Prevalence of dizziness in the population of Minas Gerais, Brazil, and its association with demographic and socioeconomic characteristics and health status / Prevalência de tontura na população do Estado de Minas Gerais, Brasil, e suas relações com as características socioeconômicas demográficas e condições de saúde

Abstract 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.

Resumo Introdução O Estado de Minas Gerais, Brasil, não tem dados sobre a prevalência de tontura na população e essas informações podem ser fundamentais para basear políticas de saúde pública, campanhas de promoção e 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 a 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% procuraram ou precisaram de atendimento médico ou de saúde e 80,1% não tinham 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.

Triagem otoneurológica em operários da construção civil que executam trabalho em altura / Otoneurological screening of civil construction workers performing work at height

RESUMO Objetivo: avaliar a prevalência de sinais e sintomas otoneurológicos em operários da construção civil do campus saúde da Universidade Federal de Minas Gerais (UFMG) que trabalham expostos à altura. Métodos: estudo observacional transversal constituído por 33 trabalhadores da construção civil. Foi utilizado o Protocolo Ofício de Gestão de Diagnóstico Otoneurológico composto por anamnese, provas vestibulares realizadas por meio de Dix-Hallpike e nistagmo de posição, avaliação da dinâmica vestibular utilizando a prova de Head Shaking, provas de equilíbrio estático, dinâmico, cerebelares, investigação complementar dos pares cranianos, conclusão/conduta e orientação. Os dados foram lançados em planilha do programa SPSS versão 13.0, sendo consideradas significantes as diferenças que apresentaram nível de significância de até 5%. Resultados: todos os participantes eram do gênero masculino. A média de idade foi de 38,1 anos, variando de 21 a 65 anos. Um terço dos participantes apresentaram alteração na triagem devido a queixa de equilíbrio e/ou zumbido. Por meio do teste Qui-Quadrado foi possível observar diferença estatisticamente significante entre o grupo com queixa de equilíbrio para as variáveis de distúrbios circulatórios, cefaleia e uso de medicamentos, sendo que este último estatisticamente significante também no grupo com queixa de zumbido. Conclusão: um terço dos trabalhadores da construção civil que executam trabalho em altura apresentou triagem otoneurológica sugestiva de alteração.

ABSTRACT Purpose: to investigate the prevalence of otoneurological signs and symptoms in construction workers at the health campus of Universidade Federal de Minas Gerais (UFMG) that perform their functions at height. Methods: the cross-sectional observational study consisted of 33 construction workers. The Protocolo Ofício de Gestão de Diagnóstico Otoneurológico (Otoneurological Diagnosis Management Service Protocol) was used, which is composed of medical case history, vestibular tests including Dix Hallpike test and Positional Nystagmus, vestibular dynamics evaluation using Head Shaking Nystagmus test, static and dynamic balance tests, cerebellar exam, complementary investigation of the cranial nerves, completion/conduct and orientation. The data were entered into a SPSS 13.0 spreadsheet, considering significant the differences up to the level of 5%. Results: all participants were male. The average age was 38.1 years, ranging from 21 to 65 years. One third of the participants showed changes in screening due to complaints about imbalance and/or tinnitus. Chi-square test revealed a statistically significant difference in the group with complaints of imbalance in relation to the variables of circulatory dysfunctions, headache and use of medicines; the last was also statistically significant in the group with tinnitus. Conclusion: one third of the construction workers who perform work at height presented otoneurological screening results that indicate alteration.
