title = "Epidemiological register studies on pain - etiology, treatment, and mental health",
abstract = "Pain is common in life and can be caused by trauma or underlying disease and is mostly temporary, but for some the pain can develop into a chronic pain condition. Pain leads to individual suffering as well as negative impact on the wider society. Especially since pain can start early in life and affect large parts of it. The aim of this thesis was to identify potential risk factors for chronic and widespread pain, and to study associated comorbidities and prescription drug use. This was done by using the extensive electronic health records and registers available in Sweden to perform four population-based cohort studies. Study I: We investigated the effect of rheumatoid arthritis, endometriosis, and inflammatory bowel disease, three diseases with recurrent pain as a common feature, on the risk of developing chronic pain. We showed that all three diseases were risk factors for widespread pain. Study II: We investigated the temporal relationship between pain and mental illness and found a bidirectional relationship where the two conditions increase the risk for each other. Study III: We investigated risk factors for prolonged opioid use after distal radius fracture. We found that previous opioid use, mental illness, and surgery acted as risk factors whereas occupational/physical therapy decreased the risk. Study IV: We studied trends in yearly prevalence of diagnoses for pain and mental health conditions and associated prescription drug use in adolescents and young adults. We found decreasing prevalence of pain diagnoses but a steep increase in mental health conditions and associated prescription drugs. Our results propose early identification and treatment for chronic diseases where recurrent pain is a common symptom to decrease the risk of chronic pain. Moreover, since pain and mental illness act as risk factors for each other monitoring both conditions among individuals affected by either could be beneficial to improve patient wellbeing. This is especially important since our studies also show that both pain and mental illness and associated prescription drugs are common in young people. Finally, screening for previous regular opioid use could be considered when initiating treatment for distal radius fracture. ",
