PURPOSE:  Bangladesh is a developing country in south-east Asia where there is no polysomnography (PSG) facilities even in a tertiary care hospital. This pilot study reports about snoring and sleep disordered breathing (SDB) for the first time among Bangladeshi population.

METHODS:  The Berlin questionnaire and Epworth sleepiness scale (ESS) were used to identify patients of snoring and SDB. Subjects [N: 96; sex ( male/female): 66/30]; age [( yrs, m ± SD):33 ± 8] were selected from Chest clinic and Medicine OPD of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. The Berlin questionnaire and ESS were translated and validated into Bengali language for easy interpretation.

RESULTS:  Snoring was observed in 35%, while daytime sleepiness in 46%. BMI (kg/m2) and neck circumference (inch) was 23 ± 3 and 14.3 ± 3.7 respectively. Both witness apnea and waketime tiredness was in 25%. Where as drowsiness during chatting (replaced for drowsy driving) was seen in 8%. ESS score revealed significant differences between groups having snoring (5.06 ± 0.07 Vs 4.72 ± 0.016, P=0.016), witness apnea (11.17 ± 4.02 Vs 8.63 ± 5.18, P=0.032), tiredness ( 11.75 ± 4.32 Vs 8.42 ± 4.91, P=0.042), daytime sleepiness ( 11.86 ± 4.10 Vs 7.04 ± 4.57, P= <0.001), drowsiness (12.50 ± 2.20 Vs 7.59 ± 4.00, P= <0.001) and HTN ( 11.25 ± 4.56 Vs 8.81 ± 5.01, P= 0.19) when compared with respective counterparts. About 41% subjects showed ESS score ≥ 11. Regression analysis of BMI, neck circumference, snoring, witness apnea, tiredness, daytime sleepiness, drowsiness and HTN for significant ESS score (≥ 11) showed daytime sleepiness ( P < 0.001) as independent predictor.

CONCLUSION:  Snoring, daytime sleepiness, waketime tiredness are not less frequently seen in Bangladeshi population. Study encompassing large population with PSG evaluation could illuminate the problem.

CLINICAL IMPLICATIONS:  Awareness of SDB, an unidentified problem in Bangladesh, can help overall health care and curtail accidents in vehicles and industries, attributable to sleep apnea.
