PURPOSE:  To know prevalence estimates for key symptoms and features that can indicate the presence of obstructive sleep apnea(OSA) in Indian population.

METHODS:  Single centre cross sectional study done from August 2003 to July 2004 in consecutive apparently healthy attendants of 25-64 years age group coming to outdoor of Department of Pulmonary Medicine, King George’s Medical University, Lucknow, India. We recorded data on a pre-designed proforma and took interview on the basis of pre-tested Berlin Questionnaire with some relevant modifications.

RESULTS:  Out of 816 subjects approached, 702 responded. Out of 702, 452(64.4%)were males. Mean age was 42.7 ± 10.4 years; mean neck circumference was 13.6 ± 1.2 inch, mean BMI was 23.8 ± 4.2 kg/m2. 31.1%(218/702) were snorers. The loud snorers were17.4%, and 60.5% of them were at high risk for OSA. Among snorers 22.9% bothered other people and 46.0% of them were at high risk for OSA. Out of 702, 6.0% had morning tiredness or sleepy awakening (≥ 3-4 times /wk) and 52.4% of them were at high risk for OSA, 5.1% had wake time tiredness and 61.1% of them were at high risk for OSA. Out of 702, 45.3% either did not know to drive or never needed driving and only 54.7 % used to drive. Among persons who use to drive 2.1% had drowsiness behind the wheel (≥ 3-4 times/wk) and 75% of them were at high risk for OSA. Out of 702, 13.0% were obese and 19.8% of them were at high risk for OSA. Overall there were 3.7% (26/702) were at high risk for OSA(qualified for 2 or more category symptoms of Berlin questionnaire) .

CONCLUSION:  Obstructive sleep apnea is a common disease and there is high demand of its awareness, evaluation, diagnosis and management in countries like India.

CLINICAL IMPLICATIONS:  There is need of relevant modification of Berlin Questionnaire for countries like India as half of our population either do not know to drive ored not to drive.
