PA ( between -0.16 and -0.21), and sleep duration ( between 0.11 and 0.14) were independently associated with waist circumference, BMI, and body fat percentage (all < 0.05). MVPA was associated with waist circumference independent of light physical activity (LPA) and sleep duration ( = -0.11; < 0.05). Except for MVPA, these associations were independent of physical fitness. These results suggest that longer ST and sleep duration, and lower PA levels (especially light intensity PA), are independently associated with greater adiposity, but not muscle mass, in women with fibromyalgia. These associations are, overall, independent of physical fitness.
为探讨纤维肌痛女性久坐时间（ST）和身体活动（PA）（轻度和中等到剧烈强度（MVPA））与睡眠时间及身体成分（腰围、体重指数（BMI）、体脂百分比和肌肉量指数）之间的个体独立关系，并确定这些关联是否独立于身体素质。这项横断面研究纳入了385名纤维肌痛女性。通过三轴加速度计评估ST和PA，睡眠时间通过自我报告。使用人体测量带测量腰围，使用生物电阻抗分析仪估计体重、体脂百分比和肌肉量。在个体回归模型中，ST和睡眠与腰围、BMI和体脂百分比直接相关（0.10至0.25之间；均P<0.05）。轻度PA和MVPA与腰围、BMI和体脂百分比呈负相关（-0.23至-0.12之间；均P<0.05）。在多元线性回归模型中，ST（0.17至0.23之间）、轻度PA（-0.16至-0.21之间）和睡眠时间（0.11至0.14之间）与腰围、BMI和体脂百分比独立相关（均P<0.05）。MVPA与腰围相关，独立于轻度身体活动（LPA）和睡眠时间（β=-0.11；P<0.05）。除MVPA外，这些关联独立于身体素质。这些结果表明，在纤维肌痛女性中，较长的ST和睡眠时间以及较低的PA水平（尤其是轻度强度PA）与更高的肥胖程度独立相关，但与肌肉量无关。总体而言，这些关联独立于身体素质。
