Abstract :

 

Introduction: The burden of obstructive sleep apnoea syndrome (OSAS) is rapidly increasing in developing countries like India since the last decade.

Background: To know the prevalence estimates for key symptoms and features that can indicate the presence of OSAS in Indian population.

Material and Methods: A single centre cross-sectional study was conducted from August 2003 to July 2004 on consecutive apparently healthy attendants in age group of 25-64 years coming to outdoor of Department of Pulmonary Medicine, King George Medical University, Lucknow, India. We recorded data on a pre-designed proforma and took interview based on pre-tested Berlin Questionnaire (BQ) with some relevant modifications. Epworth sleepiness scale (ESS) score was also assessed for excessive daytime sleepiness (EDS). We also evaluated for some risk factors like smoking, alcoholism and use of sedative or tranquilizers.

Results: Out of 816 subjects approached, 702 (86%) were finally included in study (mean age 42.67 years; men n = 452 (64.4%), women n= 250 (35.6%). Out of these 3.7% (4.2% men, 2.8% women) were found to be at high risk for OSAS. Out of total studied population, 11.72% men and 14.8% women were obese (BMI ³ 30 kg/m²) and 19.8% of obese population were at high risk for OSAS. Among high-risk patients for OSAS, 42.3% had hypertension. The mean ESS score was 5.17 ± 2.58. Out of 702 subjects, 13 had clinically significant form of OSAS defined as snoring at least 3-4 times/week, EDS (ESS score ³ 11) and obesity (BMI ³ 30 kg/m²), giving overall prevalence of OSAS at least 1.6% comprising 2.4% men and 0.8% women. Statistically significant risk-factors found for OSAS were obesity, large neck size (³17 inch in male or ³15 inch in female), alcoholism and sedatives/ tranquilizers use. Male gender and smoking were associated with increased risk for OSAS but with no statistical significance. 

Conclusion: OSAS is a common disease and there is high demand for its awareness, evaluation, diagnosis and management. Symptoms category 2 of BQ may be replaced with use of ESS score in developing countries like India
