Prevalence of rapid eye movement sleep related obstructive sleep apnea (rem related osa) in Patients with sleep disordered breathinga Cross sectional study

Abstract

ABSTRACT Background: Rapid Eye Movement-related Obstructive Sleep Apnea (REM OSA) represents a distinct subtype of sleep-disordered breathing (SDB), often characterized by increased symptom burden and a unique clinical profile. While the global recognition of REM OSA is expanding, its prevalence, demographic correlations, and clinical manifestations remain understudied in Indian populations. Identifying reliable clinical predictors and validating the utility of commonly used screening tools is essential for early diagnosis and optimized management. Objectives: The primary objective of the study was to determine the prevalence of REM OSA among patients with sleep-disordered breathing, as per both strict and broad diagnostic criteria. The secondary Objective of the study is to assess the correlation of Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), Berlin Questionnaire, and STOP-BANG score with overall AHI and the diagnosis of REM OSA.
