Background: Chronic musculoskeletal pain (CMP) is a key cause of health loss worldwide. Cultural factors may affect pain processing and it is key to have more information regarding CMP epidemiology in Latin America. Objectives: We aimed to determine the prevalence of CMP and Chronic Widespread Pain (CWP) in Chile and to explore risk factors. Methods: We used data recollected in the 2017 Chilean National Health Survey. Using COPCORD we defined CMP as non-traumatic pain for more than three months. CWP was defined by the presence of CMP in five body regions. Associations between CMP and CWP and risk factors was investigated through univariate and multivariate logistic regression models. Results: After excluding subjects with missing information our final sample was 4045 subjects. CMP was present in 21,8% (95% CI 19,6%, 24,1%) and CWP in 4.2% (95% CI 3,3%, 5,1%). Significant risk factors for CMP in multivariate analysis were older age, female gender, lower educational level, and depressive symptoms. Protective factors for CMP were not being married and moderate alcohol consumption. CWP shared risk factors with CMP. (Table 1) Table 1.

Female gender, older age, depressive symptoms and diabetes were the main risk factors associated with chronic pain, while moderate alcohol consumption was found to be protective.
