This study aimed to: evaluate the epidemiology of CP in the general population in an Italian area; and assess the awareness of a specific law, unanimously approved in Parliament, which provides citizens the right to access pain management ­(Italian Law 38/2010). Methods: A cross-sectional population-based study carried out during the spring of 2014 at Narni, Umbria, Italy. All the citizens residing in that area, aged >18, were enrolled in the study. Outcome measures were: prevalence of CP and therapies. The awareness of the Italian Law 38/2010 was also recorded. Results: Data of 1293 questionnaires were analyzed. The prevalence of CP was 28.4%. In 51.5% of cases, pain was severe, with higher prevalence in females (p<0.001). Moreover, pain was generally increasing with age (p<0.001). The risk of suffering from severe pain was modeled using logistic regression. Significant predictors were female gender (OR 2.59; 95% CI: 1.77–3.79), living in an urban area (OR 0.63; 95% CI 0.45–0.88), and age (OR 1.06; 95% CI: 1.04–1.08). Among people with CP, 77.9% were receiving therapy; the proportion of individuals in therapy for severe pain significantly increased with age (OR 1.03; 95% CI: 1.02–1.05) and was smaller in individuals with light pain (OR 0.21; 95% CI: 0.07–0.66). The majority of subjects (61.9%) are not aware of the existence of a specific law stating their rights to receive pain management. Conclusion: CP, at least in the rural part of the community investigated in Italy, is not perceived as a chronic disease in its own right. A socio-cultural transformation in patients and in the health care system seems necessary. Keywords: cross-sectional study, chronic pain, palliative care, pain therapy, pain control&nbsp
