Methodology The cross-sectional study was carried out in Annamalai nagar municipality located in Cuddalore district of Tamilnadu. The study population included all the persons residing in Annamalai nagar municipality aged more than 30 years. The study was conducted between 10th September 2019 to 20th September 2019.

Ten percent of the study participants were smokers and almost thirteen percentage were alcoholics. Thirty-seven study participants (20%) were found to be at high risk for sleep apnoea. At the end of cross tabulation, three variables namely age, income and being alcoholic were found to have significant association with high risk of sleep apnoea.
