Abstract
ABSTRACT BACKGROUND AND OBJECTIVES: The prevalence of the fibromyalgia syndrome has been estimated in some Brazilian cities and regions, and previous population-based studies investigating this prevalence, as well as the profile of medical consultations are unknown. METHODS: This study used the database constructed by a previous study of authors to identify the prevalence of chronic pain in Brazil. The cases that reported pain for more than 6 months and with a diagnosis of fibromyalgia were selected. The studied descriptive variables were age, intensity and frequency of pain, pain interference in self-care, walking, working, social life, sexual life, sleep quality, if pain causes sadness or depression or influences the emotional aspects. The total sample was evaluated by rheumatologists and pain-expert doctors. RESULTS: Thirteen cases from the initial database were selected since they reported the diagnosis of the prevalence of the fibromyalgia syndrome representing 2% of the initial study population, average age 35.8 years (9.8). The predominance of the fibromyalgia syndrome was in females (n=11). Pain intensity was 7.3 (2.4), the frequency and duration of pain were constant in the majority of the sample (n=9). Most of the cases report a serious pain interference with sleep (n=8), many said that pain interferes with the work (n=5), irritability (5) and finally, some report that pain has a moderate interference in self-care (n=5), walking (n=6), social life (n=6), sexual life (n=5) and causes moderate sadness or depression (n=5). CONCLUSION: The prevalence of the fibromyalgia syndrome was estimated in 2% of the Brazilian population, based on secondary data of a study on chronic pain prevalence in Brazil. The data was collected in 2015-2016. The most reported complaints were intense and daily pain that interferes with sleep.
Highlights
Chronic pain is recognized as a public health problem
Brazilian studies estimate the prevalence of fibromyalgia syndrome (FMS) around 2.5%4
This study aimed to describe the profile of the Brazilian population with FMS
Summary
Chronic pain is recognized as a public health problem. The high prevalence and indicators of an increase in the incidence of chronic pain, such as fibromyalgia syndrome (FMS)[1], generateSouza JB and Perissinotti DM questions about diagnosis, therapeutic approach, and intensity of symptoms reported by patients[2]. FMS is not the most prevalent chronic pain worldwide or in Brazil It is the focus of much research and study because of the complex clinical picture and because it is costly to the health system. The prevalence of the fibromyalgia syndrome has been estimated in some Brazilian cities and regions, and previous population-based studies investigating this prevalence, as well as the profile of medical consultations are unknown. RESULTS: Thirteen cases from the initial database were selected since they reported the diagnosis of the prevalence of the fibromyalgia syndrome representing 2% of the initial study population, average age 35.8 years (9.8). CONCLUSION: The prevalence of the fibromyalgia syndrome was estimated in 2% of the Brazilian population, based on secondary data of a study on chronic pain prevalence in Brazil. The most reported complaints were intense and daily pain that interferes with sleep
