Migraine and other headache syndromes in Brazil: an epidemiological analysis over the last 5 years
Abstract
Background: Migraine is one of the most common neurological conditions in the population, significantly impacting the quality of life of those affected. In Brazil, the types of headache syndromes vary epidemiologically, affecting health policies and resource allocation. Understanding the epidemiological differences between regions to identify distribution profiles is essential for developing strategies to control the current scenario of headache syndromes in the country. Objective: To analyze the epidemiological profile of patients affected by migraine and other headache syndromes in Brazil between 2019 and 2023. Methods: This is an ecological, cross-sectional, and descriptive study with a quantitative approach, based on secondary data from the Department of Informatics of the Unified Health System (DATASUS), recorded from 2019 to 2023 in Brazil. The following variables were analyzed: region, deaths per year, mortality rate, gender, ethnicity, and age group. Results: In 2019, there were 11,996 hospitalizations, decreasing to 8,778 in 2020 and 8,505 in 2021. They then increased to 10,293 in 2022 and 11,697 in 2023, totaling 51,269 over the period. The Northeast led with 15,864 hospitalizations, followed by the Southeast (14,946). The most affected age group was 30-39 years old (9,295). In the Northeast, hospitalizations were concentrated in the 30-39 age group (2,898). In the Southeast, the 30-39 age group was prominent (2,866). In the South, there was a peak in the 30-39 age…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 17,685 participants or records.
