Chronic musculoskeletal pain (CMP) is a global health condition that affects thousands of people. CMP can substantially affect the functional capacity and quality of life of the people impacted, resulting in high costs for health care and social security systems. Sociodemographic factors may play a significant role in pain chronification prevention and control programs. Thus, current risk factors for CMP must be seriously considered as part of an interdisciplinary management strategy. The purpose of the study was to identify the primary sociodemographic characteristics of CMP patients at a multidisciplinary and specialized center for chronic pain. This is a retrospective investigation based on a review of medical records. Age, gender, income, and the time of onset of pain symptoms were among the variables included in the analyzed data. To analyze variables related to the duration of discomfort, a multiple regression model was utilized. Sociodemographic factors explained 37.94% of experiencing prolonged pain, according to the study’s findings. Being female and having a family income above the minimum wage were variables that were directly proportional to discomfort duration. Age was not associated with a prolonged duration of pain perception.
