“…For the 135 individuals assessed in the present study, the scores obtained on the ESS-BR showed internal consistency similar to that of translations validated elsewhere, (24)(25)(26)(27)(28) despite the cultural and language differences among the populations analyzed. Comparing the ESS-BR scores obtained in the present study with those obtained in studies applying the original ESS, we found the scores to be similar for the control and OSAHS groups.…”

“…The relationship between snoring and EDS has previously been suggested. (26) In the present study, this difference might be attributable due to a selection bias, since most of the patients in the primary snoring group were referred for polysomnography due to clinical suspicion of OSAHS. In addition, some of these patients might have had increased airway resistance.…”

“…(25)(26)(27)(28) In one study, (19) the ESS scores were significantly higher for patients with severe OSAHS than for those with mild or moderate OSAHS (p < 0.001), although no statistically significant difference was found between the mild and moderate forms. Unlike other validation studies, the present study evaluated only individuals submitted to polysomnography, which enhanced the stringency of the selection of the groups.…”

Portuguese-language version of the Epworth sleepiness scale: validation for use in Brazil

et al. 2009

Objective: The aim of this study was to develop a Portuguese-language version of the Epworth sleepiness scale (ESS) for use in Brazil. Methods: The steps involved in creating the ESS in Brazilian Portuguese (ESS-BR) were as follows: translation; back-translation; comparison (by a committee) between the translation and the back-translation; and testing in bilingual individuals. The ESS-BR was applied to a group of patients who were submitted to overnight polysomnography in order to identify obstructive sleep apnea-hypopnea syndrome (OSAHS), insomnia and primary snoring. A control group was composed of subjects with a history of normal sleep habits, without reported snoring. Results: A total of 114 patients and 21 controls were included. The 8-item scores of the ESS-BR had an overall reliability coefficient of 0.83. The study group was composed of 59 patients with OSAHS, 34 patients with primary snoring and 21 patients with insomnia. One-way ANOVA demonstrated significant differences in ESS-BR scores among the four diagnostic groups (p < 0.001). Post-hoc tests between groups showed that the ESS-BR scores of the patients with insomnia did not differ from those of the controls (p > 0.05). The ESS-BR scores were significantly higher for OSAHS patients and for primary snorers than for controls (p < 0.05). In addition, the scores for OSAHS patients were significantly higher than were those for primary snorers (p < 0.05). Conclusions: The results of the present study demonstrate that the ESS-BR is a valid and reliable instrument for the assessment of daytime sleepiness, equivalent to its original version when applied to individuals who speak Brazilian Portuguese.Keywords: Validation studies; Sleep disorders; Cross-cultural comparison; Disorders of excessive somnolence. ResumoObjetivo: Desenvolver uma versão da escala de sonolência de Epworth (ESE) para o português para uso no Brasil. Métodos: A versão no português do Brasil (ESE-BR) foi desenvolvida de acordo com as seguintes etapas: tradução; retrotradução; comparação entre a tradução e a retrotradução (por um comitê); e aplicação em indivíduos bilín-gues. A ESE-BR foi aplicada a um grupo de pacientes submetidos à polissonografia de noite inteira para identificar síndrome da apneia-hipopneia obstrutiva do sono (SAHOS), insônia e ronco primário. Um grupo controle foi composto de indivíduos com história de hábitos normais de sono, sem ronco aparente. Resultados: Um total de 114 pacientes e 21 controles foram incluídos. Os 8 itens do ESE-BR tiveram um coeficiente de confiabilidade total de 0,83. O grupo em estudo foi composto por 59 pacientes com SAHOS, 34 pacientes com ronco primário e 21 pacientes com insônia. One-way ANOVA demonstrou diferenças significativas nos escores do ESE-BR entre os quatro grupos diagnósticos (p < 0,001). Testes post hoc entre grupos pareados mostraram que os escores do ESE-BR para insones não diferiram daqueles dos controles (p > 0,05). Os escores dos pacientes com SAHOS e nos roncadores primários foram significativamente maiores que os...

“…The ESS and BQ were chosen due to their frequent use in the obstetric OSA literature, and possibly the population (12)(13)(14)(15)(16). The ESS has been validated in the Spanish language and in Hispanic populations (17)(18)(19). At study initiation, neither questionnaire had been validated in a gravid population; a separate analysis of this study sought to assess the validity of these two questionnaires in pregnancy.…”

Association of adverse perinatal outcomes with screening measures of obstructive sleep apnea

Objective-This prospective observational study explored the association of hypertensive disorders of pregnancy and small-for-gestational age (SGA) with obstructive sleep apnea (OSA) as determined by screening measures for OSA and sleep studies.Study Design-Two symptom-based screening questionnaires, the Berlin Questionnaire (BQ) and the Epworth Sleepiness Scale (ESS), were administered to enroll 1509 gravidae. Screen positive subjects were referred for polysomnography (PSG). The primary outcome was the occurrence of either gestational hypertension or preeclampsia.[a1]Generalized linear models (GLM) were used to estimate the relative risks of associations.Results-1157 subjects were available for outcomes analysis. Screening positive on the BQ was positively associated with hypertensive disorders in GLM models (aRR=1.90, 95%CI 1.52-2.37).Conclusion-In this large prospective trial, GLM modeling suggest that the BQ but not the ESS demonstrated significant association with measured adverse pregnancy outcomes, and specific items predicted these outcomes better than others. However, causative association of BQ with OSA cannot be assumed.

“…This scale has been used in different studies of genetics of circadian phenotypes [14-16]. We used the validated version in Spanish of the ESS [11], that has also been used before in a Colombian sample [17]. The internal consistency (Cronbach’s alpha) in this sample was 0.716.…”

Polymorphisms in human clock genes have been evaluated as potential factors influencing circadian phenotypes in several populations. There are conflicting results for the association of a VNTR in the PER3 gene and diurnal preference in different studies. The objective of this study was to investigate the association between diurnal preference and daytime somnolence with the PER3 VNTR polymorphism (rs57875989) in healthy subjects from Colombia, a Latin American population.A total of 294 undergraduate university students from Bogotá, Colombia participated in this study. Two validated self-report questionnaires, the Composite Scale of Morningness (CSM) and the Epworth Sleep Scale (ESS) were used to assess diurnal preference and daytime somnolence, respectively. Individuals were genotyped for the PER3 VNTR using conventional PCR. Statistical comparisons were carried out with PLINK and SNPStats programs.The PER3 VNTR polymorphism was not associated with either diurnal preference or daytime somnolence in this population. No significant differences in mean scores for those scales were found between PER3 VNTR genotypes. In addition, there were no differences in allelic or genotypic frequencies between chronotype categories. This is consistent with several negative findings in other populations, indicating that the proposed influence of this polymorphism in diurnal preference, and related endophenotypes of neuropsychiatric importance, needs further clarification. This is the first report of molecular genetics of human circadian phenotypes in a Spanish-speaking population.

Validación de la Escala de Somnolencia de Epworth

Abstract: ESS-VC compared well with the original version. It is well adapted to urban life conditions in the Colombian adult population, reliable, valid and sensitive to reported changes. It had clinically and statistically significant correlation with polysomnography.
