A preliminary exploration of the construct validity of the Berlin questionnaire as a measure of obstructive sleep apnoea in a South African population : a clinical health psychology perspective.

Baker, Michelle Lydia. January 2006 (has links)
Clinical professionals in South Africa are generally unaware of the impact of obstructive sleep apnoea (OS A). The cost to the state of untreated apnoea may be extremely high. In primary health care encounters OSA often goes undiagnosed. The cascade of symptoms linked to OSA is profound, placing patients at risk for debilitating problems impacting on self and others. The aim of this study was to validate a questionnaire, which could be used at a primary health care level to identify patients with OSA thus cutting costs and improving efficient, effective and ethical service to patients. The Berlin Questionnaire (BQ) (Netzer et al. 1999) was administered to a clinical sample of consenting patients at a private sleep laboratory in Durban, South Africa (N = 119)(completed n = 110). Home-based sleep studies (n = 116) on a portable cardio-respiratory screening device were also obtained for objective comparison. From the results obtained in this South African sample, the BQ showed low validity and reliability (Cronbach a = 0.62 - 0.84) to individual items of the BQ. The total BQ score and high-risk symptom category analysis showed mildly significant correlations with internationally approved protocols. The BQ identified 60% of the high-risk group (AHI >5). Furthermore, risk categories were useful in predicting AHI ratings in 64% of moderate OSA cases and 25% of severe OSA cases. The BQ therefore has useful psychometric properties as an adjunct assessment tool to screen for high-risk OSA cases where resources are scant. Clinical health psychologists are in an ideal position to recognise the risk factors and symptoms of OSA. The clinical assessment and the value of the correct diagnosis will alleviate the treatment of psychological symptoms at a superficial level in primary health care facilities. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Secretaria Municipal de Saúde / Unimed Volta Redonda / Introdução: A síndrome da apneia obstrutiva do sono (SAOS) é uma doença crônica, progressiva, com alta morbimortalidade. Encontra-se subdiagnosticada, principalmente entre mulheres. Objetivo: Estudar a prevalência de alto risco para SAOS globalmente e para as categorias do Questionário de Berlim (QB), e sua associação a fatores de risco. Métodos: Estudo observacional, transversal de indivíduos cadastrados no Programa Médico de Família de Niterói, selecionados aleatoriamente, com idade entre 45 e 99 anos com coleta entre agosto/2011 a dezembro/2012. Variáveis associadas com cada uma das categorias e com o alto risco para SAOS (global) foram incluídas em modelos de regressão logística com valor p<0,05. Resultados: Do total (616), 403 (65,4%) disseram roncar. A prevalência de alto risco para SAOS foi de 42,4%, 49,7% para categoria1, 10,2% para categoria2 e 77,6% para categoria3. Conclusão: O QB apresentou uma confiabilidade aceitável quando retiradas as perguntas alguém notou que você para de respirar quando está dormindo e cochilar/dormir ao volante, o que deve ser testado em estudos com populações com maioria de mulheres e de baixa escolaridade. Dado o peso das doenças e riscos associadas a SAOS, seria importante haver futuras investigações para validar novos instrumentos ou aperfeiçoar o QB para melhor rastreamento da SAOS / Introduction: The obstructive sleep apnea (OSA) is a chronic, progressive disease with high mortality. It is underdiagnosed, especially among women. Objective: To study the prevalence of high risk for OSA globally and the Berlin Questionnaire categories (QB), and its association with risk factors. Methods: Observational, cross-sectional study with individuals from Niterói Family Medical Program, randomly selected, aged between 45 and 99 years with visits between August / 2011 to December / 2012. Variables associated with each category and with the high risk for OSA (global) were included in logistic regression models with p <0.05. Results: Of the total (616), 403 (65.4%) said to snore. The prevalence of high risk for OSA was 42.4%, 49.7% for category1, 10.2% for category2 and 77.6% for Category3. Conclusion: The QB showed an acceptable reliability when the questions anyone noticed that you stop breathing when sleeping and nap / sleep behind the wheel were dropped, which should be tested in studies of populations with most women and low education. Given the burden of disease and risks associated with OSA, it would be important to future research to validate new tools or improve the QB to better screening for OSA

Qualidade do sono em portadores de doença arterial coronariana crônica / Sleep Quality in Patients with Chronic Coronary Artery Disease

