Prevalence of chronic pain in Brazil: a descriptive study

Abstract

BACKGROUND AND OBJECTIVES: Very little is known about the epidemiology of chronic pain in Brazil; especially in the case of multiple pain prevalence surveys. Knowing about the prevalence of chronic pain in the Brazilian population is an important step in revealing the scope and magnitude of its effects, providing a guide to preventive and intervention strategies, mainly public policies. The objective is to review descriptively the publications made in Brazil to estimate the prevalence of chronic pain in the Brazilian population.
