ABSTRACT Purpose: to analyze the impact of neck pain, neck mobility, and body mass index on teachers’ postural control. Methods: a cross-sectional study with 54 state public school teachers, 68.5% (n = 37) being females, with a mean age of 46.5 ± 9.3 years. Data were collected with the following instruments: Craniocervical Dysfunction Index (Brazilian version), force platform in bipedal and semi-tandem stance, visual analog scale, cervical mobility index, and body mass index. Data were analyzed with nonparametric statistics and multiple linear regression; the significance level was set at p<0.05, with 95% confidence intervals. Results: teachers with neck pain and severely impaired neck mobility had greater postural control changes in the semi-tandem stance. In the bipedal stance, those with mild mobility changes and neck pain had a smaller total displacement. Obese teachers had a smaller movement amplitude in the anteroposterior and mediolateral directions. Conclusion: teachers presented with neck pain and severely impaired neck mobility had a worse postural control. Obese teachers had a smaller total amplitude in both movement directions.

RESUMO Objetivo: analisar o impacto da cervicalgia, mobilidade cervical e índice de massa corporal no controle postural de professores. Métodos: estudo transversal com 54 professores da rede estadual de ensino, com média de idade de 46,5 ± 9,3 anos, dos quais: 68,5% (n = 37) eram do sexo feminino. A coleta de dados teve como base os seguintes instrumentos: Craniocervical Dysfunction Index (versão brasileira), plataforma de força na posição bipodal e semitandem, escala visual analógica, índice de mobilidade cervical e índice de massa corporal. Para análise dos dados, foi utilizada estatística não paramétrica e análise de regressão linear múltipla, com nível de significância p<0,05 e intervalo de confiança de 95%. Resultados: os professores com cervicalgia e comprometimento severo da mobilidade cervical tiveram maior alteração do controle postural na posição semitandem. Na posição bipodal, aqueles com leve alteração da mobilidade e dor cervical apresentaram menor deslocamento total, assim como professores obesos demostraram menor amplitude de movimento nas direções anteroposterior e médio-lateral. Conclusão: os professores com cervicalgia e comprometimento severo da mobilidade cervical tiveram pior controle postural. Já os obesos apresentaram menor amplitude total em ambas as direções do movimento.

RESUMO Objetivo: verificar possível associação da perda auditiva com disfonia, hipertensão arterial (HA), diabetes mellitus (DM), doenças da tireoide e queixas de ruído. Métodos: estudo transversal envolvendo 60 professores, média de idade de 47,05 anos. Foi avaliada a audição por meio da Audiometria tonal limiar, a percepção e qualidade vocal com o questionário vocal e a avaliação vocal acústica, enquanto a queixa de ruído e as comorbidades envolvidas foram investigadas com o questionário padronizado. A análise estatística utilizou os testes Ex-act de Mann Whitney, Fisher e regressão linear multivariada. Resultados: houve associação significante entre perda auditiva e DM, HA e doenças da tireoide (ambas p <0,0001), mas não foi encontrada associação entre queixa de ruído e perda auditiva nesta população. A regressão mostrou que as variáveis disfonia (p = 0,0311) e DM (p = 0,0302) são fatores de risco independentes para perda auditiva. Houve correlação entre perda auditiva e as características vocais rugosidade, soprosidade, tensão e ressonância. Conclusão: este estudo demostrou que HA e doenças da tireoide são fatores associados a perda auditiva, além disso a disfonia e DM se constituem em fatores associados independentes para a perda auditiva em professores. Estes resultados mostram a necessidade de políticas direcionadas a promoção da saúde do professor.

ABSTRACT Objective: to verify a possible association between hearing loss and dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints. Methods: a cross-sectional study involving 60 teachers, mean age 47.05 years. Pure-tone threshold audiometry was used to assess hearing, the voice questionnaire and voice acoustic evaluation were used for voice perception and quality, and the standardized questionnaire verified noise complaint and comorbidities. The statistical analysis was conducted with Mann-Whitney and Fisher's exact tests and multivariate linear regression. Results: there was a significant association between hearing loss and diabetes mellitus, hypertension, and thyroid disease (both p <0.0001), but there was no association between noise complaints and hearing loss in this population. The regression showed that dysphonia (p = 0.0311) and diabetes mellitus (p = 0.0302) are independent risk factors for hearing loss. A correlation was found between hearing loss and voice characteristics: roughness, breathiness, tension, and resonance. Conclusion: this study showed that hypertension and thyroid diseases are factors associated with hearing loss. In addition, dysphonia and diabetes mellitus are independent factors associated with hearing loss in teachers. These results show the need for policies aimed at promoting teachers’ health.

Abstract Introduction Physical inactivity is an important risk factor for many aging-related symptoms. Studies suggest that physical activitymay help to relieve tinnitus and headache. Objective To investigate the presence of tinnitus and headache in elderly individuals by associating it with the lack of regular physical activity. Methods A cross-sectional study including elderly individuals who live independently. The practice of physical activity and the complaints of headache and of tinnitus were checked by means of a questionnaire with objective questions. The statistical analysis was performed using the chi-squared test and relative risk, and a multiple logistic regression model was used to determine how well each factor predicted headache while controlling for each of the other factors. Results Based on a sample of 494 subjects, it was found that 213 (43.11%) complained of tinnitus. Among the complainants, 97 (45.53%) practiced physical activity regularly. We have confirmed associations between headache with lack of physical activity among elderly individuals with tinnitus (p = 0.0440). It was also observed that certain factors, such as male gender and tinnitus, are independent factors for the complaint of headache. Conclusion We have found that headache could be a symptom related to the lack of regular physical activity among elderly individuals with tinnitus.

Abstract Introduction Functional disorders of the craniocervical region affect 77.78% of Brazilian teachers. Among the most common instruments used to assess craniocervical disorders in a detailed and objective way, none had been translated to Brazilian Portuguese and adapted to Brazilian culture. Objectives To translate to Brazilian Portuguese and to culturally adapt the Craniocervical Dysfunction Index (CDI). Method The first phase of the study consisted of the translation, synthesis, backtranslation, and review of the contents by a committee of experts, who developed a trial version and sent all the steps to the original author. The trial version was applied to 50 teachers of an institution. The reliability and internal consistency were evaluated by Cronbach α. For the validation, the Brazilian Portuguese version of the CDI was correlated with the Visual Analogue Scale (VAS) domains for cervicalgia and evaluated by Spearman ρ. Result Some expressions were adapted to the Brazilian culture. Among the participants who did not report neck pain in the VAS, 84.21% suffered from craniocervical dysfunction acording to the CDI. Among the participants who reported neck pain in the VAS, 100% suffered from craniocervical dysfunction according to the CDI. The CDI showed good internal consistency and satisfactory reliability measured by Cronbrach α (α = 0.717). There was a strong correlation between the CDI and the VAS score (ρ = 0.735). Conclusion No difficulties were encountered in the translation and back-translation of the CDI, and no problems were observed regarding the trial version developed; therefore, the Brazilian Portuguese version of the CDI is a valid and reliable instrument to evaluate the functional alteration of the craniocervical region.