Espinheira, Patrícia Farias Sá 20 September 2013 (has links)
Background: Sleep disorders have been considered risk factors for cardiovascular disease, including coronary artery disease (CAD). Therefore, poor sleep quality should be frequent complaint in patients with coronary disease. However, in patients with CAD, the prevalence of poor sleepers and factors associated were not properly investigated. Objectives: To evaluate the frequency and the factors associated with poor sleepers in patients with chronic CAD. Method: We used validated questionnaires to examine sleep quality (Pittsburgh Sleep Quality Index; PSQI), high risk of obstructive sleep apnea (Berlin Questionnaire; BQ), excessive sleepiness (Epworth Sleepiness Scale; ESS), angina-related health status (Seattle Angina Questionnaire; SAQ) and quality of life (Medical Outcomes Study 36-item Short Form; SF-36) in 257 volunteers with stable CAD, mean age 62.5 ± 10.5 years. We categorized and compared good and poor sleepers, according to PSQI global score. Subsequently, adjusted analysis was performed to investigate the factors associated with poor sleepers and demographics, clinical characteristics, risk for obstructive sleep apnea, excessive sleepiness, angina-related health status and quality of life. Results: The majority of CAD patients (75.1%) were poor sleepers. The adjusted analysis indicated that older patients (OR 1.05, 95% CI 1.02 to 1.09; p = 0.004), women gender (OR 3.09, 95% CI 1.48 to 6.45; p = 0.003), lower ejection fraction (OR 1.04, 95% CI 1.01 to 1.06; p = 0.015), lower physical limitation (OR 1.03, 95% CI 1.00 to 1.05; p = 0.020), lower angina stability (OR 1.02, 95% CI 1.00 to 1.04; p = 0.027), worse angina-related quality of life (OR 1.03, 95% CI 1.01 to 1.05; p = 0.002) and lower vitality (OR 1.02, 95% CI 1.00 to 01.03; p = 0.042) were associated with poor sleepers. Conclusion: Poor sleepers were highly frequency in chronic CAD patients. Patients with chronic CAD and poor sleepers present higher age, women gender, lower ejection fraction, higher physical limitation, lower angina stability, lower angina-related quality of life and lower vitality. / Introdução: Distúrbios do sono têm sido considerados fatores de risco para doença cardiovascular, inclusive para doença arterial coronariana (DAC). Portanto, qualidade do sono ruim deve ser queixa frequente em portadores de doença coronariana. Entretanto, em portadores de DAC, a prevalência de qualidade do sono ruim e os fatores associados não foram devidamente investigados. Objetivos: Avaliar a prevalência e investigar os fatores associados à qualidade do sono ruim em pacientes portadores de DAC crônica. Métodos: Foram utilizados questionários validados para examinar a qualidade do sono (Índice de Qualidade de Sono de Pittsburgh; PSQI), o alto risco para apneia obstrutiva do sono (Questionário de Berlim; QB), a sonolência excessiva (Escala de Sonolência de Epworth; ESE), o status funcional relacionado à angina (Questionário de Seattle sobre Crise de Angina; QSA) e a qualidade de vida relacionada à saúde (Questionário de Qualidade de Vida SF-36; SF-36), em 257 voluntários com DAC crônica, com idade média de 62,5 ± 10,5 anos. Os pacientes foram categorizados em dois grupos, boa qualidade do sono e qualidade do sono ruim, de acordo com a pontuação global do PSQI. Posteriormente, foi realizada a análise multivariada para investigar a associação entre qualidade do sono ruim e fatores demográficos, características clínicas gerais, risco para apneia obstrutiva do sono, sonolência excessiva, status funcional relacionado à angina e qualidade de vida relacionada à saúde. Resultados: A maioria dos pacientes com DAC crônica (75,1%) apresentaram qualidade do sono ruim. A Análise multivariada indicou que pacientes com idade avançada (OR 1.05, IC 95% 1.02 - 1.09; p = 0,004), gênero feminino (OR 3.09, IC 95% 1.48 - 6.45; p = 0,003), menor fração de ejeção (OR 1.04, IC 95% 1.01 - 1.06; p = 0,015), maior limitação física (OR 1.03, IC 95% 1.00 - 1.05; p = 0,020), menor estabilidade da angina (OR 1.02, IC 95% 1.00 - 1.04; p = 0,027), pior qualidade de vida relacionada à angina (OR 1.03, IC 95% 1.01 - 1.05; p = 0,002) e menor vitalidade (OR 1.02, IC 95% 1.00 - 1.03; p = 0,042), foram associados à qualidade do sono ruim. Conclusão: Qualidade do sono ruim foi altamente frequente em pacientes com DAC crônica. Pacientes portadores de DAC crônica e pior qualidade do sono apresentam maior probabilidade de serem mais idosos, do gênero feminino, apresentarem menor fração de ejeção, maior limitação funcional, menor estabilidade da angina, pior qualidade de vida relacionada à angina e menor vitalidade.
