Low back pain (LBP) is a common health condition that is often associated with disability, psychological distress and work loss. Worldwide, billions of dollars are expended each year trying to manage LBP, often with limited success. Recently, some researchers have reported that LBP patients also report sleep disturbance as a result of their LBP. However, as most of this evidence was obtained from highly selected groups of patients or from studies with small samples, high quality data on prevalence of sleep disturbance for patients with LBP are lacking. It is also unclear whether sleep disturbance is more likely to be reported by patients with recent-onset LBP than by patients with persistent LBP. Finally, it is not known whether high pain intensity, the most relevant condition-specific variable, is associated with higher rates of reported sleep disturbance. The present study aimed to determine the prevalence of reported sleep disturbance in patients with LBP. In addition, we aimed to determine whether sleep disturbance was associated with the duration of back pain symptoms and whether pain intensity was associated with reported sleep disturbance. Data from 1,941 patients obtained from 13 studies conducted by the authors or their colleagues between 2001 and 2009 were used to determine the prevalence of sleep disturbance. Logistic regression analyses explored associations between sleep disturbance, the duration of low back symptoms and pain intensity. The estimated prevalence of sleep disturbance was 58.7% (95% CI 56.4-60.7%). Sleep disturbance was found to be dependent on pain intensity, where each increase by one point on a ten-point visual analogue scale (VAS) was associated with a 10% increase in the likelihood of reporting sleep disturbance. Our findings indicate that sleep disturbance is common in patients with LBP. In addition, we found that the intensity of back pain was only weakly associated with sleep disturbance, suggesting that other factors contribute to sleep problems for LBP patients.
下背痛（LBP）是一种常见的健康状况，通常与残疾、心理困扰和工作损失有关。在全球范围内，每年都有数以亿计的资金用于尝试管理 LBP，但往往收效甚微。最近，一些研究人员报告称，LBP 患者也会因 LBP 而出现睡眠障碍。然而，由于大多数证据来自高度选择的患者群体或来自样本量较小的研究，因此缺乏 LBP 患者睡眠障碍流行率的高质量数据。目前尚不清楚睡眠障碍是否更有可能由新发 LBP 患者报告，而不是由持续性 LBP 患者报告。最后，尚不清楚高疼痛强度（最相关的特定于疾病的变量）是否与更高的睡眠障碍报告率相关。本研究旨在确定 LBP 患者报告的睡眠障碍的流行率。此外，我们还旨在确定睡眠障碍是否与背部疼痛症状的持续时间有关，以及疼痛强度是否与报告的睡眠障碍有关。本研究使用作者或其同事在 2001 年至 2009 年期间进行的 13 项研究中获得的 1941 名患者的数据，以确定睡眠障碍的流行率。逻辑回归分析探讨了睡眠障碍、下背部症状持续时间和疼痛强度之间的关联。睡眠障碍的估计流行率为 58.7%（95%CI56.4-60.7%）。睡眠障碍与疼痛强度有关，在 10 点视觉模拟量表（VAS）上增加一个点，报告睡眠障碍的可能性增加 10%。我们的研究结果表明，睡眠障碍在 LBP 患者中很常见。此外，我们发现背部疼痛的强度仅与睡眠障碍轻度相关，这表明其他因素也会导致 LBP 患者出现睡眠问题。
