“…This concurs with findings of BERRY et al [18], who reported that 0.5 g alcohol?kg -1 did not notably change breathing patterns during sleep. In contrast, moderate doses of alcohol (0.5-1 g?kg -1 ) increased the AHI without influencing apnoea length or oxygen desaturation [19]. Time spent in a supine position did not significantly affect the ODI variability factor.…”

The current study investigated the night-to-night variability and diagnostic accuracy of the oxygen desaturation index (ODI), as measured by ambulatory monitoring, in the diagnosis of mild and moderate obstructive sleep apnoea-hypopnoea syndrome.To assess the variability of the ODI, 35 patients were monitored at home during 7 consecutive nights by means of a portable recording device, the MESAM-IV1. The ODI variability factor and the influence of age, body mass index (BMI), alcohol, and body position were assessed. Furthermore, the diagnostic accuracy of the MESAM-IV was measured by comparison with polysomnographical outcomes in 18 patients.During home recording, the median ODI was 10.9 (interquartile range: 5.8-16.1) across the patients. Although the reliability of the ODI was adequate, the probability of placing the patient in the wrong severity category (ODI f15 or ODI w15) when only one single recording was taken is 14.4%. ODI variability was not significantly influenced by age, BMI, time spent in a supine position, or mild dosages of alcohol. A good correlation was found between the apnoea-hypopnoea index and the ODI.In conclusion, the findings suggest that the diagnostic accuracy of the MESAM-IV is strong, since the oxygen desaturation index is correlated with the apnoea-hypopnoea index. In most obstructive sleep apnoea-hypopnoea syndrome patients, oxygen desaturation index variability is rather small, and screening could be reliably based on single 1-night recordings.

“…These authors also highlighted that alcohol has a synergistic relationship with sleep deprivation, which increases chances of road accidents and reduces the academic performance of university students (7,8) . Studies carried out on adults in turn highlighted a statistically significant association between alcohol use and the development of sleep apnoea, poor sleep quality and sleep problems ( 9,(21)(22) .…”

“…It also affects lung function and causes inflammation of the airways, generating a predisposition to snoring and apnoea. Smoking is still associated with disturbances in the structure of sleep, such as an increase in latency, excessive drowsiness during the day and a reduction in sleep (8)(9)(10) efficiency.…”

Health indicators associated with poor sleep quality among university students RESUMEN Objetivo: Asociar la calidad del sueño de los universitarios brasileños con los indicadores de salud. Método: Estudio transversal desarrollado con una muestra aleatoria de 662 estudiantes universitarios de Fortaleza, Brasil. Fueron recogidos datos sociodemográficos, indicadores de salud (tabaquismo, alcoholismo, sedentarismo, estado nutritivo y niveles séricos de colesterol) y el Índice de Calidad del Sueño de Pittsburgh mediante un cuestionario autoadministrado. Las muestras sanguí-neas fueron analizadas en un laboratorio clínico y para evaluar la magnitud de las asociaciones se adoptó la Regresión de Poisson. Resultados: En los universitarios que fuman diariamente la ocurrencia de mala calidad del sueño fue superior en su relación con los no fumadores (p<0,001). Sin embargo, la razón de prevalencia fue de aproximadamente 1. Conclusión: Las probabilidades de presentar mala calidad del sueño fueron prácticamente idénticas entre tabaquistas y etilistas. DESCRIPTORES ABSTRACTObjective: to associate the sleep quality of Brazilian undergraduate students with health indicators. Method: A cross-sectional study was developed with a random sample of 662 undergraduate students from Fortaleza, Brazil. The demographic data, Pittsburgh Sleep Quality Index and health data indicators (smoking, alcoholism, sedentary lifestyle, nutritional condition and serum cholesterol) were collected through a self-administered questionnaire. Blood was collected at a clinical laboratory. In order to estimate the size of the associations, a Poisson Regression was used. Results: For students who are daily smokers, the occurrence of poor sleep was higher than in nonsmokers (p<0.001). Prevalence rate values were nevertheless close to 1. Conclusion: The likelihood of poor sleep is almost the same in smokers and in alcoholics.

“…Several studies have found a significant association between OSAS and measures of excess body weight [1,11,13,[30][31][32][33][34][35][36][37][38][39]. Many studies in which defined quantities of alcohol were administered to healthy subjects or patients with OSAS before bedtime have demonstrated harmful effects on nocturnal respiration including increased number and duration of hypopnea and apnea events [40][41][42][43][44][45]. Many cross-sectional epidemiological studies of OSAS have found positive associations with cigarette smoking [4,[46][47][48].…”

Obstructive Sleep Apnea Syndrome (OSAS) has been recognised as a major cause of morbidity and mortality in developing countries like India. There is still a paucity of Indian studies regarding the prevalence of OSAS. The current single centre prospective cross-sectional study was undertaken to know prevalence estimates for key symptoms and features that can indicate the presence of OSAS in an Indian population. A survey was conducted on subjects with age groups ≥25 years at King George's Medical University, Lucknow, Uttar Pradesh, India from August 2009 to July 2011. Data was recorded during the interview on the basis of Berlin Questionnaire (BQ). Risk factors for OSAS were also evaluated. Risk group categorization for OSAS was done with the help of a questionnaire and overnight polysomnography was performed in each group to measure apnea and hypopnea index (AHI). Out of 1816 subjects, 1512 (response rate 83.3%) finally participated in the survey with mean age 42.6±11.2 years, males 67.9% and females 32.1%. Of them 6.2% were found to be at high-risk OSAS; 12.2% were obese (Body Mass Index ≥30 kg/m 2 ) and 33.5% of the obese population were at high-risk OSAS. Among high-risk patients with OSAS, 62.4% had hypertension. Statistically significant and independent risk factors found for OSAS were obesity, large neck size, alcoholism and use of sedatives/tranquillizers. Highrisk category predicted an AHI ≥5 with a sensitivity of 86.3% (95% CI 73.1-93.8), specificity of 93.1% (95% CI 89.1-95.7), positive and negative predictive values of 70.9% (95% CI 57.9-81.4) and 97.2% (95% CI 94.1-98.8) respectively. It can be concluded that BQ questionnaire can still be used as a pre-assessment tool for predicting persons at risk for OSAS in clinical practice. Further studies on estimation of prevalence of OSAS by applying BQ are warranted in near future from other regions of India.
