Prevalence of Insomnia in Patients with Chronic Low Back Pain; A Cross-sectional Study

Background: A common musculoskeletal ailment that has a substantial influence on both physical and mental health is chronic low back pain. This pain is frequently linked to insomnia, which exacerbates emotional distress and pain intensity. Reduced quality of life, functional limitations, and worsening pain perception have all been connected to sleep disturbances. Finding out how common insomnia is in patients with chronic low back pain and examining the connection between the severity of insomnia and pain intensity are the objectives of this study. Objective: To determine the prevalence of insomnia in patients with chronic low back pain. Methodology: A cross-sectional study involving 65 participants who had CLBP for six months was carried out. The Oswestry Disability Index and the Numeric Rating Scale were used to measure functional disability and pain intensity, respectively, while the Insomnia Severity Index was used to measure the severity of insomnia. About 65 patients who had had chronic low back pain for longer than six months were included in the study. A confirmed diagnosis of chronic low back pain lacking radicular symptoms, being older than 18, and being able to comprehend and finish the questionnaire were requirements for inclusion. Acute low back pain, recent spinal surgery, and primary sleep disorders apart from insomnia were among the exclusion criteria. The prevalence was ascertained using descriptive statistics, and the associations between insomnia and pain parameters were evaluated using correlation analysis. Results: Among 65 participants, moderate clinical insomnia was present in 21.5%, severe clinical insomnia in 63.1%, sub-threshold insomnia in 9.2%, and no insomnia in 6.2% of cases. Higher insomnia scores were found to be significantly correlated with more severe pain, indicating that sleep disturbances may be a contributing factor to increased pain perception and disability. Conclusion: Almost 63.1% of people with CLBP suffer from severe clinical insomnia, indicating a high prevalence of insomnia in this population. The results show that sleep disturbances and pain intensity are strongly correlated, highlighting the necessity of integrated pain management strategies that take into account both physical and sleep-related factors.
