The purpose of this study was to investigate whether there is a bidirectional relationship between pain and insomnia symptoms over the course of a year.
A longitudinal design with a 1-year follow-up was used.
From a randomly selected sample of the adult general population (N= 3,000), 1,746 individuals filled out a baseline and 1-year follow-up survey on pain, insomnia symptoms, anxiety symptoms, and depressive symptoms.
Pain (OR = 1.64) and anxiety symptoms increased the risk for the incidence of insomnia symptoms (R(2) = .125) and pain (OR = 1.98), anxiety symptoms and depressive symptoms were related to the persistence of insomnia symptoms (R(2) = .212). Gender and anxiety symptoms increased the risk for the incidence of pain (R(2) = .073); and age, insomnia symptoms (OR = 1.49), anxiety symptoms, and depressive symptoms were associated with the persistence of pain (R(2) = .187).
While pain was linked to future insomnia symptoms and insomnia symptoms to the persistence of pain over the course of a year, insomnia symptoms was not associated with the incidence of pain. The results, thus, partly argue against bidirectionality between pain and insomnia symptoms.
本研究旨在探讨疼痛和失眠症状在一年内是否存在双向关系。
采用纵向设计，随访 1 年。
从成年普通人群中随机抽取样本（N=3000），1746 人填写基线和 1 年随访调查，内容包括疼痛、失眠症状、焦虑症状和抑郁症状。
疼痛（OR=1.64）和焦虑症状增加了失眠症状（R(2)=.125）和疼痛（OR=1.98）发生的风险；焦虑症状和抑郁症状与失眠症状的持续存在相关（R(2)=.212）。性别和焦虑症状增加了疼痛发生的风险（R(2)=.073）；年龄、失眠症状（OR=1.49）、焦虑症状和抑郁症状与疼痛的持续存在有关（R(2)=.187）。
虽然疼痛与未来的失眠症状有关，失眠症状与疼痛的持续存在有关，但失眠症状与疼痛的发生无关。因此，研究结果部分反对疼痛和失眠症状之间的双向关系。
