          ABSTRACT

          Objective:

          To translate and perform a cross-cultural adaptation of the Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender (STOP-Bang) questionnaire so that it can be used as a screening tool for the diagnosis of obstructive sleep apnea in Brazil.

          Methods:

          Based on the principles of good practice for the translation and cross-cultural adaptation of such instruments, the protocol included the following steps: acquisition of authorization from the lead author of the original questionnaire; translation of the instrument to Brazilian Portuguese, carried out by two translators; reconciliation; back-translation to English, carried out by two English teachers who are fluent in Portuguese; review of the back-translation; harmonization; review and approval of the questionnaire by the original author; cognitive debriefing involving 14 patients who completed the questionnaire; analysis of the results; and review and preparation of the final version of the instrument approved by the review committee.

          Results:

          The final version of the STOP-Bang questionnaire for use in Brazil showed a clarity score > 9 (on a scale of 1-10) for all of the questions. The Cronbach's alpha coefficient was 0.62, demonstrating the internal consistency of the instrument. The means and standard deviations of the age, body mass index, and neck circumference of the patients studied were 46.8 ± 11.2 years, 43.7 ± 8.5 kg/m 2, and 41.3 ± 3.6 cm, respectively.

          Conclusions:

          The STOP-Bang questionnaire proved to be understandable, clear, and applicable. The original instrument and the translated version, cross-culturally adapted for use in Brazil, were consistently equivalent. Therefore, it can become a widely used screening tool for patients with suspected obstructive sleep apnea.

          Resumo

          Objetivo:

          Realizar a tradução e adaptação transcultural do questionário Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender (STOP-Bang) para a língua portuguesa falada no Brasil, de forma a possibilitar sua aplicação como instrumento de triagem para o diagnóstico da apneia obstrutiva do sono.

          Métodos:

          Embasado nos princípios de boas práticas para a tradução e adaptação transcultural desses instrumentos, o protocolo incluiu os seguintes passos: obtenção de autorização da autora principal do questionário original; tradução, realizada por dois tradutores; reconciliação; tradução retrógrada realizada por dois professores de inglês procedentes de países de língua inglesa e fluentes na língua portuguesa; revisão da tradução retrógrada; harmonização; revisão e aprovação do questionário pela autora original; desdobramento cognitivo com 14 pacientes que responderam ao questionário; análise dos resultados; e revisão e preparação da versão final do instrumento pelo comitê revisor.

          Resultados:

          A versão final do questionário STOP-Bang traduzida para a língua portuguesa falada no Brasil apresentou uma média de clareza > 9 (em uma escala de 1-10) em todas as questões. O coeficiente alfa de Cronbach foi de 0,62, demonstrando a consistência interna do instrumento. As médias e desvios-padrão da idade, do índice de massa corpórea e da circunferência de pescoço dos pacientes foram de, respectivamente, 46,8 ± 11,2 anos, 43,7 ± 8,5 kg/m² e 41,3 ± 3,6 cm.

          Conclusões:

          O questionário STOP-Bang mostrou-se compreensível, claro e aplicável. Houve consistência na equivalência do questionário original com o traduzido e adaptado para uso no Brasil, podendo esse se tornar um instrumento de triagem amplamente utilizado para pacientes com suspeita de apneia obstrutiva do sono.

          Sleep disordered breathing and mortality: eighteen-year follow-up of the Wisconsin sleep cohort.

          Sleep-disordered breathing (SDB) is a treatable but markedly under-diagnosed condition of frequent breathing pauses during sleep. SDB is linked to incident cardiovascular disease, stroke, and other morbidity. However, the risk of mortality with untreated SDB, determined by polysomnography screening, in the general population has not been established. An 18-year mortality follow-up was conducted on the population-based Wisconsin Sleep Cohort sample (n = 1522), assessed at baseline for SDB with polysomnography, the clinical diagnostic standard. SDB was described by the number of apnea and hypopnea episodes/hour of sleep; cutpoints at 5, 15 and 30 identified mild, moderate, and severe SDB, respectively. Cox proportional hazards regression was used to estimate all-cause and cardiovascular mortality risks, adjusted for potential confounding factors, associated with SDB severity levels. All-cause mortality risk, adjusted for age, sex, BMI, and other factors was significantly increased with SDB severity. The adjusted hazard ratio (HR, 95% CI) for all-cause mortality with severe versus no SDB was 3.0 (1.4,6.3). After excluding persons who had used CPAP treatment (n = 126), the adjusted HR (95% CI) for all-cause mortality with severe versus no SDB was 3.8 (1.6,9.0); the adjusted HR (95% CI) for cardiovascular mortality was 5.2 (1.4,19.2). Results were unchanged after accounting for daytime sleepiness. Our findings of a significant, high mortality risk with untreated SDB, independent of age, sex, and BMI underscore the need for heightened clinical recognition and treatment of SDB, indicated by frequent episodes of apnea and hypopnea, irrespective of symptoms of sleepiness.

            Estimation of the clinically diagnosed proportion of sleep apnea syndrome in middle-aged men and women.

            The proportion of sleep apnea syndrome (SAS) in the general adult population that goes undiagnosed was estimated from a sample of 4,925 employed adults. Questionnaire data on doctor-diagnosed sleep apnea were followed up to ascertain the prevalence of diagnosed sleep apnea. In-laboratory polysomnography on a subset of 1,090 participants was used to estimate screen-detected sleep apnea. In this population, without obvious barriers to health care for sleep disorders, we estimate that 93% of women and 82% of men with moderate to severe SAS have not been clinically diagnosed. These findings provide a baseline for assessing health care resource needs for sleep apnea.

              Sleep apnea as an independent risk factor for all-cause mortality: the Busselton Health Study.

              Previously published cohort studies in clinical populations have suggested that obstructive sleep apnea (OSA) is a risk factor for mortality associated with cardiovascular disease. However, it is unknown whether sleep apnea is an independent risk factor for all-cause mortality in a community-based sample free from clinical referral bias. Residents of the Western Australian town of Busselton underwent investigation with a home sleep apnea monitoring device (MESAM IV). OSA was quantified via the respiratory disturbance index (RDI). Mortality status was determined in 397/400 participants (99.3%) after up to 14 years (mean follow-up 13.4 years) by data matching with the Australian National Death Index and the Western Australian Death Register. Univariate analyses and multivariate Cox proportional hazards modelling were used to ascertain the association between sleep apnea and mortality after adjustment for age, gender, body mass index, mean arterial pressure, total cholesterol, high-density lipoprotein cholesterol, diabetes, and medically diagnosed angina in those free from heart attack or stroke at baseline (n = 380). Among the 380 participants, 18 had moderate-severe OSA (RDI > or = 15/hr, 6 deaths) and 77 had mild OSA(RDI 5 to < 15/hr, 5 deaths). Moderate-to-severe OSA was independently associated with greater risk of all-cause mortality (fully adjusted hazard ratio [HR] = 6.24, 95% CL 2.01, 19.39) than non-OSA (n = 285, 22 deaths). Mild OSA (RDI 5 to < 15/hr) was not an independent risk factor for higher mortality (HR = 0.47, 95% CL 0.17, 1.29). Moderate-to-severe sleep apnea is independently associated with a large increased risk of all-cause mortality in this community-based sample.
