Back pain is a typical condition, and the association among sleep disorders, sleep duration and back pain is currently being investigated. The purpose of this research is to explore the connection between sleep disorders, sleep duration and chronic back pain as well as confounding factors.
Our data were obtained from the National Health and Nutrition Examination Survey (NHANES) data set of the USA and 1,131 participants were included in the study. Multivariable logistic regression was employed to investigate the relationship between sleep disorders, sleep duration and chronic back pain. And subgroup analysis conducted by gender, age, race, education, marital status, PIR, BMI, awakening events, hypertension condition and diabetes condition was also performed.
Our study includes 1131 participants, 513 are men (45.4%) and 618 are women (54.6%), 151 participants with sleep disorders (13.4%) and 980 participants without (86.6%). The fully adjusted model with adjustment variables including age, gender, race, BMI, PIR, drink, smoke, education, marital status, awakening conditions, hypertension, diabetes and part of back pain constructed through multiple logistic regression shows that chronic back pain is associated with sleep disorders [OR = 3.71, 95% CI: (1.25, 10.99), p < 0.05]. Using normal sleep duration as a reference, there is no statistical difference between short sleep duration [OR=-0.35, 95% CI: (-0.95, 0.24), p = 0.241], long sleep duration [OR = 0.81, 95% CI: (-1.61, 3.24), p = 0.513] and chronic back pain. It can be found through subgroup analysis that age between 40 and 60 years, age larger than 60 years, different race, marital status and BMI >30 kg/m2 are associated with chronic back pain and sleep disorders. We also find a nonlinear relation which is likely to be rotated S-shape among chronic back pain and sleep duration by fitting smooth curves.
Our results suggest a substantial positive relationship between chronic back pain and sleep disorders and there is no statistical association between sleep duration and chronic back pain. The findings drawn from our study provide a basis for future exploration of the causal association between chronic back pain and sleep disorders, and provide references for timely elimination of interfering factors.
背痛是一种常见病症，目前正在研究睡眠障碍、睡眠时间与背痛之间的关系。本研究旨在探讨睡眠障碍、睡眠时间与慢性背痛之间的关系以及混杂因素。
我们的数据来自美国国家健康和营养调查（NHANES）数据集，共纳入 1131 名参与者。采用多变量逻辑回归分析睡眠障碍、睡眠时间与慢性背痛之间的关系，并按性别、年龄、种族、教育程度、婚姻状况、身体质量指数（BMI）、收入与消费比值（PIR）、觉醒事件、高血压状况和糖尿病状况进行亚组分析。
本研究共纳入 1131 名参与者，其中 513 名为男性（45.4%），618 名为女性（54.6%）；151 名参与者患有睡眠障碍（13.4%），980 名参与者无睡眠障碍（86.6%）。通过多变量逻辑回归构建的完全调整模型，调整变量包括年龄、性别、种族、BMI、PIR、饮酒、吸烟、教育程度、婚姻状况、觉醒状况、高血压、糖尿病和部分背痛，结果显示慢性背痛与睡眠障碍有关[比值比（OR）=3.71，95%置信区间（CI）：（1.25，10.99），p<0.05]。以正常睡眠时间为参考，睡眠时间过短[OR=-0.35，95%CI：（-0.95，0.24），p=0.241]和过长[OR=0.81，95%CI：（-1.61，3.24），p=0.513]与慢性背痛之间均无统计学差异。通过亚组分析发现，40-60 岁和大于 60 岁年龄组、不同种族、婚姻状况和 BMI>30kg/m2与慢性背痛和睡眠障碍有关。我们还发现慢性背痛和睡眠时间之间存在非线性关系，通过拟合平滑曲线，可能呈旋转 S 形。
本研究结果表明，慢性背痛与睡眠障碍之间存在显著的正相关关系，睡眠时间与慢性背痛之间无统计学关联。本研究结果为进一步探讨慢性背痛与睡眠障碍之间的因果关系提供了依据，为及时消除干扰因素提供了参考。
