Low back pain (LBP) is one of the world's most prevalent health issues. Patients with LBP experience various intensities and durations of symptoms, which can lead to distinctive course patterns commonly described as symptom trajectories.
This study aimed to investigate the association between different amounts of physical activity and sedentary behavior and the trajectory of LBP, in people with a lifetime history of LBP.
The study involved a secondary analysis of observational longitudinal data collected from the AUstralian Twin low BACK pain (AUTBACK) study.
A total of 329 individual twins met the inclusion criteria for analysis. Latent Class Growth Analysis was used to identify distinct patterns of LBP and select the primary outcome (probability of having a severe LBP trajectory, 0%-100%). Linear regression models were used to investigate the association between different amounts of physical activity or sedentary behavior at baseline, and the probability of having a severe LBP trajectory. Results were expressed as β coefficients and 95% confidence intervals (CI).
Moderate-to-vigorous intensity physical activity was significantly associated with the probability of having a severe LBP trajectory (unadjusted β -0.0276; 95%CI -0.0456 to -0.0097, p=.003). For every 1-minute increase in moderate-to-vigorous intensity physical activity per week, there was a 2.8%-point reduction in a participant's probability of having a severe LBP trajectory. No significant associations were identified between sedentary behavior or light intensity physical activity, and the probability of having a severe LBP trajectory.
In people with a lifetime history of LBP, engagement in higher volumes of moderate to vigorous intensity physical activity at baseline was associated with a lower probability of developing a severe trajectory of LBP over 1 year.
下背痛（LBP）是世界上最普遍的健康问题之一。患有 LBP 的患者经历各种强度和持续时间的症状，这可能导致独特的病程模式，通常被描述为症状轨迹。
本研究旨在探讨一生中患有 LBP 的人群中，不同量的体力活动和久坐行为与 LBP 轨迹之间的关系。
这项研究是对澳大利亚双胞胎腰痛（AUTBACK）研究中观察性纵向数据的二次分析。
共有 329 名符合分析标准的个体双胞胎。使用潜在类别增长分析来识别 LBP 的不同模式，并选择主要结局（发生严重 LBP 轨迹的概率，0%-100%）。线性回归模型用于研究基线时不同量的体力活动或久坐行为与发生严重 LBP 轨迹的概率之间的关系。结果表示为β系数和 95%置信区间（CI）。
中等至剧烈强度体力活动与发生严重 LBP 轨迹的概率显著相关（未调整的β-0.0276；95%CI-0.0456 至-0.0097，p=.003）。每周中等至剧烈强度体力活动增加 1 分钟，参与者发生严重 LBP 轨迹的概率降低 2.8%。久坐行为或低强度体力活动与发生严重 LBP 轨迹的概率之间没有显著关联。
在有一生 LBP 病史的人群中，基线时进行更高量的中等至剧烈强度体力活动与在 1 年内发展为严重 LBP 轨迹的概率降低相关。
