Snoring can impair lifestyle and cause late cardiopulmonary complications. Early detection of snoring and timely intervention during adolescence can avoid complications. A single center prospective cross-sectional study was conducted in 548 undergraduate 17-25 years old undergraduate medical students of CSM Medical University, Lucknow, who were interviewed on the basis of the modified Berlin Questionnaire along with their room-partners describing their snoring habits. Ninety-seven (17.7%) subjects were found to be snorers. Risk factors viz. day time sleepiness (European Stroke Scale (ESS) scores), smoking habits, alcohol intake, neck size and BMI were observed. The proportion of males, smokers, BMI, neck size and ESS scores were significantly (p < 0.001) higher in snorers than non snorers. Logistic regression found sex (OR = 5.73, 95% CI = 2.11-15.61), smoking (OR = 2.20, 95% CI = 0.97-5.62), BMI (OR = 3.16, 95% CI = 1.09-7.36) and neck size (OR = 2.03, 95% CI = 0.79-6.35) as significant (p < 0.01) independent risk factors for snoring. A clinically significant form of Sleep Disordered Breathing (Habitual snoring, ESS score ≥ 11 and BMI ≥ 25 kg/m2) was suspected in 4 (0.7%) students. The findings of this study may also be validated in the general population. The study concluded that male undergraduate medical students are at a high risk for developing snoring habits.
