Objectives: Chronic musculoskeletal pain (CMP) causes significant health loss worldwide. Given that cultural factors may affect pain processing, it is key to have more information regarding CMP epidemiology in Latin America. In this study, we aimed to determine the prevalence of CMP and chronic widespread pain (CWP) in Chile. Methods: This was a cross-sectional survey study. We used data recollected in the 2016-2017 Chilean National Health Survey, a nationwide household survey. Our study population included subjects older than 14 years living in urban and rural Chile. We defined CMP as nontraumatic pain with a duration of longer than 3 months. Chronic widespread pain was defined by the presence of CMP in 5 body regions. The association between CMP and CWP and potential risk factors was investigated through univariate and multivariate logistic regression models. Results: After excluding subjects with missing information our final sample constituted 4045 subjects. Chronic musculoskeletal pain was present in 21.8% (95% confidence interval, 19.6%-24.1%) and CWP in 4.2% (95% confidence interval, 3.3%-5.1%). Significant risk factors in multivariate analysiswere older age, female sex, lower educational level, and depressive symptoms. Factors associated with a reduced risk of CMP were not being married and moderate alcohol consumption. Conclusions: One of 5 Chilean people has chronic pain, and 1 of 20 has CWP. Data regarding alcohol and pain have been controversial in previous studies; therefore, this decreased risk inmoderate consumers should be further explored. Chronic widespread pain shared risk factors and protective factors with CMP but with a higher magnitude of association.
