Multiple factors influence the recovery process of low back pain (LBP). The identification and increased knowledge of risk factors might contribute to a better understanding of the course of LBP.
To investigate the association of habitual physical activity (PA) and sedentary behaviour (SB), measured at baseline, with disability trajectories in adults with LBP.
A prospective cohort study where habitual PA levels were measured using the Short QUestionnaire to ASsess Health enhancing physical activity (SQUASH), SB was calculated as average sedentary hours per day, and LBP disability using the Oswestry Disability Index (ODI). Participants completed the questionnaires at one and a half, three, six, and twelve months. Linear mixed models were estimated to describe the association of habitual PA levels SB measured at baseline with disability trajectories. Other predictors were gender, education level, age, pain, number of previous episodes of LBP, and duration of LBP.
Habitual SB measured at baseline in adults (n = 347) with LBP were not associated with disability trajectories. For PA, participants with one metabolic equivalent of task (MET) hour per day above average recovered 0.04 [95% CI 0.004 to 0.076] points on the ODI per month faster than participants with an average amount of MET hours per day.
Habitual SB was not associated with LBP disability trajectories over a one-year follow-up. High levels of habitual PA at baseline were associated with improved recovery in LBP disability trajectory, but the finding is not clinically relevant.
多种因素影响腰痛（LBP）的恢复过程。识别风险因素并增加对其的了解可能有助于更好地理解LBP的病程。
研究在基线时测量的习惯性身体活动（PA）和久坐行为（SB）与LBP成年患者残疾轨迹之间的关联。
一项前瞻性队列研究，使用简短健康增强身体活动调查问卷（SQUASH）测量习惯性PA水平，将SB计算为每天平均久坐小时数，并使用Oswestry残疾指数（ODI）评估LBP残疾情况。参与者在1.5个月、3个月、6个月和12个月时完成问卷。采用线性混合模型来描述在基线时测量的习惯性PA水平和SB与残疾轨迹之间的关联。其他预测因素包括性别、教育水平、年龄、疼痛、既往LBP发作次数和LBP持续时间。
在患有LBP的成年人（n = 347）中，基线时测量的习惯性SB与残疾轨迹无关。对于PA，每天比平均代谢当量任务（MET）小时数多1小时的参与者，每月在ODI上的恢复速度比每天平均MET小时数的参与者快0.04[95%CI 0.004至0.076]分。
在一年的随访中，习惯性SB与LBP残疾轨迹无关。基线时高水平的习惯性PA与LBP残疾轨迹的恢复改善相关，但这一发现不具有临床相关性。
