Objective Investigate the prevalence of the symptom of dizziness in the population of Minas Gerais according to Sample Survey of Households, as well as describe the profile of interviewed individuals and the association between dizziness and socioeconomic, demographic features and health status. Methods This was a cross-sectional observational study that analyzed individuals with dizziness symptom reported in the previous month.

Among individuals who reported dizziness, 94% were adults or elderly (p ≤ 0.001) and 63% were females (p = 0.003). A statistically significant association (p < 0.001) was observed between the response variable and the variables: self-perceived health, hypertension, heart disease, diabetes, depression, seeking or requiring medical or health care in the previous month and private health care plan or insurance. Among individuals with dizziness, 84.2% sought or required medical or health care and 80.1% did not have a private health plan or insurance in the assessed period.
