Prevalence and risk factors of people at-risk of obstructive sleep apnea in a rural community of Odisha, India: a community based cross-sectional study.

Background: Obstructive sleep apnea (OSA) is a progressive sleep disordered breathing condition characterized by repeated episodes of upper airway collapse during sleep. Despite being the most common sleep apnea, it often remains undiagnosed and untreated, especially in rural communities. There is a paucity of literature estimating the prevalence of the disease and associated risk factors from the rural population of Odisha.
