Insomnia in college students has a significant impact on academic performance and mental health (e.g., depression). Although the mechanisms underlying insomnia and chronic pain are becoming clearer, only a few studies on college students have examined these factors by their location in the body. The purpose of the present study was to identify the location of chronic pain in the body most associated with insomnia in college students. A web-based survey was used to collect information pertaining to nine questions from 494 university students: sex, age, presence of chronic pain, intensity of chronic pain, location of chronic pain, and duration of chronic pain, as well as scores from the Athens Insomnia Scale (AIS), Pain Catastrophizing Scale, and Hospital Anxiety and Depression Scale. To examine the association between insomnia and the site of chronic pain, stepwise logistic regression analysis was conducted with AIS as the target variable. The results showed a significant positive correlation between chronic pain in the lumbar region and AIS scores. Future longitudinal studies including multiple factors are necessary to clarify the causal relationship between insomnia and chronic lower back pain.
