Abstract
in English, Portuguese

Introduction: The state of Minas Gerais, Brazil has no data on the prevalence of dizziness in the population and this information can be fundamental as the basis of public health policies, promotion, prevention and rehabilitation campaigns.

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. The data entered in the Sample Survey of Households of 2011 were analyzed. An independent statistical association was determined between the selected variables and dizziness through multivariate analysis.

Results: Dizziness was the third major complaint among individuals who mentioned any health problems in the previous month, with an estimated population of 209,025 individuals and reported by 6.7% of symptomatic ones, with higher prevalence values only reported for the symptoms of fever and headache. 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.

Conclusion: The dizziness symptom was highly prevalent in the population of Minas Gerais during the assessed month of the investigation. Dizziness was prevalent in adults and the elderly and showed a statistical association with socioeconomic and demographic characteristics, as well as the assessed health status.

Introdução: O estado de Minas Gerais–Brasil não possui dados sobre a prevalência de tontura na população e estas informações podem ser fundamentais para basear políticas de saúde pública, campanhas de promoção, prevenção e a reabilitação.

Objetivo: Investigar a prevalência do sintoma de tontura na população do estado de Minas Gerais segundo a Pesquisa por Amostra de Domicílio (PAD-MG), assim como descrever o perfil dos indivíduos entrevistados e as relações entre tontura e características socioeconômicas, demográfica e condições de saúde.

Método: Estudo de caráter observacional transversal com análise dos indivíduos com relato de sintoma de tontura no último mês. Foram analisados os dados inseridos na PAD-MG de 2011. Determinou-se associação estatística independente entre as variáveis selecionadas e a tontura por intermédio de análise multivariada.

Resultados: A tontura foi à terceira queixa principal entre os indivíduos que mencionaram algum problema de saúde no último mês, com estimativa populacional de 209.025 indivíduos e relatada por 6,7% dos sintomáticos, com valores inferiores somente aos sintomas de febre e dores de cabeça, respectivamente. Dentre indivíduos com relato de tontura, 94% são adultos ou idosos (p ≤ 0,001) e 63% do sexo feminino (p = 0,003). Foi encontrada associação estatisticamente significante (p < 0,001) entre a variável resposta e as variáveis autopercepção de saúde, hipertensão, doenças cardíacas, diabetes, depressão, procura ou necessidade de atendimento médico ou de saúde no último mês e presença de cobertura de plano ou seguro-saúde. Dentre os indivíduos com tontura, 84,2% procurou ou precisou de atendimento médico ou de saúde e 80,1% não possuíam cobertura de plano ou seguro-saúde no período pesquisado.

Conclusão: O sintoma de tontura se mostrou altamente prevalente na população de Minas Gerais no mês de referência da pesquisa. A tontura foi prevalente nos indivíduos adultos e idosos e apresentou associação estatística com as características socioeconômicas, demográficas e condições de saúde estudadas.
