Profile and prevalence of people with tinnitus: a health survey

PURPOSE

To estimate the prevalence and characterize the health profile, and tinnitus complaint, of the adult population of a health district in Campinas, in the State of São Paulo.

METHODS

A in-service survey was conducted in all health centers in the district with a random approach to the adult population seeking care at the unit. The sample consisted of 1,720 people, including 1,569 subjects who agreed to participate in the survey and answered a questionnaire including questions on general health and tinnitus. Two regression models were performed according to the variables and a 5% significance level was was adopted for the statistical analysis.

RESULTS

496 people reported tinnitus, representing a prevalence of 31.6%. Most of the sample was female, had at least one chronic disease and made continuous use of some medication. Respondents reported hearing complaints and the most common type of tinnitus was reported as unilateral, intermittent and acute. The regression models performed showed a higher chance of tinnitus with advancing age and with the occurrence of diabetes and thyroid disorder.

CONCLUSION

Tinnitus is related to the occurrence of chronic diseases and advancing age, may cause discomfort and is a reason for seeking treatment. Further population studies are required in different contexts in the Brazilian scenario.

Sensitivity and specificity of a low-cost screening protocol for identifying children at risk for language disorders

OBJECTIVES

To compare the diagnostic accuracy of a low-cost screening test for identifying children at risk for language disorders with that of a specific language assessment.

METHODS

The study was conducted during a polio vaccination campaign in basic health units in western São Paulo, Brazil. The parents/guardians of 1000 children aged between 0 and 5 years were asked to answer questions of a specific screening test. The instrument consisted of a uniform set of questions about the main milestones in language development (from 0 to 5 years of age) with scaled scores to assess responses. There were no exclusion criteria. After the screening test, the children were referred to a specific language assessment by ABFW, following a determined flow of referrals. The results obtained in the screening were compared to those obtained in the specific language assessment; then, the sensitivity, specificity, accuracy, and positive and negative predictive values were determined for the screening test. Children who failed the screening test also underwent an audiological evaluation. The statistical significance was set at 5%.

RESULTS

The majority of the participants were aged between 4 and 5 years (21.82%) and were male (51.6%). The sensitivity and specificity values were 82.5% and 98.93%, respectively. The area under the curve was 0.907 (0.887-0.925), and the screening test showed 96% accuracy.

CONCLUSIONS

The screening test showed high diagnostic efficiency in determining the risk of language disorders in children aged between 0 and 5 years.

Dental status, oral prosthesis and chewing ability in an adult and elderly population in southern Brazil

OBJECTIVE

The objective of this study was to explore the factors associated with inadequate chewing in an adult and elderly population of a city in the southern region of Brazil.

METHODS

This was a cross-sectional study based on a population home-based inquiry (DCH-POP) in southern Brazil. Individuals were interviewed by trained interviewers to create a standardized procedure. In a pilot study, the Questionnaire of Human Communication Disorders (DCH-POP) was created and validated to identify self-reported speech and language, swallowing and hearing disorders. The outcome was dichotomized into either having adequate chewing or not, as assessed by a series of questions about chewing ability. Analyses of absolute and relative frequencies were measured according to the studied variables. A Poisson regression was applied at a significance level of 5%.

RESULTS

A total of 1,246 people were interviewed. Inadequate chewing was found in 52 (5.6%) individuals, with a higher prevalence in the elderly (11.8%) than in adults (5.2%). In the final model, the following factors were associated with inadequate chewing: being 61 years of age or older (prevalence ratio or PR=9.03; 95% CI: 1.20-67.91), loss of teeth and use of unadjusted prosthesis (PR=3.50; 95% CI: 1.54-7.95), preference for foods of soft consistency (PR=9.34; 95% CI:4.66-8.70) and difficulty in nasal breathing (PR=2.82; 95% CI: 1.31-6.06).

CONCLUSION

Age, oral health status through dental prosthesis, preference for foods of soft consistency and difficulty breathing through the nose were factors associated with chewing inability in adults and the elderly.

Análise da prevalência de perda auditiva autodeclarada e fatores associados: informante primário versus proxy

O objetivo foi avaliar diferenças entre as prevalências de perda auditiva autodeclarada e fatores associados, obtidas nas respostas de informantes primário e proxy no Estudo de Distúrbios da Comunicação Humana de Base Populacional (DCH-POP). Trata-se de um estudo de métodos em epidemiologia, utilizando dados de um inquérito domiciliar do tipo transversal, com uma amostra de 1.253 indivíduos do Sul do Brasil. Para verificar diferenças de prevalências entre informantes primários e informante proxy foram utilizados os testes qui-quadrado ou exato de Fisher para variáveis categóricas, e Mann-Whitney para as contínuas. Ainda, o modelo log-binomial foi ajustado para a variável dependente perda auditiva considerando-se três conjuntos de dados: toda a amostra, apenas informantes primários e apenas informantes proxy, estimando-se as associações por meio da razão de prevalências. Nos modelos finais, apenas as variáveis independentes idade e tontura estiveram associadas com o desfecho de perda auditiva independentemente do conjunto de dados utilizado. Em geral, informantes proxy subestimaram as prevalências dos desfechos estudados em relação aos informantes primários.

Prevalência autorreferida de deficiência no Brasil, segundo a Pesquisa Nacional de Saúde, 2013

Resumo Objetivo descrever a prevalência autorreferida das deficiências intelectual, física, auditiva e visual, segundo variáveis sociodemográficas, grau de limitação e frequência de uso de serviço de reabilitação. Métodos Dados provenientes da Pesquisa Nacional de Saúde, inquérito populacional. Foram calculadas as prevalências autorreferidas de deficiência física, mental, visual e auditiva e seus intervalos de confiança de 95%, estratificados por sexo, faixa etária, raça/cor, para Brasil, local de residência e Grandes Regiões. Resultados a prevalência de deficiência autorreferida no país foi de 6,2% (12,4 milhões de pessoas). A prevalência de deficiência física foi de 1,3%, maior em homens, em indivíduos com 60 anos ou mais na região Nordeste. A deficiência visual foi mais prevalente (3,6%), aumentou com a idade, assim como deficiência auditiva. A deficiência adquirida foi maior em relação à de nascença (exceto intelectual). Menor grau de limitação foi observado entre os que referiram deficiência visual e o uso de serviços de saúde foi menos frequente. Conclusão há necessidade de ampliar o acesso às ações de promoção, diagnóstico e tratamento precoce, bem como o fortalecer políticas públicas direcionadas a esta população.
