ABSTRACT

Back ground Obstructive sleep apnoea was prevalent in 9 to 25% of the general adult population and is also linked to cardiovascular, cerebrovascular and metabolic disorders. Objective 1. To find out prevalence of high risk of sleep apnoea among population aged more than 30 years residing in Annamalai nagar municipality. 2. To find out the association between selected socio demographic, behavioural risk factors and risk of OSA. 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. STOP BANG questionnaire was used to screen the persons for the risk of sleep apnoea. The sample size calculated was 186. SPSS version 23 was used for statistical analysis. Results Out of the population surveyed, 53.7% were less than 50 years of age. Females formed 69.4% of the study participants. In about 50.5% of the study participants, the per capita monthly income was found to be less than 5000 INR. 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. Conclusion Two factors mainly alcoholism and lower income were associated with high risk of sleep apnoea. Interventions targeting alcoholism and general improvement of socio-economic status can aid in decreasing risk of sleep apnoea in the study population.
