In Brazil there are few published studies that study, the prevalence, symptoms and the population's knowledge about the premenstrual syndrome of women of reproductive age, and that correlate these data with the sociodemographic conditions of these women. In addition, given the complexity of the diagnosis of PMS, the prevalence of PMS in the Brazilian female population may be lower than the self-reported and published in these works, since not all women who believe they suffer from PMS fully comply with the criteria contemplated in the consensus for diagnosis of PMS. In this sense, this study aims to analyze the prevalence and intensity of frequent symptoms of PMS reported by the Brazilian female population. The information generated with this study may help to rethink behaviors to improve the health and quality of life of these women, as well as offer tools for decision making related to the need for early and effective treatment of PMS, whose disorders are associated with both the fall present and future quality of life for women, as well as all of their family, social and professional coexistence.
